e50da555ca sound updates for 6.15-rc1 
We've received lots of commits at this time, as a result of various
 cleanup and refactoring works as well as a few new drivers and the
 generic SoundWire support.  Most of changes are device-specific,
 little about the core changes.  Some highlights below:
 
 Core:
 * A couple of (rather minor) race fixes in ALSA sequencer code
 * A regression fix in ALSA timer code that may lead to a deadlock
 
 ASoC:
 * A large series of code conversion to use modern terminology for the
   clocking configuration
 * Conversions of PM ops with the modern macros in all ASoC drivers
 * Clarification of the control operations
 * Prepartory work for more generic SoundWire SCDA controls
 * Support for AMD ACP 7.x, AWINC WM88166, Everest ES8388, Intel AVS
   PEAKVOL and GAIN DSP modules Mediatek MT8188 DMIC, NXP i.MX95,
   nVidia Tegra interconnects, Rockchip RK3588 S/PDIF, Texas
   Instruments SN012776 and TAS5770L, and Wolfson WM8904 DMICs
 
 Others:
 * Conversions of PM ops with the modern macros in the rest drivers
 * USB-audio quirks and fixes for Presonus Studio, DJM-A9, CME
 * HD-audio quirks and fixes ASUS, HP, Lenovo, and others
 
 Note that the PR contains some changes from the tip tree for AMD code,
 and it might give some merge conflict due to the rebase afterwards.

GPIO core:
 - add sanitization of return values of GPIO provider callbacks so that invalid
   ones don't get propagated to user-space
 - add new variants of the line setter callbacks for GPIO providers that return
   an integer and allow to indicate driver errors to the GPIO core
 - change the interface of all gpiod_set_value() variants to return an integer
   thus becoming able to indicate failures in the underlying layer to callers
 - drop unneeded ERR_CAST in gpiolib-acpi
 - use for_each_if() where applicable
 - provide gpiod_multi_set_value_cansleep() as a new, simpler interface to
   gpiod_set_array_value_cansleep() and use it across several drivers treewide

 - don't build HTE (hardware timestamp engine) GPIO code with the HTE subsystem
   disabled in Kconfig
 - unduplicate calls to gpiod_direction_input_nonotify()
 - rework the handling of the valid_mask property of GPIO chips: don't allow
   drivers to set it as it should only be handled by GPIO core and start
   actually enforcing it in GPIO core for *all* drivers, not only the ones
   implementing a custom request() callback
 - get the `ngpios` property from the fwnode of the GPIO chip, not its device in
   order to handle multi-bank GPIO chips

Pull gpio updates from Bartosz Golaszewski:
 "There are no new drivers this time but several changes to the core
  GPIO framework and various driver updates.

  This release cycle, we're starting a relatively straightforward but
  tedious rework of the GPIO consumer API: for historical reasons, the
  gpiod_set_value() variants would return void. Not only that but the
  GPIO provider interface does not even allow drivers to return a value
  to GPIO core. This is because initial GPIO controllers would be MMIO
  based and could not fail. We've had I2C, SPI and USB controllers for
  years too but no way of indicating failures to callers.

  This changes the consumer interface, adds new provider callbacks and
  starts converting the drivers under drivers/gpio/ to using them. Once
  this gets upstream, we'll keep on converting GPIO drivers that live
  elsewhere and once there are no more users of the old callbacks, we'll
  remove them and rename the new ones to the previous name. I imagine
  the last step would happen in one sweeping change like what you did
  for the remove_new() -> remove() renaming.

  We've also addressed an issue where invalid return values from GPIO
  drivers would get propagated to user-space by adding some
  GPIO-core-level sanitization. Again: not a complex change but way
  overdue.

  Other than that: lots of driver and core refactoring, DT-bindings
  changes and some other minor changes like coding style fixes or header
  reordering.

  GPIO core:
   - add sanitization of return values of GPIO provider callbacks so
     that invalid ones don't get propagated to user-space
   - add new variants of the line setter callbacks for GPIO providers
     that return an integer and allow to indicate driver errors to the
     GPIO core
   - change the interface of all gpiod_set_value() variants to return an
     integer thus becoming able to indicate failures in the underlying
     layer to callers
   - drop unneeded ERR_CAST in gpiolib-acpi
   - use for_each_if() where applicable
   - provide gpiod_multi_set_value_cansleep() as a new, simpler
     interface to gpiod_set_array_value_cansleep() and use it across
     several drivers treewide
   - reduce the number of atomic reads of the descriptor flags in
     gpiolib debugfs code
   - simplify for_each_hwgpio_in_range() and
     for_each_requested_gpio_in_range()
   - add support for three-cell GPIO specifiers in GPIO OF code
   - don't build HTE (hardware timestamp engine) GPIO code with the HTE
     subsystem disabled in Kconfig
   - unduplicate calls to gpiod_direction_input_nonotify()
   - rework the handling of the valid_mask property of GPIO chips: don't
     allow drivers to set it as it should only be handled by GPIO core
     and start actually enforcing it in GPIO core for *all* drivers, not
     only the ones implementing a custom request() callback
   - get the `ngpios` property from the fwnode of the GPIO chip, not its

47618bc875 spi: Updates for v6.15 
The biggest change for SPI this release is the addition of offload
 support from David Lechner, allowing the hardware to trigger SPI
 transactions autonomously.  The initial use case is for triggering IIO
 operations but there are other applications where having the hardware
 ready to go at a minimal signal is useful for synchronising with
 external inputs (eg, interrupt handling) or reducing latency (eg, CAN
 networking).  Otherwise there's the usual fixes, improvements and
 cleanups, plus support for a bunch of new devices.
 
  - Support for offloaing support from David Lechner.
  - Support for GOcontrol1 Moduline modules, Mediatek MT7988, NXP i.MX94,
    Qualcomm SPI NAMD, Rockchip RK3562, Sophogo SG2044 and ST STM32 OSPI.

e2ae6e14d7 regulator: Updates for v6.15 
This has been a very quiet release, we've got support for one device
 added, another removed, and some smaller fixes and API improvements.
 The main thing of note is the rework of the PCA9450 LDO5 handling:
 
  - A rework of the handling of LDO5 on the PCA9450, this was quite wrong
    in how it handled the SD_VSEL conrol and only worked for some system
    designs.  This includes a DTS update since there was a not quite ABI
    compatible change as part of the fix.
  - A devres change introducing devm_kmemdup_array() was pulled in so it
    could be used with some regulator conversions to that function, this
    pulled in some other devres and IIO stuff that was part of the same pull
    request.
  - Removal of the PCF50633 driver, the SoC for the OpenMoko platform
    that used it has been removed.
  - Support for the NXP PF9453.

ee6740fd34 CRC updates for 6.15 
Another set of improvements to the kernel's CRC (cyclic redundancy
 check) code:
 
 - Rework the CRC64 library functions to be directly optimized, like what
   I did last cycle for the CRC32 and CRC-T10DIF library functions.
 
 - Rewrite the x86 PCLMULQDQ-optimized CRC code, and add VPCLMULQDQ
   support and acceleration for crc64_be and crc64_nvme.
 
 - Rewrite the riscv Zbc-optimized CRC code, and add acceleration for
   crc_t10dif, crc64_be, and crc64_nvme.
 
 - Remove crc_t10dif and crc64_rocksoft from the crypto API, since they
   are no longer needed there.
 
 - Rename crc64_rocksoft to crc64_nvme, as the old name was incorrect.
 
 - Add kunit test cases for crc64_nvme and crc7.
 
 - Eliminate redundant functions for calculating the Castagnoli CRC32,
   settling on just crc32c().
 
 - Remove unnecessary prompts from some of the CRC kconfig options.
 
 - Further optimize the x86 crc32c code.

Pull selinux updates from Paul Moore:

 - Add additional SELinux access controls for kernel file reads/loads

   The SELinux kernel file read/load access controls were never updated
   beyond the initial kernel module support, this pull request adds
   support for firmware, kexec, policies, and x.509 certificates.

 - Add support for wildcards in network interface names

   There are a number of userspace tools which auto-generate network
   interface names using some pattern of <XXXX>-<NN> where <XXXX> is a
   fixed string, e.g. "podman", and <NN> is a increasing counter.
   Supporting wildcards in the SELinux policy for network interfaces
   simplifies the policy associted with these interfaces.

 - Fix a potential problem in the kernel read file SELinux code

   SELinux should always check the file label in the
   security_kernel_read_file() LSM hook, regardless of if the file is
   being read in chunks. Unfortunately, the existing code only
   considered the file label on the first chunk; this pull request fixes
   this problem.

   There is more detail in the individual commit, but thankfully the
   existing code didn't expose a bug due to multi-stage reads only
   taking place in one driver, and that driver loading a file type that
   isn't targeted by the SELinux policy.

 - Fix the subshell error handling in the example policy loader

   Minor fix to SELinux example policy loader in scripts/selinux due to
   an undesired interaction with subshells and errexit.

Pull lsm updates from Paul Moore:

 - Various minor updates to the LSM Rust bindings

   Changes include marking trivial Rust bindings as inlines and comment
   tweaks to better reflect the LSM hooks.

 - Add LSM/SELinux access controls to io_uring_allowed()

   Similar to the io_uring_disabled sysctl, add a LSM hook to
   io_uring_allowed() to enable LSMs a simple way to enforce security
   policy on the use of io_uring. This pull request includes SELinux
   support for this new control using the io_uring/allowed permission.

 - Remove an unused parameter from the security_perf_event_open() hook

   The perf_event_attr struct parameter was not used by any currently
   supported LSMs, remove it from the hook.

 - Add an explicit MAINTAINERS entry for the credentials code

   We've seen problems in the past where patches to the credentials code
   sent by non-maintainers would often languish on the lists for
   multiple months as there was no one explicitly tasked with the
   responsibility of reviewing and/or merging credentials related code.

   Considering that most of the code under security/ has a vested
   interest in ensuring that the credentials code is well maintained,
   I'm volunteering to look after the credentials code and Serge Hallyn
   has also volunteered to step up as an official reviewer. I posted the
   MAINTAINERS update as a RFC to LKML in hopes that someone else would
   jump up with an "I'll do it!", but beyond Serge it was all crickets.

 - Update Stephen Smalley's old email address to prevent confusion

   This includes a corresponding update to the mailmap file.

Pull power management updates from Rafael Wysocki:
 "These are dominated by cpufreq updates which in turn are dominated by
  updates related to boost support in the core and drivers and
  amd-pstate driver optimizations.

  Apart from the above, there are some cpuidle updates including a
  rework of the most recent idle intervals handling in the venerable
  menu governor that leads to significant improvements in some
  performance benchmarks, as the governor is now more likely to predict
  a shorter idle duration in some cases, and there are updates of the
  core device power management code, mostly related to system suspend
  and resume, that should help to avoid potential issues arising when
  the drivers of devices depending on one another want to use different
  optimizations.

  There is also a usual collection of assorted fixes and cleanups,
  including removal of some unused code.

edb0e8f6e2 ARM: 
* Nested virtualization support for VGICv3, giving the nested
 hypervisor control of the VGIC hardware when running an L2 VM
 
 * Removal of 'late' nested virtualization feature register masking,
   making the supported feature set directly visible to userspace
 
 * Support for emulating FEAT_PMUv3 on Apple silicon, taking advantage
   of an IMPLEMENTATION DEFINED trap that covers all PMUv3 registers
 
 * Paravirtual interface for discovering the set of CPU implementations
   where a VM may run, addressing a longstanding issue of guest CPU
   errata awareness in big-little systems and cross-implementation VM
   migration
 
 * Userspace control of the registers responsible for identifying a
   particular CPU implementation (MIDR_EL1, REVIDR_EL1, AIDR_EL1),
   allowing VMs to be migrated cross-implementation
 
 * pKVM updates, including support for tracking stage-2 page table
   allocations in the protected hypervisor in the 'SecPageTable' stat
 
 * Fixes to vPMU, ensuring that userspace updates to the vPMU after
   KVM_RUN are reflected into the backing perf events
 
 LoongArch:
 
 * Remove unnecessary header include path
 
 * Assume constant PGD during VM context switch
 
 * Add perf events support for guest VM
 
 RISC-V:
 
 * Disable the kernel perf counter during configure
 
 * KVM selftests improvements for PMU
 
 * Fix warning at the time of KVM module removal
 
 x86:
 
 * Add support for aging of SPTEs without holding mmu_lock.  Not taking mmu_lock
   allows multiple aging actions to run in parallel, and more importantly avoids
   stalling vCPUs.  This includes an implementation of per-rmap-entry locking;
   aging the gfn is done with only a per-rmap single-bin spinlock taken, whereas
   locking an rmap for write requires taking both the per-rmap spinlock and
   the mmu_lock.
 
   Note that this decreases slightly the accuracy of accessed-page information,
   because changes to the SPTE outside aging might not use atomic operations
   even if they could race against a clear of the Accessed bit.  This is
   deliberate because KVM and mm/ tolerate false positives/negatives for
   accessed information, and testing has shown that reducing the latency of
   aging is far more beneficial to overall system performance than providing
   "perfect" young/old information.
 
 * Defer runtime CPUID updates until KVM emulates a CPUID instruction, to
   coalesce updates when multiple pieces of vCPU state are changing, e.g. as
   part of a nested transition.
 
 * Fix a variety of nested emulation bugs, and add VMX support for synthesizing
   nested VM-Exit on interception (instead of injecting #UD into L2).
 
 * Drop "support" for async page faults for protected guests that do not set
   SEND_ALWAYS (i.e. that only want async page faults at CPL3)
 
 * Bring a bit of sanity to x86's VM teardown code, which has accumulated
   a lot of cruft over the years.  Particularly, destroy vCPUs before
   the MMU, despite the latter being a VM-wide operation.
 
 * Add common secure TSC infrastructure for use within SNP and in the
   future TDX
 
 * Block KVM_CAP_SYNC_REGS if guest state is protected.  It does not make
   sense to use the capability if the relevant registers are not
   available for reading or writing.
 
 * Don't take kvm->lock when iterating over vCPUs in the suspend notifier to
   fix a largely theoretical deadlock.
 
 * Use the vCPU's actual Xen PV clock information when starting the Xen timer,
   as the cached state in arch.hv_clock can be stale/bogus.
 
 * Fix a bug where KVM could bleed PVCLOCK_GUEST_STOPPED across different
   PV clocks; restrict PVCLOCK_GUEST_STOPPED to kvmclock, as KVM's suspend
   notifier only accounts for kvmclock, and there's no evidence that the
   flag is actually supported by Xen guests.
 
 * Clean up the per-vCPU "cache" of its reference pvclock, and instead only
   track the vCPU's TSC scaling (multipler+shift) metadata (which is moderately
   expensive to compute, and rarely changes for modern setups).
 
 * Don't write to the Xen hypercall page on MSR writes that are initiated by
   the host (userspace or KVM) to fix a class of bugs where KVM can write to
   guest memory at unexpected times, e.g. during vCPU creation if userspace has
   set the Xen hypercall MSR index to collide with an MSR that KVM emulates.
 
 * Restrict the Xen hypercall MSR index to the unofficial synthetic range to
   reduce the set of possible collisions with MSRs that are emulated by KVM
   (collisions can still happen as KVM emulates Hyper-V MSRs, which also reside
   in the synthetic range).
 
 * Clean up and optimize KVM's handling of Xen MSR writes and xen_hvm_config.
 
 * Update Xen TSC leaves during CPUID emulation instead of modifying the CPUID
   entries when updating PV clocks; there is no guarantee PV clocks will be
   updated between TSC frequency changes and CPUID emulation, and guest reads
   of the TSC leaves should be rare, i.e. are not a hot path.
 
 x86 (Intel):
 
 * Fix a bug where KVM unnecessarily reads XFD_ERR from hardware and thus
   modifies the vCPU's XFD_ERR on a #NM due to CR0.TS=1.
 
 * Pass XFD_ERR as the payload when injecting #NM, as a preparatory step
   for upcoming FRED virtualization support.
 
 * Decouple the EPT entry RWX protection bit macros from the EPT Violation
   bits, both as a general cleanup and in anticipation of adding support for
   emulating Mode-Based Execution Control (MBEC).
 
 * Reject KVM_RUN if userspace manages to gain control and stuff invalid guest
   state while KVM is in the middle of emulating nested VM-Enter.
 
 * Add a macro to handle KVM's sanity checks on entry/exit VMCS control pairs
   in anticipation of adding sanity checks for secondary exit controls (the
   primary field is out of bits).
 
 x86 (AMD):
 
 * Ensure the PSP driver is initialized when both the PSP and KVM modules are
   built-in (the initcall framework doesn't handle dependencies).
 
 * Use long-term pins when registering encrypted memory regions, so that the
   pages are migrated out of MIGRATE_CMA/ZONE_MOVABLE and don't lead to
   excessive fragmentation.
 
 * Add macros and helpers for setting GHCB return/error codes.
 
 * Add support for Idle HLT interception, which elides interception if the vCPU
   has a pending, unmasked virtual IRQ when HLT is executed.
 
 * Fix a bug in INVPCID emulation where KVM fails to check for a non-canonical
   address.
 
 * Don't attempt VMRUN for SEV-ES+ guests if the vCPU's VMSA is invalid, e.g.
   because the vCPU was "destroyed" via SNP's AP Creation hypercall.
 
 * Reject SNP AP Creation if the requested SEV features for the vCPU don't
   match the VM's configured set of features.
 
 Selftests:
 
 * Fix again the Intel PMU counters test; add a data load and do CLFLUSH{OPT} on the data
   instead of executing code.  The theory is that modern Intel CPUs have
   learned new code prefetching tricks that bypass the PMU counters.
 
 * Fix a flaw in the Intel PMU counters test where it asserts that an event is
   counting correctly without actually knowing what the event counts on the
   underlying hardware.
 
 * Fix a variety of flaws, bugs, and false failures/passes dirty_log_test, and
   improve its coverage by collecting all dirty entries on each iteration.
 
 * Fix a few minor bugs related to handling of stats FDs.
 
 * Add infrastructure to make vCPU and VM stats FDs available to tests by
   default (open the FDs during VM/vCPU creation).
 
 * Relax an assertion on the number of HLT exits in the xAPIC IPI test when
   running on a CPU that supports AMD's Idle HLT (which elides interception of
   HLT if a virtual IRQ is pending and unmasked).

Merge tag 'edac_updates_for_v6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras

Pull EDAC updates from Borislav Petkov:

 - Add infrastructure support to EDAC in order to be able to register
   memory scrubbing RAS functionality with the kernel and expose sysfs
   nodes to control such scrubbing functionality.

   The main use case is CXL devices which provide different scrubbers
   for their built-in memories so that tools like rasdaemon can
   configure and control memory scrubbing and other, more advanced RAS
   functionality (Shiju Jose and Jonathan Cameron)

 - Add support to ie31200_edac for client SoCs like Raptor Lake-S which
   have multiple memory controllers and out-of-band ECC capability
   (Qiuxu Zhuo)

 - The usual round of cleanups, simplifications and fixlets

317a76a996 Updates for the VDSO infrastructure: 
- Consolidate the VDSO storage
 
     The VDSO data storage and data layout has been largely architecture
     specific for historical reasons. That increases the maintenance effort
     and causes inconsistencies over and over.
 
     There is no real technical reason for architecture specific layouts and

Pull VDSO infrastructure updates from Thomas Gleixner:

 - Consolidate the VDSO storage

   The VDSO data storage and data layout has been largely architecture
   specific for historical reasons. That increases the maintenance
   effort and causes inconsistencies over and over.

   There is no real technical reason for architecture specific layouts
   and implementations. The architecture specific details can easily be
   integrated into a generic layout, which also reduces the amount of
   duplicated code for managing the mappings.

   Convert all architectures over to a unified layout and common mapping
   infrastructure. This splits the VDSO data layout into subsystem
   specific blocks, timekeeping, random and architecture parts, which
   provides a better structure and allows to improve and update the
   functionalities without conflict and interaction.

 - Rework the timekeeping data storage

   timekeeping accessors, which was good enough at the time when it was
   designed.

a50b4fe095 A treewide hrtimer timer cleanup 
hrtimers are initialized with hrtimer_init() and a subsequent store to
   the callback pointer. This turned out to be suboptimal for the upcoming
   Rust integration and is obviously a silly implementation to begin with.
 
   This cleanup replaces the hrtimer_init(T); T->function = cb; sequence
   with hrtimer_setup(T, cb);
 
   The conversion was done with Coccinelle and a few manual fixups.
 
   Once the conversion has completely landed in mainline, hrtimer_init()
   will be removed and the hrtimer::function becomes a private member.

d5048d1176 Updates for the core time/timer subsystem: 
- Fix a memory ordering issue in posix-timers
 
     Posix-timer lookup is lockless and reevaluates the timer validity under
     the timer lock, but the update which validates the timer is not
     protected by the timer lock. That allows the store to be reordered
     against the initialization stores, so that the lookup side can observe
     a partially initialized timer. That's mostly a theoretical problem, but
     incorrect nevertheless.
 
   - Fix a long standing inconsistency of the coarse time getters
 
     The coarse time getters read the base time of the current update cycle
     without reading the actual hardware clock. NTP frequency adjustment can
     set the base time backwards. The fine grained interfaces compensate
     this by reading the clock and applying the new conversion factor, but
     the coarse grained time getters use the base time directly. That allows
     the user to observe time going backwards.
 
     Cure it by always forwarding base time, when NTP changes the frequency
     with an immediate step.
 
   - Rework of posix-timer hashing
 
     The posix-timer hash is not scalable and due to the CRIU timer restore
     mechanism prone to massive contention on the global hash bucket lock.
 
     Replace the global hash lock with a fine grained per bucket locking
     scheme to address that.
 
   - Rework the proc/$PID/timers interface.
 
     /proc/$PID/timers is provided for CRIU to be able to restore a
     timer. The printout happens with sighand lock held and interrupts
     disabled. That's not required as this can be done with RCU protection
     as well.
 
   - Provide a sane mechanism for CRIU to restore a timer ID
 
     CRIU restores timers by creating and deleting them until the kernel
     internal per process ID counter reached the requested ID. That's
     horribly slow for sparse timer IDs.
 
     Provide a prctl() which allows CRIU to restore a timer with a given
     ID. When enabled the ID pointer is used as input pointer to read the
     requested ID from user space. When disabled, the normal allocation
     scheme (next ID) is active as before. This is backwards compatible for
     both kernel and user space.
 
   - Make hrtimer_update_function() less expensive.
 
     The sanity checks are valuable, but expensive for high frequency usage
     in io/uring. Make the debug checks conditional and enable them only
     when lockdep is enabled.
 
   - Small updates, cleanups and improvements

     Architecture.

     This moves the driver over to the generic MSI library and solves the
     affinity problem of unmaskable PCI/MSI controllers. Unmaskable PCI/MSI
     controllers are prone to lose interrupts when the MSI message is
     updated to change the affinity because the message write consists of
     three 32-bit subsequent writes, which update address and data. As these
     writes are non-atomic versus the device raising an interrupt, the
     device can observe a half written update and issue an interrupt on the
     wrong vector. This is mitiated by a carefully orchestrated step by step
     update and the observation of an eventually pending interrupt on the
     CPU which issues the update. The algorithm follows the well established
     method of the X86 MSI driver.
 
   - A new driver for the RISC-V Sophgo SG2042 MSI controller
 
   - Overhaul of the Renesas RZQ2L driver.
 
     Simplification of the probe function by using devm_*() mechanisms,
     which avoid the endless list of error prone gotos in the failure paths.

     physical address space.
 
   - Add support for the Allwinner AS23 NMI controller

   - The usual small updates, cleanups and device tree changes.

be8cd366be ALSA: hda/realtek: Bass speaker fixup for ASUS UM5606KA 
This patch applies the ALC294 bass speaker fixup (ALC294_FIXUP_BASS_SPEAKER_15),
previously introduced in commit a7df7f909c ("ALSA: hda: improve bass
speaker support for ASUS Zenbook UM5606WA"), to the ASUS Zenbook UM5606KA.
This hardware configuration matches ASUS Zenbook UM5606WA, where DAC NID
0x06 was removed from the bass speaker (NID 0x15), routing both speaker
pins to DAC NID 0x03.

This resolves the bass speaker routing issue, ensuring correct audio
output on ASUS UM5606KA.

2df0c02dab x86 boot build: make git ignore stale 'tools' directory 
We've had this before: when we remove infrastructure to generate files,
the old stale build artifacts still remain in-tree.  And when the
infrastructure to generate them is gone, so is the gitignore file for
those build artifacts.

End result: git will see the old generated files, and people will
mistakenly commit them.  That's what happened with the 'genheaders' file
not that long ago (see commit 04a3389b35 "Remove stale generated
'genheaders' file").

This time it's commit 9c54baab44 ("x86/boot: Drop CRC-32 checksum and
the build tool that generates it") that removed the 'build' file from
the arch/x86/boot/tools/ subdirectory, and removed the .gitignore file
too (because the whole subdirectory is gone).

And as a result, if you don't do a 'git clean -dqfx' or similar to clean
up your tree, 'git status' will say

  Untracked files:
    (use "git add <file>..." to include in what will be committed)
	arch/x86/boot/tools/

and some hapless sleep-deprived developer will inevitably decide that
that means that they need to 'git add' that directory.  Which would
bring back some stale generated file that we most definitely do not want
in the tree.

So when removing directories that had special .gitignore patterns, make
sure to add a new gitignore entry in the parent directory for the no
longer existing subdirectory.

It will avoid mistakes.
