fd2dee1c6e ARM: fix branch predictor hardening 
__do_user_fault() may be called with indeterminent interrupt enable
state, which means we may be preemptive at this point. This causes
problems when calling harden_branch_predictor(). For example, when
called from a data abort, do_alignment_fault()->do_bad_area().

Move harden_branch_predictor() out of __do_user_fault() and into the
calling contexts.

Moving it into do_kernel_address_page_fault(), we can be sure that
interrupts will be disabled here.

Converting do_translation_fault() to use do_kernel_address_page_fault()
rather than do_bad_area() means that we keep branch predictor handling
for translation faults. Interrupts will also be disabled at this call
site.

do_sect_fault() needs special handling, so detect user mode accesses
to kernel-addresses, and add an explicit call to branch predictor
hardening.

Finally, add branch predictor hardening to do_alignment() for the
faulting case (user mode accessing kernel addresses) before interrupts
are enabled.

This should cover all cases where harden_branch_predictor() is called,
ensuring that it is always has interrupts disabled, also ensuring that
it is called early in each call path.

7733bc7d29 ARM: fix hash_name() fault 
Zizhi Wo reports:

"During the execution of hash_name()->load_unaligned_zeropad(), a
 potential memory access beyond the PAGE boundary may occur. For
 example, when the filename length is near the PAGE_SIZE boundary.
 This triggers a page fault, which leads to a call to
 do_page_fault()->mmap_read_trylock(). If we can't acquire the lock,
 we have to fall back to the mmap_read_lock() path, which calls
 might_sleep(). This breaks RCU semantics because path lookup occurs
 under an RCU read-side critical section."

This is seen with CONFIG_DEBUG_ATOMIC_SLEEP=y and CONFIG_KFENCE=y.

Kernel addresses (with the exception of the vectors/kuser helper
page) do not have VMAs associated with them. If the vectors/kuser
helper page faults, then there are two possibilities:

1. if the fault happened while in kernel mode, then we're basically
   dead, because the CPU won't be able to vector through this page
   to handle the fault.
2. if the fault happened while in user mode, that means the page was
   protected from user access, and we want to fault anyway.

Thus, we can handle kernel addresses from any context entirely
separately without going anywhere near the mmap lock. This gives us
an entirely non-sleeping path for all kernel mode kernel address
faults.

As we handle the kernel address faults before interrupts are enabled,
this change has the side effect of improving the branch predictor
hardening, but does not completely solve the issue.

40b466db1d ARM: allow __do_kernel_fault() to report execution of memory faults 
Allow __do_kernel_fault() to detect the execution of memory, so we can
provide the same fault message as do_page_fault() would do. This is
required when we split the kernel address fault handling from the
main do_page_fault() code path.

   and errors out, failing the build.

7a7e836684 tracing: Fix unused tracepoints when module uses only exported ones 
Building the KVM intel module failed to build with UT=1:

no __tracepoint_strings in file: arch/x86/kvm/kvm-intel.o
make[3]: *** [/work/git/test-linux.git/scripts/Makefile.modfinal:62: arch/x86/kvm/kvm-intel.ko] Error 1

The reason is that the module only uses the tracepoints defined and
exported by the main kvm module. The tracepoint-update.c code fails the
build if a tracepoint is used, but there's no tracepoints defined. But
this is acceptable in modules if the tracepoints are defined in the vmlinux
proper or another module and exported.

Do not fail to build if a tracepoint is used but no tracepoints are
defined if the code is a module. This should still never happen for the
vmlinux itself.

12eef14bcb lockref: add a __cond_lock annotation for lockref_put_or_lock 
Add a cond_lock annotation for lockref_put_or_lock to make sparse
happy with using it.  Note that for this the return value has to be
double-inverted as the return value convention of lockref_put_or_lock
is inverted compared to _trylock conventions expected by __cond_lock,
as lockref_put_or_lock returns true when it did not need to take the
lock.

dea20281ac ARM: group is_permission_fault() with is_translation_fault() 
Group is_permission_fault() with is_translation_fault(), which is
needed to use is_permission_fault() in __do_kernel_fault(). As
this is static inline, there is no need for this to be under
CONFIG_MMU.

edb924a721 ARM: 9464/1: fix input-only operand modification in load_unaligned_zeropad() 
In the inline assembly inside load_unaligned_zeropad(), the "addr" is
constrained as input-only operand. The compiler assumes that on exit
from the asm statement these operands contain the same values as they
had before executing the statement, but when kernel page fault happened, the assembly fixup code "bic %2 %2, #0x3" modify the value of "addr", which may lead to an unexpected behavior.

Use a temporary variable "tmp" to handle it, instead of modifying the
input-only operand, just like what arm64's load_unaligned_zeropad()
does.

Fixes: b9a50f7490 ("ARM: 7450/1: dcache: select DCACHE_WORD_ACCESS for little-endian ARMv6+ CPUs")

cb015814f8 f2fs-for-6.19-rc1 
This series focuses on minor clean-ups and performance optimizations across
 sysfs, documentation, debugfs, tracepoints, slab allocation, and GC.
 Furthermore, it resolves several corner-case bugs caught by xfstests, as
 well as issues related to 16KB page support and f2fs_enable_checkpoint.
 
 Enhancement:
  - wrap ASCII tables in literal blocks to fix LaTeX build
  - optimize trace_f2fs_write_checkpoint with enums
  - support to show curseg.next_blkoff in debugfs
  - add a sysfs entry to show max open zones
  - add fadvise tracepoint
  - use global inline_xattr_slab instead of per-sb slab cache
  - set default valid_thresh_ratio to 80 for zoned devices
  - maintain one time GC mode is enabled during whole zoned GC cycle
 
 Bug fix:
  - ensure node page reads complete before f2fs_put_super() finishes
  - fix to not account invalid blocks in get_left_section_blocks()
  - revert summary entry count from 2048 to 512 in 16kb block support
  - fix to detect recoverable inode during dryrun of find_fsync_dnodes()
  - fix age extent cache insertion skip on counter overflow
  - Add sanity checks before unlinking and loading inodes
  - ensure minimum trim granularity accounts for all devices
  - block cache/dio write during f2fs_enable_checkpoint()
  - fix to propagate error from f2fs_enable_checkpoint()
  - invalidate dentry cache on failed whiteout creation
  - fix to avoid updating compression context during writeback
  - fix to avoid updating zero-sized extent in extent cache
  - fix to avoid potential deadlock

   - Use READ_ONCE/WRITE_ONCE consistently for ring mapped kbufs. Mostly
     for documentation purposes, indicating that they are shared with
     userspace

   - Fix for POLL_ADD losing a completion, if the request is updated and
     now is triggerable - eg, if POLLIN is set with the updated, and the
     polled file is readable

   - In conjunction with the above fix, also unify how poll wait queue
     entries are deleted with the head update. We had 3 different spots
     doing both the list deletion and head write, with one of them
     nicely documented. Abstract that into a helper and use it
     consistently

2fb6915fa2 compiler_types.h: add "auto" as a macro for "__auto_type" 
"auto" was defined as a keyword back in the K&R days, but as a storage
type specifier.  No one ever used it, since it was and is the default
storage type for local variables.

C++11 recycled the keyword to allow a type to be declared based on the
type of an initializer.  This was finally adopted into standard C in
C23.

gcc and clang provide the "__auto_type" alias keyword as an extension
for pre-C23, however, there is no reason to pollute the bulk of the
source base with this temporary keyword; instead define "auto" as a
macro unless the compiler is running in C23+ mode.

This macro is added in <linux/compiler_types.h> because that header is
included in some of the tools headers, wheres <linux/compiler.h> is
not as it has a bunch of very kernel-specific things in it.

9aeed90419 alpha: don't reference obsolete termio struct for TC* constants 
Similar in nature to ab10727660. glibc-2.42
drops the legacy termio struct, but the ioctls.h header still defines some
TC* constants in terms of termio (via sizeof). Hardcode the values instead.

This fixes building Python for example, which falls over like:
  ./Modules/termios.c:1119:16: error: invalid application of 'sizeof' to incomplete type 'struct termio'

3cec82b4fc alpha: Replace __ASSEMBLY__ with __ASSEMBLER__ in the alpha headers 
While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a
macro that only gets defined by the Makefiles in the kernel.
This can be very confusing when switching between userspace
and kernelspace coding, or when dealing with uapi headers that
rather should use __ASSEMBLER__ instead. So let's standardize now
on the __ASSEMBLER__ macro that is provided by the compilers.

This is a completely mechanical patch (done with a simple "sed -i"
statement).

a110f94267 Pin control changes for the v6.19 kernel cycle: 
Core changes:
 
 - Handle per-direction skew control in the generic pin config.
 
 - Drop the pointless subsystem boilerplate banner message during
   boot. Less noise in the console. It's available as debug message
   if someone really want it.
 
 New drivers:
 
 - Samsung Exynos 8890 SoC support.
 
 - Samsung Exynos derived Axis Communications ARTPEC-9 SoC support.
   These guys literally live next door to me, ARTPEC spells out
   "Axis Real-Time Picture Encoding Chip" and is tailored for camera
   image streams and is something they have evolved for a quarter of
   a century.
 
 - Mediatek MT6878 SoC support.
 
 - Qualcomm Glymur PMIC support (mostly just compatible strings).
 
 - Qualcomm Kaanapali SoC TLMM support.
 
 - Microchip pic64gx "gpio2" SoC support.
 
 - Microchip Polarfire "iomux0" SoC support.
 
 - CIX Semiconductors SKY1 SoC support.
 
 - Rockchip RK3506 SoC support.
 
 - Airhoa AN7583 chip support.
 
 Improvements:
 
 - Improvements for ST Microelectronics STM32 handling of skew
   settings so input and output can have different skew settings.
 
 - A whole bunch of device tree binding cleanups: Marvell Armada and
   Berlin, Actions Semiconductor S700 and S900, Broadcom Northstar 2
   (NS2), Bitmain BM1880 and Spreadtrum SC9860 are moved over to schema.

70075e3d0c s390/bug: Add missing alignment 
All objects are supposed to have a minimal alignment of two, since a
couple of instructions only work with even addresses. Add the missing
align statement for the file string.

1a82d430c5 s390/bug: Add missing CONFIG_BUG ifdef again 
Fallback to generic BUG implementation in case CONFIG_BUG is disabled.
This restores the old behaviour before 'cond_str' support was added.

It probably doesn't matter, since nobody should disable CONFIG_BUG, but at
least this is consistent to before.

31b931bebd dma-mapping: Fix DMA_BIT_MASK() macro being broken 
After commit a50f7456f8 ("dma-mapping: Allow use of DMA_BIT_MASK(64) in
global scope"), the DMA_BIT_MASK() macro is broken when passed non trivial
statements for the value of 'n'. This is caused by the new version missing
parenthesis around 'n' when evaluating 'n'.

One example of this breakage is the IPU6 driver now crashing due to
it getting DMA-addresses with address bit 32 set even though it has
tried to set a 32 bit DMA mask.

The IPU6 CSI2 engine has a DMA mask of either 31 or 32 bits depending
on if it is in secure mode or not and it sets this masks like this:

        mmu_info->aperture_end =
                (dma_addr_t)DMA_BIT_MASK(isp->secure_mode ?
                                         IPU6_MMU_ADDR_BITS :
                                         IPU6_MMU_ADDR_BITS_NON_SECURE);

So the 'n' argument here is "isp->secure_mode ? IPU6_MMU_ADDR_BITS :
IPU6_MMU_ADDR_BITS_NON_SECURE" which gets expanded into:

isp->secure_mode ? IPU6_MMU_ADDR_BITS : IPU6_MMU_ADDR_BITS_NON_SECURE - 1

With the -1 only being applied in the non secure case, causing
the secure mode mask to be one 1 bit too large.
