66ffd2f316 Documentation: openrisc: Update toolchain binaries URL
The old development toolchain binaries were hosted in the or1k-gcc
development github repo release page.  However, now that we have all
code upstream I cut releases from stable upstream tarballs.  It does not
make sense to tag the or1k-gcc github repo releases for these stable
releases.

Update the toolchain binaries URL to point to where they are now hosted
on the or1k-toolchain-build github release page.

4e6d24a309 openrisc: Add cacheinfo support
Add cacheinfo support for OpenRISC.

Currently, a few CPU cache attributes pertaining to OpenRISC processors
are exposed along with other unrelated CPU attributes in the procfs file
system (/proc/cpuinfo). However, a few cache attributes remain unexposed.

Provide a mechanism that the generic cacheinfo infrastructure can employ
to expose these attributes via the sysfs file system. These attributes
can then be exposed in /sys/devices/system/cpu/cpuX/cache/indexN. Move
the implementation to pull cache attributes from the processor's
registers from arch/openrisc/kernel/setup.c with a few modifications.

This implementation is based on similar work done for MIPS and LoongArch.

0c4a6e79ef openrisc: Introduce new utility functions to flush and invalidate caches
According to the OpenRISC architecture manual, the dcache and icache may
not be present. When these caches are present, the invalidate and flush
registers may be absent. The current implementation does not perform
checks to verify their presence before utilizing cache registers, or
invalidating and flushing cache blocks.

Introduce new functions to detect the presence of cache components and
related special-purpose registers.

There are a few places where a range of addresses have to be flushed or
invalidated and the implementation is duplicated. Introduce new utility
functions and macros that generalize this implementation and reduce
duplication.

efabefb05a openrisc: Refactor struct cpuinfo_or1k to reduce duplication
The "cpuinfo_or1k" structure currently has identical data members for
different cache components.

Remove these fields out of struct cpuinfo_or1k and into its own struct.
This reduces duplication while keeping cpuinfo_or1k extensible so more
cache descriptors can be added in the future.

Also add a new field "sets" to the new structure.

Pull vfs fixes from Christian Brauner:

 - Revert the hfs{plus} deprecation warning that's also included in this
   pull request. The commit introducing the deprecation warning resides
   rather early in this branch. So simply dropping it would've rebased
   all other commits which I decided to avoid. Hence the revert in the
   same branch

   [ Background - the deprecation warning discussion resulted in people
     stepping up, and so hfs{plus} will have a maintainer taking care of
     it after all..   - Linus ]

 - Switch CONFIG_SYSFS_SYCALL default to n and decouple from
   CONFIG_EXPERT

 - Fix an audit bug caused by changes to our kernel path lookup helpers
   this cycle. Audit needs the parent path even if the dentry it tried
   to look up is negative

 - Ensure that the kernel path lookup helpers leave the passed in path
   argument clean when they return an error. This is consistent with all
   our other helpers

 - Ensure that vfs_getattr_nosec() calls bdev_statx() so the relevant
   information is available to kernel consumers as well

 - Don't set a timer and call schedule() if the timer will expire
   immediately in epoll

 - Make netfs lookup tables with __nonstring

fa6ad96dca tracing fixes for v6.15
- Initialize hash variables in ftrace subops logic
 
   The fix that simplified the ftrace subops logic opened a path where some
   variables could be used without being initialized, and done subtly where
   the compiler did not catch it. Initialize those variables to the
   EMPTY_HASH, which is the default hash.
 
 - Reinitialize the hash pointers after they are freed
 
   Some of the hash pointers in the subop logic were freed but may still be
   referenced later. To prevent use-after-free bugs, initialize them back to
   the EMPTY_HASH.
 
 - Free the ftrace hashes when they are replaced
 
   The fix that simplified the subops logic updated some hash pointers, but
   left the original hash that they were pointing to where they are no longer
   used. This caused a memory leak. Free the hashes that are pointed to by
   the pointers when they are replaced.
 
 - Fix size initialization of ftrace direct function hash
 
   The ftrace direct function hash used by BPF initialized the hash size
   incorrectly. It checked the size of items to a hard coded 32, which made
   the hash bit size of 5. The hash size is supposed to be limited by the bit
   size of the hash, as the bitmask is allowed to be greater than 5. Rework
   the size check to first pass the number of elements to fls() and then
   compare that to FTRACE_HASH_MAX_BITS before allocating the hash.
 
 - Fix format output of ftrace_graph_ent_entry event
 
   The field depth of the ftrace_graph_ent_entry event is of size 4 but the
   output showed it as unsigned long and use "%lu". Change it to unsigned int
   and use "%u" in the print format that is displayed to user space.
 
 - Fix the trace event filter on strings
 
   Events can be filtered on numbers or string values. The return value
   checked from strncpy_from_kernel_nofault() and strncpy_from_user_nofault()
   was used to determine if reading the strings would fault or not. It would
   return fault if the value was non zero, which is basically meant that it
   was always considering the read as a fault.
 
 - Add selftest to test trace event string filtering
 
   In order to catch the breakage of the string filtering, add a self test to
   make sure that it continues to work.

83b2d345e1 x86/e820: Discard high memory that can't be addressed by 32-bit systems
Dave Hansen reports the following crash on a 32-bit system with
CONFIG_HIGHMEM=y and CONFIG_X86_PAE=y:

  > 0xf75fe000 is the mem_map[] entry for the first page >4GB. It
  > obviously wasn't allocated, thus the oops.

The mem_map[] is allocated up to the end of ZONE_HIGHMEM which is defined
by max_pfn.

The bug was introduced by this recent commit:

  6faea3422e ("arch, mm: streamline HIGHMEM freeing")

Previously, freeing of high memory was also clamped to the end of
ZONE_HIGHMEM but after this change, memblock_free_all() tries to
free memory above the of ZONE_HIGHMEM as well and that causes
access to mem_map[] entries beyond the end of the memory map.

To fix this, discard the memory after max_pfn from memblock on
32-bit systems so that core MM would be aware only of actually
usable memory.

IB_SIZE is only b0..b19.  Starting with a6xx gen3, additional fields
were added above the IB_SIZE.  Accidentially setting them can cause
badness.  Fix this by properly defining the CP_INDIRECT_BUFFER packet
and using the generated builder macro to ensure unintended bits are not
set.

0747c13675 MAINTAINERS: Move Manivannan Sadhasivam as PCI Native host bridge and endpoint maintainer
I'm currently maintaining the PCI endpoint subsystem and reviewing the
native host bridge and endpoint drivers. However, this affects my endpoint
maintainership role since I cannot merge endpoint patches that depend on
the controller drivers (which is more common). Moreover, the controller
driver patches would also benefit from a helping hand in maintaining them.

So I'd like to step up to maintain the native host bridge and endpoint
drivers together with the endpoint subsystem.

117c3b21d3 arm64: Rework checks for broken Cavium HW in the PI code
Calling into the MIDR checking framework from the PI code has recently
become much harder, due to the new fancy "multi-MIDR" support that
relies on tables being populated at boot time, but not that early that
they are available to the PI code. There are additional issues with
this framework, as the code really isn't position independend *at all*.

This leads to some ugly breakages, as reported by Ada.

It so appears that the only reason for the PI code to call into the
MIDR checking code is to cope with The Most Broken ARM64 System Ever,
aka Cavium ThunderX, which cannot deal with nG attributes that result
of the combination of KASLR and KPTI as a consequence of Erratum 27456.

Duplicate the check for the erratum in the PI code, removing the
dependency on the bulk of the MIDR checking framework. This allows
dropping that same check from kaslr_requires_kpti(), as the KPTI code
already relies on the ARM64_WORKAROUND_CAVIUM_27456 cap.

25174d5cd2 cxl/feature: Update out_len in set feature failure case
CXL subsystem supports userspace to configure features via fwctl
interface, it will configure features by using Set Feature command.
Whatever Set Feature succeeds or fails, CXL driver always needs to
return a structure fwctl_rpc_cxl_out to caller, and returned size is
updated in a out_len parameter. The out_len should be updated not only
when the set feature succeeds, but also when the set feature fails.

dc915672f9 cxl: Fix devm host device for CXL fwctl initialization
Testing revealed the following error message for a CXL memdev that has
Feature support:
[   56.690430] cxl mem0: Resources present before probing

Attach the allocation of cxl_fwctl to the parent device of cxl_memdev.
devm_add_* calls for cxl_memdev should not happen before the memdev
probe function or outside the scope of the memdev driver.

cxl_test missed this bug because cxl_test always arranges for the
cxl_mem driver to be loaded before cxl_mock_mem runs. So the driver core
always finds the devres list idle in that case.

   Three cleanups to make it saner first, then two fixes for each of the

   This fixes a performance regression where partial buffer usage
   doesn't trim the tail number of segments, leading the block layer to
   iterate the IOs to check if it needs splitting.

d481ee3524 tracing: selftests: Add testing a user string to filters
Running the following commands was broken:

  # echo 1 > events/syscalls/sys_enter_openat/enable
  # ls /proc/$$/maps
  # cat trace

And would produce nothing when it should have produced something like:

Add a test to check this case so that it will be caught if it breaks
again.

f591cf9fce vhost-scsi: protect vq->log_used with vq->mutex
The vhost-scsi completion path may access vq->log_base when vq->log_used is

                                      mutex_lock(&vq->mutex);
                                      vq->log_used = false now!

				      QEMU gfree(vq->log_base)
        log_used()

Assuming the VMM is QEMU. The vq->log_base is from QEMU userpace and can be
reclaimed via gfree(). As a result, this causes invalid memory writes to
QEMU userspace.

The control queue path has the same issue.

spec(version 1.2) a control buffer with the event VIRTIO_CONSOLE_RESIZE
is followed by a virtio_console_resize struct containing cols then rows.
The kernel implements this the wrong way around (rows then cols) resulting
in the two values being swapped.

fbd3039a64 virtio_console: fix missing byte order handling for cols and rows
As per virtio spec the fields cols and rows are specified as little
endian. Although there is no legacy interface requirement that would
state that cols and rows need to be handled as native endian when legacy
interface is used, unlike for the fields of the adjacent struct
virtio_console_control, I decided to err on the side of caution based
on some non-conclusive virtio spec repo archaeology and opt for using
virtio16_to_cpu() much like for virtio_console_control.event. Strictly
by the letter of the spec virtio_le_to_cpu() would have been sufficient.
But when the legacy interface is not used, it boils down to the same.

And when using the legacy interface, the device formatting these as
little endian when the guest is big endian would surprise me more than
it using guest native byte order (which would make it compatible with
the current implementation). Nevertheless somebody trying to implement
the spec following it to the letter could end up forcing little endian
byte order when the legacy interface is in use. So IMHO this ultimately
needs a judgement call by the maintainers.

It looks like the shutdown is called in the middle of console drawing, so
we should either wait for it to finish, or let drm handle the shutdown.

This patch implements this second option:

Add an option for drivers to bypass the common break+reset handling.
As DRM is careful to flush/synchronize outstanding buffers, it looks like
GPU can just have a NOP there.

39e703ed3b selftests/pcie_bwctrl: Fix test progs list
Commit df6f8c4d72 ("selftests/pcie_bwctrl: Add 'set_pcie_speed.sh' to
TEST_PROGS") added set_pcie_speed.sh into TEST_PROGS but that script is a
helper that is only being called by set_pcie_cooling_state.sh, not a test
case itself. When set_pcie_speed.sh is in TEST_PROGS, selftest harness will
execute also it leading to bwctrl selftest errors:

  # selftests: pcie_bwctrl: set_pcie_speed.sh
  # cat: /cur_state: No such file or directory
  not ok 2 selftests: pcie_bwctrl: set_pcie_speed.sh # exit=1

Place set_pcie_speed.sh into TEST_FILES instead to have it included into
installed test files but not execute it from the test harness.

a34d74877c PCI: Restore assigned resources fully after release
PCI resource fitting code in __assign_resources_sorted() runs in multiple
steps. A resource that was successfully assigned may have to be released
before the next step attempts assignment again. The assign+release cycle is
destructive to a start-aligned struct resource (bridge window or IOV
resource) because the start field is overwritten with the real address when
the resource got assigned.

One symptom:

  pci 0002:00:00.0: bridge window [mem size 0x00100000]: can't assign; bogus alignment

Properly restore the resource after releasing it. The start, end, and flags
fields must be stored into the related struct pci_dev_resource in order to
be able to restore the resource to its original state.

Fixes: 96336ec702 ("PCI: Perform reset_resource() and build fail list in sync")
