If loading a core PMU fails, legacy hardware/cache events may segv due
to there being no PMU. Create a placeholder empty PMU for this
case. This was discussed in:

Pull hardening updates from Kees Cook:
"There are three areas of note:
A bunch of strlcpy()->strscpy() conversions ended up living in my tree
since they were either Acked by maintainers for me to carry, or got
ignored for multiple weeks (and were trivial changes).
The compiler option '-fstrict-flex-arrays=3' has been enabled
globally, and has been in -next for the entire devel cycle. This
changes compiler diagnostics (though mainly just -Warray-bounds which
is disabled) and potential UBSAN_BOUNDS and FORTIFY _warning_
coverage. In other words, there are no new restrictions, just
potentially new warnings. Any new FORTIFY warnings we've seen have
been fixed (usually in their respective subsystem trees). For more
details, see commit df8fc4e934c12b.
The under-development compiler attribute __counted_by has been added
so that we can start annotating flexible array members with their
associated structure member that tracks the count of flexible array
elements at run-time. It is possible (likely?) that the exact syntax
of the attribute will change before it is finalized, but GCC and Clang
are working together to sort it out. Any changes can be made to the
macro while we continue to add annotations.
As an example of that last case, I have a treewide commit waiting with
such annotations found via Coccinelle:
https://git.kernel.org/linus/adc5b3cb48a049563dc673f348eab7b6beba8a9b
Also see commit dd06e72e68bcb4 for more details.
Summary:
- Fix KMSAN vs FORTIFY in strlcpy/strlcat (Alexander Potapenko)
- Convert strreplace() to return string start (Andy Shevchenko)
- Flexible array conversions (Arnd Bergmann, Wyes Karny, Kees Cook)
- Add missing function prototypes seen with W=1 (Arnd Bergmann)
- Fix strscpy() kerndoc typo (Arne Welzel)
- Replace strlcpy() with strscpy() across many subsystems which were
either Acked by respective maintainers or were trivial changes that
went ignored for multiple weeks (Azeem Shaikh)
- Remove unneeded cc-option test for UBSAN_TRAP (Nick Desaulniers)
- Add KUnit tests for strcat()-family
- Enable KUnit tests of FORTIFY wrappers under UML
- Add more complete FORTIFY protections for strlcat()
- Add missed disabling of FORTIFY for all arch purgatories.
- Enable -fstrict-flex-arrays=3 globally
- Tightening UBSAN_BOUNDS when using GCC
- Improve checkpatch to check for strcpy, strncpy, and fake flex
arrays
- Improve use of const variables in FORTIFY
- Add requested struct_size_t() helper for types not pointers
- Add __counted_by macro for annotating flexible array size members"

Pull objtool updates from Ingo Molar:
"Build footprint & performance improvements:
- Reduce memory usage with CONFIG_DEBUG_INFO=y
In the worst case of an allyesconfig+CONFIG_DEBUG_INFO=y kernel,
DWARF creates almost 200 million relocations, ballooning objtool's
peak heap usage to 53GB. These patches reduce that to 25GB.
On a distro-type kernel with kernel IBT enabled, they reduce
objtool's peak heap usage from 4.2GB to 2.8GB.
These changes also improve the runtime significantly.
Debuggability improvements:
- Add the unwind_debug command-line option, for more extend unwinding
debugging output
- Limit unreachable warnings to once per function
- Add verbose option for disassembling affected functions
- Include backtrace in verbose mode
- Detect missing __noreturn annotations
- Ignore exc_double_fault() __noreturn warnings
- Remove superfluous global_noreturns entries
- Move noreturn function list to separate file
- Add __kunit_abort() to noreturns
Unwinder improvements:
- Allow stack operations in UNWIND_HINT_UNDEFINED regions
- drm/vmwgfx: Add unwind hints around RBP clobber
Cleanups:
- Move the x86 entry thunk restore code into thunk functions
- x86/unwind/orc: Use swap() instead of open coding it

The original logic was to check is_pmu_hybrid() like in the below.
It just checks the name of PMU specifically for Intel hybrid systems
which means uncore PMU events should return false.
https://lore.kernel.org/all/20230527072210.2900565-35-irogers@google.com/
The is_pmu_hybrid() was replaced by arch-agnostic way but with the
incorrect condition which was fixed for core PMUs but not uncore.
This change fixes both.

Pull RCU updates from Paul McKenney:
"Documentation updates
Miscellaneous fixes, perhaps most notably:
- Remove RCU_NONIDLE(). The new visibility of most of the idle loop
to RCU has obsoleted this API.
- Make the RCU_SOFTIRQ callback-invocation time limit also apply to
the rcuc kthreads that invoke callbacks for CONFIG_PREEMPT_RT.
- Add a jiffies-based callback-invocation time limit to handle
long-running callbacks. (The local_clock() function is only invoked
once per 32 callbacks due to its high overhead.)
- Stop rcu_tasks_invoke_cbs() from using never-onlined CPUs, which
fixes a bug that can occur on systems with non-contiguous CPU
numbering.
kvfree_rcu updates:
- Eliminate the single-argument variant of k[v]free_rcu() now that
all uses have been converted to k[v]free_rcu_mightsleep().
- Add WARN_ON_ONCE() checks for k[v]free_rcu*() freeing callbacks too
soon. Yes, this is closing the barn door after the horse has
escaped, but Murphy says that there will be more horses.

- Fix a number of bugs involving the shrinker and lazy callbacks.

Pull btrfs updates from David Sterba:
"Mainly core changes, refactoring and optimizations.
Performance is improved in some areas, overall there may be a
cumulative improvement due to refactoring that removed lookups in the
IO path or simplified IO submission tracking.
Core:
- submit IO synchronously for fast checksums (crc32c and xxhash),
remove high priority worker kthread
- read extent buffer in one go, simplify IO tracking, bio submission
and locking
- remove additional tracking of redirtied extent buffers, originally
added for zoned mode but actually not needed
- track ordered extent pointer in bio to avoid rbtree lookups during
IO
- scrub, use recovered data stripes as cache to avoid unnecessary
read
- in zoned mode, optimize logical to physical mappings of extents
- remove PageError handling, not set by VFS nor writeback
- cleanups, refactoring, better structure packing
- lots of error handling improvements
- more assertions, lockdep annotations
- print assertion failure with the exact line where it happens
- tracepoint updates
- more debugging prints
Performance:
- speedup in fsync(), better tracking of inode logged status can
avoid transaction commit
- IO path structures track logical offsets in data structures and
does not need to look it up
User visible changes:
- don't commit transaction for every created subvolume, this can
reduce time when many subvolumes are created in a batch
- print affected files when relocation fails
- trigger orphan file cleanup during START_SYNC ioctl
Notable fixes:
- fix crash when disabling quota and relocation
- fix crashes when removing roots from drity list
- fix transacion abort during relocation when converting from newer
profiles not covered by fallback
- in zoned mode, stop reclaiming block groups if filesystem becomes
read-only
- fix rare race condition in tree mod log rewind that can miss some
btree node slots
- with enabled fsverity, drop up-to-date page bit in case the
verification fails"

- Convert a lot of drivers to use maple tree based caches.
- Lots of work on the x86 driver stack.
- Compressed audio support for Qualcomm.
- Support for AMD SoundWire, Analog Devices SSM3515, Google Chameleon,
Ingenic X1000, Intel systems with various CODECs, Longsoon platforms,

Pick up the first half of the RCH error handling series. The back half
needs some fixups for test regressions. Small conflicts with the PMU
work around register enumeration and setup helpers.
|
|
Pick up initial support for the CXL 3.0 performance monitoring
definition. Small conflicts with the firmware update work as they both
placed their init code in the same location.
|
|
Pick up the driver cleanups identified in preparation for CXL "type-2"
(accelerator) device support. The major change here from a conflict
generation perspective is the split of 'struct cxl_memdev_state' from
the core 'struct cxl_dev_state'. Since an accelerator may not care about
all the optional features that are standard on a CXL "type-3" (host-only
memory expander) device.
A silent conflict also occurs with the move of the endpoint port to be a
formal property of a 'struct cxl_memdev' rather than drvdata.
|
|
Add the first typical (non-sanitization) consumer of the new background
command infrastructure, firmware update. Given both firmware-update and
sanitization were developed in parallel from the common
background-command baseline, resolve some minor context conflicts.
|
|
Pick up the sanitization work and the infrastructure for other
background commands for 6.5. Sanitization has a different completion
path than typical background commands so it was important to have both
thought out and implemented before either went upstream.
|
|
Add emulation for the 'Get FW Info', 'Transfer FW', and 'Activate FW'
CXL mailbox commands to the cxl_test emulated memdevs to enable
end-to-end unit testing of a firmware update flow. For now, only
advertise an 'offline activation' capability as that is all the CXL
memdev driver currently implements.
Add some canned values for the serial number fields, and create a
platform device sysfs knob to calculate the sha256sum of the firmware
image that was received, so a unit test can compare it with the original
file that was uploaded.

commit eb0764b822b9 ("cxl/port: Enable the HDM decoder capability for switch ports")
...was added on the observation of CXL memory not being accessible after
setting up a region on a "cold-plugged" device. A "cold-plugged" CXL
device is one that was not present at boot, so platform-firmware/BIOS
has no chance to set it up.
While it is true that the debug found the enable bit clear in the
host-bridge's instance of the global control register (CXL 3.0
8.2.4.19.2 CXL HDM Decoder Global Control Register), that bit is
described as:
"This bit is only applicable to CXL.mem devices and shall
return 0 on CXL Host Bridges and Upstream Switch Ports."
So it is meant to be zero, and further testing confirmed that this "fix"
had no effect on the failure. Revert it, and be more vigilant about
proposed fixes in the future. Since the original copied stable@, flag
this revert for stable@ as well.

'struct cxl_dev_state' makes too many assumptions about the capabilities
of a CXL device. In particular it assumes a CXL device has a mailbox and
all of the infrastructure and state that comes along with that.
In preparation for supporting accelerator / Type-2 devices that may not
have a mailbox and in general maintain a minimal core context structure,
make mailbox functionality a super-set of 'struct cxl_dev_state' with
'struct cxl_memdev_state'.
With this reorganization it allows for CXL devices that support HDM
decoder mapping, but not other general-expander / Type-3 capabilities,
to only enable that subset without the rest of the mailbox
infrastructure coming along for the ride.

Prepare cxl_probe_rcrb() for retrieving more than just the component
register block. The RCH AER handling code wants to get back to the AER
capability that happens to be MMIO mapped rather then configuration
cycles.
Move RCRB specific downstream port data, like the RCRB base and the
AER capability offset, into its own data structure ('struct
cxl_rcrb_info') for cxl_probe_rcrb() to fill. Extend 'struct
cxl_dport' to include a 'struct cxl_rcrb_info' attribute.
This centralizes all RCRB scanning in one routine.

The RCRB is extracted already during ACPI CEDT table parsing while the
data of this is needed not earlier than dport creation. This
implementation comes with drawbacks: During ACPI table scan there is
already MMIO access including mapping and unmapping, but only ACPI
data should be collected here. The collected data must be transferred
through a couple of interfaces until it is finally consumed when
creating the dport. This causes complex data structures and function
interfaces. Additionally, RCRB parsing will be extended to also
extract AER data, it would be much easier do this at a later point
during port and dport creation when the data structures are available
to hold that data.
To simplify all that, probe the RCRB at a later point during RCH
downstream port creation. Change ACPI table parser to only extract the
base address of either the component registers or the RCRB. Parse and
extract the RCRB in devm_cxl_add_rch_dport().
This is in preparation to centralize all RCRB scanning.
