There are two menu entries for X86_EXTENDED_PLATFORM, one for X86_32 and
the other for X86_64.
These entries are nearly identical, with the only difference being the
platform list in the help message.
While this structure was intended by commit
8425091ff8af ("x86: improve the help text of X86_EXTENDED_PLATFORM"),
there is no need to duplicate the entire config entry. Instead, provide
a little more clarification in the help message.

discard_new_inode() is the wrong interface to use when we need to free
an inode that was never inserted into the inode hash table; we can
bypass the whole iput() -> evict() path and replace it with
__destroy_inode(); kmem_cache_free() - this fixes a WARN_ON() about
I_NEW.

bch2_journal_write() was incorrectly waiting on earlier journal writes
synchronously; this usually worked because most of the time we'd be
running in the context of a thread that did a journal_buf_put(), but
sometimes we'd be running out of the same workqueue that completes those
prior journal writes.
Additionally, this makes sure to punt to a workqueue before submitting
preflushes - we really don't want to be calling submit_bio() in the main
transaction commit path.

Freeing key cache items is a multi stage process; we need to wait for an
SRCU grace period to elapse, and we handle this ourselves - partially to
avoid callback overhead, but primarily so that when allocating we can
first allocate from the freed items waiting for an SRCU grace period.
Previously, the shrinker was counting the items on the 'waiting for SRCU
grace period' lists as items being scanned, but this meant that too many
items waiting for an SRCU grace period could prevent it from doing any
work at all.
After this, we're seeing that items skipped due to the accessed bit are
the main cause of the shrinker not making any progress, and we actually
want the key cache shrinker to run quite aggressively because reclaimed
items will still generally be found (more compactly) in the btree node
cache - so we also tweak the shrinker to not count those against
nr_to_scan.

Pull kvm fixes from Paolo Bonzini:
"This is a bit on the large side, mostly due to two changes:
- Changes to disable some broken PMU virtualization (see below for
details under "x86 PMU")
- Clean up SVM's enter/exit assembly code so that it can be compiled
without OBJECT_FILES_NON_STANDARD. This fixes a warning "Unpatched
return thunk in use. This should not happen!" when running KVM
selftests.
Everything else is small bugfixes and selftest changes:
- Fix a mostly benign bug in the gfn_to_pfn_cache infrastructure
where KVM would allow userspace to refresh the cache with a bogus
GPA. The bug has existed for quite some time, but was exposed by a
new sanity check added in 6.9 (to ensure a cache is either
GPA-based or HVA-based).
- Drop an unused param from gfn_to_pfn_cache_invalidate_start() that
got left behind during a 6.9 cleanup.
- Fix a math goof in x86's hugepage logic for
KVM_SET_MEMORY_ATTRIBUTES that results in an array overflow
(detected by KASAN).
- Fix a bug where KVM incorrectly clears root_role.direct when
userspace sets guest CPUID.
- Fix a dirty logging bug in the where KVM fails to write-protect
SPTEs used by a nested guest, if KVM is using Page-Modification
Logging and the nested hypervisor is NOT using EPT.
x86 PMU:
- Drop support for virtualizing adaptive PEBS, as KVM's
implementation is architecturally broken without an obvious/easy
path forward, and because exposing adaptive PEBS can leak host LBRs
to the guest, i.e. can leak host kernel addresses to the guest.
- Set the enable bits for general purpose counters in
PERF_GLOBAL_CTRL at RESET time, as done by both Intel and AMD
processors.
- Disable LBR virtualization on CPUs that don't support LBR
callstacks, as KVM unconditionally uses
PERF_SAMPLE_BRANCH_CALL_STACK when creating the perf event, and
would fail on such CPUs.
Tests:
- Fix a flaw in the max_guest_memory selftest that results in it
exhausting the supply of ucall structures when run with more than
256 vCPUs.
- Mark KVM_MEM_READONLY as supported for RISC-V in
set_memory_region_test"

There are two issues with SDHC2 configuration for SA8155P-ADP,
which prevent use of SDHC2 and causes issues with ethernet:
- Card Detect pin for SHDC2 on SA8155P-ADP is connected to gpio4 of
PMM8155AU_1, not to SoC itself. SoC's gpio4 is used for DWMAC
TX. If sdhc driver probes after dwmac driver, it reconfigures
gpio4 and this breaks Ethernet MAC.
- pinctrl configuration mentions gpio96 as CD pin. It seems it was
copied from some SM8150 example, because as mentioned above,
correct CD pin is gpio4 on PMM8155AU_1.
This patch fixes both mentioned issues by providing correct pin handle
and pinctrl configuration.

"A couple clk driver fixes, a build fix, and a deadlock fix:
- Mediatek mt7988 has broken PCIe because the wrong parent is used
- Mediatek clk drivers may deadlock when registering their clks
because the clk provider device is repeatedly runtime PM resumed
and suspended during probe and clk registration.
Resuming the clk provider device deadlocks with an ABBA deadlock
due to genpd_lock and the clk prepare_lock. The fix is to keep the
device runtime resumed while registering clks.
- Another runtime PM related deadlock, this time with disabling
unused clks during late init.
We get an ABBA deadlock where a device is runtime PM resuming (or
suspending) while the disabling of unused clks is happening in
parallel. That runtime PM action calls into the clk framework and
tries to grab the clk prepare_lock while the disabling of unused
clks holds the prepare_lock and is waiting for that runtime PM
action to complete.
The fix is to runtime resume all the clk provider devices before
grabbing the clk prepare_lock during disable unused.

On x86, the ordinary, position dependent small and kernel code models
only support placement of the executable in 32-bit addressable memory,
due to the use of 32-bit signed immediates to generate references to
global variables. For the kernel, this implies that all global variables
must reside in the top 2 GiB of the kernel virtual address space, where
the implicit address bits 63:32 are equal to sign bit 31.
This means the kernel code model is not suitable for other bare metal
executables such as the kexec purgatory, which can be placed arbitrarily
in the physical address space, where its address may no longer be
representable as a sign extended 32-bit quantity. For this reason,
commit
e16c2983fba0 ("x86/purgatory: Change compiler flags from -mcmodel=kernel to -mcmodel=large to fix kexec relocation errors")
switched to the large code model, which uses 64-bit immediates for all
symbol references, including function calls, in order to avoid relying
on any assumptions regarding proximity of symbols in the final
executable.
The large code model is rarely used, clunky and the least likely to
operate in a similar fashion when comparing GCC and Clang, so it is best
avoided. This is especially true now that Clang 18 has started to emit
executable code in two separate sections (.text and .ltext), which
triggers an issue in the kexec loading code at runtime.
The SUSE bugzilla fixes tag points to gcc 13 having issues with the
large model too and that perhaps the large model should simply not be
used at all.
Instead, use the position independent small code model, which makes no
assumptions about placement but only about proximity, where all
referenced symbols must be within -/+ 2 GiB, i.e., in range for a
RIP-relative reference. Use hidden visibility to suppress the use of a
GOT, which carries absolute addresses that are not covered by static ELF
relocations, and is therefore incompatible with the kexec loader's
relocation logic.

Performance regression reported with NFS/RDMA using Omnipath,
bisected to commit e084ee673c77 ("svcrdma: Add Write chunk WRs to
the RPC's Send WR chain").
Tracing on the server reports:
nfsd-7771 [060] 1758.891809: svcrdma_sq_post_err:
cq.id=205 cid=226 sc_sq_avail=13643/851 status=-12
sq_post_err reports ENOMEM, and the rdma->sc_sq_avail (13643) is
larger than rdma->sc_sq_depth (851). The number of available Send
Queue entries is always supposed to be smaller than the Send Queue
depth. That seems like a Send Queue accounting bug in svcrdma.
As it's getting to be late in the 6.9-rc cycle, revert this commit.
It can be revisited in a subsequent kernel release.

Fix a missing bounds check in superblock validation.
Note that we don't yet have repair code for this case - repair code for
individual items is generally low priority, since the whole superblock
is checksummed, validated prior to write, and we have backups.

====================
mlxsw: Fixes
This patchset fixes the following issues:
- During driver de-initialization the driver unregisters the EMAD
response trap by setting its action to DISCARD. However the manual
only permits TRAP and FORWARD, and future firmware versions will
enforce this.
In patch #1, suppress the error message by aligning the driver to the
manual and use a FORWARD (NOP) action when unregistering the trap.
- The driver queries the Management Capabilities Mask (MCAM) register
during initialization to understand if certain features are supported.
However, not all firmware versions support this register, leading to
the driver failing to load.
Patches #2 and #3 fix this issue by treating an error in the register
query as an indication that the feature is not supported.
v2:
- Patch #2:
- Make mlxsw_env_max_module_eeprom_len_query() void

The device's manual (PRM - Programmer's Reference Manual) classifies the
trap that is used to deliver EMAD responses as an "event trap". Among
other things, it means that the only actions that can be associated with
the trap are TRAP and FORWARD (NOP).
Currently, during driver de-initialization the driver unregisters the
trap by setting its action to DISCARD, which violates the above
guideline. Future firmware versions will prevent such misuses by
returning an error. This does not prevent the driver from working, but
an error will be printed to the kernel log during module removal /
devlink reload:
mlxsw_spectrum 0000:03:00.0: Reg cmd access status failed (status=7(bad parameter))
mlxsw_spectrum 0000:03:00.0: Reg cmd access failed (reg_id=7003(hpkt),type=write)
Suppress the error message by aligning the driver to the manual and use
a FORWARD (NOP) action when unregistering the trap.

When bringing down the TX rings we flush the rings but forget to
reclaimed the flushed packets. This leads to a memory leak since we
do not free the dma mapped buffers. This also leads to tx control
