pinctrl: qcom: switch to devm_register_sys_off_handler()
Error-handling paths in msm_pinctrl_probe() don't call
a function required to unroll restart handler registration,
unregister_restart_handler(). Instead of adding calls to this function,
switch the msm pinctrl code into using devm_register_sys_off_handler().
Fixes:

ARM:
* Avoid use of uninitialized memcache pointer in user_mem_abort()
* Always set HCR_EL2.xMO bits when running in VHE, allowing interrupts
to be taken while TGE=0 and fixing an ugly bug on AmpereOne that
occurs when taking an interrupt while clearing the xMO bits
(AC03_CPU_36)
* Prevent VMMs from hiding support for AArch64 at any EL virtualized by
KVM
* Save/restore the host value for HCRX_EL2 instead of restoring an
incorrect fixed value
* Make host_stage2_set_owner_locked() check that the entire requested
range is memory rather than just the first page
RISC-V:
* Add missing reset of smstateen CSRs
x86:
* Forcibly leave SMM on SHUTDOWN interception on AMD CPUs to avoid causing
problems due to KVM stuffing INIT on SHUTDOWN (KVM needs to sanitize the
VMCB as its state is undefined after SHUTDOWN, emulating INIT is the
least awful choice).
* Track the valid sync/dirty fields in kvm_run as a u64 to ensure KVM
KVM doesn't goof a sanity check in the future.
* Free obsolete roots when (re)loading the MMU to fix a bug where
pre-faulting memory can get stuck due to always encountering a stale
root.
* When dumping GHCB state, use KVM's snapshot instead of the raw GHCB page
to print state, so that KVM doesn't print stale/wrong information.
* When changing memory attributes (e.g. shared <=> private), add potential
hugepage ranges to the mmu_invalidate_range_{start,end} set so that KVM
doesn't create a shared/private hugepage when the the corresponding
attributes will become mixed (the attributes are commited *after* KVM
finishes the invalidation).
* Rework the SRSO mitigation to enable BP_SPEC_REDUCE only when KVM has at
least one active VM. Effectively BP_SPEC_REDUCE when KVM is loaded led
to very measurable performance regressions for non-KVM workloads.

Input: xpad - fix Share button on Xbox One controllers
The Share button, if present, is always one of two offsets from the end of the file, depending on the presence of a specific interface. As we lack parsing for the identify packet we can't automatically determine the presence of that interface, but we can hardcode which of these offsets is correct for a given controller. More controllers are probably fixable by adding the MAP_SHARE_BUTTON in the future, but for now I only added the ones that I have the ability to test directly.

KVM x86 fixes for 6.15-rcN
- Forcibly leave SMM on SHUTDOWN interception on AMD CPUs to avoid causing
problems due to KVM stuffing INIT on SHUTDOWN (KVM needs to sanitize the
VMCB as its state is undefined after SHUTDOWN, emulating INIT is the
least awful choice).
- Track the valid sync/dirty fields in kvm_run as a u64 to ensure KVM
KVM doesn't goof a sanity check in the future.
- Free obsolete roots when (re)loading the MMU to fix a bug where
pre-faulting memory can get stuck due to always encountering a stale
root.
- When dumping GHCB state, use KVM's snapshot instead of the raw GHCB page
to print state, so that KVM doesn't print stale/wrong information.
- When changing memory attributes (e.g. shared <=> private), add potential
hugepage ranges to the mmu_invalidate_range_{start,end} set so that KVM
doesn't create a shared/private hugepage when the the corresponding
attributes will become mixed (the attributes are commited *after* KVM
finishes the invalidation).
- Rework the SRSO mitigation to enable BP_SPEC_REDUCE only when KVM has at
least one active VM. Effectively BP_SPEC_REDUCE when KVM is loaded led
to very measurable performance regressions for non-KVM workloads.

fix IS_MNT_PROPAGATING uses
propagate_mnt() does not attach anything to mounts created during
propagate_mnt() itself. What's more, anything on ->mnt_slave_list
of such new mount must also be new, so we don't need to even look
there.
When move_mount() had been introduced, we've got an additional
class of mounts to skip - if we are moving from anon namespace,
we do not want to propagate to mounts we are moving (i.e. all
mounts in that anon namespace).
Unfortunately, the part about "everything on their ->mnt_slave_list
will also be ignorable" is not true - if we have propagation graph
A -> B -> C
and do OPEN_TREE_CLONE open_tree() of B, we get
A -> [B <-> B'] -> C
as propagation graph, where B' is a clone of B in our detached tree.
Making B private will result in
A -> B' -> C
C still gets propagation from A, as it would after making B private
if we hadn't done that open_tree(), but now the propagation goes
through B'. Trying to move_mount() our detached tree on subdirectory
in A should have
* moved B' on that subdirectory in A
* skipped the corresponding subdirectory in B' itself
* copied B' on the corresponding subdirectory in C.
As it is, the logics in propagation_next() and friends ends up
skipping propagation into C, since it doesn't consider anything
downstream of B'.
IOW, walking the propagation graph should only skip the ->mnt_slave_list
of new mounts; the only places where the check for "in that one
anon namespace" are applicable are propagate_one() (where we should
treat that as the same kind of thing as "mountpoint we are looking
at is not visible in the mount we are looking at") and
propagation_would_overmount(). The latter is better dealt with
in the caller (can_move_mount_beneath()); on the first call of
propagation_would_overmount() the test is always false, on the
second it is always true in "move from anon namespace" case and
always false in "move within our namespace" one, so it's easier
to just use check_mnt() before bothering with the second call and
be done with that.

do_move_mount(): don't leak MNTNS_PROPAGATING on failures
as it is, a failed move_mount(2) from anon namespace breaks
all further propagation into that namespace, including normal
mounts in non-anon namespaces that would otherwise propagate
there.

250cf36930 |
__legitimize_mnt(): check for MNT_SYNC_UMOUNT should be under mount_lock
... or we risk stealing final mntput from sync umount - raising mnt_count after umount(2) has verified that victim is not busy, but before it has set MNT_SYNC_UMOUNT; in that case __legitimize_mnt() doesn't see that it's safe to quietly undo mnt_count increment and leaves dropping the reference to caller, where it'll be a full-blown mntput(). Check under mount_lock is needed; leaving the current one done before taking that makes no sense - it's nowhere near common enough to bother with.

x86/mm: Eliminate window where TLB flushes may be inadvertently skipped
tl;dr: There is a window in the mm switching code where the new CR3 is
set and the CPU should be getting TLB flushes for the new mm. But
should_flush_tlb() has a bug and suppresses the flush. Fix it by
widening the window where should_flush_tlb() sends an IPI.
Long Version:
=== History ===
There were a few things leading up to this.
First, updating mm_cpumask() was observed to be too expensive, so it was
made lazier. But being lazy caused too many unnecessary IPIs to CPUs
due to the now-lazy mm_cpumask(). So code was added to cull
mm_cpumask() periodically[2]. But that culling was a bit too aggressive
and skipped sending TLB flushes to CPUs that need them. So here we are
again.
=== Problem ===
The too-aggressive code in should_flush_tlb() strikes in this window:
// Turn on IPIs for this CPU/mm combination, but only
// if should_flush_tlb() agrees:
cpumask_set_cpu(cpu, mm_cpumask(next));
next_tlb_gen = atomic64_read(&next->context.tlb_gen);
choose_new_asid(next, next_tlb_gen, &new_asid, &need_flush);
load_new_mm_cr3(need_flush);
// ^ After 'need_flush' is set to false, IPIs *MUST*
// be sent to this CPU and not be ignored.
this_cpu_write(cpu_tlbstate.loaded_mm, next);
// ^ Not until this point does should_flush_tlb()
// become true!
should_flush_tlb() will suppress TLB flushes between load_new_mm_cr3()
and writing to 'loaded_mm', which is a window where they should not be
suppressed. Whoops.
=== Solution ===
Thankfully, the fuzzy "just about to write CR3" window is already marked
with loaded_mm==LOADED_MM_SWITCHING. Simply checking for that state in
should_flush_tlb() is sufficient to ensure that the CPU is targeted with
an IPI.
This will cause more TLB flush IPIs. But the window is relatively small
and I do not expect this to cause any kind of measurable performance
impact.
Update the comment where LOADED_MM_SWITCHING is written since it grew
yet another user.
Peter Z also raised a concern that should_flush_tlb() might not observe
'loaded_mm' and 'is_lazy' in the same order that switch_mm_irqs_off()
writes them. Add a barrier to ensure that they are observed in the
order they are written.

drm/i915/dp: Fix determining SST/MST mode during MTP TU state computation
Determining the SST/MST mode during state computation must be done based on the output type stored in the CRTC state, which in turn is set once based on the modeset connector's SST vs. MST type and will not change as long as the connector is using the CRTC. OTOH the MST mode indicated by the given connector's intel_dp::is_mst flag can change independently of the above output type, based on what sink is at any moment plugged to the connector. Fix the state computation accordingly. Cc: Jani Nikula <jani.nikula@intel.com> Fixes: |

memblock: Accept allocated memory before use in memblock_double_array()
When increasing the array size in memblock_double_array() and the slab

reserve/allocate memory. However, the range returned may not have been
accepted, which can result in a crash when booting an SNP guest:

Mitigate this by calling accept_memory() on the memory range returned
before the slab is available.
Prior to v6.12, the accept_memory() interface used a 'start' and 'end'
parameter instead of 'start' and 'size', therefore the accept_memory()
call must be adjusted to specify 'start + size' for 'end' when applying
to kernels prior to v6.12.

bcachefs fixes for 6.15-rc6
- Some fixes to help with filesystem analysis: ensure superblock error count gets written if we go ERO, don't discard the journal aggressively (so it's available for list_journal -a). - Fix lost wakeup on arm causing us to get stuck when reading btree nodes. - Fix fsck failing to exit on ctrl-c. - An additional fix for filesystems with misaligned bucket sizes: we now ensure that allocations are properly aligned. - Setting background target but not promote target will now leave that data cached on the foreground target, as it used to. - Revert a change to when we allocate the VFS superblock, this was done for implementing blk_holder_ops but ended up not being needed, and allocating a superblock and not setting SB_BORN while we do recovery caused sync() calls and other things to hang. - Assorted fixes for harmless error messages that caused concern to users. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKnAFLkS8Qha+jvQrE6szbY3KbnYFAmgdDE0ACgkQE6szbY3K bnaKJA/+LGbMm1/dxCHSXP9CVbqB4cZL+UaP+01EDLXn+EQPrc1Zrt3TZznj79HR noCkX/L8hg8i06KNFYo4ZjARdt6Erlizoc3sy8QYKixyC3qzpiEwSt78aRufphWZ GO0GKkWuBrUC4Fsyc3lLmwcWCSMC7s4CofGsk4aprhddvv5taSR41CB2kxVa0t2c LFastz1kCglDWepND+1Ie6fsC3XNtd5X65bc4K7w2nS2/2Tlzcvh3If3wbNu2Edo /XMGyHJp0pcUT2UKJUp3a88HdjSrJLY2sP1B4+shs9McYhZ3xWq0okPjfcidDA0V eGlHpcrNMwWp4l0etROI0Qo97/jA+UTJc5uCXbReNWEdaFz0+w8VeEo1dJIGDJKR 5xLM2fkyFiar5ee7KlMdicxVMiKLgyy+V8NGUUWktLYyuoEb7bJIlnlqyxRVhCMn cLJ6AWwv7wmw40S74VHg5tjdkflB52BiJISK5I3FL1KCyz848nUzidEhYMCsPQaw AZJudl5FxymJMNQLKso7KyDE9ce9QbmUyQgHGDde3HkSEym1NuTNpeiMxZu/skPj JTlG/vFefQ0DhGcIF962rOAifdHS7YJftXo54YMtIbbix+RxyLRszet9QzJJxYlz sAQ8ncgL9hmhMZDj0ym88quLALmm3VJNcAb0TZVigf/HPX1Tx/U= =O9KF -----END PGP SIGNATURE----- Merge tag 'bcachefs-2025-05-08' of git://evilpiepirate.org/bcachefs Pull bcachefs fixes from Kent Overstreet: - Some fixes to help with filesystem analysis: ensure superblock error count gets written if we go ERO, don't discard the journal aggressively (so it's available for list_journal -a) - Fix lost wakeup on arm causing us to get stuck when reading btree nodes - Fix fsck failing to exit on ctrl-c - An additional fix for filesystems with misaligned bucket sizes: we now ensure that allocations are properly aligned - Setting background target but not promote target will now leave that data cached on the foreground target, as it used to - Revert a change to when we allocate the VFS superblock, this was done for implementing blk_holder_ops but ended up not being needed, and allocating a superblock and not setting SB_BORN while we do recovery caused sync() calls and other things to hang - Assorted fixes for harmless error messages that caused concern to users * tag 'bcachefs-2025-05-08' of git://evilpiepirate.org/bcachefs: bcachefs: Don't aggressively discard the journal bcachefs: Ensure superblock gets written when we go ERO bcachefs: Filter out harmless EROFS error messages bcachefs: journal_shutdown is EROFS, not EIO bcachefs: Call bch2_fs_start before getting vfs superblock bcachefs: fix hung task timeout in journal read bcachefs: Add missing barriers before wake_up_bit() bcachefs: Ensure proper write alignment bcachefs: Improve want_cached_ptr() bcachefs: thread_with_stdio: fix spinning instead of exiting |

drm/xe: Release force wake first then runtime power
xe_force_wake_get() is dependent on xe_pm_runtime_get(), so for the release path, xe_force_wake_put() should be called first then xe_pm_runtime_put(). Combine the error path and normal path together with goto. Fixes: |

drm/xe/gsc: do not flush the GSC worker from the reset path
The workqueue used for the reset worker is marked as WQ_MEM_RECLAIM, while the GSC one isn't (and can't be as we need to do memory allocations in the gsc worker). Therefore, we can't flush the latter from the former. The reason why we had such a flush was to avoid interrupting either the GSC FW load or in progress GSC proxy operations. GSC proxy operations fall into 2 categories: 1) GSC proxy init: this only happens once immediately after GSC FW load and does not support being interrupted. The only way to recover from an interruption of the proxy init is to do an FLR and re-load the GSC. 2) GSC proxy request: this can happen in response to a request that the driver sends to the GSC. If this is interrupted, the GSC FW will timeout and the driver request will be failed, but overall the GSC will keep working fine. Flushing the work allowed us to avoid interruption in both cases (unless the hang came from the GSC engine itself, in which case we're toast anyway). However, a failure on a proxy request is tolerable if we're in a scenario where we're triggering a GT reset (i.e., something is already gone pretty wrong), so what we really need to avoid is interrupting the init flow, which we can do by polling on the register that reports when the proxy init is complete (as that ensure us that all the load and init operations have been completed). Note that during suspend we still want to do a flush of the worker to make sure it completes any operations involving the HW before the power is cut. v2: fix spelling in commit msg, rename waiter function (Julia) Fixes: |
