The worker is canceled in gt_park path, but earlier it was assumed that
gt_park path cannot sleep and the cancel is asynchronous. This caused a
race with suspend flow where the worker runs after suspend and causes an
unclaimed register access warning. Cancel the worker synchronously since
the gt_park is indeed allowed to sleep.

The iwlmei driver breaks iwlwifi when returning from suspend. The interface
ends up in the 'down' state after coming back from suspend. And iwd doesn't
touch the interface state, but wpa_supplicant does, so the bug only happens on
iwd.
The bug report[0] has been open for four months now, and no fix seems to be
forthcoming. Since just disabling the iwlmei driver works as a workaround,
let's mark the config option as broken until it can be fixed properly.

migrate_vma_setup() has a fast path in migrate_vma_collect_pmd() that
installs migration entries directly if it can lock the migrating page.
When removing a dirty pte the dirty bit is supposed to be carried over to
the underlying page to prevent it being lost.
Currently migrate_vma_*() can only be used for private anonymous mappings.
That means loss of the dirty bit usually doesn't result in data loss
because these pages are typically not file-backed. However pages may be
backed by swap storage which can result in data loss if an attempt is made
to migrate a dirty page that doesn't yet have the PageDirty flag set.
In this case migration will fail due to unexpected references but the
dirty pte bit will be lost. If the page is subsequently reclaimed data
won't be written back to swap storage as it is considered uptodate,
resulting in data loss if the page is subsequently accessed.
Prevent this by copying the dirty bit to the page when removing the pte to
match what try_to_migrate_one() does.

When clearing a PTE the TLB should be flushed whilst still holding the PTL
to avoid a potential race with madvise/munmap/etc. For example consider
the following sequence:
CPU0 CPU1
---- ----
migrate_vma_collect_pmd()
pte_unmap_unlock()
madvise(MADV_DONTNEED)
-> zap_pte_range()
pte_offset_map_lock()
[ PTE not present, TLB not flushed ]
pte_unmap_unlock()
[ page is still accessible via stale TLB ]
flush_tlb_range()
In this case the page may still be accessed via the stale TLB entry after
madvise returns. Fix this by flushing the TLB while holding the PTL.

Commit 4867fbbdd6b3 ("x86/mm: move protection_map[] inside the platform")
moved accesses to protection_map[] from mem_encrypt_amd.c to pgprot.c. As
a result, the accesses are now targets of KASAN (and other
instrumentations), leading to the crash during the boot process.
Disable the instrumentations for pgprot.c like commit 67bb8e999e0a
("x86/mm: Disable various instrumentations of mm/mem_encrypt.c and
mm/tlb.c").
Before this patch, my AMD machine cannot boot since v6.0-rc1 with KASAN
enabled, without anything printed. After the change, it successfully
boots up.

In the case where a filesystem is polled to take over the memory failure
and receives -EOPNOTSUPP it indicates that page->index and page->mapping
are valid for reverse mapping the failure address. Introduce
FSDAX_INVALID_PGOFF to distinguish when add_to_kill() is being called from
mf_dax_kill_procs() by a filesytem vs the typical memory_failure() path.
Otherwise, vma_pgoff_address() is called with an invalid fsdax_pgoff which
then trips this failing signature:

Patch series "mm, xfs, dax: Fixes for memory_failure() handling".
I failed to run the memory error injection section of the ndctl test suite
on linux-next prior to the merge window and as a result some bugs were
missed. While the new enabling targeted reflink enabled XFS filesystems
the bugs cropped up in the surrounding cases of DAX error injection on
ext4-fsdax and device-dax.
One new assumption / clarification in this set is the notion that if a
filesystem's ->notify_failure() handler returns -EOPNOTSUPP, then it must
be the case that the fsdax usage of page->index and page->mapping are
valid. I am fairly certain this is true for xfs_dax_notify_failure(), but
would appreciate another set of eyes.
This patch (of 4):
XFS always registers dax_holder_operations regardless of whether the
filesystem is capable of handling the notifications. The expectation is
that if the notify_failure handler cannot run then there are no scenarios
where it needs to run. In other words the expected semantic is that
page->index and page->mapping are valid for memory_failure() when the
conditions that cause -EOPNOTSUPP in xfs_dax_notify_failure() are present.
A fallback to the generic memory_failure() path is expected so do not warn
when that happens.

allocation
Patrick Daly reported the following problem;
NODE_DATA(nid)->node_zonelists[ZONELIST_FALLBACK] - before offline operation
[0] - ZONE_MOVABLE
[1] - ZONE_NORMAL
[2] - NULL
For a GFP_KERNEL allocation, alloc_pages_slowpath() will save the
offset of ZONE_NORMAL in ac->preferred_zoneref. If a concurrent
memory_offline operation removes the last page from ZONE_MOVABLE,
build_all_zonelists() & build_zonerefs_node() will update
node_zonelists as shown below. Only populated zones are added.
NODE_DATA(nid)->node_zonelists[ZONELIST_FALLBACK] - after offline operation
[0] - ZONE_NORMAL
[1] - NULL
[2] - NULL
The race is simple -- page allocation could be in progress when a memory
hot-remove operation triggers a zonelist rebuild that removes zones. The
allocation request will still have a valid ac->preferred_zoneref that is
now pointing to NULL and triggers an OOM kill.
This problem probably always existed but may be slightly easier to trigger
due to 6aa303defb74 ("mm, vmscan: only allocate and reclaim from zones
with pages managed by the buddy allocator") which distinguishes between
zones that are completely unpopulated versus zones that have valid pages
not managed by the buddy allocator (e.g. reserved, memblock, ballooning
etc). Memory hotplug had multiple stages with timing considerations
around managed/present page updates, the zonelist rebuild and the zone
span updates. As David Hildenbrand puts it
memory offlining adjusts managed+present pages of the zone
essentially in one go. If after the adjustments, the zone is no
longer populated (present==0), we rebuild the zone lists.
Once that's done, we try shrinking the zone (start+spanned
pages) -- which results in zone_start_pfn == 0 if there are no
more pages. That happens *after* rebuilding the zonelists via
remove_pfn_range_from_zone().
The only requirement to fix the race is that a page allocation request
identifies when a zonelist rebuild has happened since the allocation
request started and no page has yet been allocated. Use a seqlock_t to
track zonelist updates with a lockless read-side of the zonelist and
protecting the rebuild and update of the counter with a spinlock.

The AMD IOMMU driver cannot activate PASID mode on a RID without the RID's
translation being set to IDENTITY. Further it requires changing the RID's
page table layout from the normal v1 IOMMU_DOMAIN_IDENTITY layout to a
different v2 layout.
It does this by creating a new iommu_domain, configuring that domain for
v2 identity operation and then attaching it to the group, from within the
driver. This logic assumes the group is already set to the IDENTITY domain
and is being used by the DMA API.
However, since the ownership logic is based on the group's domain pointer
equaling the default domain to detect DMA API ownership, this causes it to
look like the group is not attached to the DMA API any more. This blocks
attaching drivers to any other devices in the group.
In a real system this manifests itself as the HD-audio devices on some AMD
platforms losing their device drivers.
Work around this unique behavior of the AMD driver by checking for
equality of IDENTITY domains based on their type, not their pointer
value. This allows the AMD driver to have two IDENTITY domains for
internal purposes without breaking the check.
Have the AMD driver properly declare that the special domain it created is
actually an IDENTITY domain.

The global rwsem dmar_global_lock was introduced by commit 3a5670e8ac932
("iommu/vt-d: Introduce a rwsem to protect global data structures"). It
is used to protect DMAR related global data from DMAR hotplug operations.
The dmar_global_lock used in the intel_iommu_init() might cause recursive
locking issue, for example, intel_iommu_get_resv_regions() is taking the
dmar_global_lock from within a section where intel_iommu_init() already
holds it via probe_acpi_namespace_devices().
Using dmar_global_lock in intel_iommu_init() could be relaxed since it is
unlikely that any IO board must be hot added before the IOMMU subsystem is
initialized. This eliminates the possible recursive locking issue by moving
down DMAR hotplug support after the IOMMU is initialized and removing the
uses of dmar_global_lock in intel_iommu_init().

We fixed the potential deadlock at dynamic unbinding the HD-audio
codec at the commit 7206998f578d ("ALSA: hda: Fix potential deadlock
at codec unbinding"), but ironically, this caused another potential
deadlock. The current code uses refcount_dec() and waits for the
pending task with wait_event for dropping the refcount to 0. This
works fine when PCMs are assigned and actually waiting for the
refcount drop.
Meanwhile, when there was no PCM assigned, the refcount_dec() call
itself was supposed to drop to zero -- alas, it doesn't in reality;
refcount_dec() complains, spews kernel warning and it saturates
instead of dropping to 0, due to the nature of refcount_dec()
implementation. This eventually blocks the wait_event() wakeup and
the code get stuck there.
For avoiding the problem, we call refcount_dec_and_test() and skips
the sync-wait if it already reaches to zero.
The patch does a slight code reshuffling to make sure to invoke other
disconnect calls before the sync-wait, too.

Pull driver core fixes from Greg KH:
"Here are some small driver core and debugfs fixes for 6.0-rc5.
Included in here are:
- multiple attempts to get the arch_topology code to work properly on
non-cluster SMT systems. First attempt caused build breakages in
linux-next and 0-day, second try worked.
- debugfs fixes for a long-suffering memory leak. The pattern of
debugfs_remove(debugfs_lookup(...)) turns out to leak dentries, so
add debugfs_lookup_and_remove() to fix this problem. Also fix up
the scheduler debug code that highlighted this problem. Fixes for
other subsystems will be trickling in over the next few months for
this same issue once the debugfs function is merged.
All of these have been in linux-next since Wednesday with no reported
problems"
