Toshiba Portégé R100 has both acpi_video and toshiba_acpi vendor
backlight driver working. But none of them gets activated as it has
a VGA with no kernel driver (Trident CyberBlade XP4m32).
The DMI strings are very generic ("Portable PC") so add a custom
callback function to check for Trident CyberBlade XP4m32 PCI device
before enabling the vendor backlight driver (better than acpi_video
as it has more brightness steps).

There is a potential race condition in amdtee_close_session that may
cause use-after-free in amdtee_open_session. For instance, if a session
has refcount == 1, and one thread tries to free this session via:
kref_put(&sess->refcount, destroy_session);
the reference count will get decremented, and the next step would be to
call destroy_session(). However, if in another thread,
amdtee_open_session() is called before destroy_session() has completed
execution, alloc_session() may return 'sess' that will be freed up
later in destroy_session() leading to use-after-free in
amdtee_open_session.
To fix this issue, treat decrement of sess->refcount and removal of
'sess' from session list in destroy_session() as a critical section, so
that it is executed atomically.

When lots of quota changes are made, there may be cases in which an
inode's quota information is increased and then decreased, such as when
blocks are added to a file, then deleted from it. If the timing is
right, function do_qc can add pending quota changes to a transaction,
then later, another call to do_qc can negate those changes, resulting
in a net gain of 0. The quota_change information is recorded in the qc
buffer (and qd element of the inode as well). The buffer is added to the
transaction by the first call to do_qc, but a subsequent call changes
the value from non-zero back to zero. At that point it's too late to
remove the buffer_head from the transaction. Later, when the quota sync
code is called, the zero-change qd element is discovered and flagged as
an assert warning. If the fs is mounted with errors=panic, the kernel
will panic.
This is usually seen when files are truncated and the quota changes are
negated by punch_hole/truncate which uses gfs2_quota_hold and
gfs2_quota_unhold rather than block allocations that use gfs2_quota_lock
and gfs2_quota_unlock which automatically do quota sync.
This patch solves the problem by adding a check to qd_check_sync such
that net-zero quota changes already added to the transaction are no
longer deemed necessary to be synced, and skipped.
In this case references are taken for the qd and the slot from do_qc
so those need to be put. The normal sequence of events for a normal
non-zero quota change is as follows:
gfs2_quota_change
do_qc
qd_hold
slot_hold
Later, when the changes are to be synced:
gfs2_quota_sync
qd_fish
qd_check_sync
gets qd ref via lockref_get_not_dead
do_sync
do_qc(QC_SYNC)
qd_put
lockref_put_or_lock
qd_unlock
qd_put
lockref_put_or_lock
In the net-zero change case, we add a check to qd_check_sync so it puts
the qd and slot references acquired in gfs2_quota_change and skip the
unneeded sync.

io_lockdep_assert_cq_locked() checks that locking is correctly done when
a CQE is posted. If the ring is setup in a disabled state with
IORING_SETUP_R_DISABLED, then ctx->submitter_task isn't assigned until
the ring is later enabled. We generally don't post CQEs in this state,
as no SQEs can be submitted. However it is possible to generate a CQE
if tagged resources are being updated. If this happens and PROVE_LOCKING
is enabled, then the locking check helper will dereference
ctx->submitter_task, which hasn't been set yet.
Fixup io_lockdep_assert_cq_locked() to handle this case correctly. While
at it, convert it to a static inline as well, so that generated line
offsets will actually reflect which condition failed, rather than just
the line offset for io_lockdep_assert_cq_locked() itself.

syzbot reports that registering a mapped buffer ring on arm32 can
trigger an OOPS. Registered buffer rings have two modes, one of them
is the application passing in the memory that the buffer ring should
reside in. Once those pages are mapped, we use page_address() to get
a virtual address. This will obviously fail on highmem pages, which
aren't mapped.
Add a check if we have any highmem pages after mapping, and fail the
attempt to register a provided buffer ring if we do. This will return
the same error as kernels that don't support provided buffer rings to
begin with.

Improve intel_config_set_pull() implementation in Intel pinctrl driver by:
- Reducing scope of spinlock by moving unneeded operations out of it.
- Utilizing temporary variables for common operations.
- Limiting IO operations to positive cases.

Since Lynxpoint pinctrl device is not attached to acpi_lpss_pm_domain,
runtime PM serves no purpose here. Drop it and switch to pm_sleep_ptr()
as now we only have resume handle in place.

The kernel.h is a mess of unrelated things and we only used it
as a proxy to array_size.h, hence switch from former to the latter.

Since Baytrail pinctrl device is not attached to acpi_lpss_pm_domain,
runtime PM serves no purpose here. Drop it and switch to pm_sleep_ptr()
as now we only have suspend and resume handles in place.

While at it, group and sort the headers where it makes sense.

Touching files so used for the kernel,
forces 'make' to recompile most of the kernel.
Having those definitions in more granular files
helps avoid recompiling so much of the kernel.
