As pointed out by Bjorn and Mike in [1], we can simplify the handling
of enable_mask-based BCMs. This series attempts to do so and fixes a bug
that snuck in.
Gave a quick spin on 8450, doesn't seem to have exploded.

BCMs with an enable_mask expect to only have that specific value written
to them. The current implementation only works by miracle for BCMs with
enable mask == BIT(0), as the minimal vote we've been using so far just
so happens to be equal to that.
Use the correct value with keepalive voting.

We don't need all the complex arithmetic for BCMs utilizing enable_mask,
as all we need to do is to determine whether there's any user (or
keepalive) asking for it to be on.
Separate the logic for such BCMs for a small speed boost.

Teach lockdep that icc_bw_lock is needed in code paths that could

For cases where icc_bw_set() can be called in callbaths that could
deadlock against shrinker/reclaim, such as runpm resume, we need to
decouple the icc locking. Introduce a new icc_bw_lock for cases where
we need to serialize bw aggregation and update to decouple that from
paths that require memory allocation such as node/link creation/
destruction.

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by for struct icc_onecell_data.
Additionally, since the element count member must be set before accessing
the annotated flexible array member, move its initialization earlier.

chassis-type
The lenovo-ymc driver is causing the keyboard + touchpad to stop working
on some regular laptop models such as the Lenovo ThinkBook 13s G2 ITL 20V9.
The problem is that there are YMC WMI GUID methods in the ACPI tables
of these laptops, despite them not being Yogas and lenovo-ymc loading
causes libinput to see a SW_TABLET_MODE switch with state 1.
This in turn causes libinput to ignore events from the builtin keyboard
and touchpad, since it filters those out for a Yoga in tablet mode.
Similar issues with false-positive SW_TABLET_MODE=1 reporting have
been seen with the intel-hid driver.
Copy the intel-hid driver approach to fix this and only bind to the WMI
device on machines where the DMI chassis-type indicates the machine
is a convertible.
Add a 'force' module parameter to allow overriding the chassis-type check
so that users can easily test if the YMC interface works on models which
report an unexpected chassis-type.

The only remaining consumer is new_inode, where it showed up in 2001 as
commit c37fa164f793 ("v2.4.9.9 -> v2.4.9.10") in a historical repo [1]
with a changelog which does not mention it.
Since then the line got only touched up to keep compiling.
While it may have been of benefit back in the day, it is guaranteed to
at best not get in the way in the multicore setting -- as the code
performs *a lot* of work between the prefetch and actual lock acquire,
any contention means the cacheline is already invalid by the time the
routine calls spin_lock(). It adds spurious traffic, for short.
On top of it prefetch is notoriously tricky to use for single-threaded
purposes, making it questionable from the get go.
As such, remove it.
I admit upfront I did not see value in benchmarking this change, but I
can do it if that is deemed appropriate.
Removal from new_inode and of the entire thing are in the same patch as
requested by Linus, so whatever weird looks can be directed at that guy.

Pull zonefs fix from Damien Le Moal:
- The switch to using iomap for executing a direct synchronous write to
sequential files using a zone append BIO overlooked cases where the
BIO built by iomap is too large and needs splitting, which is not
allowed with zone append.
Fix this by using regular write commands instead. The use of zone
append commands will be reintroduced later with proper support from
iomap.
