SM6115's SMMU uses 36bit VAs, which is a good indicator that we
should increase (dma-)ranges - and by extension #address- and
#size-cells to prevent things from getting lost in translation
(both literally and figuratively). Do so.

Cursor gets clipped off in the middle of the screen with hw rotation
180. Fix a miscalculation of cursor offset when it's placed near the
edges in the pipe split case.
Cursor bugs with hw rotation were reported on AMD issue tracker:
https://gitlab.freedesktop.org/drm/amd/-/issues/2247
The issues on rotation 270 was fixed by:
https://lore.kernel.org/amd-gfx/20221118125935.4013669-22-Brian.Chang@amd.com/
that partially addressed the rotation 180 too. So, this patch is the
final bits for rotation 180.

down to files residing in link folder based on functionality. This
change is the last break down change which will remove dc_link.c

This commit adds support for the ufi-001C and uf896 WiFi/LTE dongle made by
Tong Heng Wei Chuang based on MSM8916.
uf896 is another variant for the usb stick. The board design
differs by using different gpios for the keys and leds.
Note: The original firmware does not support 64-bit OS. It is necessary
to flash 64-bit TZ firmware to boot arm64.
Currently supported:
- All CPU cores
- Buttons
- LEDs
- Modem
- SDHC
- USB Device Mode
- UART

Add a simple way of redirecting calls to functions by including a
special prologue in the "real" function which checks to see if the
replacement function should be called (and, if so, calls it).
To redirect calls to a function, make the first (non-declaration) line
of the function:
KUNIT_STATIC_STUB_REDIRECT(function_name, [function arguments]);
(This will compile away to nothing if KUnit is not enabled, otherwise it
will check if a redirection is active, call the replacement function,
and return. This check is protected by a static branch, so has very
little overhead when there are no KUnit tests running.)
Calls to the real function can be redirected to a replacement using:
kunit_activate_static_stub(test, real_fn, replacement_fn);
The redirection will only affect calls made from within the kthread of
the current test, and will be automatically disabled when the test
completes. It can also be manually disabled with
kunit_deactivate_static_stub().
The 'example' KUnit test suite has a more complete example.

KUnit has several macros and functions intended for use from non-test
code. These hooks, currently the kunit_get_current_test() and
kunit_fail_current_test() macros, didn't work when CONFIG_KUNIT=m.
In order to support this case, the required functions and static data
need to be available unconditionally, even when KUnit itself is not
built-in. The new 'hooks.c' file is therefore always included, and has
both the static key required for kunit_get_current_test(), and a table
of function pointers in struct kunit_hooks_table. This is filled in with
the real implementations by kunit_install_hooks(), which is kept in
hooks-impl.h and called when the kunit module is loaded.
This can be extended for future features which require similar
"hook" behaviour, such as static stubs, by simply adding new entries to
the struct, and the appropriate code to set them.
Fixed white-space errors during commit:

Commit 3bc753c06dd0 ("kbuild: treat char as always unsigned") broke
kprobes. Setting a probe-point on 1 byte conditional jump can cause the
kernel to crash when the (signed) relative jump offset gets treated as
unsigned.
Fix by replacing the unsigned 'immediate.bytes' (plus a cast) with the
signed 'immediate.value' when assigning to the relative jump offset.

Cong pointed out that there are some inconsistencies between the BPF design
QA and the lifecycle expectations documentation we added for kfuncs. Let's
update the QA file to be consistent with the kfunc docs, and add references
where it makes sense. Also document that modules may export kfuncs now.

The memory allocators are available during early boot even in the phase
where interrupts are disabled and scheduling is not yet possible.
The setup is so that GFP_KERNEL allocations work in this phase without
causing might_alloc() splats to be emitted because the system state is
SYSTEM_BOOTING at that point which prevents the warnings to trigger.
Most allocation/free functions use local_irq_save()/restore() or a lock
variant of that. But kmem_cache_alloc_bulk() and kmem_cache_free_bulk() use
local_[lock]_irq_disable()/enable(), which leads to a lockdep warning when
interrupts are enabled during the early boot phase.
This went unnoticed so far as there are no early users of these
interfaces. The upcoming conversion of the interrupt descriptor store from
radix_tree to maple_tree triggered this warning as maple_tree uses the bulk
interface.
Cure this by moving the kmem_cache_alloc/free() bulk variants of SLUB and
SLAB to local[_lock]_irq_save()/restore().
There is obviously no reclaim possible and required at this point so there
is no need to expand this coverage further.
No functional change.

Intel SDM (December 2022) vol3B 17.13.2 contains IMC MC error codes
for Sapphire Rapids. Current i10nm_edac only supports firmware decoder
(ACPI DSM methods) for Sapphire Rapids. So add the driver decoder
(decoding DDR memory errors via extracting error information from the
IMC MC error codes) for Sapphire Rapids for better decoding performance.

As discussed[*], relabel the poorly named structs to align with the
current KVM nomenclature.
Old names are a leftover from before commit 52491a38b2c2 ("KVM:
Initialize gfn_to_pfn_cache locks in dedicated helper"), which i.a.
introduced kvm_gpc_init() and renamed kvm_gfn_to_pfn_cache_init()/
_destroy() to kvm_gpc_activate()/_deactivate(). Partly in an effort
to avoid implying that the cache really is destroyed/freed.
While at it, get rid of #define GPA_INVALID, which being used as a GFN,
is not only misnamed, but also unnecessarily reinvents a UAPI constant.
No functional change intended.

but does not adjust the usage of this function prototype in util/pfm.c.
In file util/pfm.c function print_event() is still invoked with 13
parameters instead of 11. The compile fails.
When I adjust the file util/pfm.c as in this patch, the build works file.
Please check this patch for correctness, I have just fixed the compile

When there're many lock contentions in the system, people sometimes want
to know who caused the contention, IOW who's the owner of the locks.
The -o/--lock-owner option tries to follow the lock owners for the
contended mutexes and rwsems from BPF, and then attributes the
contention time to the owner instead of the waiter. It's a best effort
approach to get the owner info at the time of the contention and doesn't
guarantee to have the precise tracking of owners if it's changing over
time.
Currently it only handles mutex and rwsem that have owner field in their
struct and it basically points to a task_struct that owns the lock at
the moment.
Technically its type is atomic_long_t and it comes with some LSB bits
used for other meanings. So it needs to clear them when casting it to a
pointer to task_struct.
Also the atomic_long_t is a typedef of the atomic 32 or 64 bit types
depending on arch which is a wrapper struct for the counter value. I'm
not aware of proper ways to access those kernel atomic types from BPF so
I just read the internal counter value directly. Please let me know if
there's a better way.
When -o/--lock-owner option is used, it goes to the task aggregation
mode like -t/--threads option does. However it cannot get the owner for
other lock types like spinlock and sometimes even for mutex.

As you can see, the owner is unknown for the most cases. But if we
filter only for the mutex locks, it'd more likely get the onwers.
