v3.x changed the how vram width was encoded. The previous
implementation actually worked correctly for most boards.
Fix the implementation to work correctly everywhere.
This fixes the vram width reported in the kernel log on
some boards.

Changes the create_cq verb signature by sending the entire uverbs attr
bundle as a parameter. This allows drivers to send driver specific attrs
through ioctl for the create_cq verb and access them in their driver
specific code.
Also adds a new enum value for driver specific ioctl attributes for
methods already supporting UHW.

The newly used helper also checks for empty ("") paths.
NULL paths with any flag value other than AT_EMPTY_PATH go the usual
route and end up with -EFAULT to retain compatibility (Rust is abusing
calls of the sort to detect availability of statx).
This avoids path lookup code, lockref management, memory allocation and
in case of NULL path userspace memory access (which can be quite
expensive with SMAP on x86_64).
Benchmarked with statx(..., AT_EMPTY_PATH, ...) running on Sapphire
Rapids, with the "" path for the first two cases and NULL for the last
one.

Building with W=1 in some configurations produces a false positive
warning for kallsyms:
kernel/kallsyms.c: In function '__sprint_symbol.isra':
kernel/kallsyms.c:503:17: error: 'strcpy' source argument is the same as destination [-Werror=restrict]
503 | strcpy(buffer, name);
| ^~~~~~~~~~~~~~~~~~~~
This originally showed up while building with -O3, but later started
happening in other configurations as well, depending on inlining
decisions. The underlying issue is that the local 'name' variable is
always initialized to the be the same as 'buffer' in the called functions
that fill the buffer, which gcc notices while inlining, though it could
see that the address check always skips the copy.
The calling conventions here are rather unusual, as all of the internal
lookup functions (bpf_address_lookup, ftrace_mod_address_lookup,
ftrace_func_address_lookup, module_address_lookup and
kallsyms_lookup_buildid) already use the provided buffer and either return
the address of that buffer to indicate success, or NULL for failure,
but the callers are written to also expect an arbitrary other buffer
to be returned.
Rework the calling conventions to return the length of the filled buffer
instead of its address, which is simpler and easier to follow as well
as avoiding the warning. Leave only the kallsyms_lookup() calling conventions
unchanged, since that is called from 16 different functions and
adapting this would be a much bigger change.

linereq_set_config() behaves badly when direction is not set.
The configuration validation is borrowed from linereq_create(), where,
to verify the intent of the user, the direction must be set to in order to
effect a change to the electrical configuration of a line. But, when
applied to reconfiguration, that validation does not allow for the unset
direction case, making it possible to clear flags set previously without
specifying the line direction.
Adding to the inconsistency, those changes are not immediately applied by
linereq_set_config(), but will take effect when the line value is next get
or set.
For example, by requesting a configuration with no flags set, an output
line with GPIO_V2_LINE_FLAG_ACTIVE_LOW and GPIO_V2_LINE_FLAG_OPEN_DRAIN
set could have those flags cleared, inverting the sense of the line and
changing the line drive to push-pull on the next line value set.
Skip the reconfiguration of lines for which the direction is not set, and
only reconfigure the lines for which direction is set.

Print the guest's random seed during VM creation if and only if the seed
has changed since the seed was last printed. The vast majority of tests,
if not all tests at this point, set the seed during test initialization
and never change the seed, i.e. printing it every time a VM is created is
useless noise.
Snapshot and print the seed during early selftest init to play nice with
tests that use the kselftests harness, at the cost of printing an unused
seed for tests that change the seed during test-specific initialization,
e.g. dirty_log_perf_test. The kselftests harness runs each testcase in a
separate process that is forked from the original process before creating
each testcase's VM, i.e. waiting until first VM creation will result in
the seed being printed by each testcase despite it never changing. And
long term, the hope/goal is that setting the seed will be handled by the
core framework, i.e. that the dirty_log_perf_test wart will naturally go
away.

Move reset controller registration to the end in rzg2l-usbphy-ctrl, to
simplify the probe error path, add a new i.MX8MP AudioMix reset driver,
allow to build some drivers under COMPILE_TEST with fewer dependencies,
and use the devm_clk_get_enabled convenience wrapper in meson-audio-arb.
The latter causes a trivial merge conflict [1] with
b99e9c0961 ("reset: meson-audio-arb: Convert to platform remove callback returning void")
because I didn't manage to send that in last round. There is no overlap
though.
