Boris Brezillion needs the gem lru fixes 379e8f1ca5e9 ("drm/gem: Make
the GEM LRU lock part of drm_device") backmerged for drm-misc-next.
That also means we need to sort out the rename conflict in panthor with
the fixup patch from Boris from drm-tip.

dma_resv_wait_timeout() returns a positive 'remaining jiffies' value
on success, 0 on timeout, and -errno on failure.

panfrost_ioctl_wait_bo() returns this 'long' result from an int-typed
ioctl handler, so positive values reach userspace as bogus errors.
Explicitly set ret to 0 on the success path.

RZ/G3L SoC is embedded with Mali-G31 GPU system. Add GPU_PM_RT support as
it needs to be assert/deassert the reset during suspend/resume.

On RZ/G2L SoCs, the GPU MMU requires a bus_ace clock to operate correctly.
Without it, unbind/bind cycles leave the GPU non-operational, manifesting
as an AS_ACTIVE bit stuck and a soft reset timeout falling back to hard
reset. Add bus_ace_clock as an optional clock, wiring it into init/fini,
and the runtime suspend/resume paths alongside the existing optional
bus_clock.

The clk_enable() and clk_disable() APIs already handle NULL clock pointers
gracefully — clk_enable() returns 0 and clk_disable() returns immediately
when passed a NULL or optional clock. The explicit if (pfdev->bus_clock)
guards around these calls in the runtime suspend/resume paths are
therefore unnecessary. Remove them to simplify the code.

Instead of testing import_attach for imported GEM buffers, invoke
drm_gem_is_imported() to do the test. The test itself does not change.

This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".
