fc9a615200 drm: tests: Fix invalid printf format specifiers in KUnit tests 
The drm_buddy_test's alloc_contiguous test used a u64 for the page size,
which was then updated to be an 'unsigned long' to avoid 64-bit
multiplication division helpers.

However, the variable is logged by some KUNIT_ASSERT_EQ_MSG() using the
'%d' or '%llu' format specifiers, the former of which is always wrong,
and the latter is no longer correct now that ps is no longer a u64. Fix
these to all use '%lu'.

Also, drm_mm_test calls KUNIT_FAIL() with an empty string as the
message. gcc and clang warns if a printf format string is empty, so
give these some more detailed error messages, which should be more
useful anyway.

Fixes: a64056bb5a ("drm/tests/drm_buddy: add alloc_contiguous test")
Fixes: fca7526b7d ("drm/tests/drm_buddy: fix build failure on 32-bit targets")
Fixes: fc8d29e298 ("drm: selftest: convert drm_mm selftest to KUnit")

drm/tests: mm: Call drm_mm_print in drm_test_mm_debug 
The original intent behind the test was to sanity check whether calling
the debug iterator (drm_mm_print) doesn't cause any problems.
Unfortunately - this call got accidentally removed during KUnit
transition. Restore it.

drm/tests: Remove slow tests 
Both the drm_buddy and drm_mm tests have been converted from selftest to
kunit recently.

However, a significant portion of them are trying to exert some part of
their API over a huge number of iterations and with random variations of
their parameters.  They are thus more a way to discover new bugs than
actual unit tests.

This is fine in itself but leads to very slow runtime (up to 25s for
some drm_test_mm_reserve and drm_test_mm_insert on a Ryzen 7950x while
running the tests in qemu) which make them a poor fit for kunit.

Let's remove those tests from the drm_mm and drm_buddy test suites for
now, and if it's ever needed we can always create proper unit tests for
them later on.

This made the entire DRM tests execution time (as of v6.6-rc1) come from
65s to less than .5s on a Ryzen 7950x system when running under qemu,
and from 9 minutes to about 4s on a RaspberryPi4.

drm/tests: Fix incorrect argument in drm_test_mm_insert_range 
While drm_mm test was converted form igt selftest to kunit, unexpected
value of "end" argument equal "start" was introduced to one of calls to a
function that executes the drm_test_mm_insert_range for specific start/end
pair of arguments.  As a consequence, DRM_MM_BUG_ON(end <= start) is
triggered.  Fix it by restoring the original value.

523dfa96ad drm/tests: reduce drm_mm_test stack usage 
The check_reserve_boundaries function uses a lot of kernel stack,
and it gets inlined by clang, which makes __drm_test_mm_reserve
use even more of it, to the point of hitting the warning limit:

drivers/gpu/drm/tests/drm_mm_test.c:344:12: error: stack frame size (1048) exceeds limit (1024) in '__drm_test_mm_reserve' [-Werror,-Wframe-larger-than]

When building with gcc, this does not happen, but the structleak
plugin can similarly increase the stack usage and needs to be
disabled, as we do for all other kunit users.

ce28ab1380 drm/tests: Add back seed value information 
As reported by Michał, the drm_mm and drm_buddy unit tests lost the
printk with seed value after they were refactored into KUnit.

Add kunit_info with seed value information to assure reproducibility.

a251c17aa5 treewide: use get_random_u32() when possible 
The prandom_u32() function has been a deprecated inline wrapper around
get_random_u32() for several releases now, and compiles down to the
exact same code. Replace the deprecated wrapper with a direct call to
the real function. The same also applies to get_random_int(), which is
just a wrapper around get_random_u32(). This was done as a basic find
and replace.

961bcdf956 drm/tests: Change "igt_" prefix to "drm_test_" 
With the introduction of KUnit, IGT is no longer the only option to run
the DRM unit tests, as the tests can be run through kunit-tool or on
real hardware with CONFIG_KUNIT.

Therefore, remove the "igt_" prefix from the tests and replace it with
the "drm_test_" prefix, making the tests' names independent from the tool
used.
