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 warns if a printf format string is empty (apparently), so
clang does too; under -Wformat-zero-length
give these some more detailed error messages, which should be more useful anyway.

David,
Please send this on top of Linux 6.9-rc6 - this one doesn't apply as is due to conflict between this one and fca7526b7d89
I think if we can fix this here - we won't problems during pull request merge.
thanks, -- Shuah
