  selftests/mm: fix cross compilation with LLVM (2023-06-19 13:19:35 -0700)

----------------------------------------------------------------
19 hotfixes.  8 of these are cc:stable.

This includes a wholesale reversion of the post-6.4 series "make slab shrink

https://lkml.kernel.org/r/ZH6K0McWBeCjaf16@xxxxxxxxxxxxxxxxxxx.
