Series mm, dma, arm64: Reduce ARCH_KMALLOC_MINALIGN to 8 | expand

Commit Message

Catalin Marinas Nov. 6, 2022, 10:01 p.m. UTC 
create_kmalloc_cache() is now only called from new_kmalloc_cache() in
the same file, so make it static. In addition, the useroffset argument
is always 0 while usersize is the same as size. Remove them.
