[PATCH mm-unstable 00/17] mm: Introduce arch_mmap_hint()

Hi all,

This series introduces aarch_mmap_hint() to handle allocating VA space
for the hint address.

Patches 1-16 introduce this new helper and Patch 17 uses it to fix the
issue of mmap hint being ignored in some cases due to THP alignment [1]

Thanks,
