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]
[1] https://lore.kernel.org/r/20241118214650.3667577-1-kalesh...
Thanks,
Kalesh
