[PATCH] ARM: mm: align hugetlb mappings to the huge page size

[Karl Mehltretter]

Hi,

A friendly ping on this patch. I came across the ARM32 alignment
issue again while testing Ackerley's HugeTLB subpool series [1]
on v7.3-rc3 in QEMU (Cortex-A15, LPAE).

I've now retested with this alignment fix applied on top of the
full series, keeping the kernel configuration and test image
unchanged. All six ordinary HugeTLB mapping and cleanup tests
pass with both one and four virtual CPUs, without the previously
observed panic.

Would someone have a chance to take a look? Happy to provide the
configuration and logs if useful.

Thanks,
