Subject: [PATCH 0/2] hugetlbfs: support split page table lock

Hi,

In previous discussion [1] on "extend hugepage migration" patches, Michal and
Kosaki-san commented that in the patch "migrate: add migrate_entry_wait_huge()"
we need to solve the issue in the arch-independent manner and had better care
USE_SPLIT_PTLOCK=y case. So this patch(es) does that.

I made sure that the patched kernel shows no regression in functional tests
of libhugetlbfs.

Thanks,
