Hi, This is a patchset for hugepage migration. There are many users of page migration such as soft offlining, memory hotplug, memory policy and memory compaction, but this patchset adds hugepage support only for soft offlining as the first step. This patchset is based on 2.6.35-rc3 applied with "HWPOISON for hugepage" patchset I previously posted (see Andi's git tree.) http://git.kernel.org/?p=linux/kernel/git/ak/linux-mce-2.6.git;a=summary I tested this patchset with 'make func' in libhugetlbfs and have gotten the same result as one from 2.6.35-rc3.
