Hi,

While the patch works standalone. It would be better if it'd go through the
same tree as the other patches in this series. Patch 1 removes the unused
vmlist field from the mm_context_t struct in asm-generic/mmu.h. So without that
patch this patch basically doubles the size of your mm_context_t.
