commit 62e72d2cf702
So make madvise(..., MADV_COLLAPSE) also call xas_set_lru() to pass the
list_lru which we may want to insert xa_node into later. And move
mapping_set_update to mm/internal.h, and turn into a macro to avoid
including extra headers in mm/internal.h.
Take it up with Kairui. And whoever it was added that patch to
linux-mm.
