Brice Goglin 80bba1290a mm: no get_user/put_user while holding mmap_sem in do_pages_stat? ... Since commit 2f007e74bb, do_pages_stat() gets the page address from user-space and puts the corresponding status back while holding the mmap_sem for read. There is no need to hold mmap_sem there while some page-faults may occur. This patch adds a temporary address and status buffer so as to only hold mmap_sem while working on these kernel buffers. This is implemented by extracting do_pages_stat_array() out of do_pages_stat().
