splice: missing user pointer access verification (CVE-2008-0009/10)
patch 8811930dc74a503415b35c4a79d14fb0b408a361 in mainline.
vmsplice_to_user() must always check the user pointer and length
with access_ok() before copying. Likewise, for the slow path of
copy_from_user_mmap_sem() we need to check that we may read from
the user region.
