Subject: [PATCHES] uaccess simple access_ok() removals

	One of the uaccess-related branches; this one is just the
cases when access_ok() calls are trivially pointless - the address
in question gets fed only to primitives that do access_ok() checks
themselves.  This stuff sits in
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git #uaccess.access_ok
and it's on top of #fixes (which is already merged into mainline on
Apr 28).
	Individual patches in followups; if nobody screams - into #for-next
it goes...

	There are other uaccess-related branches; I'll be posting them
for review over the next few days.  My apologies if this one comes with
a buggered Cc - this is the first time I have to deal with a series with
Cc lists varying that much; I hope I manage to get git-send-email do
the right thing, but...
