This was entirely automated, using the script by Al:
PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*<asm/uaccess.h>'
sed -i -e "s!$PATT!#include <linux/uaccess.h>!" \
$(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h)
to do the replacement at the end of the merge window.

commit 77d6273e79e3a86552fcf10cdd31a69b46ed2ce6 upstream.
call12 can't be safely used as the first call in the inline function,
because the compiler does not extend the stack frame of the bounding
function accordingly, which may result in corruption of local variables.
If a call needs to be done, do call8 first followed by call12.
For pure assembly code in _switch_to increase stack frame size of the
bounding function.

commit 4229fb12a03e5da5882b420b0aa4a02e77447b86 upstream.
Userspace return code may skip restoring THREADPTR register if there are
no registers that need to be zeroed. This leads to spurious failures in
libc NPTL tests.
Always restore THREADPTR on return to userspace.
