[PATCH v2 15/16] uaccess: Mark pagefault_disable() and pagefault_enable() notrace

[Song Liu]

copy_to_kernel_nofault() and copy_to_user_nofault() are declared
notrace in <linux/uaccess.h>. They call pagefault_disable() and
pagefault_enable(), which are plain inline functions, so an out-of-line
copy is untraced only because inline implies notrace.

Mark them notrace explicitly. No functional change.
