[git pull] vfs.git compat and uaccess

[Al Viro <viro@ZenIV.linux.org.uk>]

	{get,put}_compat_sigset() series + assorted compat ioctl stuff +
more set_fs() elimination + a few more timespec64 conversions + several
removals of pointless access_ok() in places where it was followed only by
non-__ variants of primitives.

	One conflict (in drivers/staging/pi433); mainline side is purely
whitespace stuff (from commit 69af5d92da20 "Staging: pi433: Fix the position
of brace after if").

The following changes since commit 2bd6bf03f4c1c59381d62c61d03f6cc3fe71f66e:
