[PATCH v4] linux/uio.h: cleanup for userspace

[Mike Frysinger]

Hide iov_shorten() behind __KERNEL__ since it's a prototype only.  Use the
__inline__ form for iov_length() since it's usable by userspace.

Signed-off-by: Mike Frysinger <vapier@xxxxxxxxxx>
---
v4
	- hide all funcs behind __KERNEL__
v3
	- keep all __KERNEL__ stuff in one place
v2
	- drop inline conversion stuff
