PATCH 1/1 Fix __check_region deprecation

Linus, please apply.

Kills that stupid deprecated warning in kernel/ksyms.c, and makes others simpler.

Name: Fix overzealous check_region deprecation
Author: Rusty Russell
Status: Trivial

D: 1) We export __check_region, so making it __deprecated gives a spurious
D:    warning in kernel/ksyms.c.
D: 2) Other warnings refer to __check_region rather than check_region,
D:    which has confused some people.

D:
D: Make check_region an inline, not a macro, and deprecate *that*.
