[PATCH] cpumask: bitmap inlining and optimizations
From: Paul Jackson <pj@sgi.com>
These bitmap improvements make it a suitable basis for fully supporting
cpumask_t and nodemask_t. Inline macros with compile-time checks enable
generating tight code on both small and large systems (large meaning cpumask_t
requires more than one unsigned long's worth of bits).
The existing bitmap_<op> macros in lib/bitmap.c are renamed to __bitmap_<op>,
and wrappers for each bitmap_<op> are exposed in include/linux/bitmap.h
This patch _includes_ Bill Irwins rewrite of the bitmap_shift operators to not
require a fixed length intermediate bitmap.
Improved comments list each available operator for easy browsing.
