Subject: [PATCH] SH: Convert out[bwl] macros to inline functions

From: Corey Minyard <cminyard@...sta.com>

The macros just called BUG(), but that results in unused variable
warnings all over the place, like in the IPMI driver.  The build
regression emails were annoying me, so here's the fix.  I have
not even compile tested this, but it's rather obvious.
