[PATCH] Make __always_inline actually force always inlining

This patch is the first in a series that tries to optimize the kernel in terms
of size (and thus cache behavior, both cpu and pagecache).

This first patch changes __always_inline to be a forced inline instead of the
"regular" inline it was on everything except alpha.  This forced inline
matches the intention of the define better as a matter of documentation.
There is no change in behavior by this patch, since "inline" currently is
mapped to a forced inline anyway.
