[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.
