Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip! 2005-04-16 15:20:36 -07:00			`/* Never include this file directly. Include <linux/compiler.h> instead. */`

[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.
