* [PATCH] mark several functions __always_inlineIngo Molnar2006-01-14
| | | | | | | | | | | | | | | Arjan van de Ven <arjan@infradead.org> Mark a number of functions as 'must inline'. The functions affected by this patch need to be inlined because they use knowledge that their arguments are constant so that most of the function optimizes away. At this point this patch does not change behavior, it's for documentation only (and for future patches in the inline series) Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Arjan van de Ven <arjan@infradead.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] x86: fls() in asmStephen Hemminger2006-01-06
| | | | | | | | | There is a single instruction on i386 to find largest set bit; so it makes sense to use it (like we use bfs for ffs()). Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] x86: handle -Wsign-compare in bitopsDavid Howells2006-01-06
| | | | | | | | | Make i386's find_first_bit() use an unsigned integer as a counter to avoid getting warnings when -Wsign-compare is given. Signed-Off-By: David Howells <dhowells@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* x86: fix new find_first_bit()Linus Torvalds2005-07-29
| | | | | | | | | Some edge problems with the original C rewrite. Thanks go to Cal Peake, who pinpointed the breakage to the rewrite, and tested this fixed version. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] speed up on find_first_bit for i386 (let compiler do the work)Steven Rostedt2005-07-28
| | | | | | | | Avoid using "rep scas", just let the compiler select a sequence of regular instructions. Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

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!
