* [PATCH] x86: fls() in asmStephen Hemminger2006-01-061-5/+17
| | | | | | | | | 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 Howells2006-01-061-2/+2
| | | | | | | | | 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 Torvalds2005-07-291-7/+6
| | | | | | | | | 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 Rostedt2005-07-281-30/+24
| | | | | | | | 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!
