* [PATCH] x86_64: Switch to the interrupt stack when running a softirq in ↵Andi Kleen2005-07-29
| | | | | | | | | | | | | local_bh_enable() This avoids some potential stack overflows with very deep softirq callchains. i386 does this too. TOADD CFI annotation Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] x86_64: Small assembly improvementsAndi Kleen2005-07-29
| | | | | | | | | | | | Save a byte here and there. Ultimatively useless, but these things always catch my eyes when reading the code so just fix them for now. Also I got at least one patch fixing of them already, which gives a good excuse.

* [PATCH] x86_64: Fix a small missing schedule raceAndi Kleen2005-04-16
| | | | | | | | | | | | Could lead to a lost reschedule event when the process already rescheduled on exception exit, and needs it again while still being in the kernel. Unlikely case though. Also remove one redundant cli in another entry.S path. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] x86_64: Regularize exception stack handlingAndi Kleen2005-04-16
| | | | | | | | | | | | This fixes various issues in the return path for "paranoid" handlers (= running on a private exception stack that act like NMIs). Generalize previous hack to switch back to process stack for scheduling/signal handling purposes.

* [PATCH] x86_64: Call do_notify_resume unconditionally in entry.SAndi Kleen2005-04-16
| | | | | | | | | | | | | This removes some unnecessary code in the assembly files. Matches i386 behaviour. In addition don't clear the work check mask after work has been done. This fixes some theoretical signal/other event losses. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.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!
