* [PATCH] x86_64: Remove long obsolete CVSAndi Kleen2006-06-261-2/+0
| | | | | | | | Early development of x86-64 Linux was in CVS, but that hasn't been the case for a long time now. Remove the obsolete $Id$s. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] x86_64: fix single step handling for 32bit processesPeter Beutner2006-01-111-19/+7
| | | | | | | | | | | | | | | Be more careful with TF handling to fix some copy protection codes in wine patch originally for i386 by Linus, then ported to x86_64 by Andi Kleen see: [PATCH] x86_64: Some fixes for single step handling commit: be61bff789fe44bfb6d9282d8f7eccc860bdcfb6 But it was never applied to the ia32 emulation code which breaks some copy-protection schemes under wine when running on x86_64.

* [PATCH] i386: fix stack alignment for signal handlersMarkus F.X.J. Oberhumer2005-10-101-1/+5
| | | | | | | | | | | | | This fixes the setup of the alignment of the signal frame, so that all signal handlers are run with a properly aligned stack frame. The current code "over-aligns" the stack pointer so that the stack frame is effectively always mis-aligned by 4 bytes. But what we really want is that on function entry ((sp + 4) & 15) == 0, which matches what would happen if the stack were aligned before a "call" instruction. Signed-off-by: Markus F.X.J.

* [PATCH] x86_64: never block forced SIGSEGVRoland McGrath2005-06-231-7/+8
| | | | | | | | | | | | | | | | | | | This is the x86_64 version of the signal fix I just posted for i386. This problem was first noticed on PPC and has already been fixed there. But the exact same issue applies to other platforms in the same way. The signal blocking for sa_mask and the handled signal takes place after the handler setup. When the stack is bogus, the handler setup forces a SIGSEGV. But then this will be blocked, and returning to user mode will fault again and iterate. This patch fixes the problem by checking whether signal handler setup failed, and not doing the signal-blocking if so. This copies what was done in the ppc code. I think all architectures' signal handler setup code follows this pattern and needs the change.

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!
