* [PATCH] x86_64: Align and pad x86_64 GDT on page boundaryRavikiran G Thirumalai2006-01-111-5/+8
| | | | | | | | | | | | | | | | This patch is on the same lines as Zachary Amsden's i386 GDT page alignemnt patch in -mm, but for x86_64. Patch to align and pad x86_64 GDT on page boundries. [AK: some minor cleanups and fixed incorrect TLS initialization in CPU init.] Signed-off-by: Nippun Goel <nippung@calsoftinc.com> Signed-off-by: Ravikiran Thirumalai <kiran@scalex86.org> Signed-off-by: Shai Fultheim <shai@scalex86.org> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] x86_64: Move int 3 handler to debug stack and allow to increase it.Jan Beulich2006-01-111-0/+5
| | | | | | | | | | | | | | | | | | This - switches the INT3 handler to run on an IST stack (to cope with breakpoints set by a kernel debugger on places where the kernel's %gs base hasn't been set up, yet); the IST stack used is shared with the INT1 handler's [AK: this also allows setting a kprobe on the interrupt/exception entry points] - allows nesting of INT1/INT3 handlers so that one can, with a kernel debugger, debug (at least) the user-mode portions of the INT1/INT3 handling; the nesting isn't actively enabled here since a kernel- debugger-free kernel doesn't need it Signed-Off-By: Jan Beulich <jbeulich@novell.com> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | interrupt sources Here's a patch that builds on Natalie Protasevich's IRQ compression patch and tries to work for MPS boots as well as ACPI. It is meant for a 4-node IBM x460 NUMA box, which was dying because it had interrupt pins with GSI numbers > NR_IRQS and thus overflowed irq_desc. The problem is that this system has 270 GSIs (which are 1:1 mapped with I/O APIC RTEs) and an 8-node box would have 540. This is much bigger than NR_IRQS (224 for both i386 and x86_64). Also, there aren't enough vectors to go around. There are about 190 usable vectors, not counting the reserved ones and the unused vectors at 0x20 to 0x2F. So, my patch attempts to compress the GSI range and share vectors by sharing IRQs.

* Linux-2.6.12-rc2Linus Torvalds2005-04-161-0/+217
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!
