* [PATCH] mutex subsystem, more debugging codeIngo Molnar2006-01-091-0/+19
| | | | | | | | more mutex debugging: check for held locks during memory freeing, task exit, enable sysrq printouts, etc. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Arjan van de Ven <arjan@infradead.org>
* [PATCH] drivers/char/sysrq.c: make two functions staticAdrian Bunk2005-11-091-2/+2
| | | | | | | | This patch makes two needlessly global functions static. Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] Update sysrq-B to use emergency_restart()Eric W. Biederman2005-07-261-1/+1
| | | | | | | | | | | | sysrq calls into the reboot path from an interrupt handler we can either push the code do into process context and call kernel_restart and get a clean reboot or we can simply reboot the machine, and increase our chances of actually rebooting. emergency_reboot() seems like the closest match to what we have previously done, and what we want.

* [PATCH] kdump: Use real pt_regs from exceptionAlexander Nyberg2005-06-251-1/+1
| | | | | | | | | | | | | | | | | | | | | Makes kexec_crashdump() take a pt_regs * as an argument. This allows to get exact register state at the point of the crash. If we come from direct panic assertion NULL will be passed and the current registers saved before crashdump. This hooks into two places: die(): check the conditions under which we will panic when calling do_exit and go there directly with the pt_regs that caused the fatal fault. die_nmi(): If we receive an NMI lockup while in the kernel use the pt_regs and go directly to crash_kexec(). We're probably nested up badly at this point so this might be the only chance to escape with proper information.

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!
