Alexander Nyberg	6e274d1443	[PATCH] kdump: Use real pt_regs from exception ... 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.

Eric W. Biederman	5234f5eb04	[PATCH] kexec: x86_64 kexec implementation ... This is the x86_64 implementation of machine kexec. 32bit compatibility support has been implemented, and machine_kexec has been enhanced to not care about the changing internal kernel paget table structures.
