x86: consolidate header guards This patch is the result of an automatic script that consolidates the format of all the headers in include/asm-x86/. The format: 1. No leading underscore. Names with leading underscores are reserved. 2. Pathname components are separated by two underscores. So we can distinguish between mm_types.h and mm/types.h. 3. Everything except letters and numbers are turned into single underscores. Signed-off-by: Vegard Nossum <vegard.nossum@gmail.com>

[PATCH] Add emergency_restart() When the kernel is working well and we want to restart cleanly kernel_restart is the function to use. But in many instances the kernel wants to reboot when thing are expected to be working very badly such as from panic or a software watchdog handler. This patch adds the function emergency_restart() so that callers can be clear what semantics they expect when calling restart. emergency_restart() is expected to be callable from interrupt context and possibly reliable in even more trying circumstances. This is an initial generic implementation for all architectures. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

x86: EFI runtime service support: EFI runtime services This patch adds support for several EFI runtime services for EFI x86_64 system. The EFI support for emergency_restart is added.

x86: reboot_{32|64}.c unification reboot_{32|64}.c unification patch. This patch unifies the code from the reboot_32.c and reboot_64.c files. It has been tested in computers with X86_32 and X86_64 kernels and it looks like all reboot modes work fine (EFI restart system hasn't been tested yet). Probably I made some mistakes (like I usually do) so I hope we can identify and fix them soon.
