[PATCH] kdump: x86_64 kexec on panic
) From: Vivek Goyal <vgoyal@in.ibm.com> - Implementing the machine_crash_shutdown for x86_64 which will be called by crash_kexec (called in case of a panic, sysrq etc.). Here we do things similar to i386. Disable the interrupts, shootdown the cpus and shutdown LAPIC and IOAPIC. Changes in this version: - As the Eric's APIC initialization patches are reverted back, reintroducing LAPIC and IOAPIC shutdown. - Added some comments on CPU hotplug, modified code as suggested by Andi kleen.
