applied them to tip/x86/crashdump, thanks Eduardo!

this branch btw. is an append-only non-rebasing tree that is not a 
moving target, you can access it via:

  http://people.redhat.com/mingo/tip.git/README

and then do:

  git checkout -b x86/crashdump tip/x86/crashdump

it has the following changes queued up currently:

Eduardo Habkost (8):
      x86 kdump: extract kdump-specific code from crash_nmi_callback()
      x86 kdump: move crashing_cpu assignment to nmi_shootdown_cpus()
      x86 kdump: create kdump_nmi_shootdown_cpus()
      x86 kdump: make kdump_nmi_callback() a function ptr on crash_nmi_callback()
      x86 kdump: make nmi_shootdown_cpus() non-static
      x86: move nmi_shootdown_cpus() to reboot.c
      x86: make nmi_shootdown_cpus() available on !SMP and !X86_LOCAL_APIC
      x86: disable IRQs before doing anything on nmi_shootdown_cpus()

Huang Ying (3):
      kexec/i386: remove PAGE_SIZE alignment from relocate_kernel
      kexec/i386: allocate page table pages dynamically
      kexec/i386: setup kexec page table in C

if you prefer less flux then you can send patches against that branch, 
we'll sort out interaction with other trees.

	Ingo
