Subject: [PATCH 0/4] Enable deferred error interrupts

Newer AMD processors can generate deferred errors and can be configured
to generate APIC interrupts on such events.

This patchset introduces a new interrupt handler for deferred errors and
configures the HW if the feature is present.

Patch1: Defines SUCCOR cpuid bit. This indicates prescence of features
	such as data poisoning and deferred error interrupts in hardware.
Patch2: Implement the interrupt handler.
	- setup vector number, build the interrupt and implement handler
	  function in this patch.
Patch3, Patch 4: Cleanups in the code. No functional changes are introduced.

Aravind Gopalakrishnan (4):
  x86/mce: Define 'SUCCOR' cpuid bit
  x86/mce/amd: Introduce deferred error interrupt handler
  x86, irq: Cleanup ordering of vector numbers
  x86/mce/amd: Rename setup_APIC_mce
