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
