[V3 PATCH 0/9] x86, NMI: give NMI handler a face-lift

From: Don Zickus
Date: Tue Nov 30 2010 - 17:30:09 EST


Restructuring the nmi handler to be more readable and simpler.

This is just laying the ground work for future improvements in this area.

I also left out one of Huang's patch until we figure out how we are going
to proceed with a new notifier.

Tested 32-bit and 64-bit on AMD and Intel machines.

V3: rebased on top of removal of nmi watchdog
add a couple more watchdog patches from my queue

V2: add a patch to kill DIE_NMI_IPI and add in priorities

Cheers,
Don

Don Zickus (5):
x86, NMI: Remove DIE_NMI_IPI and add priorties to handlers
x86: only call smp_processor_id in non-preempt cases
panic: ratelimit panic messages
watchdog: touch_nmi_watchdog should only touch local cpu not every
one

Dongdong Deng (1):
x86: Avoid calling arch_trigger_all_cpu_backtrace() at the same time

Huang Ying (3):
x86, NMI: Add NMI symbol constants and rename memory parity to PCI
SERR
x86, NMI: Add touch_nmi_watchdog to io_check_error delay
x86, NMI: Rewrite NMI handler
x86, NMI: Allow NMI reason io port (0x61) to be processed on any CPU
