This patch-set factors out the thermal throttle processing code
from i386 and x86_64 into a separate file (therm_throt.c).
This allows consistent reporting of CPU thermal throttle events.
Furthermore, a counter is added to /sys that keeps track of the
number of thermal events, such that the user knows how bad the
thermal problem might be (since the logging to syslog and mcelog
is rate limited).
Tested on 32bit and 64bit Intel P4 Xeons.
Differences from last cut:
- No more #ifdef CONFIG_X86_64.. sorry Andi :). x86_64 specific
code is in arch/x86_64/kernel/mce.c
- Commented the need/use for time_before64/time_after64.
(I addressed Andi Kleen's concern about these macros in a
followup from last attempt, but never got a response.)
- More comments in therm_throt.c and individual patch descriptions
