CVS commit: src/sys/arch/x86/x86

[Andrew Doran <ad%netbsd.org@localhost>]

Module Name:    src
Committed By:   ad
Date:           Tue Nov 25 15:40:30 UTC 2008

Modified Files:
        src/sys/arch/x86/x86: tsc.c

Log Message:
A fix for failed TSC calibration with the message "ERROR: %lld cycle TSC
drift observed".

On i386, cpu_cc_skew was written out as two 32-bit words. If unlucky, the
boot processor could read the whole 64-bit value after only 32-bits of the
update were written back to main memory.
