Description of problem:
The machine check code in the Redhat update3 kernel, which is based on
the 2.4.21 stock kernel code has several shortcomings. The stock
kernel through 2.4.27 has undergone several changes that fixes several
problems including:

- Detailed decoding for the error status reported during machine checks.
- Proper handling of printks to report unrecoverable errors. (allowing
printks to get to the console etc.)

Attached is a patch against the RHAS3 update3 kernel that backports
the 2.4.27 machine check code.

Version-Release number of selected component (if applicable):
linux kernel version 2.4.21-20.ELsmp

How reproducible:
Sometimes

Steps to Reproduce:
1. Run on a machine that produces machine check exceptions.
2.
3.
