edac, mce: Fix wrong mask and macro usage

2010-05-12T21:57:05+00:00

commit 35d824b28fc5544d1eb7c1e3db15a1740df8ec4b upstream.

Correct two mishaps which prevented reporting error type (CECC vs UECC)
and extended error description.

x86: EDAC: carve out AMD MCE decoding logic

2009-10-02T13:42:19+00:00

This converts the MCE decoding logic into a standalone config
option which can be built-in or a module, the first one being the
default for MCEs happening early on in the boot process.

This, beyond being separated in a cleaner way, also saves RAM by
making the decoding logic modular.

x86: EDAC: MCE: Fix MCE decoding callback logic

2009-10-02T13:42:18+00:00

Make decoding of MCEs happen only on AMD hardware by registering a
non-default callback only on CPU families which support it.

While looking at the interaction of decode_mce() with the other MCE
code i also noticed a few other things and made the following
cleanups/fixes:

 - Fixed the mce_decode() weak alias - a weak alias is really not
   good here, it should be a proper callback. A weak alias will be
   overriden if a piece of code is built into the kernel - not
   good, obviously.

 - The patch initializes the callback on AMD family 10h and 11h.

 - Added the more correct fallback printk of:

	No support for human readable MCE decoding on this CPU type.
	Transcribe the message and run it through 'mcelog --ascii' to decode.

   On CPUs that dont have a decoder.

 - Made the surrounding code more readable.

Note that the callback allows us to have a default fallback -
without having to check the CPU versions during the printout
itself. When an EDAC module registers itself, it can install the
decode-print function.

(there's no unregister needed as this is core code.)

version -v2 by Borislav Petkov:

 - add K8 to the set of supported CPUs

 - always build in edac_mce_amd since we use an early_initcall now

 - fix checkpatch warnings
