x86, mce, severity: Extend the the mce_severity mechanism to handle UCNA/DEFERRED error

2014-11-19T18:55:43+00:00

Until now, the mce_severity mechanism can only identify the severity
of UCNA error as MCE_KEEP_SEVERITY. Meanwhile, it is not able to filter
out DEFERRED error for AMD platform.

This patch extends the mce_severity mechanism for handling
UCNA/DEFERRED error. In order to do this, the patch introduces a new
severity level - MCE_UCNA/DEFERRED_SEVERITY.

In addition, mce_severity is specific to machine check exception,
and it will check MCIP/EIPV/RIPV bits. In order to use mce_severity
mechanism in non-exception context, the patch also introduces a new
argument (is_excp) for mce_severity. `is_excp' is used to explicitly
specify the calling context of mce_severity.

EDAC, MCE, AMD: Remove unneeded exports

2013-01-22T21:40:03+00:00

Initially, those strings describing different parts of an MCE message
were shared with amd64_edac and were therefore exported to modules.
However, all except pp_msgs are used only in one place right now so hide
them and make them static.

No functionality change.

EDAC, MCE, AMD: Make MC2 decoding per-family

2013-01-22T21:39:54+00:00

Currently only AMD Family 15h processors have special handling for MC2
errors. Since upcoming Family 16h will also need unique handling, let's
make MC2 handling part of amd_decoder_ops.

MCE, AMD: Remove functional unit references

2012-11-28T10:55:44+00:00

Having the functional unit names in each bank decode is only misleading
as this code supports multiple families and there's no guarantee the
mapping between FUs and MCE banks will stay the same.

And also, knowing the functional unit name doesn't help much since you
end up looking at the respective BKDG anyway.

So drop all FU references and use the MC bank numbers instead.

x86/bitops: Move BIT_64() for a wider use

Needed for shifting 64-bit values on 32-bit, like MSR values,
for example.
