Subject[PATCH V2 0/3] Updates to mce_amd_inj module
Date
This patchset is mostly a resend of earlier patches which got acceptance
into maintainer's tree but did not make it into upstream.
Original versions of patches 2 and 3 of this patchset-
a. http://marc.info/?l=linux-edac&m=143327679901253&w=2
b. http://marc.info/?l=linux-edac&m=143392472509250&w=2

Changes from original versions-
Patch 2: Earlier version did not include the update to README file.
That was because README attribute was introduced in separate
patch (http://marc.info/?l=linux-edac&m=143327679301249&w=2)
But subsequently, only parts of it made it upstream.

Patch 3: NBCFG register offset definition exists already in
drivers/edac/amd64_edac.h which was included in earlier version.
But any dependency with drivers/edac/ was removed when the file
moved to arch/x86/ras. So, I have redefined it here.
I can move it to a different place if required.

With changes to the location of the module, I am adapting the patches
on top of latest tip.

Patch 1: Abort write file operation on invalid input
Patch 2: Extend flags attribute to accept values of 'df', 'th'.
These values will be used to trigger deferred error/threshold
error apic interrupts respectively.
Patch 3: Modify injection mechanism for bank 4 errors. Since they are
logged or reported only on NBC, we make sure that we inject on
the correct core here.

Changes from V1 (per Boris' comments)
- Instead of ignoring unwanted characters, return early on wrong input
from user as this way, we can save a copy from user input for bad values.
- With above change, modified patch title and commit message a bit.
- Use 2 letter strings to indicate error injection for Deferred/Threshold
error interrupts too.

Aravind Gopalakrishnan (3):
RAS, mce_amd_inj: Return early on invalid input
RAS, mce_amd_inj: Add capability to trigger apic interrupts
RAS, mce_amd_inj: Inject errors on NBC for bank 4 errors
