Yes, this is the one I meant.
Thanks.

Sorry about that.
That line should be in [patch 2/2] and I mistakenly committed it as part 
of this patch.

It didn't show up on my builds as I had build tested after applying both 
patches.

But there is a different problem now.
The second patch won't apply cleanly on top of your fix-

error: while searching for:
}

/* keeping mce_severity_amd in sync with AMD error scope heirarchy table */
static int mce_severity_amd(struct mce *m, enum context ctx)
{
        enum context ctx = error_context(m);
        /* Processor Context Corrupt, no need to fumble too much, die! */

error: patch failed: arch/x86/kernel/cpu/mcheck/mce-severity.c:187

I think the clean way to fix this would be to move the line to [patch 2/2].
Besides, we would need a new patch 2 anyway as the patch application 
would fail due to changes to the comment line.

Shall I do that and resend?

Thanks,
