SubjectRe: [GIT PULL] A minor amd64_edac fix for 3.13
From
[ This was in my spam collection. I don't quite know why, but it might
signify problems with your email setup. Quite often, when gmail is
unhappy about kernel developer emails, it's been because their email
provider ends up doing something odd.

But the headers actually have "spf=pass" and "dkim=pass", so it's
nothing obvious. ]

That said, I don't much like the patch either. The "fixed' version
looks worse than the original. If it's an unsigned type, no extra code
will be generated, and if it's a signed type, it's correct. In either
way, the code looks good, and the range test means that people reading
it don't even need to worry about whether the type is signed or not.

If this patch was written because of some f*cking broken compiler
warning, then just tell the compiler to shut the hell up about it.
This is a clear example of where compiler warnings are actually making
things worse.
