x86, microcode, AMD: Rewrite patch application procedure (2012-08-17 14:17:42 +0200)
----------------------------------------------------------------
Per-family patches cache
This patch set adds code for caching all microcode patches which belong
to the current family on which we're running. We look up the patch
needed for each core from the cache at application time instead of
holding a single patch per-system.
Also, a bunch of fixes/cleanups precede the meat in the last 3.
Patchset has been tested on all families which are supported by the
microcode loader ( >= 0x10).

Hmmm... this isn't actually present on git.kernel.org, and 01/12 is
missing from your "v0" patchset on LKML (nevermind that a "v0"
designator screams "don't apply"...)

Hmm, that's actually the tag and it is there:

I tried this locally, here's what I did:

$ git fetch bp

So I think you need to fetch the tags with "git fetch --tags" - this is
why I had to fetch a second time above... I seem to remember this being
the case in other pull requests, btw.
Thanks.

Weird. I have never had to git fetch --tags before...

OK, sorted. Next complaint... please don't mix urgent (for the current
version) and non-urgent (for next) in the same pull request.
I have sorted it out, but it made things take a lot longer on my part.

So why did you have to fetch the tags this time?

Ok, urgent goes out as urgently as possible. Got it.

Thanks. I'd consider this whole deal done now :).
