x86: ucode-amd: Don't warn when no ucode is available for a CPU revision
This patch originally comes from the Linus mainline kernel (2.6.33),
find below the patch details:
From: Andreas Herrmann <herrmann.der.user@googlemail.com>
There is no point in warning when there is no ucode available
for a specific CPU revision. Currently the container-file, which
provides the AMD ucode patches for OS load, contains only a few
ucode patches.
It's already clearly indicated by the printed patch_level
whenever new ucode was available and an update happened. So the
warning message is of no help but rather annoying on systems
with many CPUs.
