Subject: linux-next: manual merge of the tip tree with the pm tree
Date: Mon, 19 Aug 2013 14:09:21 +1000 [thread overview]
Message-ID: <20130819140921.7c43b398fdc9eb6e53b631ab@canb.auug.org.au> (raw)
[-- Attachment #1: Type: text/plain, Size: 1941 bytes --]
Hi all,
Today's linux-next merge of the tip tree got a conflict in
arch/x86/include/asm/processor.h between commit 61c63e5ed3b9 ("cpufreq:
Remove unused APERF/MPERF support") from the pm tree and commit
96e39ac0e9d1 ("x86: Introduce hypervisor_cpuid_base()") from the tip tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Cheers,
