Subject: linux-next: manual merge of the akpm tree with Linus' tree
Date: Tue, 8 Nov 2011 14:24:32 +1100
Message-ID: <20111108142432.c27531efb6b6f8518e2555a0@canb.auug.org.au> (raw)

Hi Andrew,

Today's linux-next merge of the akpm tree got a conflict in
drivers/idle/intel_idle.c between commit 46bcfad7a819 ("cpuidle:
Single/Global registration of idle states") from Linus' tree and commit
"intel_idle: fix API misuse" from the akpm tree.

The former moved the code modified by the latter.  I fixed it up (see
below0 and can carry the fix as necessary.

Cheers,
Stephen Rothwell                    sfr@canb.auug.org.au
