Subject: linux-next: manual merge of the cpuidle-cons tree with the arm-soc
 tree

Hi Rob,

Today's linux-next merge of the cpuidle-cons tree got a conflict in
arch/arm/mach-at91/cpuidle.c between commit 00482a4078f4 ("ARM: at91:
implement the standby function for pm/cpuidle") from the arm-soc tree and
commit 7a1f6e72dce1 ("ARM: at91: Consolidate time keeping and irq
enable") from the cpuidle-cons tree.

I fixed it up (I think - see below) and can carry the fix as necessary.
