Subject: linux-next: manual merge of the arm tree with the arm-current tree

Hi Russell,

Today's linux-next merge of the arm tree got a conflict in
arch/arm/mach-at91/include/mach/system.h between commit
5c189208b606a85b4e97109af70d59f10a42fdfd ("ARM: 6436/1: AT91: Fix
power-saving in idle-mode on 926T processors") from the arm-current tree
and commit cb809b1a5ebffca8cf0314b788919989e8e4ab5f ("AT91: fix use of
clock disable on idle for AT91x40 devices") from the arm tree.

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