Hi all,

Today's linux-next merge of the tegra tree got a conflict in
arch/arm/mach-tegra/headsmp.S between commit bc4f1bdabc89 ("ARM:
coresight: common definition for (OS) Lock Access Register key value")
from the arm-perf tree and commit 2a3eb5bc45bd ("ARM: tegra: make device
can run on UP") from the tegra tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
