Currently I can't boot up secondary CPUs on qcom platforms when I
compile the kernel for THUMB2 mode. This is because we always enter
the kernel in ARM mode regardless of what mode the kernel is compiled
for. This patchset adds a small wrapper to secondary_startup() called
secondary_startup_arm() that allows us to switch into THUMB2 mode if
we need to. If the kernel is compiled for ARM mode it shouldn't have
any effect.

ARM: Add a secondary_startup that assumes ARM mode
ARM: qcom: Use secondary_startup_arm()
