Subject: xen/arm: Clean up identify processor call for secondary cpus
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~6600

xen/arm: Clean up identify processor call for secondary cpus

The smp_processor_id() is set at the beginning of start_secondary. We don't
need to compute ourself the offset of the cpu data.
