[Xen-devel] [PATCH v2] xen/arm: Clean up identify processor call for secondary cpus

[Julien Grall <julien.grall@xxxxxxxxxx>]

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.

    Changes in v2:
        - Initalize the current cpu data with boot cpu data
