[Xen-devel] [PATCH v2 1/6] xen/arm32: proc-v7.S: Rename v7_init and ACTLR_V7_SMP

[Julien Grall <julien.grall@xxxxxxxxxx>]

The function v7_init and the define ACTLR_V7_SMP are Cortex A15/A7
specific.

To avoid misuse when new ARMv7 processors will be supported, create one
label per processor type and rename ACTLR_V7_SMP in ACTRL_CAXX_SMP
