[PATCH v4 01/18] ARM64: Move the init of cpu_logical_map(0) before unflatten_device_tree()

From: Hanjun Guo
Date: Fri Sep 12 2014 - 10:00:55 EST


It always make sense to initialize CPU0's logical map entry from the
hardware values, so move the initialization of cpu_logical_map(0)
before unflatten_device_tree() which is needed by ACPI code later.
