[Qemu-devel] [PATCH for-2.13 v2 1/5] arm: always start from first_cpu when registering loader cpu reset callback

[Igor Mammedov <imammedo@redhat.com>]

if arm_load_kernel() were passed non first_cpu, QEMU would end up
with partially set do_cpu_reset() callback leaving some CPUs without it.

Make sure that do_cpu_reset() is registered for all CPUs by enumerating
CPUs from first_cpu.
