[PATCH 0/3] Use generic helper scu_power_mode()

[Bastian Hecht]

Reposted to include the arch/arm mailing list.

The shmobile series implements its own code for setting the SCU power
register of the ARM MPCore. It uses 32-bit wide access and thus needs
locking as multiple CPUs might access it simultaneously for change. There is
already a small helper function that avoids the overhead by using 8-bit
wide access: As every CPU only accesses its own field we can drop the
lock and use it.

  ARM: shmobile: emev2: Replace modify_scu_cpu_psr with scu_power_mode
  ARM: shmobile: sh73a0: Replace modify_scu_cpu_psr with scu_power_mode
  ARM: shmobile: r8a7779: Replace modify_scu_cpu_psr with
    scu_power_mode
