Merge tag 'arm-soc/for-4.3/soc' of http://github.com/broadcom/stblinux into next/cleanup
Merge "Broadcom SoC changes for 4.3 (part 1)" from Florian Fainelli: This pull request contains two fixes for the Broadcom BCM63xx SMP code: - Sudeep removes an invalid use of cpu_logical_map() which turned to be a no-op since we always boot from physical CPU 0 = logical CPU 0 - Florian removes the custom secondary_startup function and replaces it with the generic one * tag 'arm-soc/for-4.3/soc' of http://github.com/broadcom/stblinux: ARM: BCM63xx: Remove custom secondary_startup function ARM: BCM63xx: fix parameter to of_get_cpu_node in bcm63138_smp_boot_secondary Signed-off-by: Olof Johansson <olof@lixom.net>
