Merge tag 'arm64-for-linus' of git://git./linux/kernel/git/cmarinas/linux-aarch64

Pull arm64 update from Catalin Marinas:
 "Main features:

   - Versatile Express SoC (model) support - DT files and Kconfig
     entries (there are no arch/arm64/mach-* directories).  The bulk of
     the code has already been moved to drivers/ as part of the ARM SoC
     clean-up.

   - Basic multi-cluster support (CPU logical map initialised from the
     DT)

   - Simple earlyprintk support for UART 8250/16550 and FastModel
     console output

   - Optimised kernel library bitops and string functions.

   - Automatic initialisation of the irqchip and clocks via DT"
