    Pull arm64 updates from Catalin Marinas:
     "arm64 updates for 3.20:
    
       - reimplementation of the virtual remapping of UEFI Runtime Services
         in a way that is stable across kexec
       - emulation of the "setend" instruction for 32-bit tasks (user
         endianness switching trapped in the kernel, SCTLR_EL1.E0E bit set
         accordingly)
       - compat_sys_call_table implemented in C (from asm) and made it a
         constant array together with sys_call_table
       - export CPU cache information via /sys (like other architectures)
       - DMA API implementation clean-up in preparation for IOMMU support
       - macros clean-up for KVM
       - dropped some unnecessary cache+tlb maintenance
       - CONFIG_ARM64_CPU_SUSPEND clean-up
       - defconfig update (CPU_IDLE)
    
      The EFI changes going via the arm64 tree have been acked by Matt
      Fleming.  There is also a patch adding sys_*stat64 prototypes to
      include/linux/syscalls.h, acked by Andrew Morton"
