Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
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" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (47 commits) arm64: compat: Remove incorrect comment in compat_siginfo arm64: Fix section mismatch on alloc_init_p[mu]d() arm64: Avoid breakage caused by .altmacro in fpsimd save/restore macros arm64: mm: use *_sect to check for section maps arm64: drop unnecessary cache+tlb maintenance arm64:mm: free the useless initial page table arm64: Enable CPU_IDLE in defconfig arm64: kernel: remove ARM64_CPU_SUSPEND config option arm64: make sys_call_table const arm64: Remove asm/syscalls.h arm64: Implement the compat_sys_call_table in C syscalls: Declare sys_*stat64 prototypes if __ARCH_WANT_(COMPAT_)STAT64 compat: Declare compat_sys_sigpending and compat_sys_sigprocmask prototypes arm64: uapi: expose our struct ucontext to the uapi headers smp, ARM64: Kill SMP single function call interrupt arm64: Emulate SETEND for AArch32 tasks arm64: Consolidate hotplug notifier for instruction emulation arm64: Track system support for mixed endian EL0 arm64: implement generic IOMMU configuration arm64: Combine coherent and non-coherent swiotlb dma_ops ...
