    Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
    
    Pull arm64 updates from Will Deacon:
    
     - Support for new architectural features introduced in ARMv8.1:
       * Privileged Access Never (PAN) to catch user pointer dereferences in
         the kernel
       * Large System Extension (LSE) for building scalable atomics and locks
         (depends on locking/arch-atomic from tip, which is included here)
       * Hardware Dirty Bit Management (DBM) for updating clean PTEs
         automatically
    
     - Move our PSCI implementation out into drivers/firmware/, where it can
       be shared with arch/arm/. RMK has also pulled this component branch
       and has additional patches moving arch/arm/ over. MAINTAINERS is
       updated accordingly.
    
     - Better BUG implementation based on the BRK instruction for trapping
    
     - Leaf TLB invalidation for unmapping user pages
    
     - Support for PROBE_ONLY PCI configurations
    
     - Various cleanups and non-critical fixes, including:
       * Always flush FP/SIMD state over exec()
       * Restrict memblock additions based on range of linear mapping
       * Ensure *(LIST_POISON) generates a fatal fault
       * Context-tracking syscall return no longer corrupts return value when
         not forced on.
       * Alternatives patching synchronisation/stability improvements
       * Signed sub-word cmpxchg compare fix (tickled by HAVE_CMPXCHG_LOCAL)
       * Force SMP=y
       * Hide direct DCC access from userspace
       * Fix EFI stub memory allocation when DRAM starts at 0x0
    
    * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (92 commits)
