    Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
    
    Pull arm64 updates from Catalin Marinas:
     "Here are the main arm64 updates for 4.6.  There are some relatively
      intrusive changes to support KASLR, the reworking of the kernel
      virtual memory layout and initial page table creation.
    
      Summary:
    
       - Initial page table creation reworked to avoid breaking large block
         mappings (huge pages) into smaller ones.  The ARM architecture
         requires break-before-make in such cases to avoid TLB conflicts but
         that's not always possible on live page tables
    
       - Kernel virtual memory layout: the kernel image is no longer linked
         to the bottom of the linear mapping (PAGE_OFFSET) but at the bottom
         of the vmalloc space, allowing the kernel to be loaded (nearly)
         anywhere in physical RAM
    
       - Kernel ASLR: position independent kernel Image and modules being
         randomly mapped in the vmalloc space with the randomness is
         provided by UEFI (efi_get_random_bytes() patches merged via the
         arm64 tree, acked by Matt Fleming)
    
       - Implement relative exception tables for arm64, required by KASLR
         (initial code for ARCH_HAS_RELATIVE_EXTABLE added to lib/extable.c
         but actual x86 conversion to deferred to 4.7 because of the merge
         dependencies)
    
       - Support for the User Access Override feature of ARMv8.2: this
         allows uaccess functions (get_user etc.) to be implemented using
         LDTR/STTR instructions.  Such instructions, when run by the kernel,
         perform unprivileged accesses adding an extra level of protection.
         The set_fs() macro is used to "upgrade" such instruction to
         privileged accesses via the UAO bit
    
       - Half-precision floating point support (part of ARMv8.2)
    
       - Optimisations for CPUs with or without a hardware prefetcher (using
         run-time code patching)
    
       - copy_page performance improvement to deal with 128 bytes at a time
    
       - Sanity checks on the CPU capabilities (via CPUID) to prevent
         incompatible secondary CPUs from being brought up (e.g.  weird
         big.LITTLE configurations)
    
       - valid_user_regs() reworked for better sanity check of the
         sigcontext information (restored pstate information)
    
       - ACPI parking protocol implementation
    
       - CONFIG_DEBUG_RODATA enabled by default
    
       - VDSO code marked as read-only
    
       - DEBUG_PAGEALLOC support
    
       - ARCH_HAS_UBSAN_SANITIZE_ALL enabled
    
       - Erratum workaround Cavium ThunderX SoC
    
       - set_pte_at() fix for PROT_NONE mappings
    
       - Code clean-ups"
