commit f4000cd99750065d5177555c0a805c97174d1b9f
Merge: 2ec4584 7503712

    Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
    
    Pull arm64 updates from Catalin Marinas:
    
     - struct thread_info moved off-stack (also touching
       include/linux/thread_info.h and include/linux/restart_block.h)
    
     - cpus_have_cap() reworked to avoid __builtin_constant_p() for static
       key use (also touching drivers/irqchip/irq-gic-v3.c)
    
     - uprobes support (currently only for native 64-bit tasks)
    
     - Emulation of kernel Privileged Access Never (PAN) using TTBR0_EL1
       switching to a reserved page table
    
     - CPU capacity information passing via DT or sysfs (used by the
       scheduler)
    
     - support for systems without FP/SIMD (IOW, kernel avoids touching
       these registers; there is no soft-float ABI, nor kernel emulation for
       AArch64 FP/SIMD)
    
     - handling of hardware watchpoint with unaligned addresses, varied
       lengths and offsets from base
    
     - use of the page table contiguous hint for kernel mappings
    
     - hugetlb fixes for sizes involving the contiguous hint
    
     - remove unnecessary I-cache invalidation in flush_cache_range()
    
     - CNTHCTL_EL2 access fix for CPUs with VHE support (ARMv8.1)
    
     - boot-time checks for writable+executable kernel mappings
    
     - simplify asm/opcodes.h and avoid including the 32-bit ARM counterpart
       and make the arm64 kernel headers self-consistent (Xen headers patch
       merged separately)
    
     - Workaround for broken .inst support in certain binutils versions
