    Linus Torvalds authored
    Pull arm64 updates from Catalin Marinas:
    
     - Kexec support for arm64
    
     - Kprobes support
    
     - Expose MIDR_EL1 and REVIDR_EL1 CPU identification registers to sysfs
    
     - Trapping of user space cache maintenance operations and emulation in
       the kernel (CPU errata workaround)
    
     - Clean-up of the early page tables creation (kernel linear mapping,
       EFI run-time maps) to avoid splitting larger blocks (e.g.  pmds) into
       smaller ones (e.g.  ptes)
    
     - VDSO support for CLOCK_MONOTONIC_RAW in clock_gettime()
    
     - ARCH_HAS_KCOV enabled for arm64
    
     - Optimise IP checksum helpers
    
     - SWIOTLB optimisation to only allocate/initialise the buffer if the
       available RAM is beyond the 32-bit mask
    
     - Properly handle the "nosmp" command line argument
    
     - Fix for the initialisation of the CPU debug state during early boot
    
     - vdso-offsets.h build dependency workaround
    
     - Build fix when RANDOMIZE_BASE is enabled with MODULES off
