    Pull more arm64 updates from Will Deacon:
     "A small selection of further arm64 fixes and updates. Most of these
      are fixes that came in during the merge window, with the exception of
      the HAVE_MOVE_PMD mremap() speed-up which we discussed back in 2018
      and somehow forgot to enable upstream.
    
       - Improve performance of Spectre-v2 mitigation on Falkor CPUs (if
         you're lucky enough to have one)
    
       - Select HAVE_MOVE_PMD. This has been shown to improve mremap()
         performance, which is used heavily by the Android runtime GC, and
         it seems we forgot to enable this upstream back in 2018.
    
       - Ensure linker flags are consistent between LLVM and BFD
    
       - Fix stale comment in Spectre mitigation rework
    
       - Fix broken copyright header
    
       - Fix KASLR randomisation of the linear map
    
       - Prevent arm64-specific prctl()s from compat tasks (return -EINVAL)"
