#     Pull RISC-V fixes from Palmer Dabbelt:
#      "This is obviously not ideal, particularly for something this late in
#       the cycle.
#     
#       Unfortunately we found some uABI issues in the vector support while
#       reviewing the GDB port, which has triggered a revert -- probably a
#       good sign we should have reviewed GDB before merging this, I guess I
#       just dropped the ball because I was so worried about the context
#       extension and libc suff I forgot. Hence the late revert.
#     
#       There's some risk here as we're still exposing the vector context for
#       signal handlers, but changing that would have meant reverting all of
#       the vector support. The issues we've found so far have been fixed
#       already and they weren't absolute showstoppers, so we're essentially
#       just playing it safe by holding ptrace support for another release (or
#       until we get through a proper userspace code review).
#     
#       Summary:
#     
#        - The vector ucontext extension has been extended with vlenb
#     
#        - The vector registers ELF core dump note type has been changed to
#          avoid aliasing with the CSR type used in embedded systems
#     
#        - Support for accessing vector registers via ptrace() has been
#          reverted
#     
#        - Another build fix for the ISA spec changes around Zifencei/Zicsr
#          that manifests on some systems built with binutils-2.37 and
#          gcc-11.2"
