#     
#     Pull RISC-V fixes from Palmer Dabbelt:
#      "This contains a pair of bug fixes that I'd like to include in 5.0:
#     
#        - A fix to disambiguate swap from invalid PTEs, which fixes an error
#          when trying to unmap PROT_NONE pages.
#     
#        - A revert to an optimization of the size of flat binaries. This is
#          really a workaround to prevent breaking existing boot flows, but
#          since the change was introduced as part of the 5.0 merge window I'd
#          like to have the fix in before 5.0 so we can avoid a regression for
#          any proper releases.
#     
#       With these I hope we're out of patches for 5.0 in RISC-V land"
