#     
#     Pull RISC-V fixes from Palmer Dabbelt:
#      "This contains a few patches that fix various issues in the RISC-V
#       port:
#     
#        - enable printk timestamps in the RISC-V defconfig.
#     
#        - a whitespace fix to "struct pt_regs".
#     
#        - add a "vdso_install" target for RISC-V.
#     
#        - a pair of build fixes: one to fix a typo in our makefile, and one
#          to clean up some warnings.
#     
#       There will probably be more patches from us for 4.20, but I don't have
#       anything that's ready to go right now so I'm going to hold off a bit.
#     
#       Right now the only concrete thing I know I want to make sure gets
#       sorted out is our 32-bit stat interface, which I don't want sitting in
#       limbo for another cycle as we have to get RV32I glibc sone"
