#     Merge tag 'riscv-for-linus-5.7-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
#     
#     Pull RISC-V fixes from Palmer Dabbelt:
#      "A handful of build fixes, all found by Huawei's autobuilder.
#     
#       None of these patches should have any functional impact on kernels
#       that build, and they're mostly related to various features
#       intermingling with !MMU.
#     
#       While some of these might be better hoisted to generic code, it seems
#       better to have the simple fixes in the meanwhile.
#     
#       As far as I know these are the only outstanding patches for 5.7"
