Hmm, actually the automation on patchwork is complaining a bunch about
the series, but I think that's mostly false positives except for this
patch. The nommu defconfigs are prob the easiest way to reproduce this:
  /build/tmp.QPMRM3oUNu/arch/riscv/kernel/vendor_extensions.c:41:55: error: 'struct riscv_isa_vendor_ext_data_list' has no member named 'vendor_bitmap'
  /build/tmp.QPMRM3oUNu/arch/riscv/kernel/vendor_extensions.c:42:60: error: 'struct riscv_isa_vendor_ext_data_list' has no member named 'per_hart_vendor_bitmap'; did you mean 'per_hart_isa_bitmap'?
  /build/tmp.QPMRM3oUNu/arch/riscv/kernel/vendor_extensions.c:43:60: error: 'struct riscv_isa_vendor_ext_data_list' has no member named 'bitmap_size'

Cheers,
Conor.
