From patch one onwards for rv32_defconfig:
  /tmp/tmp.TRw8gWHZCe/arch/riscv/include/asm/pgtable.h:636:9: error: call to undeclared function 'riscv_has_extension_unlikely'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
  /tmp/tmp.TRw8gWHZCe/include/linux/signal.h:97:11: warning: array index 3 is past the end of the array (that has type 'unsigned long[2]') [-Warray-bounds]

There seem to be quite a few of these -Warray-bounds issues, all in
code included from signal.h. Could you please do an rv32 build and fix
up these build issues?

Thanks,
Conor.
