kexec_file() support was recently added for RISC-V [1], which triggered
a handful of build issues on rv32. These all seemed pretty minor, but
it looks like this is the only 32-bit platform that has attempted to
build the kexec IMA support before so I'm not sure if there's something
more complicated going on that I'm missing (I haven't tested any of
this).
The rv64 support was just merged into kernel.org/riscv/linux/for-next as
83a7a614ce58 ("riscv: kexec: add kexec_file_load() support"). I've put
these on top of the pre-merged version at
kernel.org/palmer/linux/riscv-kexec_file-rv32 if that helps anyone.
