[PATCH 0/5] sparsemem support for RISC-V

Hi Everyone,

This patchset is intended to implement sparsemem on RISC-V.
The first few patches are introducing a common helper used by the
sparesmem implementation in other architectures and the final
patch is the actual RISC-V implementation.

This is the first small step in supporting P2P on RISC-V.

Thanks,

Logan
