Subject: [PATCH 0/3] riscv: mm: Do not restrict mmap address based on hint

There have been a couple of reports that using the hint address to
restrict the address returned by mmap hint address has caused issues in
applications. A different solution for restricting addresses returned by
mmap is necessary to avoid breakages.
