Merge tag 'riscv-for-linus-5.8-rc2' of git://git.kernel.org/pub/scm/linux/kernel...

Pull RISC-V fixes from Palmer Dabbelt:

 - a workaround for a compiler surprise related to the "r" inline
   assembly that allows LLVM to boot.

 - a fix to avoid WX-only mappings, which the ISA does not allow. While
   this probably manifests in many ways, the bug was found in stress-ng.

 - a missing lock in set_direct_map_*(), which due to a recent lockdep
   change started asserting.
