  RISC-V: Acquire mmap lock before invoking walk_page_range (2020-06-18 18:46:09 -0700)

RISC-V Fixes for 5.8-rc2

This contains three fixes that I'd like to target for rc2:

* 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.
