  RISC-V: Avoid coupling the T-Head CMOs and Zicbom (2022-09-16 02:59:06 -0700)

----------------------------------------------------------------
RISC-V Fixes for 6.0-rc6

* A handful of build fixes for the T-Head errata, including some
  functional issues the compilers found.
* A fix to avoid bad page permission initialization, which manifests on
  systems that may load modules early.
* A fix for a nasty sigreturn bug.

----------------------------------------------------------------
I have one merge conflict as a result of a treewide fix, I'm getting some odd
output from just showing the merge (it's showing some of the fix too), but I
think the merge itself is OK.  My fix is to keep the write lock

-       mmap_read_lock(mm);
++      mmap_write_lock(mm);
 +      ret = walk_page_range_novma(mm, start, end, &pageattr_ops, NULL,
 +                                  &masks);
-       mmap_read_unlock(mm);
++      mmap_write_unlock(mm);
