  riscv: __asm_copy_to-from_user: Fix: Typos in comments (2021-07-23 17:49:12 -0700)

----------------------------------------------------------------
RISC-V Fixes for 5.13-rc3

* A fix to properly set the memory size, which fixes 32-bit systems.
* A fix to allow the initrd to load anywhere in memory, rather that
  restricting it to the first 256MiB.
* A fix for the mem= parameter on 64-bit systems, to properly account
  for the maximum supported memory now that the kernel is outside the
  linear map.
* A fix to avoid installing mappings into the last 4KiB of memory, which
  conflicts with error values.
* A fix to avoid the stack from being freed while it is being walked.
* A handful of fixes to the new copy to/from user routines.
---
There is one particularly odd bit in the history here: the fix for the 32-bit
boot failure is based on an older release, because a recent feature addition
also fixed the bug.  I wanted to take that patch so it could be backported to
stable, but it's erased by its own merge.  Not sure if there's a better way to
do this, but I figured this was saner than reverting the feature and then
bringing it back.
