Thanks for looking at this patch.

The patch to remove arch_unmap() cannot be used as powerpc needs a
replacement.  I will be moving the arch_unmap() call later in the unmap
process like it was before mpx moved it (mpx has been dropped from the
kernel).  I will add you to the Cc for the whole series next time.

Thanks,
Liam
