Subject: parisc: unmap_uncached_pte() use pte_offset_kernel()
Date: Thu, 8 Jun 2023 12:20:00 -0700 (PDT)
unmap_uncached_pte() is working from pgd_offset_k(vaddr), so it should
use pte_offset_kernel() instead of pte_offset_map(), to avoid the
question of whether a pte_unmap() will be needed to balance.
