This is a misprint in the page table traversal in
srmmu_inherit_prom_mappings`() function which accessed a PMD entry using
PGD rather than PUD.
Since sparc32 has only 3 page table levels, the PGD and PUD are
essentially the same and usage of __nocache_fix() removed the type
checking.
Use PUD for the consistency and to avoid breakage because of upcoming
addition of type checking into __nocache_fix().
Fixes: 7235db268a ("sparc32: use pgtable-nopud instead of 4level-fixup")
