[PATCH v1 10/15] powerpc/mm: refactor pte_alloc_one() and pte_free() families definition.

Christophe Leroy
2019-04-03T20:06:52Z

Functions pte_alloc_one(), pte_alloc_one_kernel(), pte_free(),
pte_free_kernel() are identical for the four subarches.

This patch moves their definition in a common place.
