Series mm/highmem: Fix fallout from generic kmap_local conversions | expand

Commit Message

Thomas Gleixner Jan. 12, 2021, 5:01 p.m. UTC 
The original PowerPC highmem mapping function used __set_pte_at() to denote
that the mapping is per CPU. This got lost with the conversion to the
generic implementation.

Override the default map function.
