ARC: mm: switch pgtable_to to pte_t *2015-10-09T11:34:22ZVineet Guptavgupta@synopsys.com2015-08-28T03:09:57Zurn:sha1:e8a75963a4b9433dca55286e222f4dd1cc1ca76c
ARC is the only arch with unsigned long type (vs. struct page *).
Historically this was done to avoid the page_address() calls in various
arch hooks which need to get the virtual/logical address of the table.
Some arches alternately define it as pte_t *, and is as efficient as
unsigned long (generated code doesn't change)
