[OpenRISC] [PATCH 21/31] mm: rename flush_icache_user_range to flush_icache_user_page

Christoph Hellwig
2020-05-10T07:55:00Z

The function currently known as flush_icache_user_range only operates
on a single page. Rename it to flush_icache_user_page as we'll need
the name flush_icache_user_range for something else soon.
