mm/page_table_check: remove unused parameters in page_table_check_clear()
Patch series "Remove unused parameters in page_table_check".
This series remove unused parameters in functions from page_table_check.
The first 2 patches remove unused mm and addr parameters in static common
functions page_table_check_clear and page_table_check_set. The last 6
patches remove unused addr parameter in some externed functions which only
need addr for cleaned page_table_check_clear or page_table_check_set.
There is no intended functional change.
This patch (of 8):
Remove unused mm and addr in function page_table_check_clear().
