[PATCH 1/2] mm/mmap.c: Remove redundant variable 'addr' in arch_get_unmapped_area_topdown()

From: Yang Fan
Date: Sun Jan 20 2019 - 03:13:43 EST

The variable 'addr' is redundant in arch_get_unmapped_area_topdown(),
just use parameter 'addr0' directly. Then remove the const qualifier
of the parameter, and change its name to 'addr'.
