Subject: mm/page_alloc.c: remove unused variable in free_area_init_core()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=7f3eb55bfad8a6dfd880559210f5b21737d69815;p=deliverable%2Flinux.git

mm/page_alloc.c: remove unused variable in free_area_init_core()

Commit febd5949e134 ("mm/memory hotplug: init the zone's size when
calculating node totalpages") refines the function
free_area_init_core().

After doing so, these two parameters are not used anymore.

This patch removes these two parameters.
