mm/page_alloc: remove track of active PCP lists range in bulk free
Patch series "Two minor cleanups for pcp list in page_alloc".
There are two minor cleanups for pcp list in page_alloc. More details
can be found in respective patches.
This patch (of 2):
After commit fd56eef258a17 ("mm/page_alloc: simplify how many pages are
selected per pcp list during bulk free"), we will drain all pages in
selected pcp list. And we ensured passed count is < pcp->count. Then,
the search will finish before wrap-around and track of active PCP lists
range intended for wrap-around case is no longer needed.
