The noinline_for_stack is introduced by commit 666356297ec4 ("vmscan:
set up pagevec as late as possible in shrink_inactive_list()"), its
purpose is to delay the allocation of pagevec as late as possible to
save stack memory. But the commit 2bcf88796381 ("mm: take pagevecs off
reclaim stack") replace pagevecs by lists of pages_to_free. So we do
not need noinline_for_stack, just remove it (let the compiler decide
whether to inline).
