Subject: i386: don't check_pgt_cache in flush_tlb_mm
From: Hugh Dickins <hugh@xxxxxxxxxxx>
No other architecture calls check_pgt_cache() from within flush_tlb_mm(),
and i386 is already calling check_pgt_cache() from the usual places,
tlb_finish_mmu() and cpu_idle() (the latter being odd, but not unusual).
flush_tlb_mm() has no business to be freeing pages: remove that line, which
sneaked in with slub's i386 support.
