From 5639bc4a64786c94eba3d2ba6a4ff4b290da1fb1 Mon Sep 17 00:00:00 2001 From: Hillf Danton Date: Tue, 22 Nov 2011 14:38:02 +0000 Subject: MIPS: Hugetlb: Keep TLB cache hot while flushing If we only flush the TLB of the given huge page, the TLB cache remains hot for the relevant mm as it is, and less will be refilled after flush, huge or not.
