From c30f8a6c6d74f67bc2107726cc61a1e7c71e9740 Mon Sep 17 00:00:00 2001 From: Hollis Blanchard Date: Mon, 24 Nov 2008 11:37:38 -0600 Subject: KVM: ppc: stop leaking host memory on VM exit When the VM exits, we must call put_page() for every page referenced in the shadow TLB. Without this patch, we usually leak 30-50 host pages (120 - 200 KiB with 4 KiB pages). The maximum number of pages leaked is the size of our shadow TLB, 64 pages.
