From 577ed7f71e9c37a46c45a7bd9a392dd0372a409c Mon Sep 17 00:00:00 2001 From: James Hogan Date: Fri, 1 May 2015 14:56:31 +0100 Subject: KVM: MIPS: Pass type of fault down to kvm_mips_map_page() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit kvm_mips_map_page() will need to know whether the fault was due to a read or a write in order to support dirty page tracking, KVM_CAP_SYNC_MMU, and read only memory regions, so get that information passed down to it via new bool write_fault arguments to various functions.
