KVM: MMU: fix permission_fault() kvm-unit-tests complained about the PFEC is not set properly, e.g,: test pte.rw pte.d pte.nx pde.p pde.rw pde.pse user fetch: FAIL: error code 15 expected 5 Dump mapping: address: 0x123400000000 ------L4: 3e95007 ------L3: 3e96007 ------L2: 2000083 It's caused by the reason that PFEC returned to guest is copied from the PFEC triggered by shadow page table This patch fixes it and makes the logic of updating errcode more clean Signed-off-by: Xiao Guangrong <guangrong.xiao@linux.intel.com> [Do not assume pfec.p=1. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
