delivery_mode of kvm_ioapic_redirect_entry, is 3 bits width value, should be shifted 8bits when check with APIC_DM_FIXED whose value bits are from bit 8 to bit 10. although it works because APIC_DM_FIXED is zero Signed-off-by: Li RongQing <lirongqing@baidu.com> --- arch/x86/kvm/ioapic.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
