1. Detect whether KVM can set set guest SError syndrome 2. Support to Set VSESR_EL2 and inject SError by user space. 3. Support live migration to keep SError pending state and VSESR_EL2 value. 4. ACPI 6.1 adds support for NOTIFY_SEI as a GHES notification mechanism, so support this notification in software, KVM or kernel ARCH code call handle_guest_sei() to let ACP driver to handle this notification. Change since V10: Address James's comments, thanks James 1. Merge the helper function with the user. 2. Move the ISS_MASK into pend_guest_serror() to clear top bits 3. Make kvm_vcpu_events struct align to 4 bytes 4. Add something check in the kvm_arm_vcpu_set_events() 5. Check kvm_arm_vcpu_get/set_events()'s return value. 6. Initialise kvm_vcpu_events to 0 so that padding transferred to user-space doesn't contain kernel stack.
