Subject: [PATCH v4 0/4] Improve dirty ring warning report
It has been known case where no running VCPU context exists when the
vgic/its tables are saved. There are other two unknown cases where we
don't have the running VCPU context: (a) restore VGICv3 LPI pending
status. (b) restoring VGICv3 pending tables.
PATCH[1] includes 'kvm_mmu.h' to 'vgic.h'
PATCH[2] adds unified helper vgic_write_guest_lock()
PATCH[3 - 4] allows no-running-vcpu context for (a) and (b)
