Subject: [PATCH v3 0/4] Improve dirty ring warning report
Date:   Fri, 27 Jan 2023 07:54:47 +0800

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 vgic3 LPI pending
status. (b) restoring vgic3 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)

v1: https://lore.kernel.org/kvmarm/20230116040405.260935-1-gshan@redhat.com/T/#t
