Subject: [PATCH v2 0/3] 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 vgic3 LPI pending
status. (b) restoring vgic3 pending tables.

PATCH[1]     adds unified helper vgic_write_guest_lock()
PATCH[2 - 3] allows no-running-vcpu context for (a) and (b)

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

Changelog
=========
v2:
  * Add unified helper vgic_write_guest_lock()                 (Oliver)
  * Dropped two patches to refactor mark_page_dirty_in_slot()  (Sean)

Gavin Shan (3):
  KVM: arm64: Add helper vgic_write_guest_lock()
  KVM: arm64: Allow no running vcpu on restoring vgic3 LPI pending
    status
  KVM: arm64: Allow no running vcpu on saving vgic3 pending table
