[Xen-devel] [PATCH 0/4] x86: EOI timer corrections / improvements

["Jan Beulich" <JBeulich@xxxxxxxx>]

The first patch was sent on its own before; this is a plain resend. The
others have been added to address at least the majority of the
questions raised in
https://lists.xenproject.org/archives/html/xen-devel/2019-04/msg00883.html

1: don't keep EOI timer running without need
2: bail early from irq_guest_eoi_timer_fn() when nothing is in flight
3: relax locking in irq_guest_eoi_timer_fn()
4: ACKTYPE_NONE cannot make it into irq_guest_eoi_timer_fn()

Jan
