  hw/xen: use correct default protocol for xen-block on x86 (2023-11-06 
10:03:45 +0000)

----------------------------------------------------------------
Bugfixes for emulated Xen support

Selected bugfixes for mainline and stable, especially to the per-vCPU
local APIC vector delivery mode for event channel notifications, which
was broken in a number of ways.

The xen-block driver has been defaulting to the wrong protocol for x86
guest, and this fixes that — which is technically an incompatible change
but I'm fairly sure nobody relies on the broken behaviour (and in
production I *have* seen guests which rely on the correct behaviour,
which now matches the blkback driver in the Linux kernel).

A handful of other simple fixes for issues which came to light as new
features (qv) were being developed.

----------------------------------------------------------------
David Woodhouse (7):
      i386/xen: Don't advertise XENFEAT_supervisor_mode_kernel
      i386/xen: fix per-vCPU upcall vector for Xen emulation
      hw/xen: select kernel mode for per-vCPU event channel upcall vector
      hw/xen: don't clear map_track[] in xen_gnttab_reset()
      hw/xen: fix XenStore watch delivery to guest
      hw/xen: take iothread mutex in xen_evtchn_reset_op()
      hw/xen: use correct default protocol for xen-block on x86
