Merge tag 'for-linus-6.5a-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull xen fixes from Juergen Gross:
- A fix for a performance problem in QubesOS, adding a way to drain the
queue of grants experiencing delayed unmaps faster
- A patch enabling the use of static event channels from user mode,
which was omitted when introducing supporting static event channels
- A fix for a problem where Xen related code didn't check properly for
running in a Xen environment, resulting in a WARN splat

xen: speed up grant-table reclaim
xen/evtchn: Introduce new IOCTL to bind static evtchn
xenbus: check xen_domain in xenbus_probe_initcall
