Merge tag 'for-linus-5.12b-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull xen fixes from Juergen Gross: "Two fix series and a single cleanup: - a small cleanup patch to remove unneeded symbol exports - a series to cleanup Xen grant handling (avoiding allocations in some cases, and using common defines for "invalid" values) - a series to address a race issue in Xen event channel handling" * tag 'for-linus-5.12b-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: Xen/gntdev: don't needlessly use kvcalloc() Xen/gnttab: introduce common INVALID_GRANT_{HANDLE,REF} Xen/gntdev: don't needlessly allocate k{,un}map_ops[] Xen: drop exports of {set,clear}_foreign_p2m_mapping() xen/events: avoid handling the same event on two cpus at the same time xen/events: don't unmask an event channel when an eoi is pending xen/events: reset affinity of 2-level event when tearing it down
