Merge tag 'for-linus-6.0-rc1b-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull more xen updates from Juergen Gross: - fix the handling of the "persistent grants" feature negotiation between Xen blkfront and Xen blkback drivers - a cleanup of xen.config and adding xen.config to Xen section in MAINTAINERS - support HVMOP_set_evtchn_upcall_vector, which is more compliant to "normal" interrupt handling than the global callback used up to now - further small cleanups * tag 'for-linus-6.0-rc1b-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: MAINTAINERS: add xen config fragments to XEN HYPERVISOR sections xen: remove XEN_SCRUB_PAGES in xen.config xen/pciback: Fix comment typo xen/xenbus: fix return type in xenbus_file_read() xen-blkfront: Apply 'feature_persistent' parameter when connect xen-blkback: Apply 'feature_persistent' parameter when connect xen-blkback: fix persistent grants negotiation x86/xen: Add support for HVMOP_set_evtchn_upcall_vector
