Pull xen fixes from Juergen Gross: "This contains the following fixes/cleanups: - the removal of a BUG_ON() which wasn't necessary and which could trigger now due to a recent change - a correction of a long standing bug happening very rarely in Xen dom0 when a hypercall buffer from user land was not accessible by the hypervisor for very short periods of time due to e.g. page migration or compaction - usage of EXPORT_SYMBOL_GPL() instead of EXPORT_SYMBOL() in a Xen-related driver (no breakage possible as using those symbols without others already exported via EXPORT-SYMBOL_GPL() wouldn't make any sense) - a simplification for Xen PVH or Xen ARM guests - some additional error handling for callers of xenbus_printf()" * tag 'for-linus-4.18-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: xen: Remove unnecessary BUG_ON from __unbind_from_irq() xen: add new hypercall buffer mapping device xen/scsiback: add error handling for xenbus_printf scsi: xen-scsifront: add error handling for xenbus_printf xen/grant-table: Export gnttab_{alloc|free}_pages as GPL xen: add error handling for xenbus_printf xen: share start flags between PV and PVH
