Merge tag 'for-linus-5.3a-rc1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip

Pull xen updates from Juergen Gross:
 "Fixes and features:

   - A series to introduce a common command line parameter for disabling
     paravirtual extensions when running as a guest in virtualized
     environment

   - A fix for int3 handling in Xen pv guests

   - Removal of the Xen-specific tmem driver as support of tmem in Xen
     has been dropped (and it was experimental only)

   - A security fix for running as Xen dom0 (XSA-300)

   - A fix for IRQ handling when offlining cpus in Xen guests

   - Some small cleanups"
