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"
