Subject[GIT PULL] xen: fixes and features for 5.3-rc1
Date
Linus,

Please git pull the following tag:

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

xen: fixes and features for 5.3-rc1

It contains:

- 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


Thanks.

Juergen
