Linus,

Please git pull the following tag:

git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git for-linus-5.11-rc4-tag

xen: branch for v5.11-rc4

It contains:

- A series for fixing a regression when running as a fully virtualized
guest on an old Xen hypervisor not supporting PV interrupt callbacks
for HVM guests.

- A patch for adding support to query Xen resource sizes (setting was
possible already) from user mode.


Thanks.

Juergen
