Merge tag 'for-linus-5.9-rc1b-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull more xen updates from Juergen Gross:
- Remove support for running as 32-bit Xen PV-guest.
32-bit PV guests are rarely used, are lacking security fixes for
Meltdown, and can be easily replaced by PVH mode. Another series for
doing more cleanup will follow soon (removal of 32-bit-only pvops
functionality).
- Fixes and additional features for the Xen display frontend driver.
