[GIT PULL] xen: branch for v5.9-rc1b

Linus,

Please git pull the following tag:

 git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git for-linus-5.9-rc1b-tag

xen: branch for v5.9-rc1, 2nd batch

It contains 2 series:

- Removal of 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.


Thanks.

Juergen
