Linus,

Please git pull the following tag:

xen: branch for v6.1-rc1

It contains:

- Some minor typo fixes

- A fix of the Xen pcifront driver for supporting the device model to
  run in a Linux stub domain

- A cleanup of the pcifront driver

- A series to enable grant-based virtio with Xen on x86

- A cleanup of Xen PV guests to distinguish between safe and faulting
  MSR accesses

- Two fixes of the Xen gntdev driver

- Two fixes of the new xen grant DMA driver


Thanks.

Juergen
