xen: branch for v5.12-rc3

It contains two patch series and a single patch:

- a small cleanup patch to remove unneeded symbol exports
- a series to cleanup Xen grant handling (avoiding allocations in some
  cases, and using common defines for "invalid" values)
- a series to address a race issue in Xen event channel handling


Thanks.

Juergen
