[v3,0/2] ppc: Drop support for QEMU pseries

Message

Hello all,

This small series drops support for the QEMU paravirtualized pseries
machine type in favor of the bare metal PowerNV platform. pseries
support was broken by 74b725a64d80 ('xen/ppc: Implement initial Radix
MMU support'), and instead of maintaining separate code paths to retain
support for the platform, I think it makes the most sense to drop it
entirely.

pseries was originally targeted for initial bringup since it has
historically been much better supported by QEMU, but PowerNV support in
QEMU has recently developed to the point where this is no longer a
concern.  Since I can think of very little practical use for running Xen
under pseries, and supporting it requires non-trivial duplication of
effort, drop support for it entirely.

This also requires a change to the ppc64le CI dockerfile to build a
newer version of QEMU than is available in the bullseye repository.

Thanks,
Shawn
