[GIT PULL] xen: branch for v5.9-rc4

Linus,

Please git pull the following tag:

 git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git for-linus-5.9-rc4-tag

xen: branch for v5.9-rc4

It contains a small series for fixing a problem with Xen PVH guests
when running as backends (e.g. as dom0). Mapping other guests' memory
now is working via ZONE_DEVICE, thus not requiring to abuse the memory
hotplug functionality for that purpose.

Thanks.

Juergen

Tssk. This really isn't a bug-fix, it's clearly new development.

I'm going to let it slide since it seems so contained, but don't do this.

Thanks for taking it.

I agree I should have spelled out the nature of the patch more clearly
and add more reasoning why you might consider taking it.
