Subject: [GIT PULL] xen: branch for v5.19-rc2

Linus,

Please git pull the following tag:

 git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git for-linus-5.19a-rc2-tag

xen: branch for v5.19-rc2

It contains:
- a small cleanup removing "export" of an __init function
- a small series adding a new infrastructure for platform flags
- a series adding generic virtio support for Xen guests (frontend side)

Thanks.

Juergen
