The first patch:
[PATCH v3 1/2] xen/pvhvm: If xen_platform_pci=0 is set don't blow up
I would like to commit to stable as it is fixing an eggregious bug -
where we blow up if the guest config has: "xen_platform_pci=0" setup.
This bug has been in existence for years and it is time to stamp it out.
The second patch is a cleanup - not a stable candidate.
It touches all of the Xen frontend drivers and adds the logic of:
"if user disabled us, don't init" - with variations. As you can
specify exactly which ones you want to init and which ones
not (Linux runtime parameter 'xen_emul_unplug'). But for the majority
of drivers - it is just an on/off switch.
Since it touches a lot of maintainers I figured I would send it
to Linus on Wednesday or Thursday.
Thank you!
