[PATCH 0/2] sriov enablement on s390

[Sebastian Ott <sebott@linux.ibm.com>]

Hello Bjorn,

On s390 we currently handle SRIOV within firmware. Which means
that the PF is under firmware control and not visible to operating
systems. SRIOV enablement happens within firmware and VFs are
passed through to logical partitions.

I'm working on a new mode were the PF is under operating system
control (including SRIOV enablement). However we still need
firmware support to access the VFs. The way this is supposed
to work is that when firmware traps the SRIOV enablement it
will present machine checks to the logical partition that
triggered the SRIOV enablement and provide the VFs via hotplug
events.

The problem I'm faced with is that the VF detection code in
sriov_enable leads to unusable functions in s390.

Would you consider the following patches?
