[PATCH 0/5] Various of SR-IOV fixes and cleanup

From: Alexander Duyck
Date: Tue Oct 27 2015 - 16:52:15 EST

This patch set is meant to address several issues found in recent patches
currently in the pci/virtualization branch.

The first two patches address possible issues in initialization.
Specifically the fact that offset and stride cannot be read while numvfs is
0, and that the BARs need to be reset if totalVFs has increased because the
BIOS likely allocated the given resources under the assumption of a smaller
number of VFs being available.

The last 3 address a number of issues in sriov_enable. They started as
just a patch to address the offset and stride issues, however there were
some other issues found related to pcibios_enable_sriov that I decided to
address as well, and then there was some minor cleanup in addition to all
of that.


Alexander Duyck (5):
iov: Update virtfn_max_buses to validate offset and stride
iov: Reset resources to 0 if totalVFs increases after enabling ARI
iov: Fix sriov_enable exception handling path
iov: Variable and loop cleanup for sriov_disable and sriov_enable
iov: Update sriov_enable to correctly handle offset and stride
