Hi, Avi
Could you revert the commit d6f9e28239fd6ac6ace6e72b44c257ed3936fdd5 ?
It should be an incorrect fix, and leads to fail to generate asm-offsets.h
under some special configrations. It should be my fault, sorry! Please apply
this one. Thanks!

Greetings,
Following patches are intended to support SR-IOV capability in the
Linux kernel. With these patches, people can turn a PCI device with
the capability into multiple ones from software perspective, which
will benefit KVM and achieve other purposes such as QoS, security,
and etc.
