[Qemu-devel] [PATCH V11 03/10] scripts/update-linux-headers: import pvrdma headers

[Marcel Apfelbaum <marcel@redhat.com>]

Modify the script to import the headers used by the pvrdma device.
Part of them are interfaces between the guest driver and the device,
import them under include/standart-headers/drivers/infiniband/... .

Remove the unused functions from pvrdma_verbs.h avoiding the
unnecessary import of several infiniband/networking/other headers.
