vfio: Split virqfd into a separate module for vfio bus drivers An unintended consequence of commit 42ac9bd18d4f ("vfio: initialize the virqfd workqueue in VFIO generic code") is that the vfio module is renamed to vfio_core so that it can include both vfio and virqfd. That's a user visible change that may break module loading scritps and it imposes eventfd support as a dependency on the core vfio code, which it's really not. virqfd is intended to be provided as a service to vfio bus drivers, so instead of wrapping it into vfio.ko, we can make it a stand-alone module toggled by vfio bus drivers. This has the additional benefit of removing initialization and exit from the core vfio code. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>

vfio: amba: add the VFIO for AMBA devices module to Kconfig Enable building the VFIO AMBA driver. VFIO_AMBA depends on VFIO_PLATFORM, since it is sharing a portion of the code, and it is essentially implemented as a platform device whose resources are discovered via AMBA specific APIs in the kernel.

VFIO: platform: Calxeda xgmac reset module This patch introduces a module that registers and implements a basic reset function for the Calxeda xgmac device. This latter basically disables interrupts and stops DMA transfers. The reset function code is inherited from the native calxeda xgmac driver.
