...the vmbus_probe() and vmbus_child_device_register() functions. Fixed a bug in the probe failure path as part of this cleanup. 2) The Windows host cannot handle the vmbus_driver being unloaded and subsequently loaded. Cleanup the driver with this in mind. 3) Get rid of struct hv_bus that embedded struct bus_type to conform with the LDM. 4) Add probe/remove/shutdown functions to struct hv_driver to conform to LDM. 5) On some older Hyper-V hosts, the Linux PCI sub-sytem is not able to allocate irq resources to the vmbus driver.

This patch-set fixes the following issues in the vmbus driver (vmbus_drv.c): Make vmbus driver a platform pci device and cleanup root device management and irq allocation (patches 1/12 through 3/12): 1) Make vmbus driver a platform pci driver. 2) Cleanup root device management. 3) Leverage the pci model for allocating irq. General cleanup of vmbus driver (patches 4/12 though 12/12): 1)

Further cleanup of the vmbus driver: 1) Cleanup the interrupt handler by inlining some code. 2) Ensure message handling is performed on the same CPU that takes the vmbus interrupt. 3) Check for events before messages (from the host). 4) Disable auto eoi for the vmbus interrupt since Linux will eoi the interrupt anyway. 5) Some general cleanup. Regards, K. Y

Further cleanup of the hv drivers. 1) Cleanup reference counting. 2) Handle all block devices using the storvsc driver. I have modified the implementation here based on Christoph's feedback on my earlier implementation. 3) Fix bugs. 4) Accomodate some host side scsi emulation bugs. 5) In case of scsi errors off-line the device.

Further cleanup of the hv drivers: 1) Continue to cleanup our drivers to conform to the Linux Driver Model. 2) Fix some long standing bugs with regards to unloading and reloading the drivers - block, net and stor. 3) VMBUS is an ACPI enumerated device; make VMBUS an ACPI bus driver. 4) Get rid of channel polling code; instead the channel receive paths will be purely interrupt

This patch set removes all un-needed DPRINT and printk calls and replaces the remaining ones with the correct pr_, dev_ and netdev_ calls from hv_vmbus, hv_netvsc, hv_timesource and hv_utils. Several DPRINTS are remaining that will be cleaned up in my next set of patches. They deal with printing out certain debugging that will be implemented slightly differently.
