This group of patches removes all DPRINT from hv_vmbus.ko. It is divided in several patches due to size. All DPRINT calls have been removed, and where needed have been replaced with pr_XX native calls. Many debug DPRINT calls have been removed outright. The amount of clutter this driver prints has been significantly reduced. Signed-off-by: Hank Janssen <hjanssen at microsoft.com>

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. The remaining hv_storvsc and

Booting a Xen PVH guest requires a special boot entry as it is mandatory to setup some Xen-specific interfaces rather early. When grub or OVMF are used as boot loaders, however, those will fill the boot parameters in zeropage and there is no longer a need to do something PVH specific in the early boot path. This patch series adds support for that scenario by identifying PVH environment and doing

Further cleanup of the hv drivers. 1) Implement code for autoloading the vmbus drivers without using PCI or DMI signatures. I have implemented this based on Greg's feedback on my earlier implementation. 2) Cleanup error handling across the board and use standard Linux error codes. 3) General cleanup Regards, K. Y

Further cleanup of the hv drivers. Back in June I had sent two patch sets to address these issues. I have addressed the comments I got from the community on my earlier patches here: 1) Implement code for autoloading the vmbus drivers without using PCI or DMI signatures. I have implemented this based on Greg's feedback on my earlier implementation. 2) Cleanup error handling across
