This is a rebase/resend of earlier patches. I skipped the pure cosmetic patches for now. Mostly this is consolidation earlier changes, removing dead code etc. The important part is the change for allowing a vmbus channel to get callback directly in interrupt mode; this is necessary for NAPI support.

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

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.
