[PATCH V1 1/1] Drivers: hv: Fix a bug in get_vp_index()

From: K. Y. Srinivasan
Date: Fri May 17 2013 - 11:56:49 EST

Linux' notion of cpuid is different from the Host's notion of CPUID. In the
call to bind the channel interrupts, we should use the host's notion of
CPU Ids. Fix this bug.

In this version fixed the Subject line.
