[PATCH V2 1/3] Drivers: hv: vmbus: Use the vp_index map even for channels bound to CPU 0

From: K. Y. Srinivasan
Date: Sun May 31 2015 - 01:17:01 EST


Map target_cpu to target_vcpu using the mapping table.
We should use the mapping table to transform guest CPU ID to VP Index
as is done for the non-performance critical channels.
While the value CPU 0 is special and will
map to VP index 0, it is good to be consistent.
