x86/platform/uv/BAU: Add status mmr location fields to bau_control
The location of the ERROR and BUSY status bits depends on the descriptor index, i.e. the CPU, of the message. Since this index does not change, there is no need to calculate the mmr and index location during message processing. The less work we do in the hot path the better. Add status_mmr and status_index fields to bau_control and compute their values during initialization. Add kerneldoc descriptions for the new fields. Update uv*_wait_completion to use these fields rather than receiving the information as parameters. Signed-off-by:Andrew Banman <abanman@hpe.com> Acked-by:
