IB/hfi1: Optimize devdata cachelines
Profiling shows hot path struct members that need
to be in a minimum set of cachelines.
Group these struct member in the same cacheline:
sc2vl_lock
sc2vl
rhf_rcv_function_map
rcv_limit
rhf_offset
Group these struct member in the same cacheline:
process_pio_send
process_dma_send
pport
rcd
int_counter
flags
num_pports
first_user_ctxt
Fill holes in struct hfi1_devdata revealed by pahole.
