2015-02-18RDMA/ocrdma: Use unsigned for bit indexRasmus Villemoes
In the expressions idx/32 and idx%32, both idx and 32 have signed type, and unfortunately the C standard prescribes rounding to 0, so unless gcc can prove that idx is non-negative, these cannot be implemented as simple shift respectively mask operations. Help gcc by changing the type of idx to unsigned - this cuts another few instructions from the generated code.

2015-02-18RDMA/ocrdma: Help gcc generate better code for ocrdma_srq_toggle_bitRasmus Villemoes
gcc emits a surprising amount of code in order to flip a bit. One would think that a single instruction is enough. $ scripts/bloat-o-meter /tmp/ocrdma_verbs.o drivers/infiniband/hw/ocrdma/ocrdma_verbs.o add/remove: 0/0 grow/shrink: 0/3 up/down: 0/-142 (-142) function old new delta ocrdma_post_srq_recv 498 460 -38 ocrdma_poll_cq 2010 1962 -48 ocrdma_discard_cqes 495 439 -56 All three calls of ocrdma_srq_toggle_bit happen within spinlocks, so saving a few useless instructions might be worthwhile.
