Putting the constant first is a supposed "best practice" that actually makes

The RDS_LL_SEND_FULL bit should be set when we stop transmitted due to
flow control. Otherwise the send worker will keep trying as opposed to
sleeping until we unthrottle. Saves CPU.Signed-off-by: Steve Wise

Currently the recv ring low water mark is 1/4 the depth. Performance
measurements show that this limits iWARP throughput by flow controlling
the rds-stress senders. Setting it to 1/2 seems to max the T3
performance. I tried even higher levels but that didn't help and it
started to increase the rds thread cpu utilization.Signed-off-by: Steve Wise

The code that enables branch tracing for all (non-constant) branches
plays games with the preprocessor and #define's the C 'if ()' construct
to do tracing.That's all fine, but it fails for some unusual but valid C code that is
sometimes used in macros, notably by the intel-iommu code:if (i=drhd->iommu, drhd->ignored) ..
because now the preprocessor complains about multiple arguments to the
'if' macro.So make the macro expansion of this particularly horrid trick use
varargs, and handle the case of comma-expressions in if-statements. Use
another macro to do it cleanly in just one place.This replaces a patch by David (and acked by Steven) that did this all
inside that one already-too-horrid macro.Tested-by: Ingo Molnar
