2009-04-11ixgbe: add define to support 82599 64 IVAR registersDon Skidmore
82599 supports 64 IVAR registers this patch adds a define to allow us to access them.

2009-04-09RDS/IW+IB: Set recv ring low water mark to 1/2 full.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.

2009-04-07Fix build errors due to CONFIG_BRANCH_TRACER=yLinus Torvalds
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.
