[S+Q2 00/19] SLUB with queueing (V2) beats SLAB netperf TCP_RR
The following patchset cleans some pieces up and then equips SLUB with per cpu queues that work similar to SLABs queues. With that approach SLUB wins significantly in hackbench and improves also on tcp_rr.

[S+Q2 04/19] slub: Use a constant for a unspecified node.
kmalloc_node() and friends can be passed a constant -1 to indicate that no choice was made for the node from which the object needs to come. Use NUMA_NO_NODE instead of -1.

[PATCH, RT, RFC] Hacks allowing -rt to run on POWER7 / Powerpc.
[PATCH, RT, RFC] Hacks allowing -rt to run on POWER7 / Powerpc. We've been seeing some issues with userspace randomly SIGSEGV'ing while running the -RT kernels on POWER7 based systems. After lots of debugging, head scratching, and experimental changes to the code, the problem has been narrowed down such that w... 9 Jul 2010 16:05
