The patchset contains mainly scalability and NUMA stuff, and anything else that stops things from irritating me. It's meant to be pretty stable, not so much a testing ground for new stuff.
I'd be very interested in feedback from anyone willing to test on any platform, however large or small.
ftp://ftp.kernel.org/pub/linux/kernel/people/mbligh/2.5.72/patch-2.5.72-mjb2.bz2
additional patches that can be applied if desired:
(these three form the qlogic feral driver) ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.72/2.5.72-mm1/broken-out/linux-isp.patch ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.72/2.5.72-mm1/broken-out/isp-update-1.patch ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.72/2.5.72-mm1/broken-out/isp-remove-pci_detect.patch
Since 2.5.72-mjb1 (~ = changed, + = added, - = dropped)
Notes: I applied lots of patches which affect similar areas. They all went on without any problems. That's a worse omen than waking up in a pentagram full of black candles ... chances I haven't managed to screw something up are minimal. Go ahead, break it. Make my day.
Now in Linus' tree:
New:
reslabify-pmd-pgd William Lee Irwin Stick things back in the slab. Or something. separate_pmd Dave Hansen Separate kernel pmd per task. banana_split Dave Hansen Make PAGE_OFFSET play twister and limbo. percpu_real_loadavg Dave Hansen / Martin J. Bligh Tell me what the real load average is, and tell me per cpu. numa_large_pages William Lee Irwin Place large pages in sensible places. list-of-lists Martin J. Bligh / Dave McCracken Sort the list of vmas off an address space in a fancy-pants way. nolock Dave McCracken Nah, we don't like locks. proc_pid_readdir Manfred Spraul Make proc_pid_readdir more efficent. Allegedly. mbind_part1 Matt Dobson Bind some memory for NUMA. mbind_part2 Matt Dobson Bind some more memory for NUMA. per_node_rss Matt Dobson Track which nodes tasks mem is on, so sched can be sensible. sysfs_fix Pat Mochel Fix something in sysfs, I forget what. Dave was complaining.

percpu_loadavg Martin J. Bligh In favour of cleaned up version from Dave.
