The patchset contains mainly performance, 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/2.6.0-test10/patch-2.6.0-test10-mjb1.bz2
Since 2.6.0-test9-mjb3 (~ = changed, + = added, - = dropped)
Notes: Mostly a merge forwards.
Now in Linus' tree:
Dropped:
- imcplicit_large_page Adam Litke Breaks PPC64 build. New patch soon.
New:
+ scsi_fix Mike Anderson Fix kobject oops.
+ pci_topology Matt Dobson Expose PCI NUMA topology to userspace
Pending: lotsa_sds config_numasched 4/4 split list_of_lists Hyperthreaded scheduler (Ingo Molnar) scheduler callers profiling (Anton or Bill Hartner) Child runs first (akpm) Kexec e1000 fixes pidmaps_nodepages (Dave Hansen)
Present in this patch:
kgdb Various Stolen from akpm's 2.6.0-test9-mm2

sched_tunables Robert Love Provide tunable parameters for the scheduler (+ NUMA scheduler)
partial_objrmap Dave McCracken Object based rmap for filebacked pages.

disable preempt Martin J. Bligh I broke preempt somehow, temporarily disable it to stop accidents
ppc64 pci fix Anton Blanchard Fix some ppc64 pci thing or other.
per_node_idt Zwane Mwaikambo Per node IDT so we can do silly numbers of IO-APICs on NUMA-Q

percpu_real_loadavg Dave Hansen / Martin J. Bligh Tell me what the real load average is, and tell me per cpu.
nolock Dave McCracken Nah, we don't like locks.
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.
pfn_to_nid Martin J. Bligh Dance around the twisted rats nest of crap in i386 include.
gfp_node_strict Dave Hansen Add a node strict binding as a gfp mask option
page_lock William Lee Irwin Conditionally convert mapping->page_lock back to an rwlock
irqbal_fast Adam Litke Balance IRQs more readily
kcg Adam Litke Acylic call graphs from the kernel. Wheeeeeeeeeeeee!
numa_mem_equals Dave Hansen mem= command line parameter NUMA awareness.
schedstat Rick Lindsley Provide lotsa scheduler statistics
autoswap Con Kolivas Auto-tune swapiness
ext2_fix Andrew Morton Fix a race in ext2
emulex driver Emulex Driver for emulex fiberchannel cards
