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/2.5.68/patch-2.5.68-mjb1.bz2 additional: (these two form the qlogic feral driver) ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.67/2.5.67-mm1/broken-out/linux-isp.patch ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.67/2.5.67-mm1/broken-out/isp-update-1.patch (shared pagetables - will appear later ;-)) ftp://ftp.kernel.org/pub/linux/kernel/people/mbligh/2.5.68/shpte (some NUMA info, but scuppers some things) http://www.aracnet.com/~fletch/linux/2.5.59/pidmaps_nodepages Since 2.5.67-mjb2 (~ = changed, + = added, - = dropped) Notes: Predominantly just a syncup with 68. Now in Linus' tree: - vmalloc_stats Dave Hansen Expose useful vmalloc statistics - rmap_speedups Andrew Morton Speed up various things in rmap - concurrent_balloc Alex Tomas Concurrent ext2 block allocation - makes SDET & dbench go whizzy fast. - concurrent_inode Alex Tomas Concurrent ext2 inode allocation - makes SDET & dbench go whizzy fast. - meminfo-doc Dave Hansen Document all those mysterious fields in /proc/meminfo New: + node_balance Martin J. Bligh Turn on node balance - it's not overagressive anymore ~ partial_objrmap Dave McCracken Object based rmap for filebacked pages. Pending: Hyperthreaded scheduler (Ingo Molnar) scheduler callers profiling (Anton or Bill Hartner) Child runs first (akpm) Kexec e1000 fixes Update the lost timer ticks code Present in this patch: early_printk Dave Hansen et al.

Bligh Turn on node balance - it's not overagressive anymore irq_affinity Martin J. Bligh Workaround for irq_affinity on clustered apic mode systems (eg x440) partial_objrmap Dave McCracken Object based rmap for filebacked pages. objrmap_fix Dave McCracken Fix detection of anon pages objrmap_fixes Dave McCracken / Hugh Dickins Fix up some mapped sizing bugs in objrmap objrmap_mapcount Dave McCracken Fix up some mapped sizing bugs in objrmap kgdb Andrew Morton The older version of kgdb, synched with 2.5.54-mm1 kprobes Vamsi Krishna S Add kernel probes hooks to the kernel thread_info_cleanup (4K stacks pt 1) Dave Hansen / Ben LaHaise Prep work to reduce kernel stacks to 4K interrupt_stacks (4K stacks pt 2) Dave Hansen / Ben LaHaise Create a per-cpu interrupt stack. stack_usage_check (4K stacks pt 3) Dave Hansen / Ben LaHaise Check for kernel stack overflows. 4k_stack (4K stacks pt 4) Dave Hansen Config option to reduce kernel stacks to 4K fix_kgdb Dave Hansen Fix interaction between kgdb and 4K stacks stacks_from_slab William Lee Irwin Take kernel stacks from the slab cache, not page allocation. thread_under_page William Lee Irwin Fix THREAD_SIZE < PAGE_SIZE case lkcd LKCD team Linux kernel crash dump support percpu_loadavg Martin J. Bligh Provide per-cpu loadaverages, and real load averages spinlock_inlining Andrew Morton Inline spinlocks for profiling. Made into a ugly config option by me. summit_pcimap Matt Dobson Provide pci bus -> node mapping for x440 # shpte Dave McCracken Shared pagetables reiserfs_dio Mingming Cao DIO for Reiserfs sched_interactive Ingo Molnar Bugfix for interactive scheduler kgdb_cleanup Martin J. Bligh Stop kgdb renaming schedule to do_schedule when it's not even enabled acenic_fix Martin J. Bligh Fix warning in acenic driver sisfix Martin J. Bligh Fix warning & bug in sis900 driver local_balance_exec Martin J. Bligh Modify balance_exec to use node-local queues when idle membind Matt Dobson NUMA memory binding API tcp_speedup Martin J. Bligh Speedup TCP (avoid double copy) as suggested by Linus early_printk_fix Keith Mannthey Fix commandline parsing in early printk (yay!) disable preempt Martin J. Bligh I broke preempt somehow, temporarily disable it to stop accidents sched_idle Martin J. Bligh Call load_balance with proper idle flag (pointed out by John Hawkes) diskstats Rick Lindsley Make disk stats available in /proc so they scale to lotsa disks. ppc64 fixes Anton Blanchard Various PPC64 fixes / updates numameminfo fix Martin J. Bligh Correct /proc/meminfo.numa for zholes_size. more_async Andrew Morton Make MS_ASYNC more async separate_pmd Dave Hansen Separate kernel pmd per process config_debug Martin J.

Fix some random thing in devfs iosched_hashes Badari Pulavarty Twiddle with the iosched hash tables for fun & profit lotsa_sds Badari Pulavarty Create some insane number of sds per_node_idt Zwane Mwaikambo Per node IDT so we can do silly numbers of IO-APICs on NUMA-Q banana_split Dave Hansen Provide non PMD aligned splits with PAE mode (eg 3.5:0.5) tulip_warning Dave Hansen Fix silly warning in tulip driver for PAE mode -mjb Martin J. Bligh Add a tag to the makefile
