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/2.5.74/patch-2.5.74-mjb1.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 2.5.73-mjb2 (~ = changed, + = added, - = dropped) Notes: Mostly just a merge up Now in Linus' tree: - uninitialised timer Mikael Pettersson Fix bogus cleanup so that gcc 2.95.4 works. - sysrq_t_fix Andrew Morton Fix sysrq+t breakage where it showed the same stack for everyone - pci_hotplug Ivan K. Fix up pci hotplug w/o hotplug enabled. New: + gcov Hubertus / Rajan / Paul Larson Code coverage + stack_fix William Lee Irwin Fix a 4K stack issue Dropped: - upside_down William Lee Irwin Broke things. - schedstat Rick Lindsley Provide stats about the scheduler under /proc/schedstat - schedstat2 Rick Lindsley Provide more stats about the scheduler under /proc/schedstat - schedstat-scripts Rick Lindsley Provide some scripts for schedstat analysis under scripts/ (didn't merge cleanly into 74, awaiting update from Rick). 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 pidmaps_nodepages (Dave Hansen) Present in this patch: early_printk Dave Hansen / Keith Mannthey Allow printk before console_init confighz Andrew Morton / Dave Hansen Make HZ a config option of 100 Hz or 1000 Hz config_page_offset Dave Hansen / Andrea Make PAGE_OFFSET a config option numameminfo Martin Bligh / Keith Mannthey Expose NUMA meminfo information under /proc/meminfo.numa sched_tunables Robert Love Provide tunable parameters for the scheduler (+ NUMA scheduler) 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. kgdb Andrew Morton The older version of kgdb, synched with 2.5.54-mm1 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 4k_stacks_vs_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 spinlock_inlining Andrew Morton & Martin J. Bligh Inline spinlocks for profiling. Made into a ugly config option by me. lockmeter John Hawkes / Hanna Linder Locking stats. 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 local_balance_exec Martin J. Bligh Modify balance_exec to use node-local queues when idle tcp_speedup Martin J. Bligh Speedup TCP (avoid double copy) as suggested by Linus disable preempt Martin J. Bligh I broke preempt somehow, temporarily disable it to stop accidents ppc64 fixes Anton Blanchard Various PPC64 fixes / updates config_debug Dave Hansen Make '-g' for the kernel a config option akpm_bear_pit Andrew Morton Add a printk for some buffer error I was hitting 32bit_dev_t Andries Brouwer Make dev_t 32 bit dynamic_hd_struct Badari Pulavarty Allocate hd_structs dynamically lotsa_sds Badari Pulavarty Create some insane number of sds iosched_hashes Badari Pulavarty Twiddle with the iosched hash tables for fun & profit per_node_idt Zwane Mwaikambo Per node IDT so we can do silly numbers of IO-APICs on NUMA-Q config_numasched Dave Hansen Turn NUMA scheduler into a config option lockmeter_tytso Ted Tso Fix lockmeter aiofix2 Mingming Cao fixed a bug in ioctx_alloc() config_irqbal Keith Mannthey Make irqbalance a config option fs_aio_1_retry Suparna Bhattacharya Filesystem aio.

Bligh Tell me what the real load average is, and tell me per cpu. 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. swsusp_state_check Matt Dobson Fix a check in s/w suspend code pfn_to_nid Martin J.
