This patch avoids that need by moving all free\nobjects onto a lockless_freelist. The regular freelist continues to exist\nand will be used to free objects. So while we consume the\nlockless_freelist the regular freelist may build up objects.\n\nIf we are out of objects on the lockless_freelist then we may check the\nregular freelist. If it has objects then we move those over to the\nlockless_freelist and do this again. There is a significant savings in\nterms of atomic operations that have to be performed.\n\nWe can even free directly to the lockless_freelist if we know that we are\nrunning on the same processor. So this speeds up short lived objects.\nThey may be allocated and freed without taking the slab_lock. This is\nparticular good for netperf.\n\nIn order to maximize the effect of the new faster hotpath we extract the\nhottest performance pieces into inlined functions. These are then inlined\ninto kmem_cache_alloc and kmem_cache_free. So hotpath allocation and\nfreeing no longer requires a subroutine call within SLUB.\n\n[I am not sure that it is worth doing this because it changes the easy to\nread structure of slub just to reduce atomic ops. However, there is\nsomeone out there with a benchmark on 4 way and 8 way processor systems\nthat seems to show a 5% regression vs. Slab. Seems that the regression is\ndue to increased atomic operations use vs. SLAB in SLUB).

Unfortunately for these\ncommands no GPE events for IBF and OBF are triggered. Since nowadays\nthe EC code uses the ec_intr\u003d1 mode by default, this causes these\noperations to timeout, although they don\u0027t fail. In result, all\noperations that you can do with the msi-laptop.c driver take more or\nless 1s to complete, which is awfully slow.\n\nIn one of the more recent kernels (2.6.20?) the EC subsystem has been\nrevamped. With that change the EC timeout has been increased. before\nthat increase the MSI EC accesses were slow -- but not *that* slow,\nhence I took notice of this limitation of the MSI EC hardware only very\nrecently.\n\nThe standard EC operations on the MSI EC as defined in the ACPI spec\nsupport GPE events properly.\n\nThe following patch adds a new argument \"force_poll\" to the\nec_transaction() function (and friends). If set to 1, the function\nwill poll for IBF/OBF even if ec_intr\u003d1 is enabled. If set to 0 the\ncurrent behaviour is used.

If we have to update per zone or global vm\nstatistics then assume that the pageset will require subsequent draining.\n\nThe expire counter will be decremented on each vm stats update pass until it\nreaches zero.

So we will drain a batch every 3 seconds.\n\nNote that remote node draining is a somewhat esoteric feature that is required\non large NUMA systems because otherwise significant portions of system memory\ncan become trapped in pcp queues. The number of pcp is determined by the\nnumber of processors and nodes in a system. A system with 4 processors and 2\nnodes has 8 pcps which is okay.

The cache reaper does only exists in SLUB as a way to\nprovide compatibility with SLAB. This patch removes the vmstat calls from the\nslab allocators and provides its own handling.\n\nThe advantage is also that we can use a different frequency for the updates.\nRefreshing vm stats is a pretty fast job so we can run this every second and\nstagger this by only one tick. This will lead to some overlap in large\nsystems. F.e a system running at 250 HZ with 1024 processors will have 4 vm\nupdates occurring at once.\n\nHowever, the vm stats update only accesses per node information. It is only\nnecessary to stagger the vm statistics updates per processor in each node. Vm\ncounter updates occurring on distant nodes will not cause cacheline\ncontention.\n\nWe could implement an alternate approach that runs the first processor on each\nnode at the second and then each of the other processor on a node on a\nsubsequent tick. That may be useful to keep a large amount of the second free\nof timer activity.

Enabling oprofile hurts threaded\n programs because of contention on the mmap_sem cache line.\n\n- Using an atomic_inc()/atomic_dec() on inode ref counter or mm ref counter:\n It\u0027s also a cache line ping pong on SMP. It also increases mmap_sem hold time\n because of cache misses.\n\nMost of these scalability problems come from the fact that futexes are in\none global namespace. As we use a central hash table, we must make sure\nthey are all using the same reference (given by the mm subsystem). We\nchose to force all futexes be \u0027shared\u0027. This has a cost.\n\nBut fact is POSIX defined PRIVATE and SHARED, allowing clear separation,\nand optimal performance if carefuly implemented. Time has come for linux\nto have better threading performance.\n\nThe goal is to permit new futex commands to avoid :\n - Taking the mmap_sem semaphore, conflicting with other subsystems.\n - Modifying a ref_count on mm or an inode, still conflicting with mm or fs.\n\nThis is possible because, for one process using PTHREAD_PROCESS_PRIVATE\nfutexes, we only need to distinguish futexes by their virtual address, no\nmatter the underlying mm storage is.\n\nIf glibc wants to exploit this new infrastructure, it should use new\n_PRIVATE futex subcommands for PTHREAD_PROCESS_PRIVATE futexes. And be\nprepared to fallback on old subcommands for old kernels. Using one global\nvariable with the FUTEX_PRIVATE_FLAG or 0 value should be OK.\n\nPTHREAD_PROCESS_SHARED futexes should still use the old subcommands.\n\nCompatibility with old applications is preserved, they still hit the\nscalability problems, but new applications can fly :)\n\nNote : the same SHARED futex (mapped on a file) can be used by old binaries\n*and* new binaries, because both binaries will use the old subcommands.\n\nNote : Vast majority of futexes should be using PROCESS_PRIVATE semantic,\nas this is the default semantic.

If the caller holds some lock, and if one of the queued work happens\nto want that lock as well then accidental deadlocks can occur.\n\nOne example of this is the phy layer: it wants to flush work while holding\nrtnl_lock(). But if a linkwatch event happens to be queued, the phy code will\ndeadlock because the linkwatch callback function takes rtnl_lock.\n\nSo we implement a new function which will flush a *single* work - just the one\nwhich the caller wants to free up. Thus we avoid the accidental deadlocks\nwhich can arise from unrelated subsystems\u0027 callbacks taking shared locks.\n\nflush_work() non-blockingly dequeues the work_struct which we want to kill,\nthen it waits for its handler to complete on all CPUs.\n\nAdd -\u003ecurrent_work to the \"struct cpu_workqueue_struct\", it points to\ncurrently running \"struct work_struct\". When flush_work(work) detects\n-\u003ecurrent_work \u003d\u003d work, it inserts a barrier at the _head_ of -\u003eworklist\n(and thus right _after_ that work) and waits for completition. This means\nthat the next work fired on that CPU will be this barrier, or another\nbarrier queued by concurrent flush_work(), so the caller of flush_work()\nwill be woken before any \"regular\" work has a chance to run.\n\nWhen wait_on_work() unlocks workqueue_mutex (or whatever we choose to protect\nagainst CPU hotplug), CPU may go away. But in that case take_over_work() will\nmove a barrier we queued to another CPU, it will be fired sometime, and\nwait_on_work() will be woken.\n\nActually, we are doing cleanup_workqueue_thread()-\u003ekthread_stop() before\ntake_over_work(), so cwq-\u003ethread should complete its -\u003eworklist (and thus\nthe barrier), because currently we don\u0027t check kthread_should_stop() in\nrun_workqueue().

devices (PNPBIOS or PNPACPI)\n\nThis series converts i386 and x86_64 legacy serial ports to be platform\ndevices and prevents probing for them if we have PNP.\n\nThis prevents double discovery, where a device was found both by the legacy\nprobe and by 8250_pnp.\n\nThis also prevents the serial driver from claiming IRDA devices (unless they\nhave a UART PNP ID). The serial legacy probe sometimes assumed the wrong IRQ,\nso the user had to use \"setserial\" to fix it.\n\nRemoving the need for setserial to make IRDA devices work seems good, but it\ndoes break some things. In particular, you may need to keep setserial from\npoking legacy UART stuff back in by doing something like \"dpkg-reconfigure\nsetserial\" with the \"kernel\" option. Otherwise, the setserial-discovered\n\"UART\" will claim resources and prevent the IRDA driver from loading.\n\nThis patch:\n\nIf we can discover devices using PNP, we can skip some legacy probes.
