      "message": "avoid overflows in kernel/time.c\n\nWhen the conversion factor between jiffies and milli- or microseconds is\nnot a single multiply or divide, as for the case of HZ \u003d\u003d 300, we currently\ndo a multiply followed by a divide.  The intervening result, however, is\nsubject to overflows, especially since the fraction is not simplified (for\nHZ \u003d\u003d 300, we multiply by 300 and divide by 1000).\n\nThis is exposed to the user when passing a large timeout to poll(), for\nexample.\n\nThis patch replaces the multiply-divide with a reciprocal multiplication on\n32-bit platforms.  When the input is an unsigned long, there is no portable\nway to do this on 64-bit platforms there is no portable way to do this\nsince it requires a 128-bit intermediate result (which gcc does support on\n64-bit platforms but may generate libgcc calls, e.g.  on 64-bit s390), but\nsince the output is a 32-bit integer in the cases affected, just simplify\nthe multiply-divide (*3/10 instead of *300/1000).\n\nThe reciprocal multiply used can have off-by-one errors in the upper half\nof the valid output range.  This could be avoided at the expense of having\nto deal with a potential 65-bit intermediate result.  Since the intent is\nto avoid overflow problems and most of the other time conversions are only\nsemiexact, the off-by-one errors were considered an acceptable tradeoff.\n\nAt Ralf Baechle\u0027s suggestion, this version uses a Perl script to compute\nthe necessary constants.  We already have dependencies on Perl for kernel\ncompiles.  This does, however, require the Perl module Math::BigInt, which\nis included in the standard Perl distribution starting with version 5.8.0.\nIn order to support older versions of Perl, include a table of canned\nconstants in the script itself, and structure the script so that\nMath::BigInt isn\u0027t required if pulling values from said table.\n\nRunning the script requires that the HZ value is available from the\nMakefile.  Thus, this patch also adds the Kconfig variable CONFIG_HZ to the\narchitectures which didn\u0027t already have it (alpha, cris, frv, h8300, m32r,\nm68k, m68knommu, sparc, v850, and xtensa.) It does *not* touch the sh or\nsh64 architectures, since Paul Mundt has dealt with those separately in the\nsh tree.\n\nSigned-off-by: H.

We limit the maximum size\nto a lower limit if MAX_ORDER does not allow such large allocations.\n\nFor many architectures this patch will have the effect of adding large\nkmalloc sizes.  x86_64 adds 5 new kmalloc sizes.  So a small amount of\nmemory will be needed for these caches (contemporary SLAB has dynamically\nsizeable node and cpu structure so the waste is less than in the past)\n\nMost architectures will then be able to allocate object with sizes up to\nMAX_ORDER.  We have had repeated breakage (in fact whenever we doubled the\nnumber of supported processors) on IA64 because one or the other struct\ngrew beyond what the slab allocators supported.

      "message": "SLUB core\n\nThis is a new slab allocator which was motivated by the complexity of the\nexisting code in mm/slab.c. It attempts to address a variety of concerns\nwith the existing implementation.\n\nA. Management of object queues\n\n   A particular concern was the complex management of the numerous object\n   queues in SLAB. SLUB has no such queues. Instead we dedicate a slab for\n   each allocating CPU and use objects from a slab directly instead of\n   queueing them up.\n\nB. Storage overhead of object queues\n\n   SLAB Object queues exist per node, per CPU. The alien cache queue even\n   has a queue array that contain a queue for each processor on each\n   node. For very large systems the number of queues and the number of\n   objects that may be caught in those queues grows exponentially. On our\n   systems with 1k nodes / processors we have several gigabytes just tied up\n   for storing references to objects for those queues  This does not include\n   the objects that could be on those queues. One fears that the whole\n   memory of the machine could one day be consumed by those queues.\n\nC. SLAB meta data overhead\n\n   SLAB has overhead at the beginning of each slab. This means that data\n   cannot be naturally aligned at the beginning of a slab block. SLUB keeps\n   all meta data in the corresponding page_struct. Objects can be naturally\n   aligned in the slab. F.e. a 128 byte object will be aligned at 128 byte\n   boundaries and can fit tightly into a 4k page with no bytes left over.\n   SLAB cannot do this.\n\nD. SLAB has a complex cache reaper\n\n   SLUB does not need a cache reaper for UP systems. On SMP systems\n   the per CPU slab may be pushed back into partial list but that\n   operation is simple and does not require an iteration over a list\n   of objects. SLAB expires per CPU, shared and alien object queues\n   during cache reaping which may cause strange hold offs.\n\nE. SLAB has complex NUMA policy layer support\n\n   SLUB pushes NUMA policy handling into the page allocator. This means that\n   allocation is coarser (SLUB does interleave on a page level) but that\n   situation was also present before 2.6.13. SLABs application of\n   policies to individual slab objects allocated in SLAB is\n   certainly a performance concern due to the frequent references to\n   memory policies which may lead a sequence of objects to come from\n   one node after another. SLUB will get a slab full of objects\n   from one node and then will switch to the next.\n\nF. Reduction of the size of partial slab lists\n\n   SLAB has per node partial lists. This means that over time a large\n   number of partial slabs may accumulate on those lists. These can\n   only be reused if allocator occur on specific nodes. SLUB has a global\n   pool of partial slabs and will consume slabs from that pool to\n   decrease fragmentation.\n\nG. Tunables\n\n   SLAB has sophisticated tuning abilities for each slab cache. One can\n   manipulate the queue sizes in detail. However, filling the queues still\n   requires the uses of the spin lock to check out slabs. SLUB has a global\n   parameter (min_slab_order) for tuning. Increasing the minimum slab\n   order can decrease the locking overhead. The bigger the slab order the\n   less motions of pages between per CPU and partial lists occur and the\n   better SLUB will be scaling.\n\nG. Slab merging\n\n   We often have slab caches with similar parameters. SLUB detects those\n   on boot up and merges them into the corresponding general caches. This\n   leads to more effective memory use. About 50% of all caches can\n   be eliminated through slab merging. This will also decrease\n   slab fragmentation because partial allocated slabs can be filled\n   up again. Slab merging can be switched off by specifying\n   slub_nomerge on boot up.\n\n   Note that merging can expose heretofore unknown bugs in the kernel\n   because corrupted objects may now be placed differently and corrupt\n   differing neighboring objects. Enable sanity checks to find those.\n\nH. Diagnostics\n\n   The current slab diagnostics are difficult to use and require a\n   recompilation of the kernel. SLUB contains debugging code that\n   is always available (but is kept out of the hot code paths).\n   SLUB diagnostics can be enabled via the \"slab_debug\" option.\n   Parameters can be specified to select a single or a group of\n   slab caches for diagnostics. This means that the system is running\n   with the usual performance and it is much more likely that\n   race conditions can be reproduced.\n\nI. Resiliency\n\n   If basic sanity checks are on then SLUB is capable of detecting\n   common error conditions and recover as best as possible to allow the\n   system to continue.\n\nJ. Tracing\n\n   Tracing can be enabled via the slab_debug\u003dT,\u003cslabcache\u003e option\n   during boot. SLUB will then protocol all actions on that slabcache\n   and dump the object contents on free.\n\nK. On demand DMA cache creation.\n\n   Generally DMA caches are not needed. If a kmalloc is used with\n   __GFP_DMA then just create this single slabcache that is needed.\n   For systems that have no ZONE_DMA requirement the support is\n   completely eliminated.\n\nL. Performance increase\n\n   Some benchmarks have shown speed improvements on kernbench in the\n   range of 5-10%. The locking overhead of slub is based on the\n   underlying base allocation size. If we can reliably allocate\n   larger order pages then it is possible to increase slub\n   performance much further. The anti-fragmentation patches may\n   enable further performance increases.\n\nTested on:\ni386 UP + SMP, x86_64 UP + SMP + NUMA emulation, IA64 NUMA + Simulator\n\nSLUB Boot options\n\nslub_nomerge\t\tDisable merging of slabs\nslub_min_order\u003dx\tRequire a minimum order for slab caches.

This patch fixes the following bugs:\n- ARCH_S390X does no longer exist, nowadays this has to be expressed\n  through (S390 \u0026\u0026 64BIT)\n- in five architecture specific Kconfig files the UID16 options\n  weren\u0027t removed\n\nAdditionally, it changes the fragile negative dependencies of UID16 to\npositive dependencies (new architectures are more likely to not require\nUID16 support).\n\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nAcked-by: Matt Mackall \u003cmpm@selenic.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
