ARM DMA-mapping updates from Marek Szyprowski:\n \"These patches contain two major updates for DMA mapping subsystem\n (mainly for ARM architecture). First one is Contiguous Memory\n Allocator (CMA) which makes it possible for device drivers to allocate\n big contiguous chunks of memory after the system has booted.\n\n The main difference from the similar frameworks is the fact that CMA\n allows to transparently reuse the memory region reserved for the big\n chunk allocation as a system memory, so no memory is wasted when no\n big chunk is allocated. Once the alloc request is issued, the\n framework migrates system pages to create space for the required big\n chunk of physically contiguous memory.\n\n For more information one can refer to nice LWN articles:\n\n - \u0027A reworked contiguous memory allocator\u0027:\n\t\thttp://lwn.net/Articles/447405/\n\n - \u0027CMA and ARM\u0027:\n\t\thttp://lwn.net/Articles/450286/\n\n - \u0027A deep dive into CMA\u0027:\n\t\thttp://lwn.net/Articles/486301/\n\n - and the following thread with the patches and links to all previous\n versions:\n\t\thttps://lkml.org/lkml/2012/4/3/204\n\n The main client for this new framework is ARM DMA-mapping subsystem.\n\n The second part provides a complete redesign in ARM DMA-mapping\n subsystem. The core implementation has been changed to use common\n struct dma_map_ops based infrastructure with the recent updates for\n new dma attributes merged in v3.4-rc2. This allows to use more than\n one implementation of dma-mapping calls and change/select them on the\n struct device basis. The first client of this new infractructure is\n dmabounce implementation which has been completely cut out of the\n core, common code.\n\n The last patch of this redesign update introduces a new, experimental\n implementation of dma-mapping calls on top of generic IOMMU framework.\n This lets ARM sub-platform to transparently use IOMMU for DMA-mapping\n calls if one provides required IOMMU hardware.\n\n For more information please refer to the following thread:\n\t\thttp://www.spinics.net/lists/arm-kernel/msg175729.html\n\n The last patch merges changes from both updates and provides a\n resolution for the conflicts which cannot be avoided when patches have\n been applied on the same files (mainly arch/arm/mm/dma-mapping.c).\"\n\nAcked by Andrew Morton \u003cakpm@linux-foundation.org\u003e:\n \"Yup, this one please.

Removing the need to add\n an additional check to see if the user namespace of the compared\n uids remains the same.\n\n - With the user namespaces compiled out the performance is as good or\n better than it is today.\n\n - For most operations absolutely nothing changes performance or\n operationally with the user namespace enabled.\n\n - The worst case performance I could come up with was timing 1\n billion cache cold stat operations with the user namespace code\n enabled.

The LFS\n experience suggests not lying and returning an error code might be\n better, but the historical precedent with uids is different and I\n can not think of anything that would break by lying about a uid we\n can\u0027t map.\n\n - Capabilities are localized to the current user namespace making it\n safe to give the initial user in a user namespace all capabilities.\n\n My git tree covers all of the modifications needed to convert the core\n kernel and enough changes to make a system bootable to runlevel 1.\"\n\nFix up trivial conflicts due to nearby independent changes in fs/stat.c\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (46 commits)\n userns: Silence silly gcc warning.\n cred: use correct cred accessor with regards to rcu read lock\n userns: Convert the move_pages, and migrate_pages permission checks to use uid_eq\n userns: Convert cgroup permission checks to use uid_eq\n userns: Convert tmpfs to use kuid and kgid where appropriate\n userns: Convert sysfs to use kgid/kuid where appropriate\n userns: Convert sysctl permission checks to use kuid and kgids.\n userns: Convert proc to use kuid/kgid where appropriate\n userns: Convert ext4 to user kuid/kgid where appropriate\n userns: Convert ext3 to use kuid/kgid where appropriate\n userns: Convert ext2 to use kuid/kgid where appropriate.\n userns: Convert devpts to use kuid/kgid where appropriate\n userns: Convert binary formats to use kuid/kgid where appropriate\n userns: Add negative depends on entries to avoid building code that is userns unsafe\n userns: signal remove unnecessary map_cred_ns\n userns: Teach inode_capable to understand inodes whose uids map to other namespaces.\n userns: Fail exec for suid and sgid binaries with ids outside our user namespace.\n userns: Convert stat to return values mapped from kuids and kgids\n userns: Convert user specfied uids and gids in chown into kuids and kgid\n userns: Use uid_eq gid_eq helpers when comparing kuids and kgids in the vfs\n ...\n" }, { "commit": "2ff2b289a695807e291e1ed9f639d8a3ba5f4254", "tree": "e4b7f44e5cc1582ba2be8aeba221f4841f4c86a6", "parents": [ "88d6ae8dc33af12fe1c7941b1fae2767374046fd", "73787190d04a34e6da745da893b3ae8bedde418f" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue May 22 18:18:55 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue May 22 18:18:55 2012 -0700" }, "message": "Merge branch \u0027perf-core-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip\n\nPull perf changes from Ingo Molnar:\n \"Lots of changes:\n\n - (much) improved assembly annotation support in perf report, with\n jump visualization, searching, navigation, visual output\n improvements and more.\n\n - kernel support for AMD IBS PMU hardware features.

These IPIs are useful and cannot be avoided\naltogether, but in certain cases it is possible to interrupt only specific\nCPUs that have useful work to do and not the entire system.\n\nThis patch set, inspired by discussions with Peter Zijlstra and Frederic\nWeisbecker when testing the nohz task patch set, is a first stab at trying\nto explore doing this by locating the places where such global IPI calls\nare being made and turning the global IPI into an IPI for a specific group\nof CPUs. The purpose of the patch set is to get feedback if this is the\nright way to go for dealing with this issue and indeed, if the issue is\neven worth dealing with at all. Based on the feedback from this patch set\nI plan to offer further patches that address similar issue in other code\npaths.\n\nThis patch creates an on_each_cpu_mask() and on_each_cpu_cond()\ninfrastructure API (the former derived from existing arch specific\nversions in Tile and Arm) and uses them to turn several global IPI\ninvocation to per CPU group invocations.\n\nCore kernel:\n\non_each_cpu_mask() calls a function on processors specified by cpumask,\nwhich may or may not include the local processor.\n\nYou must not call this function with disabled interrupts or from a\nhardware interrupt handler or from a bottom half handler.\n\narch/arm:\n\nNote that the generic version is a little different then the Arm one:\n\n1.

It holds a number of\n low level bits with no/few dependencies that are commonly used (eg.\n memory barriers) and a number of bits with more dependencies that\n aren\u0027t used in many places (eg. switch_to()).\n\n These patches break asm/system.h up into the following core pieces:\n\n (1) asm/barrier.h\n\n Move memory barriers here. This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here. Other process execution related bits\n could perhaps go here from asm/processor.h.\n\n (4) asm/cmpxchg.h\n\n Move xchg() and cmpxchg() here as they\u0027re full word atomic ops and\n frequently used by atomic_xchg() and atomic_cmpxchg().\n\n (5) asm/bug.h\n\n Move die() and related bits.\n\n (6) asm/auxvec.h\n\n Move AT_VECTOR_SIZE_ARCH here.\n\n Other arch headers are created as needed on a per-arch basis.\"\n\nFixed up some conflicts from other header file cleanups and moving code\naround that has happened in the meantime, so David\u0027s testing is somewhat\nweakened by that.
