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.

Then during the signal\nsetup path we got preempted when we are just before the sanitize_i387_state()\nin arch/x86/kernel/xsave.c:save_i387_xstate(). And when we come back we\nwill have the fpu registers live that can hit the bug_on.\n\nSimilarly during core dump, other threads can context-switch in and out\n(because of spurious wakeups while waiting for the coredump to finish in\n kernel/exit.c:exit_mm()) and the main thread dumping core can run into this\nbug when it finds some other thread with its fpu registers live on some other cpu.\n\nSo remove the paranoid check for now, even though it caught a bug in the\nmulti-threaded core dump case (fixed in the previous patch).\n\nSigned-off-by: Suresh Siddha \u003csuresh.b.siddha@intel.com\u003e\nLink: http://lkml.kernel.org/r/1336692811-30576-3-git-send-email-suresh.b.siddha@intel.com\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nSigned-off-by: H.
