The exception\nto this are kernel threads, which don\u0027t have an mm, and so borrow\nthe mm from the last thread which ran. The system is bootstrapped\nby the initial kernel thread using init\u0027s mm (even though init hasn\u0027t\nbeen created yet, its mm is the static init_mm).\n\nThe other feature is how the kernel handles the page table which\ndescribes the portion of the address space which is only visible when\nexecuting inside the kernel, and which is shared by all threads. On\nthe SH4 the only portion of the kernel\u0027s address space which described\nusing the page table is called P3, from 0xc0000000 to 0xdfffffff. This\nportion of the address space is divided into three:\n - mappings for dma_alloc_coherent()\n - mappings for vmalloc() and ioremap()\n - fixmap mappings, primarily used in copy_user_pages() to create\n kernel mappings of user pages with the correct cache colour.\n\nTo optimise the TLB miss handler we don\u0027t want to add an additional\ncondition which checks whether the faulting address is in the user or\nthe kernel portion of the address space, and so all page tables have a\ncommon portion which describes the kernel part of the address\nspace. As the SH4 uses a two level page table, only the kernel portion\nof first level page table (the pgd entries) is duplicated. These all\npoint to the same second level entries (the pte\u0027s), and so no memory\nis wasted.\n\nThe reference page table for the kernel is called the swapper_pg_dir,\nand when a new page table is created for a new process the kernel\nportion of the page table is copied from swapper_pg_dir. This works\nfine when changes only occur in the second level of the kernel\u0027s page\ntable, or the first level entries are created before any new user\nprocesses. However if a change occurs to the first level of the page\ntable, and there are existing processes which don\u0027t have this entry in\ntheir page table, this new entry needs to be added. This is done on\ndemand, when the kernel accesses a P3 address which isn\u0027t mapped using\nthe current page table, the code in vmalloc_fault() copies the entry\nfrom the reference page table (swapper_pg_dir) into the current\nprocesses page table.\n\nThe bug which this patch addresses is that the code in vmalloc_fault()\nwas not copying addresses which fell in the dma_alloc_coherent()\nportion of the address space, and it should have been copying any P3\naddress.\n\nWhy we hadn\u0027t seen this before, and what made this hard to reproduce,\nis that normally the kernel will have called dma_alloc_coherent(), and\naccessed the memory mapping created, before any user process\nruns. Typically drivers such as USB or SATA will have created and used\nmappings of this type during the kernel initialisation, when probing\nfor the attached devices, before init runs. Ethernet is slightly\ndifferent, as it normally only creates and accesses\ndma_alloc_coherent() mappings when the network is brought up, but if\nkernel level IP configuration is used this will also occur before any\nuser space process runs. So the first reproduction of this problem\nwhich we saw was occurred when USB and SATA were removed from the\nkernel, and then bring up Ethernet from user space using ifconfig.\nI\u0027d like to thank Joseph Bormolini who did the hard work reducing the\nproblem to this simple to reproduce criteria.\n\nIn your case the situation is slightly different, and turns out to\ndepends on the exact kernel configuration (which we had) and your\nramdisk contents (which we didn\u0027t - hence the need for some assumptions).\n\nIn this case the problem is a side effect of kernel level module\nloading. Kernel subsystems sometimes trigger the load of kernel\nmodules directly, for example the crypto subsystem tries to load the\ncryptomgr and MTD tries to load modules for Flash partitioning if\nthese are not built into the kernel. This is done by the kernel\ncreating a user process which runs insmod to try and load the\nappropriate module.\n\nIn order for this to cause problems the system must be running with a\ninitrd or initramfs, which contains an insmod executable - if the\nkernel can\u0027t find an insmod to run, no user process is created, and\nthe problem doesn\u0027t occur. If an insmod is found, a process is\ncreated to run it, which will inherit the kernel portion of the\nswapper_pg_dir first level page table. It doesn\u0027t matter whether the\ninmod is successful or not, but when the the kernel scheduler context\nswitches back to the kernel initialisation thread, the insmod\u0027s mm is\n\u0027borrowed\u0027 by the kernel thread, as it doesn\u0027t have an address space\nof its own. (Reference counting is used to ensure this mm is not\ndestroyed, even though the user process which caused its creation may no\nlonger exist.)

There exist\n more than one function for allocating and freeing the buffers:\n currently these 3 are used dma_{alloc, free}_coherent,\n dma_{alloc,free}_writecombine, dma_{alloc,free}_noncoherent.\n\n For most of the systems these calls are almost equivalent and can be\n interchanged. For others, especially the truly non-coherent ones\n (like ARM), the difference can be easily noticed in overall driver\n performance. Sadly not all architectures provide implementations for\n all of them, so the drivers might need to be adapted and cannot be\n easily shared between different architectures. The provided patches\n unify all these functions and hide the differences under the already\n existing dma attributes concept. The thread with more references is\n available here:\n\n http://www.spinics.net/lists/linux-sh/msg09777.html\n\n These patches are also a prerequisite for unifying DMA-mapping\n implementation on ARM architecture with the common one provided by\n dma_map_ops structure and extending it with IOMMU support. More\n information is available in the following thread:\n\n http://thread.gmane.org/gmane.linux.kernel.cross-arch/12819\n\n More works on dma-mapping framework are planned, especially in the\n area of buffer sharing and managing the shared mappings (together with\n the recently introduced dma_buf interface: commit d15bd7ee445d\n \"dma-buf: Introduce dma buffer sharing mechanism\").\n\n The patches in the current set introduce a new alloc/free methods\n (with support for memory attributes) in dma_map_ops structure, which\n will later replace dma_alloc_coherent and dma_alloc_writecombine\n functions.\"\n\nPeople finally started piping up with support for merging this, so I\u0027m\nmerging it as the last of the pending stuff from the merge window.\nLooks like pohmelfs is going to wait for 3.5 and more external support\nfor merging.\n\n* \u0027for-linus\u0027 of git://git.linaro.org/people/mszyprowski/linux-dma-mapping:\n common: DMA-mapping: add

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "6ae6650232ddcf2f50e8817acd63cde37cf1d093", "tree": "0f60b6501f0c5efd2fdf4c997b54004bc91f3df1", "parents": [ "4bea3418c737891894b9d3d3e9f8bbd67d66fa38" ], "author": { "name": "Matt Fleming", "email": "matt@console-pimps.org", "time": "Mon Mar 29 15:24:54 2010 +0900" }, "committer": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Mon Mar 29 15:24:54 2010 +0900" }, "message": "sh: tlb debugfs support.\n\nExport the status of the utlb and itlb entries through debugfs.\n\nSigned-off-by: Matt Fleming \u003cmatt@console-pimps.org\u003e\nSigned-off-by: Paul Mundt \u003clethal@linux-sh.org\u003e\n" }, { "commit": "4539282dbc20fe612113c8f267d51a90d46a7f50", "tree": "579f4785bd2e06339291df2c1d17c0b7be93df0c", "parents": [ "01e77706cdde7c0b47e5ca1f4284a795504c7c40" ], "author": { "name": "Matt Fleming", "email": "matt@console-pimps.org", "time": "Fri Mar 26 11:37:16 2010 +0900" }, "committer": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Fri Mar 26 11:37:16 2010 +0900" }, "message": "sh: update the TLB replacement counter for entry wiring.\n\nPresently the TLB wiring code depends on MMUCR.URB for working out where\nto place the wired entry, but fails to take the replacment counter in to\nconsideration.
