On some archs, dump_stack() prints\nextra information - pid, utsname and so on - in addition to the\nbacktrace while the two are identical on other archs.\n\nThe usages in arch-independent code of the two functions indicate\nshow_stack(NULL, NULL) should print out bare backtrace while\ndump_stack() is used for debugging purposes when something went wrong,\nso it does make sense to print additional information on the task which\ntriggered dump_stack().\n\nThere\u0027s no reason to require archs to implement two separate but mostly\nidentical functions. It leads to unnecessary subtle information.\n\nThis patch expands the dummy fallback dump_stack() implementation in\nlib/dump_stack.c such that it prints out debug information (taken from\nx86) and invokes show_stack(NULL, NULL) and drops arch-specific\ndump_stack() implementations in all archs except blackfin. Blackfin\u0027s\ndump_stack() does something wonky that I don\u0027t understand.\n\nDebug information can be printed separately by calling\ndump_stack_print_info() so that arch-specific dump_stack()\nimplementation can still emit the same debug information. This is used\nin blackfin.\n\nThis patch brings the following behavior changes.\n\n* On some archs, an extra level in backtrace for show_stack() could be\n printed. This is because the top frame was determined in\n dump_stack() on those archs while generic dump_stack() can\u0027t do that\n reliably. It can be compensated by inlining dump_stack() but not\n sure whether that\u0027d be necessary.\n\n* Most archs didn\u0027t use to print debug info on dump_stack(). They do\n now.\n\nAn example WARN dump follows.\n\n WARNING: at kernel/workqueue.c:4841 init_workqueues+0x35/0x505()\n Hardware name: empty\n Modules linked in:\n CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.9.0-rc1-work+ #9\n 0000000000000009 ffff88007c861e08 ffffffff81c614dc ffff88007c861e48\n ffffffff8108f50f ffffffff82228240 0000000000000040 ffffffff8234a03c\n 0000000000000000 0000000000000000 0000000000000000 ffff88007c861e58\n Call Trace:\n [\u003cffffffff81c614dc\u003e] dump_stack+0x19/0x1b\n [\u003cffffffff8108f50f\u003e] warn_slowpath_common+0x7f/0xc0\n [\u003cffffffff8108f56a\u003e] warn_slowpath_null+0x1a/0x20\n [\u003cffffffff8234a071\u003e] init_workqueues+0x35/0x505\n ...\n\nv2: CPU number added to the generic debug info as requested by s390\n folks and dropped the s390 specific dump_stack().

Because linkage is per objecct file,\n dump_stack_print_info() living in the same lib file as generic\n dump_stack() means that archs which implement custom dump_stack()\n - at this point, only blackfin - can\u0027t use dump_stack_print_info()\n as that will bring in the generic version of dump_stack() too. v1\n The v1 patch broke build on blackfin due to this issue.

On closer inspection issues were found in the DMA\ndebug API and how it handled multiple mappings of the same buffer.\n\nThe issue I found is the fact that the debug_dma_mapping_error would\nonly set the map_err_type to MAP_ERR_CHECKED in the case that the was\nonly one match for device and device address. However in the case of\nnon-IOMMU, multiple addresses existed and as a result it was not setting\nthis field once a second mapping was instantiated. I have resolved this\nby changing the search so that it instead will now set MAP_ERR_CHECKED\non the first buffer that matches the device and DMA address that is\ncurrently in the state MAP_ERR_NOT_CHECKED.\n\nA secondary side effect of this patch is that in the case of multiple\nbuffers using the same address only the last mapping will have a valid\nmap_err_type. The previous mappings will all end up with map_err_type\nset to MAP_ERR_CHECKED because of the dma_mapping_error call in\ndebug_dma_map_page. However this behavior may be preferable as it means\nyou will likely only see one real error per multi-mapped buffer, versus\nthe current behavior of multiple false errors mer multi-mapped buffer.\n\nSigned-off-by: Alexander Duyck \u003calexander.h.duyck@intel.com\u003e\nCc: Joerg Roedel \u003cjoro@8bytes.org\u003e\nReviewed-by: Shuah Khan \u003cshuah.khan@hp.com\u003e\nTested-by: Shuah Khan \u003cshuah.khan@hp.com\u003e\nCc: Jakub Kicinski \u003ckubakici@wp.pl\u003e\nCc: Konrad Rzeszutek Wilk \u003ckonrad.wilk@oracle.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "8d640a51ec9e9cdefa680b67ad55f933eefc5923", "tree": "c8e8964a54f42a529fceb6ef80590592d13bf68d", "parents": [ "0ef1594c017521ea89278e80fe3f80dafb17abde" ], "author": { "name": "Alexander Duyck", "email": "alexander.h.duyck@intel.com", "time": "Fri Mar 22 15:04:48 2013 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 22 16:41:20 2013 -0700" }, "message": "dma-debug: fix locking bug in check_unmap()\n\nIn check_unmap() it is possible to get into a dead-locked state if\ndma_mapping_error is called.

In particular, rather than estimating how\n much memory we will need for page tables and then build them into that\n memory -- a calculation that has shown to be incredibly fragile -- we\n now build them (on 64 bits) with the aid of a \"pseudo-linear mode\" --\n a #PF handler which creates temporary page tables on demand.\n\n This has several advantages:\n\n 1. It makes it much easier to support things that need access to data\n very early (a followon patchset uses this to load microcode way\n early in the kernel startup).\n\n 2. It allows the kernel and all the kernel data objects to be invoked\n from above the 4 GB limit. This allows kdump to work on very large\n systems.\n\n 3. It greatly reduces the difference between Xen and native (Xen\u0027s\n equivalent of the #PF handler are the temporary page tables created\n by the domain builder), eliminating a bunch of fragile hooks.\n\n The patch series also gets us a bit closer to W^X.\n\n Additional work in this pull is the 64-bit get_user() work which you\n were also involved with, and a bunch of cleanups/speedups to\n __phys_addr()/__pa().\"\n\n* \u0027x86-mm-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (105 commits)\n x86, mm: Move reserving low memory later in initialization\n x86, doc: Clarify the use of asm(\"%edx\") in uaccess.h\n x86, mm: Redesign get_user with a __builtin_choose_expr hack\n x86: Be consistent with data size in getuser.S\n x86, mm: Use a bitfield to mask nuisance get_user() warnings\n x86/kvm: Fix compile warning in kvm_register_steal_time()\n x86-32: Add support for 64bit get_user()\n x86-32, mm: Remove reference to alloc_remap()\n x86-32, mm: Remove reference to resume_map_numa_kva()\n x86-32, mm: Rip out x86_32 NUMA remapping code\n x86/numa: Use __pa_nodebug() instead\n x86: Don\u0027t panic if can not alloc buffer for swiotlb\n mm: Add alloc_bootmem_low_pages_nopanic()\n x86, 64bit, mm: hibernate use generic mapping_init\n x86, 64bit, mm: Mark data/bss/brk to nx\n x86: Merge early kernel reserve for 32bit and 64bit\n x86: Add Crash kernel low reservation\n x86, kdump: Remove crashkernel range find limit for 64bit\n memblock: Add memblock_mem_size()\n x86, boot: Not need to check setup_header version for setup_data\n ...\n" }, { "commit": "7c2db36e730ee4facd341679ecb21ee73ba92831", "tree": "75016fba72aaf0581b9263f7fa4c565e6e634f3c", "parents": [ "8b5628ab83b671f96ac9f174c1bd51c92589fc82", "a47a376f1c025e23e836c0376813c0424de665c2" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Feb 21 17:38:49 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Feb 21 17:38:49 2013 -0800" }, "message": "Merge branch \u0027akpm\u0027 (incoming from Andrew)\n\nMerge misc patches from Andrew Morton:\n\n - Florian has vanished so I appear to have become fbdev maintainer\n again :(\n\n - Joel and Mark are distracted to welcome to the new OCFS2 maintainer\n\n - The backlight queue\n\n - Small core kernel changes\n\n - lib/ updates\n\n - The rtc queue\n\n - Various random bits\n\n* akpm: (164 commits)\n rtc: rtc-davinci: use devm_*() functions\n rtc: rtc-max8997: use devm_request_threaded_irq()\n rtc: rtc-max8907: use devm_request_threaded_irq()\n rtc: rtc-da9052: use devm_request_threaded_irq()\n rtc: rtc-wm831x: use devm_request_threaded_irq()\n rtc: rtc-tps80031: use devm_request_threaded_irq()\n rtc: rtc-lp8788: use devm_request_threaded_irq()\n rtc: rtc-coh901331: use devm_clk_get()\n rtc: rtc-vt8500: use devm_*() functions\n rtc: rtc-tps6586x: use devm_request_threaded_irq()\n rtc: rtc-imxdi: use devm_clk_get()\n rtc: rtc-cmos: use dev_warn()/dev_dbg() instead of printk()/pr_debug()\n rtc: rtc-pcf8583: use dev_warn() instead of printk()\n rtc: rtc-sun4v: use pr_warn() instead of printk()\n rtc: rtc-vr41xx: use dev_info() instead of printk()\n rtc: rtc-rs5c313: use pr_err() instead of printk()\n rtc: rtc-at91rm9200: use dev_dbg()/dev_err() instead of printk()/pr_debug()\n rtc: rtc-rs5c372: use dev_dbg()/dev_warn() instead of printk()/pr_debug()\n rtc: rtc-ds2404: use dev_err() instead of printk()\n rtc: rtc-efi: use dev_err()/dev_warn()/pr_err() instead of printk()\n ...\n" }, { "commit": "5dc49c75a26b99e86a18441e0b64c1f7c7c6a500", "tree": "c3c142d3c43785a753ab987a92961fa0fbf7e188", "parents": [ "64dbfb444c150f5b64979323a197dedc2ec3e02c" ], "author": { "name": "Florian Fainelli", "email": "florian@openwrt.org", "time": "Thu Feb 21 16:44:12 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Feb 21 17:22:26 2013 -0800" }, "message": "decompressors: make the default XZ_DEC_* config match the selected architecture\n\nChange the defautl XZ_DEC_* config symbol to match the configured\narchitecture.

However, one issue that keeps popping up is\nits lack of a specific error code to determine which of the steps that\nit performs failed. Furthermore, while the function gives an example and\nsuggests what error code to return on failure, a wide variety of error\ncodes are used throughout the tree.\n\nIn an attempt to fix these problems, this patch adds a new function that\ndrivers can transition to. The devm_ioremap_resource() returns a pointer\nto the remapped I/O memory on success or an ERR_PTR() encoded error code\non failure. Callers can check for failure using IS_ERR() and determine\nits cause by extracting the error code using PTR_ERR().\n\ndevm_request_and_ioremap() is implemented as a wrapper around the new\nAPI and return NULL on failure as before. This ensures that backwards\ncompatibility is maintained until all users have been converted to the\nnew API, at which point the old devm_request_and_ioremap() function\nshould be removed.\n\nA semantic patch is included which can be used to convert from the old\ndevm_request_and_ioremap() API to the new devm_ioremap_resource() API.\nSome non-trivial cases may require manual intervention, though.\n\nSigned-off-by: Thierry Reding \u003cthierry.reding@avionic-design.de\u003e\nCc: Arnd Bergmann \u003carnd@arndb.de\u003e\nAcked-by: Dmitry Torokhov \u003cdmitry.torokhov@gmail.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n" }, { "commit": "373d4d099761cb1f637bed488ab3871945882273", "tree": "954bef7bc724aee105dd246d5f2b1ea04ed38b20", "parents": [ "64748a2c9062da0c32b59c1b368a86fc4613b1e1" ], "author": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Mon Jan 21 17:17:39 2013 +1030" }, "committer": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Mon Jan 21 17:17:57 2013 +1030" }, "message": "taint: add explicit flag to show whether lock dep is still OK.\n\nFix up all callers as they were before, with make one change: an\nunsigned module taints the kernel, but doesn\u0027t turn off lockdep.\n\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\n" }, { "commit": "226364766f936d249e408de03821468c1bf11dda", "tree": "3b4feabb40a87f311ae92bb973c18293d05597e8", "parents": [ "3a142ed962958d3063f648738a3384ab90017100", "1fb9341ac34825aa40354e74d9a2c69df7d2c304" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Jan 20 16:44:28 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Jan 20 16:44:28 2013 -0800" }, "message": "Merge tag \u0027fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux\n\nPull module fixes and a virtio block fix from Rusty Russell:\n \"Various minor fixes, but a slightly more complex one to fix the\n per-cpu overload problem introduced recently by kvm id changes.\"\n\n* tag \u0027fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux:\n module: put modules in list much earlier.\n module: add new state MODULE_STATE_UNFORMED.\n module: prevent warning when finit_module a 0 sized file\n virtio-blk: Don\u0027t free ida when disk is in use\n" }, { "commit": "4f73bc4dd3e8563ef4109f293a092820dff66d92", "tree": "8ebd5d01abaceb70da1932db1a5e7219630b0fd3", "parents": [ "a1bf9584429d61b7096f93ae09325e1ba538e9e8" ], "author": { "name": "Joe Millenbach", "email": "jmillenbach@gmail.com", "time": "Thu Jan 17 22:44:22 2013 -0800" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Fri Jan 18 16:15:27 2013 -0800" }, "message": "tty: Added a CONFIG_TTY option to allow removal of TTY\n\nThe option allows you to remove TTY and compile without errors.
