      "message": "include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h\n\npercpu.h is included by sched.h and module.h and thus ends up being\nincluded when building most .c files.  percpu.h includes slab.h which\nin turn includes gfp.h making everything defined by the two files\nuniversally available and complicating inclusion dependencies.\n\npercpu.h -\u003e slab.h dependency is about to be removed.  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"

(I don\u0027t know why, but\nI guess that there would be typical situation where the handler for\nmigration is needed, such as hotplug - the processor going to be\noffline/hot-removed.)\n\nTo shut up this warning, there are 2 way at least:\n a) fix CPEI stuff\n b) prohibit setting affinity to PER_CPU irq\n\nI\u0027m not sure what stuff of CPEI need to be fixed, but I think that\nreturning error to attempting move PER_CPU irq is useful for all\napplications since it will never work.\n\nFollowing small patch takes b) style.\nIt works, the warning disappeared and irqbalance still runs well.\n\nSigned-off-by: Hidetoshi Seto \u003cseto.hidetoshi@jp.fujitsu.com\u003e\nCc: Arjan van de Ven \u003carjan@infradead.org\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nAcked-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

This seemed to have originated from the way the write_proc\nfunction of the /proc filesystem operates.\n\nThis has been reworked to not use kmalloc and eliminates a lot of\nget_user() overhead by performing one access_ok before using __get_user().\n\nWe need to test if we are in kernel or user space (is_user) and access the\nbuffer differently.  We cannot use __get_user() to access kernel addresses\nin all cases, for example in architectures with separate address space for\nkernel and user.\n\nThis function will be useful for other uses as well; for example, taking\ninput for /sysfs instead of /proc, so it was changed to accept kernel\nbuffers.  We have this use for the Linux UWB project, as part as the\nupcoming bandwidth allocator code.\n\nOnly a few routines used this function and they were changed too.\n\nSigned-off-by: Reinette Chatre \u003creinette.chatre@linux.intel.com\u003e\nSigned-off-by: Inaky Perez-Gonzalez \u003cinaky@linux.intel.com\u003e\nCc: Paul Jackson \u003cpj@sgi.com\u003e\nCc: Joe Korty \u003cjoe.korty@ccur.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] genirq: rename desc-\u003ehandler to desc-\u003echip\n\nThis patch-queue improves the generic IRQ layer to be truly generic, by adding\nvarious abstractions and features to it, without impacting existing\nfunctionality.\n\nWhile the queue can be best described as \"fix and improve everything in the\ngeneric IRQ layer that we could think of\", and thus it consists of many\nsmaller features and lots of cleanups, the one feature that stands out most is\nthe new \u0027irq chip\u0027 abstraction.\n\nThe irq-chip abstraction is about describing and coding and IRQ controller\ndriver by mapping its raw hardware capabilities [and quirks, if needed] in a\nstraightforward way, without having to think about \"IRQ flow\"\n(level/edge/etc.) type of details.\n\nThis stands in contrast with the current \u0027irq-type\u0027 model of genirq\narchitectures, which \u0027mixes\u0027 raw hardware capabilities with \u0027flow\u0027 details.\nThe patchset supports both types of irq controller designs at once, and\nconverts i386 and x86_64 to the new irq-chip design.\n\nAs a bonus side-effect of the irq-chip approach, chained interrupt controllers\n(master/slave PIC constructs, etc.) are now supported by design as well.\n\nThe end result of this patchset intends to be simpler architecture-level code\nand more consolidation between architectures.\n\nWe reused many bits of code and many concepts from Russell King\u0027s ARM IRQ\nlayer, the merging of which was one of the motivations for this patchset.\n\nThis patch:\n\nrename desc-\u003ehandler to desc-\u003echip.\n\nOriginally i did not want to do this, because it\u0027s a big patch.  But having\nboth \"desc-\u003ehandler\", \"desc-\u003ehandle_irq\" and \"action-\u003ehandler\" caused a\nlarge degree of confusion and made the code appear alot less clean than it\ntruly is.\n\nI have also attempted a dual approach as well by introducing a\ndesc-\u003echip alias - but that just wasnt robust enough and broke\nfrequently.\n\nSo lets get over with this quickly.  The conversion was done automatically\nvia scripts and converts all the code in the kernel.\n\nThis renaming patch is the first one amongst the patches, so that the\nremaining patches can stay flexible and can be merged and split up\nwithout having some big monolithic patch act as a merge barrier.\n\n[akpm@osdl.org: build fix]\n[akpm@osdl.org: another build fix]\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

The same needs to be done for /proc/irq handling as well.\nOtherwise user space irq balancers are really not doing the right thing.\n\n- Changed pending_irq_balance_cpumask to pending_irq_migrate_cpumask for\n  lack of a generic name.\n- added move_irq out of IRQ_BALANCE, and added this same to X86_64\n- Added new proc handler for write, so we can do deferred write at irq\n  handling time.\n- Display of /proc/irq/XX/smp_affinity used to display CPU_MASKALL, instead\n  it now shows only active cpu masks, or exactly what was set.\n- Provided a common move_irq implementation, instead of duplicating\n  when using generic irq framework.\n\nTested on i386/x86_64 and ia64 with CONFIG_PCI_MSI turned on and off.\nTested UP builds as well.\n\nMSI testing: tbd: I have cards, need to look for a x-over cable, although I\ndid test an earlier version of this patch.
