      "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"

Here is an attempt to clean it all up.\n\nIn order to find all possibly affected files, I searched for all\nfiles including \u003clinux/pci.h\u003e but without any other occurence of \"pci\"\nor \"PCI\". I removed the include statement from all of these, then I\ncompiled an allmodconfig kernel on both i386 and x86_64 and fixed the\nfalse positives manually.\n\nMy tests covered 66% of the affected files, so there could be false\npositives remaining. Untested files are:\n\narch/alpha/kernel/err_common.c\narch/alpha/kernel/err_ev6.c\narch/alpha/kernel/err_ev7.c\narch/ia64/sn/kernel/huberror.c\narch/ia64/sn/kernel/xpnet.c\narch/m68knommu/kernel/dma.c\narch/mips/lib/iomap.c\narch/powerpc/platforms/pseries/ras.c\narch/ppc/8260_io/enet.c\narch/ppc/8260_io/fcc_enet.c\narch/ppc/8xx_io/enet.c\narch/ppc/syslib/ppc4xx_sgdma.c\narch/sh64/mach-cayman/iomap.c\narch/xtensa/kernel/xtensa_ksyms.c\narch/xtensa/platform-iss/setup.c\ndrivers/i2c/busses/i2c-at91.c\ndrivers/i2c/busses/i2c-mpc.c\ndrivers/media/video/saa711x.c\ndrivers/misc/hdpuftrs/hdpu_cpustate.c\ndrivers/misc/hdpuftrs/hdpu_nexus.c\ndrivers/net/au1000_eth.c\ndrivers/net/fec_8xx/fec_main.c\ndrivers/net/fec_8xx/fec_mii.c\ndrivers/net/fs_enet/fs_enet-main.c\ndrivers/net/fs_enet/mac-fcc.c\ndrivers/net/fs_enet/mac-fec.c\ndrivers/net/fs_enet/mac-scc.c\ndrivers/net/fs_enet/mii-bitbang.c\ndrivers/net/fs_enet/mii-fec.c\ndrivers/net/ibm_emac/ibm_emac_core.c\ndrivers/net/lasi_82596.c\ndrivers/parisc/hppb.c\ndrivers/sbus/sbus.c\ndrivers/video/g364fb.c\ndrivers/video/platinumfb.c\ndrivers/video/stifb.c\ndrivers/video/valkyriefb.c\ninclude/asm-arm/arch-ixp4xx/dma.h\nsound/oss/au1550_ac97.c\n\nI would welcome test reports for these files.

      "message": "IRQ: Maintain regs pointer globally rather than passing to IRQ handlers\n\nMaintain a per-CPU global \"struct pt_regs *\" variable which can be used instead\nof passing regs around manually through all ~1800 interrupt handlers in the\nLinux kernel.\n\nThe regs pointer is used in few places, but it potentially costs both stack\nspace and code to pass it around.  On the FRV arch, removing the regs parameter\nfrom all the genirq function results in a 20% speed up of the IRQ exit path\n(ie: from leaving timer_interrupt() to leaving do_IRQ()).\n\nWhere appropriate, an arch may override the generic storage facility and do\nsomething different with the variable.  On FRV, for instance, the address is\nmaintained in GR28 at all times inside the kernel as part of general exception\nhandling.\n\nHaving looked over the code, it appears that the parameter may be handed down\nthrough up to twenty or so layers of functions.  Consider a USB character\ndevice attached to a USB hub, attached to a USB controller that posts its\ninterrupts through a cascaded auxiliary interrupt controller.  A character\ndevice driver may want to pass regs to the sysrq handler through the input\nlayer which adds another few layers of parameter passing.\n\nI\u0027ve build this code with allyesconfig for x86_64 and i386.  I\u0027ve runtested the\nmain part of the code on FRV and i386, though I can\u0027t test most of the drivers.\nI\u0027ve also done partial conversion for powerpc and MIPS - these at least compile\nwith minimal configurations.\n\nThis will affect all archs.  Mostly the changes should be relatively easy.\nTake do_IRQ(), store the regs pointer at the beginning, saving the old one:\n\n\tstruct pt_regs *old_regs \u003d set_irq_regs(regs);\n\nAnd put the old one back at the end:\n\n\tset_irq_regs(old_regs);\n\nDon\u0027t pass regs through to generic_handle_irq() or __do_IRQ().\n\nIn timer_interrupt(), this sort of change will be necessary:\n\n\t-\tupdate_process_times(user_mode(regs));\n\t-\tprofile_tick(CPU_PROFILING, regs);\n\t+\tupdate_process_times(user_mode(get_irq_regs()));\n\t+\tprofile_tick(CPU_PROFILING);\n\nI\u0027d like to move update_process_times()\u0027s use of get_irq_regs() into itself,\nexcept that i386, alone of the archs, uses something other than user_mode().\n\nSome notes on the interrupt handling in the drivers:\n\n (*) input_dev() is now gone entirely.  The regs pointer is no longer stored in\n     the input_dev struct.\n\n (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.  It does\n     something different depending on whether it\u0027s been supplied with a regs\n     pointer or not.\n\n (*) Various IRQ handler function pointers have been moved to type\n     irq_handler_t.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\n(cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)\n"
