      "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"

      "message": "[PATCH] powerpc: fix trigger handling in the new irq code\n\nThis patch slightly reworks the new irq code to fix a small design error.  I\nremoved the passing of the trigger to the map() calls entirely, it was not a\ngood idea to have one call do two different things.  It also fixes a couple of\ncorner cases.\n\nMapping a linux virtual irq to a physical irq now does only that.  Setting the\ntrigger is a different action which has a different call.\n\nThe main changes are:\n\n- I no longer call host-\u003eops-\u003emap() for an already mapped irq, I just return\n  the virtual number that was already mapped.  It was called before to give an\n  opportunity to change the trigger, but that was causing issues as that could\n  happen while the interrupt was in use by a device, and because of the\n  trigger change, map would potentially muck around with things in a racy way.\n   That was causing much burden on a given\u0027s controller implementation of\n  map() to get it right.  This is much simpler now.  map() is only called on\n  the initial mapping of an irq, meaning that you know that this irq is _not_\n  being used.  You can initialize the hardware if you want (though you don\u0027t\n  have to).\n\n- Controllers that can handle different type of triggers (level/edge/etc...)\n  now implement the standard irq_chip-\u003eset_type() call as defined by the\n  generic code.  That means that you can use the standard set_irq_type() to\n  configure an irq line manually if you wish or (though I don\u0027t like that\n  interface), pass explicit trigger flags to request_irq() as defined by the\n  generic kernel interfaces.  Also, using those interfaces guarantees that\n  your controller set_type callback is called with the descriptor lock held,\n  thus providing locking against activity on the same interrupt (including\n  mask/unmask/etc...) automatically.  A result is that, for example, MPIC\u0027s\n  own map() implementation calls irq_set_type(NONE) to configure the hardware\n  to the default triggers.\n\n- To allow the above, the irq_map array entry for the new mapped interrupt\n  is now set before map() callback is called for the controller.\n\n- The irq_create_of_mapping() (also used by irq_of_parse_and_map()) function\n  for mapping interrupts from the device-tree now also call the separate\n  set_irq_type(), and only does so if there is a change in the trigger type.\n\n- While I was at it, I changed pci_read_irq_line() (which is the helper I\n  would expect most archs to use in their pcibios_fixup() to get the PCI\n  interrupt routing from the device tree) to also handle a fallback when the\n  DT mapping fails consisting of reading the PCI_INTERRUPT_PIN to know wether\n  the device has an interrupt at all, and the the PCI_INTERRUPT_LINE to get an\n  interrupt number from the device.  That number is then mapped using the\n  default controller, and the trigger is set to level low.  That default\n  behaviour works for several platforms that don\u0027t have a proper interrupt\n  tree like Pegasos.  If it doesn\u0027t work for your platform, then either\n  provide a proper interrupt tree from the firmware so that fallback isn\u0027t\n  needed, or don\u0027t call pci_read_irq_line()\n\n- Add back a bit that got dropped by my main rework patch for properly\n  clearing pending IPIs on pSeries when using a kexec\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "powerpc: Implement accurate task and CPU time accounting\n\nThis implements accurate task and cpu time accounting for 64-bit\npowerpc kernels.  Instead of accounting a whole jiffy of time to a\ntask on a timer interrupt because that task happened to be running at\nthe time, we now account time in units of timebase ticks according to\nthe actual time spent by the task in user mode and kernel mode.  We\nalso count the time spent processing hardware and software interrupts\naccurately.  This is conditional on CONFIG_VIRT_CPU_ACCOUNTING.  If\nthat is not set, we do tick-based approximate accounting as before.\n\nTo get this accurate information, we read either the PURR (processor\nutilization of resources register) on POWER5 machines, or the timebase\non other machines on\n\n* each entry to the kernel from usermode\n* each exit to usermode\n* transitions between process context, hard irq context and soft irq\n  context in kernel mode\n* context switches.\n\nOn POWER5 systems with shared-processor logical partitioning we also\nread both the PURR and the timebase at each timer interrupt and\ncontext switch in order to determine how much time has been taken by\nthe hypervisor to run other partitions (\"steal\" time).  Unfortunately,\nsince we need values of the PURR on both threads at the same time to\naccurately calculate the steal time, and since we can only calculate\nsteal time on a per-core basis, the apportioning of the steal time\nbetween idle time (time which we ceded to the hypervisor in the idle\nloop) and actual stolen time is somewhat approximate at the moment.\n\nThis is all based quite heavily on what s390 does, and it uses the\ngeneric interfaces that were added by the s390 developers,\ni.e. account_system_time(), account_user_time(), etc.\n\nThis patch doesn\u0027t add any new interfaces between the kernel and\nuserspace, and doesn\u0027t change the units in which time is reported to\nuserspace by things such as /proc/stat, /proc/\u003cpid\u003e/stat, getrusage(),\ntimes(), etc.  Internally the various task and cpu times are stored in\ntimebase units, but they are converted to USER_HZ units (1/100th of a\nsecond) when reported to userspace.  Some precision is therefore lost\nbut there should not be any accumulating error, since the internal\naccumulation is at full precision.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n"
