      "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"

For some platforms, this is\ncritical to setup correctly, particularly those which the setting is dependent\non the device.\n\nCurrently, ARM drivers do (eg) the following:\n\n\terr \u003d request_irq(irq, ...);\n\n\tset_irq_type(irq, IRQT_RISING);\n\nHowever, if the interrupt has previously been programmed to be level sensitive\n(for whatever reason) then this will cause an interrupt storm.\n\nHence, if we combine set_irq_type() with request_irq(), we can then safely set\nthe type prior to unmasking the interrupt.  The unfortunate problem is that in\norder to support this, these flags need to be visible outside of the ARM\narchitecture - drivers such as smc91x need these flags and they\u0027re\ncross-architecture.\n\nFinally, the SA_TRIGGER_* flag passed to request_irq() should reflect the\nproperty that the device would like.
