[PARISC] Make superio.c initialize before any driver needs it Convert superio_init to use PCI_FIXUP_FINAL as ohci_pci being called before superio_probe really makes a mess. superio_init will then fail to register irq 20 (the "SuperIO" irq) and BUG() because ohci_pci has stolen it before superio_fixup_irq can be moved USB to irq 1.

/* NOTES:
*
* Function 0 is an IDE controller. It is identical to a PC87415 IDE
* controller (and identifies itself as such).
*
* Function 1 is a "Legacy I/O" controller. Under this function is a
* whole mess of legacy I/O peripherals. Of course, HP hasn't enabled
* all the functionality in hardware, but the following is available:
*
* Two 16550A compatible serial controllers
* An IEEE 1284 compatible parallel port
* A floppy disk controller
*
* Function 2 is a USB controller.
*
* We must be incredibly careful during initialization. Since all
* interrupts are routed through function 1 (which is not allowed by
* the PCI spec), we need to program the PICs on the legacy I/O port
* *before* we attempt to set up IDE and USB. @#$!&
*
* According to HP, devices are only enabled by firmware if they have
* a physical device connected.
*
* Configuration register bits:
* 0x5A: FDC, SP1, IDE1, SP2, IDE2, PAR, Reserved, P92
* 0x5B: RTC, 8259, 8254, DMA1, DMA2, KBC, P61, APM

static irqreturn_t
IRQ: Maintain regs pointer globally rather than passing to IRQ handlers Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

parisc: remove IRQF_DISABLED People are playing odd games with IRQF_DISABLED, remove it. Its not reliable, since shared interrupt lines could disable it for you, and its possible and allowed for archs to disable IRQs to limit IRQ nesting. Therefore, simply mandate that _ALL_ IRQ handlers are run with IRQs disabled. [ This _should_ not break anything, since we've mandated that IRQ handlers _must_ be able to deal with this for a _long_ time ] IRQ handlers should be fast, no if buts and any other exceptions. We also have plenty instrumentation to find any offending IRQ latency sources.
