The subsequent AD181x quirk patch would like this as part of the API. pnp_register_dependent_option() adds to the same dependent chain the quirk is walking which is fairly unclean. This enables a private option chain build which it can then just add onto the end when done.

In some places, we need to get the struct pnp_resource, not just the struct resource, because ISAPNP needs to store the register index in the pnp_resource. I don't like pnp_get_pnp_resource() and hope that it is temporary, but we need it for a little while.

This patch removes a use of "idx" in pnp_check_port() and similar functions, in preparation for replacing idx with a pointer to the resource itself. I split this out because it changes the behavior slightly: we used to check for conflicts only with earlier resources, e.g., we checked resource 2 against resources 0 and 1 but not against 3, 4, etc. Now we will check against all resources except 2. Since resources are assigned in ascending order, the old behavior was probably safe, but I don't like to depend on that ordering.

由 David Howells 提交于
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.

Most it does is the #if 0 of EXPORT_SYMBOL's, so if any modular code will use any of them, re-adding will be trivial. Modular ISAPnP might be interesting in some cases, but this is more legacy code. If someone would work on it to sort all the issues out (starting with the point that most users of __ISAPNP__ will have to be fixed) re-enabling the required EXPORT_SYMBOL's won't be hard for him.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
