Hey guys, I really want to kill this thing. The only way to do that is to actually pass the pt_regs all the way down from the interrupt source. It would be a three step process: 1) Add pt_regs arg to serio_interrupt and serio->dev->interrupt() Update all serio->dev drivers and serio_interrupt() invokers. I've done this in the patch below. We must handle pt_regs being NULL, f.e. when the event is via a tty ldisc or a timer for which there is no "pt_regs" context to obtain. 2) At the input layer, push 'regs' down via input_event() into the handlers. Patch below does this as well. 3) Final step to complete this, convert USB to pass the pt_regs that the host controller interrupt receives down to the URB callbacks. This itself was also a multistep process: a) pass regs down from generic host controller layer to hcd driver b) pass regs from hcd driver into urb handler EHCI is problematic here, as it does the URB work in a tasklet :( we need to decide whether we can move the normal URB completion back into the hw interrupt handler or not I think it should be done, I'd basically have my thumbs up my butt if I didn't have Alt-SYSRQ-p register dumps available and that is what EHCI+usbkbd is currently. UHCI and OHCI both complete urbs in hw IRQ context so they are just fine. c) update urb handlers to take the regs arg, make hcd drivers pass it on in I was really bored, so this was also done in the patch below :) We get a USB cleanup for free because of this, a lot of people were defining their own ugly typedefs for what should be usb_complete_t so I fixed that up :-) I also caught a lot of usb_fill_*() call sites casting the completion function pointer to usb_complete_t so the compiler wouldn't help us find necessary fixup if we changed the args again :-( I think I got them all, someone bored should grep the tree for usb_complete_t and fixup any remaining spots where it is used in a cast. I tried to enable as many drivers as possible in a test build but it is possible I did miss a few obscure USB configs. So why do I want to kill kbd_pt_regs so badly? Well, first of all I have to walk through all kinds of hoops on sparc64 to update kbd_pt_regs properly on the USB controller interrupt and I've had a few cases where I had trouble tracking down some kernel bug because kbd_pt_regs could easily be inaccurate if another interrupt came in right after the keyboard USB one. Right now, kbd_pt_regs is not updated at all for USB keyboards on x86 rendering SYSRQ register dumps non-existent in such configurations. This forces it to happen, and because the regs are passed in the context in which the URB completes, it will always be accurate (it will even work properly if I have 5 USB keyboards :-) While doing this, I also noticed a bunch of ancient keyboard drivers in 2.5.x under drivers/char that need to be converted or deleted. They were still calling handle_scancode() !!! :-) drivers/tc has few as well. There is also a stray handle_scancode() reference in a include/asm-parisc/keyboard.h comment I tested this on sparc64 with an OHCI attached USB keyboard, and register dumping works fine etc. Here is just the USB bits.

Without this, time runs 50x too slow after resume, since nothing knows to tell the timer to re-initialize.

Here are a few fixes I needed when porting oprofile to ppc64: - __PAGE_OFFSET isnt defined for all architectures, use PAGE_OFFSET instead - include linux/cache.h everywhere we use ____cacheline_aligned etc. Otherwise we end up with a structure called ____cacheline_aligned and no alignment :(

This changes sys_getppid() to be more POSIX-threading conformant. sys_getppid() needs to return the PID of the "process' parent" (ie. the tgid of the parent thread), not the thread parent's PID. The patch has no effect on non-CLONE_THREAD users, for them current->group_leader == current. The effect on CLONE_THREAD threads is that getppid() does not return any PID within the thread group anymore. Plus if a threaded application starts up a (non-thread) child then the child sees the process PID of the parent process, not the thread PID of the parent thread. in theory we could introduce the getttid() variant to get to the TID of the parent thread, but i doubt it would be of any use. (and we can add it if the need arises.) The lockless algorithm is still safe because the ->group_leader pointer never changes asynchronously. (the ->real_parent pointer might still change asynchronously so the SMP checks are still needed.) I've also updated the comments (they referenced the nonexistent p_ooptr field.), plus i've changed the mb() to rmb() - we need to order the reads, we dont do any global writes that need some predictable ordering.

This fixes threaded coredumps and streamlines the code. The old code caused crashes and hung coredumps. The new code has been tested for some time already and appears to be robust. Changes: - the code now uses completions instead of a semaphore and a waitqueue, attached to mm_struct: /* coredumping support */ int core_waiters; struct completion *core_startup_done, core_done; - extended the completion concept with a 'complete all' call - all pending threads are woken up in that case. - core_waiters is a plain integer now - it's always accessed from under the mmap_sem. It's also used as the fastpath-check in the sys_exit() path, instead of ->dumpable (which was incorrect). - got rid of the ->core_waiter task flag - it's not needed anymore.
