* [PARISC] Add IRQ affinitiesJames Bottomley2005-11-173-5/+86
| | | | | | | | | | | | This really only adds them for the machines I can check SMP on, which is CPU interrupts and IOSAPIC (so not any of the GSC based machines). With this patch, irqbalanced can be used to maintain irq balancing. Unfortunately, irqbalanced is a bit x86 centric, so it doesn't do an incredibly good job, but it does work.

* [PARISC] Fix uniprocessor build by dummying smp_send_all_nop()Kyle McMartin2005-11-172-1/+7
| | | | | | | | Since irq.c uses smp_send_all_nop, we must define it for UP builds as well. Make it a static inline so it gets optimized away. This forces irq.c to include <asm/smp.h> though. Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
* [PARISC] Fix our interrupts not to use smp_call_functionJames Bottomley2005-11-173-15/+32
| | | | | | | | | | | | | Fix our interrupts not to use smp_call_function On K and D class smp, the generic code calls this under an irq spinlock, which causes the WARN_ON() message in smp_call_function() (and is also illegal because it could deadlock). The fix is to use a new scheme based on the IPI_NOP. Signed-off-by: James Bottomley <jejb@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
* [PARISC] Disable nesting of interruptsGrant Grundler2005-11-171-7/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Disable nesting of interrupts - still has holes The offending sequence starts out like this: 1) take external interrupt 2) set_eiem() to only allow TIMER_IRQ; local interrupts still disabled 3) read the EIRR to get a "list" of pending interrupts 4) clear EIRR of pending interrupts we intend to handle 5) call __do_IRQ() to handle IRQ. 6) handle_IRQ_event() enables local interrupts (I-Bit) 7) take a timer interrupt 8) read EIRR to get a new list of pending interrupts 9) clear EIRR of pending interrupts we just read 10) handle pending interrupts found in (8) 11) set_eiem(cpu_eiem) and return [ TROUBLE! all enabled CPU IRQs are unmasked. } 12) handle remaining interrupts pending from (3) e.g. call __do_IRQ() -> handle_IRQ_event()..etc [ TROUBLE! call to handle_IRQ_event() can now enable *any* IRQ. } 13) set_eiem(cpu_eiem) and return The problem is we now get into ugly race conditions with Timer and IPI interrupts at this point. I'm not exactly sure what happens when things go wrong (perhaps nest calls to IPI or timer interrupt?). But I'm certain it's not good. This sequence will break sooner if (10) would accidentally leave interrupts enabled. I'm pretty sure the right answer is now to make cpu_eiem a per CPU variable since all external interrupts on parisc are per CPU. This means we will NOT need to send an IPI to every CPU in the system when enabling or disabling an IRQ since only one CPU needs to change it's EIEM. Thanks to James Bottomley for (once again) pointing out the problem. Signed-off-by: Grant Grundler <grundler@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
* [PARISC] Make sure timer and IPI execute with interrupts disabledJames Bottomley2005-11-172-0/+6
| | | | | | | | | | | | | | | | | | | | | | Fix a longstanding smp bug The problem is that both the timer and ipi interrupts are being called with interrupts enabled, which isn't what anyone is expecting. The IPI issue has just started to show up by causing a BUG_ON in the slab debugging code. The timer issue never shows up because there's an eiem work around in our irq.c The fix is to label both these as SA_INTERRUPT which causes the generic irq code not to enable interrupts. I also suspect the smp_call_function timeouts we're seeing might be connected with the fact that we disable IPIs when handling any other type of interrupt. I've put a WARN_ON in the code for executing smp_call_function() with IPIs disabled. Signed-off-by: James Bottomley <jejb@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
* [PATCH] VM: fix zone list restart in page allocatateJens Axboe2005-11-171-3/+4
| | | | | | | | | We must reassign z before looping through the zones kicking kswapd, since it will be NULL if we hit an OOM condition and jump back to the beginning again. 'z' is initially assigned before the restart: label. So move the restart label up a little. Signed-off-by: Jens Axboe <axboe@suse.de>
