2011-02-19genirq: Remove default magicThomas Gleixner
Now that everything uses the wrappers, we can remove the default functions. None of those functions is performance critical. That makes the IRQ_MASKED flag tracking fully consistent. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2011-02-19genirq: Consolidate startup/shutdown of interruptsThomas Gleixner
Aside of duplicated code some of the startup/shutdown sites do not handle the MASKED/DISABLED flags and the depth field at all. Move that to a helper function and take care of it there.

2011-02-19genirq: Remove bogus conditionalThomas Gleixner

2011-02-19genirq: Mark polled irqs and defer the real handlerThomas Gleixner
With the chip.end() function gone we might run into a situation where a poll call runs and the real interrupt comes in, sees IRQ_INPROGRESS and disables the line. That might be a perfect working one, which will then be masked forever. So mark them polled while the poll runs. When the real handler sees IRQ_INPROGRESS it checks the poll flag and waits for the polling to complete. Add the necessary amount of sanity checks to it to avoid deadlocks.

2011-02-19genirq: spurious: Run only one poller at a timeThomas Gleixner
No point in running concurrent pollers which confuse each other by setting PENDING. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-02-19genirq: Do not poll disabled, percpu and timer interruptsThomas Gleixner
There is no point in polling disabled lines. percpu does not make sense at all because we only poll on the cpu we're currently running on. Also polling per_cpu interrupts is racy as hell. The handler runs without locking so we might get a huge surprise. If the timer interrupt needs polling, then we wont get there anyway. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-02-19genirq: Fixup poll handlingThomas Gleixner
try_one_irq() contains redundant code and lots of useless checks for shared interrupts. Check for shared before setting IRQ_INPROGRESS and then call handle_IRQ_event() while pending. Shorter version with the same functionality. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-02-19genirq: Warn when handler enables interruptsThomas Gleixner
We run all handlers with interrupts disabled and expect them not to enable them. Warn when we catch one who does. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-02-19genirq: Plug race in report_bad_irq()Thomas Gleixner
We cannot walk the action chain unlocked. Even if IRQ_INPROGRESS is set an action can be removed and we follow a null pointer. It's safe to take the lock there, because the code which removes the action will call synchronize_irq() which waits unlocked for IRQ_INPROGRESS going away.

2011-02-19genirq: Remove redundant thread affinity settingThomas Gleixner
Thread affinity is already set by setup_affinity(). Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-02-19genirq: Do not copy affinity before setThomas Gleixner
While rumaging through arch code I found that there are a few workarounds which deal with the fact that the initial affinity setting from request_irq() copies the mask into irq_data->affinity before the chip code is called. In the normal path we unconditionally copy the mask when the chip code returns 0. Copy after the code is called and add a return code IRQ_SET_MASK_OK_NOCOPY for the chip functions, which prevents the copy. That way we see the real mask when the chip function decided to truncate it further as some arches do. IRQ_SET_MASK_OK is 0, which is the current behaviour. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-02-19genirq: Always apply cpu online maskThomas Gleixner
If the affinity had been set by the user, then a later request_irq() will honour that setting. But online cpus can have changed. So apply the online mask and for this case as well. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-02-19genirq: Rremove redundant checkThomas Gleixner
IRQ_NO_BALANCING is already checked in irq_can_set_affinity() above, no need to check it again. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-02-19genirq: Simplify affinity related codeThomas Gleixner
There is lot of #ifdef CONFIG_GENERIC_PENDING_IRQ along with duplicated code in the irq core. Move the #ifdeffery into one place and cleanup the code so it's readable. No functional change. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-02-19genirq: Namespace cleanupThomas Gleixner
The irq namespace has become quite convoluted. My bad. Clean it up and deprecate the old functions. All new functions follow the scheme: irq number based: irq_set/get/xxx/_xxx(unsigned int irq, ...) irq_data based: irq_data_set/get/xxx/_xxx(struct irq_data *d, ....) irq_desc based: irq_desc_get_xxx(struct irq_desc *desc) Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-02-19genirq: Add missing buslock to set_irq_type(), set_irq_wake()Thomas Gleixner
chips behind a slow bus cannot update the chip under desc->lock, but we miss the chip_buslock/chip_bus_sync_unlock() calls around the set type and set wake functions. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-02-19genirq: Make nr_irqs runtime expandableThomas Gleixner
We face more and more the requirement to expand nr_irqs at runtime. The reason are irq expanders which can not be detected in the early boot stage. So we speculate nr_irqs to have enough room. Further Xen needs extra irq numbers and we really want to avoid adding more "detection" code into the early boot. There is no real good reason why we need to limit nr_irqs at early boot. Allow the allocation code to expand nr_irqs. We have already 8k extra number space in the allocation bitmap, so lets use it. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2011-02-19genirq: Disable the SHIRQ_DEBUG call in request_threaded_irq for nowThomas Gleixner
With CONFIG_SHIRQ_DEBUG=y we call a newly installed interrupt handler in request_threaded_irq(). The original implementation (commit a304e1b8) called the handler _BEFORE_ it was installed, but that caused problems with handlers calling disable_irq_nosync(). See commit 377bf1e4. It's braindead in the first place to call disable_irq_nosync in shared handlers, but .... Moving this call after we installed the handler looks innocent, but it is very subtle broken on SMP. Interrupt handlers rely on the fact, that the irq core prevents reentrancy. Now this debug call violates that promise because we run the handler w/o the IRQ_INPROGRESS protection - which we cannot apply here because that would result in a possibly forever masked interrupt line. A concurrent real hardware interrupt on a different CPU results in handler reentrancy and can lead to complete wreckage, which was unfortunately observed in reality and took a fricking long time to debug. Leave the code here for now. We want this debug feature, but that's not easy to fix. We really should get rid of those disable_irq_nosync() abusers and remove that function completely.

2011-02-19genirq: Prevent access beyond allocated_irqs bitmapThomas Gleixner
Lars-Peter Clausen pointed out: I stumbled upon this while looking through the existing archs using SPARSE_IRQ. Even with SPARSE_IRQ the NR_IRQS is still the upper limit for the number of IRQs. Both PXA and MMP set NR_IRQS to IRQ_BOARD_START, with IRQ_BOARD_START being the number of IRQs used by the core. In various machine files the nr_irqs field of the ARM machine defintion struct is then set to "IRQ_BOARD_START + NR_BOARD_IRQS". As a result "nr_irqs" will greater then NR_IRQS which then again causes the "allocated_irqs" bitmap in the core irq code to be accessed beyond its size overwriting unrelated data. The core code really misses a sanity check there. This went unnoticed so far as by chance the compiler/linker places data behind that bitmap which gets initialized later on those affected platforms. So the obvious fix would be to add a sanity check in early_irq_init() and break all affected platforms. Though that check wants to be backported to stable as well, which will require to fix all known problematic platforms and probably some more yet not known ones as well. Lots of churn. A way simpler solution is to allocate a slightly larger bitmap and avoid the whole churn w/o breaking anything. Add a few warnings when an arch returns utter crap.

Biderman and Michal Hocko reported various memory corruptions that we suspected to be related to a LIST head located on stack, that was manipulated after thread left function frame (and eventually exited, so its stack was freed and reused).

2011-02-18Expand CONFIG_DEBUG_LIST to several other list operationsLinus Torvalds
When list debugging is enabled, we aim to readably show list corruption errors, and the basic list_add/list_del operations end up having extra debugging code in them to do some basic validation of the list entries. However, "list_del_init()" and "list_move[_tail]()" ended up avoiding the debug code due to how they were written. This fixes that. So the _next_ time we have list_move() problems with stale list entries, we'll hopefully have an easier time finding them.. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

There is a double completion associated with error handling for RC QPs.
