This results in a deadlock in this scenario. cpu A holds clockevents_lock in clockevents_notify() with irqs enabled cpu B waits for clockevents_lock in clockevents_notify() with irqs disabled cpu C doing set_mtrr() which will try to rendezvous of all the cpus. This will result in C and A come to the rendezvous point and waiting for B. B is stuck forever waiting for the spinlock and thus not reaching the rendezvous point. Fix the clockevents code so that clockevents_lock is taken with interrupts disabled and thus avoid the above deadlock. Also call lapic_timer_propagate_broadcast() on the destination cpu so that we avoid calling smp_call_function() in the clockevents notifier chain. This issue left us wondering if we need to change the MTRR rendezvous logic to use stop machine logic (instead of smp_call_function) or add a check in spinlock debug code to see if there are other spinlocks which gets taken under both interrupts enabled/disabled conditions.

* | | | | tty: make sure to flush any pending work when halting the ldiscLinus Torvalds2009-08-25

As a result, if you get just the right timing, the pending work may be just about to execute (ie the timer has already triggered and thus cancel_delayed_work() was a no-op), when we then re-initialize the ldisc from under it. That, in turn, results in various random problems, usually seen as a NULL pointer dereference in run_timer_softirq() or a BUG() in worker_thread (but it can be almost anything). Fix it by adding the required 'flush_scheduled_work()' after doing the tty_ldisc_halt() (this also requires us to move the ldisc halt to before taking the ldisc mutex in order to avoid a deadlock with the workqueue executing do_tty_hangup, which requires the mutex). The locking should be cleaned up one day (the requirement to do this outside the ldisc_mutex is very annoying, and weakens the lock), but that's a larger and separate undertaking.

Data in descriptors is accessed simultaneously by the chip (writing status and size when a packet is received) and CPU (reading to check if the packet was received). This isn't a valid usage of PCI DMA API, which requires use of the coherent (consistent) memory for such purpose. Unfortunately e100 chips working in "simplified" RX mode have to store received data directly after the descriptor. Fixing the driver to conform to the API would require using unsupported "flexible" RX mode or receiving data into a coherent memory and using CPU to copy it to network buffers. This patch, while not yet making the driver conform to the PCI DMA API, allows it to work correctly on X86 with swiotlb (while not breaking other architectures).

But now the BSSID of AP we are trying to associate is only available after association is successful, and any attempt to associate without the needed flag doesn't work.

This also prevents an buffer underrun if failure occurred in the first iteration. yellowfin_open() which calls yellowfin_init_ring() should free its requested irq upon failure.

In the process of the removal event, the hidden raid componet is removed from the parent.When the disks is added back, the adding of the port fails becuase there is no instance of the device in its parent. To fix this issue, the driver needs to call mpt2sas_transport_update_links() prior to calling _scsih_add_device. In addition, we added sanity checks on volume add and removal to ignore events for foreign volumes.
