The code in io_apic.c and in i8259.c currently hardcode the same vector for the timer interrupt so there is no reason for a special assignment for the timer as the setup for the i8259 already takes care of this. Signed-off-by:

Currently assign_irq_vector works mostly by side effect and returns the results of it's changes to the caller. Which makes for a lot of arguments to pass/return and confusion as to what to do if you need the status but you aren't calling assign_irq_vector. This patch stops returning values from assign_irq_vector that can be retrieved just as easily by examining irq_cfg, and modifies the callers to retrive those values from irq_cfg when they need them.

Currently the io_apic.c has several parallel arrays for different kinds of data that can be know about an irq. The parallel arrays make the code harder to maintain and make it difficult to remove the static limits on the number of the number of irqs. This patch pushes irq_data and irq_vector into a irq_cfg array and updates the code to use it. Signed-off-by:

NR_IRQ_VECTORS is currently a compatiblity define set to NR_IRQs. This patch updates the users of NR_IRQ_VECTORS to use NR_IRQs instead so that NR_IRQ_VECTORS can be removed. There is still shared code with arch/i386 that uses NR_IRQ_VECTORS so we can't remove the #define just yet :( Signed-off-by:

If we have an irq that comes from multiple io_apic pins the FINAL action (which is io_apic_sync or nothing) needs to be called for every entry or else if the two pins come from different io_apics we may not wait until after the action happens on the io_apic. Signed-off-by:

For some reason the code has been picking TARGET_CPUS when asked to set the affinity to an empty set of cpus. That is just silly it's extra work. Instead if there are no cpus to set the affinity to we should just give up immediately. That is simpler and a little more intuitive. Signed-off-by:

Currently we have two routines that do practically the same thing setup_IO_APIC_irq and io_apic_set_pci_routing. This patch makes setup_IO_APIC_irq the common factor of these two previous routines. For setup_IO_APIC_irq all that was needed was to pass the trigger and polarity to make the code a proper subset of io_apic_set_pci_routing. Hopefully consolidating these two routines will improve maintenance there were several differences that simply appear to be one routine or the other getting it wrong. Signed-off-by:

This patch replaces all instances of "set_native_irq_info(irq, mask)" with "irq_desc[irq].affinity = mask". The latter form is clearer uses fewer abstractions, and makes access to this field uniform accross different architectures. Signed-off-by:

By precomputing old_mask I remove an extra if statement, remove an indentation level and make the code slightly easier to read. Signed-off-by:

This reverts commit 2ff2d3d7. Uwe Bugla reports that he cannot mount a floppy drive any more, and Jiri Slaby bisected it down to this commit. Benjamin LaHaise also points out that this is a big hot-path, and that interrupt delivery while idle is very common and should not go through all these expensive gyrations. Fix up conflicts in arch/i386/kernel/apic.c and arch/i386/kernel/irq.c due to other unrelated irq changes.

This reverts commit d2ed1635. As Thomas Gleixner reports: "e1000 is not working anymore. ifup fails permanentely. ADDRCONF(NETDEV_UP): eth0: link is not ready nothing else" The broken commit was identified with "git bisect". Auke Kok says: "I think we need to drop this now. The report that says that this *fixes* something might have been on regular interrupts only. I currently suspect that it breaks all MSI interrupts, which would make sense if I look a the code. Very bad indeed." Cc: Jesse Brandeburg <jesse.brandeburg@intel.com> Acked-by:

Commit 00c4cc67 Oliver Endriss changed the budget-ci driver to use interrupt mode for i2c transfers. This also meant that a new bunch of IR bytes that were previously lost are now received, which allowed me to better understand how the MSP430 chip works. Unfortunately it also means that the current driver gets some assumptions wrong and might generate double keypresses for one IR command. The attached patch fixes this by throwing away the repeat bytes and by associating the correct command and device bytes. Signed-off-by:

Arjan van de Ven <arjan@infradead.org> reported an illegal re-usage of the fileoperations struct if more than one dvb device (e.g. frontend) is present. This patch fixes this issue. It allocates a new fileoperations struct each time a device is registered and copies the default template fileops. Signed-off-by:

The work item function is dvb_usb_read_remote_control(): INIT_WORK(&d->rc_query_work, dvb_usb_read_remote_control, d); and the last piece of work it does is: schedule_delayed_work(&d->rc_query_work,msecs_to_jiffies(d->props.rc_interval)); Hence you need to call "cancel_rearming_delayed_work()" and not "cancel_delayed_work()", correct? I certainly haven't seen this oops reoccur since I applied this patch. Signed-off-by:Andrew Morton <akpm@linux-foundation.org> Signed-off-by:

gl861: (MSI Megasky) - hack for enable ZL10353 / QT1010 I2C gate - use new QT1010 module instead of old code au6610: (Sigmatek DVB-110) - hack for enable ZL10353 / QT1010 I2C gate - use new QT1010 module instead of old code Tested successfully with au6610 and gl861 devices against fi-Yllas frequencies. Now it locks perfectly with both devices. There is a "hack" to enable probable i2c gate in zl10535 demodulator. QT1010 doesn't respond to any i2c messages before we write 0x1a to demodulator register 0x62. In my understanding this should be fixed to demodulator code. Signed-off-by:

This patch adds driver for Sigmatek DVB-110 USB DVB-T stick. Stick has based on hardware of Qtuantek QT1010 tuner, Zarlink ZL10353 (Intel CE 6353) demodulator and Alcor Micro AU6610 DVB-T USB controller. HW is rather similar as used in MSI Megasky GL861. Currently, the driver works only in USB 2.0. In my understanding USB 1.1 is also supported by hw but I cannot test it due to lack of USB 1.1 port. Device supports only isochronous mode transfers. There is also eeprom in usb controller(at least in address range 0x80 - 0xbf) for storing data, eg. firmware. Anyway, firmware loading is not used / required by the device. There seems to be at least one unknown I2C device in address 0xa0, probably remote control or GPIO. Windows drivers reads registers from 0x00 to 0x07 from this unknown address. Driver is based on gl861 module. Tuner has a lot of problems to lock with megasky qt1010 module with this hardware with some broadcasting standards. Signed-off-by:
