| * dm table: drop reference at unbindMikulas Patocka2009-01-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Move one dm_table_put() so that the last reference in the thread gets dropped in __unbind(). This is required for a following patch, dm-table-rework-reference-counting.patch, which will change the logic in such a way that table destructor is called only at specific points in the code.

Use the reset button to power the board back up; the power supply LED will be on, but the MSP430 waits to re-activate the regulators. - On probe() this: * Announces firmware revision * Turns off the banked LEDs * Exports the resources noted above * Hooks the power-off support * Muxes tvp5146 -or- imager for video input Unless the new tvp514x driver (tracked for mainline) is configured, this assumes that some custom imager driver handles video-in. This completely ignores the registers reporting the output voltages on the various power supplies. Someone could add a hwmon interface if that seems useful.

Both object and source code shrink. As part of this, some devices now have more IRQ resources: battery charger, keypad, ADC, and USB transceiver.

The hardware functions largely autonomously, with minimal software control required to initiate fast charging. Support for configuration of the USB supply is not yet implemented. This means that the hardware will remain in the mode configured at startup, by default limiting the current drawn from USB to 100mA.

With this interface subsystems that need a non-failing stop_machine environment can create the stop_machine machine threads before actually calling stop_machine. When the threads aren't needed anymore they can be killed with stop_machine_destroy again. When stop_machine gets called and the threads aren't present they will be created and destroyed automatically. This restores the old behaviour of stop_machine. This patch also converts cpu hotplug to the new interface since it is special: cpu_down calls __stop_machine instead of stop_machine. However the kstop threads will only be created when stop_machine gets called. Changing the code so that the threads would be created automatically on __stop_machine is currently not possible: when __stop_machine gets called we hold cpu_add_remove_lock, which is the same lock that create_rt_workqueue would take. So the workqueue needs to be created before the cpu hotplug code locks cpu_add_remove_lock.

With this patch we now instead add individual PLT stub entries directly in front of the code sections where the stubs are actually called. This reduces the distance between the PCREL location and the stub entry so that the relocations can be fulfilled. While calculating the final layout of the kernel module in memory, the kernel module loader calls arch_mod_section_prepend() to request the to be reserved amount of memory in front of each individual section.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's no point in including the linux/swiotlb.h header twice in lib/swiotlb.c - this patch gets rid of the unneeded include. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Ingo Molnar <mingo@elte.hu>
| * | | intel-iommu: fix build error with INTR_REMAP=y and DMAR=nIngo Molnar2009-01-041-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dmar.o can be built in the CONFIG_INTR_REMAP=y case but iommu_calculate_agaw() is only available if VT-d is built as well. So create an inline version of iommu_calculate_agaw() for the !CONFIG_DMAR case. The iommu->agaw value wont be used in this case, but the code is cleaner (has less #ifdefs) if we have it around unconditionally. Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new debugfs entry dumps all rsb and lkb structures, and includes a lot more information than has been available before.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use ktime instead of jiffies for timestamping lkb's. Also stamp the time on every lkb whenever it's added to a resource queue, instead of just stamping locks subject to timeouts. This will allow us to use timestamps more widely for debugging all locks.
