2008-12-13cpumask: convert struct clock_event_device to cpumask pointers.Rusty Russell
Impact: change calling convention of existing clock_event APIs struct clock_event_timer's cpumask field gets changed to take pointer, as does the ->broadcast function. Another single-patch change. For safety, we BUG_ON() in clockevents_register_device() if it's not set. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: Ingo Molnar <mingo@elte.hu>

2007-07-21clockevents: fix resume logicThomas Gleixner
We need to make sure, that the clockevent devices are resumed, before the tick is resumed. The current resume logic does not guarantee this. Add CLOCK_EVT_MODE_RESUME and call the set mode functions of the clock event devices before resuming the tick / oneshot functionality. Fixup the existing users.

2006-11-03[ARM] 3918/1: ixp4xx irq-chip reworkKevin Hilman
This is a rework of the ixp4xx irq_chip implementation. The use of two irq_chip structures and potentially switching between them is a violation of the intended use of the IRQ framework. The current implementation does not work with current in-kernel spinlock debugging or lockdep due to lock recursion problems caused by calling set_irq_chip/handler from within the chip's set_irq_type(). This patch goes back to using one irq_chip structure and handling the differences between edge/level, normal/GPIO interrupts inside the ack/mask/unmask routines themselves.

2006-04-20[ARM] 3480/1: ixp4xx: fix irq2gpio array typeLennert Buytenhek
Patch from Lennert Buytenhek The irq2gpio array was recently converted from an array of ints to an array of chars (by patch 3368/1.) However, this array contains elements that are -1, and on ARM, the char type is unsigned by default, so this patch broke the GPIO check in ixp4xx_set_irq_type. Change the 'char' to be a 'signed char' to fix this.

2006-01-05[ARM] 3226/1: IXP4xx runtime expansion bus window size configurationDeepak Saxena
Patch from Deepak Saxena The expansion bus on the IXP46x NPU can be configured for either 32MiB or 16MiB windows and changing the configuration causes the base address for each chip select for each region to change. Because of this, we cannot hardcode the physical base as we currently do. This patch checks the expansion bus configuration registers at runtime to determine the appropriate window size. Note that this requires that the bootloader already configured the device sizes appropriately, but I feel that is valid assumption to make as the bootloader must configure and access the flash window, the output display (LCD, LEDs, etc) window, and other expansion bus devices.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
