Maintainers for: alpha, ia64 and m68k, please have a look, your arch code is funny. The header magic is a bit odd, but similar to the KERNEL_DS one, CPP waits with expanding these macros until the INIT_THREAD_INFO macro itself is expanded, which is in arch/*/kernel/init_task.c where we've already included sched.h so we're good.

| | * | sh: cpuidle for SuperH Mobile using hwblkMagnus Damm2009-07-051-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds cpuidle support for SuperH Mobile. The sleep mode selected by cpuidle is compared with the mode selected by the hwblk sleep code and the best allowed mode is entered. At this point "Sleep mode" and "Sleep mode + SF" are supported. This code can easily be extended to support "Software suspend mode", but the assembly code must first be updated to avoid loosing interrupts. Also, update the code to only copy the assembly snippet into internal memory once at bootup. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch contains the sh7722 specific hwblk implementation. Hwblk ids are added to the processor specific header file, module stop bits and areas are kept track of as hwblks, clocks are converted to make use of the shared hwblk code. Code to determine allowed sleep modes is also added. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

A each processor model should provide a list of hwblks and describe which module stop bit that is associated with each hwblck and how the hwblks are grouped together into areas. The shared code keeps track of the usage count for each hwblk and the areas. Fallback implementations for processor specific code are also kept as weak symbols. The clock framework, the runtime pm code and cpuidle will all tie into this hwblk implementation. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The irqsoff tracer uses the atomic_* functions internally, but the implementations of those functions in arch/sh/include/asm/atomic-irq.h disable irqs to achieve atomicity. A continuous loop ensues where we disable interrupts, trace the interrupt disabling, call atomic_* functions, disable interrupts, trace the interrupt disabling, etc.. The simplest solution to all this is to just convert uses of local_irq_save()/local_irq_restore() the raw_* equivalents because the raw_* equivalents don't call trace_hardirqs_on()/trace_hardirqs_off().

Move the KM_FENCE_ macro additions into asm-generic/kmap_types.h, controlled by __WITH_KM_FENCE from each arch's kmap_types.h file. Would be nice to be able to add custom KM_types per arch, but I don't yet see a nice, clean way to do that. Built on x86_64, i386, mips, sparc, alpha(tonyb), powerpc(tonyb), and 68k(tonyb). Note: avr32 should be able to remove KM_PTE2 (since it's not used) and then just use the generic kmap_types.h file. Get avr32 maintainer approval.
