*	sh: Make the atomic functions safe for irqsoff tracing	Matt Fleming	2009-06-14	1	-12/+12
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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().

*	sh: Use the atomic_t "counter" member	Matt Fleming	2009-01-29	1	-8/+8
\| \| \| \| \| \| \| \| \| \| \| \|	Now that atomic_t is a generic opaque type for all architectures, it is unwise to use intimate knowledge of its internals when manipulating it. Instead of relying on the "counter" member being at offset 0 from the beginning of an atomic_t, explicitly reference the member. This guards us from any changes to the layout of the beginning of the atomic_t type. Signed-off-by: Matt Fleming <matt@console-pimps.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
*	sh: migrate to arch/sh/include/	Paul Mundt	2008-07-29	1	-0/+71
	This follows the sparc changes a439fe51a1f8eb087c22dd24d69cebae4a3addac. Most of the moving about was done with Sam's directions at: http://marc.info/?l=linux-sh&m=121724823706062&w=2 with subsequent hacking and fixups entirely my fault.
