sh: Fix exception_handling_table alignment.

2006-10-19T07:30:32Z

With the recent change ripping out interrupt_table, explicit padding of the table was missing, causing bad things to happen when manually inserting handlers in to the table. This problem particularly showed up in relation to do_fpu_state_restore() which was inserted quite deeply in to the table and ended up scribbling over a slab object. Signed-off-by: Paul Mundt

sh: More cosmetic cleanups and trivial fixes.

2006-09-27T08:03:56Z

Nothing exciting here, just trivial fixes.. Signed-off-by: Paul Mundt

sh: APM/PM support.

2006-09-27T07:20:22Z

This adds some simple PM stubs and the basic APM interfaces, primarily for use by hp6xx, where the existing userland expects it. Signed-off-by: Andriy Skulysh Signed-off-by: Paul Mundt

sh: xchg()/__xchg() always_inline fixes for gcc4.

2006-09-27T07:05:56Z

Make __xchg() a macro, so that gcc 4.0 doesn't blow up thanks to always_inline.. Signed-off-by: Paul Mundt

sh: Cleanup and document register bank usage.

2006-09-27T07:01:12Z

Initial register bank cleanup. Make SR.RB configurable, and add some preliminary documentation on register bank usage within the kernel. Signed-off-by: Paul Mundt

sh: Add control register barriers.

2006-09-27T05:57:44Z

Currently when making changes to control registers, we typically need some time for changes to take effect (8 nops, generally). However, for sh4a we simply need to do an icbi.. This is a simple patch for implementing a general purpose ctrl_barrier() which functions as a control register write barrier. There's some additional documentation in the patch itself, but it's pretty self explanatory. There were also some places where we were not doing the barrier, which didn't seem to have any adverse effects on legacy parts, but certainly did on sh4a. It's safer to have the barrier in place for legacy parts as well in these cases, though this does make flush_tlb_all() more expensive (by an order of 8 nops). We can ifdef around the flush_tlb_all() case for now if it's clear that all legacy parts won't have a problem with this. Signed-off-by: Paul Mundt

sh: Support for SH-4A memory barriers.

2006-09-27T05:05:52Z

SH-4A supports 'synco' as a barrier, sprinkle it around the cache ops as necessary.. Signed-off-by: Paul Mundt

sh: Add a simple cmpxchg().

2006-09-27T02:28:20Z

We didn't have one of these before, a simple implementation borrowed from MIPS as well as the __HAVE_ARCH_CMPXCHG bits. Signed-off-by: Tom Rini Signed-off-by: Paul Mundt

[PATCH] remove set_wmb - arch removal

2006-07-15T04:56:14Z

set_wmb should not be used in the kernel because it just confuses the code more and has no benefit. Since it is not currently used in the kernel this patch removes it so that new code does not include it. All archs define set_wmb(var, value) to do { var = value; wmb(); } while(0) except ia64 and sparc which use a mb() instead. But this is still moot since it is not used anyway. Hasn't been tested on any archs but x86 and x86_64 (and only compiled tested) Signed-off-by: Steven Rostedt Signed-off-by: Linus Torvalds

[PATCH] sched: cleanup, remove task_t, convert to struct task_struct

2006-07-03T22:27:11Z

cleanup: remove task_t and convert all the uses to struct task_struct. I introduced it for the scheduler anno and it was a mistake. Conversion was mostly scripted, the result was reviewed and all secondary whitespace and style impact (if any) was fixed up by hand.
