* sh: Fix IPR-IRQ's for IRQ-chip change breakage.Jamie Lenehan2006-10-311-2/+8
| | | | | | | | | | | | | | | The conversion from IPR-IRQ to IRQ-chip resulted in the ipr data being allocated in a local variable in make_ipr_irq - breaking anything using IPR interrupts. This changes all of the callers of make_ipr_irq to allocate a static structure containing the IPR data which is then passed to make_ipr_irq. This removes the need for make_ipr_irq to allocate any additional space for the IPR information. Signed-off-by: Jamie Lenehan <lenehan@twibble.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Convert INTC2 to IRQ table registration.Paul Mundt2006-10-203-13/+1
| | | | | | | | | | | | | Currently the INTC2 code contains a fixed IRQ table that it iterates through to set the handler type, we move this in to the CPU subtype setup code instead and allow for submitting the table that way. This drops the ST40 tables, as nothing has been happening with those processors, while converting the only existing users to use the new table directly (SH7760 and SH7780).

* sh: Add some missing board headers.Paul Mundt2006-10-196-0/+420
| | | | | | | Some of these were dropped in the header directory rework, add the few missing ones back in. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fix exception_handling_table alignment.Paul Mundt2006-10-191-0/+7
| | | | | | | | | | | 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.

* sh: Cleanup board header directories.Paul Mundt2006-10-197-434/+0
| | | | | | | | Now with the ide.h mess sorted out, most of these boards don't need their own directory. Move the headers out, and update the driver paths. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Remove board-specific ide.h headers.Paul Mundt2006-10-197-72/+0
| | | | | | | | | | The driver that these were using never made it in to drivers/ide, so kill off the rest of the cruft. These will have to be reworked for board-specific platform devices through libata when they're added back through the setup code. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Proper show_stack/show_trace() implementation.Paul Mundt2006-10-191-0/+2
| | | | | | | | | | This splits out some of the previous show_stack() implementation which was mostly doing the show_trace() work without actually dumping any of the stack contents. This now gets split in to two sections, where we do the fetching of the stack pointer and subsequent stack dumping in show_stack(), while moving the call trace in to show_trace().

| | | | | | | | | | | | | | | | | | | | | | | | | | At the moment we wrap GENERIC_TIME around our existing timer API. As boards start providing their own clocksources, they're able to select GENERIC_TIME accordingly and optimize out most of the timer API. Once the current timers have been reworked as proper clocksource drivers, the rest of the place holders for the timer API can go away and we can flip on GENERIC_TIME unconditionally.

* [PATCH] Directed yield: cpu_relax variants for spinlocks and rw-locksMartin Schwidefsky2006-10-011-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | On systems running with virtual cpus there is optimization potential in regard to spinlocks and rw-locks. If the virtual cpu that has taken a lock is known to a cpu that wants to acquire the same lock it is beneficial to yield the timeslice of the virtual cpu in favour of the cpu that has the lock (directed yield). With CONFIG_PREEMPT="n" this can be implemented by the architecture without common code changes. Powerpc already does this. With CONFIG_PREEMPT="y" the lock loops are coded with _raw_spin_trylock, _raw_read_trylock and _raw_write_trylock in kernel/spinlock.c. If the lock could not be taken cpu_relax is called. A directed yield is not possible because cpu_relax doesn't know anything about the lock. To be able to yield the lock in favour of the current lock holder variants of cpu_relax for spinlocks and rw-locks are needed. The new _raw_spin_relax, _raw_read_relax and _raw_write_relax primitives differ from cpu_relax insofar that they have an argument: a pointer to the lock structure.
