sh: Make sure rte delay slots are nopped out on all parts.

2009-08-14T22:41:45+00:00

Future SH parts do not support any instruction but a nop in the rte delay
slot, so make the change for all offending parts. SH-5 is excluded from
this, and already has its own set of restrictions with regards to rte
delay slot handling.

sh: migrate to arch/sh/include/

2008-07-28T23:09:44+00:00

This follows the sparc changes a439fe51a1f8eb087c22dd24d69cebae4a3addac.

Most of the moving about was done with Sam's directions at:

with subsequent hacking and fixups entirely my fault.

sh: Fix up the address error exception handler for SH-2.

2008-03-13T10:43:07+00:00

Presently the SH-2/SH-2A address error exception dispatch copies off the
register state from the stack and skips over the first register, skewing
the rest. Fix up the math here so that the proper register state is
handed down to the exception handler itself.

sh: Fixup misaligned data for sh2 lockdep.

2007-06-11T06:33:44+00:00

lockdep/irqflags tracing on SH-2 ends up with a misaligned
branch, fix it.

sh: Fix bogus regs pointer in do_IRQ().

2007-03-14T04:03:35+00:00

SH-3 and SH-4 were trampling the register, and SH-2 wasn't even
setting it in the first place. This ended up with some rather
broken behaviour in the sysrq show_regs().

sh: Use a jump call table for debug trap handlers.

2007-02-13T01:54:43+00:00

This rips out most of the needlessly complicated sh_bios and kgdb
trap handling, and forces it all through a common fast dispatch path.
As more debug traps are inserted, it's important to keep them in sync
for all of the parts, not just SH-3/4.

As the SH-2 parts are unable to do traps in the >= 0x40 range, we
restrict the debug traps to the 0x30-0x3f range on all parts, and
also bump the kgdb breakpoint trap down in to this range (from 0xff
to 0x3c) so it's possible to use for nommu.

Optionally, this table can be padded out to catch spurious traps for
SH-3/4, but we don't do that yet..
