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

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..

Subject: sh: syscall 300 should be __NR_fstatat64.

syscall number 300 fails while testing with latest LTP
(ltp-full-20061121.tgz) on sh.

sys_fstatat64 is called on syscall 300 (see arch/sh/kernel/syscalls.S),
and __ARCH_WANT_STAT64 is defined in include/asm-sh/unistd.h, so
following patch seems correct.

There were a few more things that needed fixing up, namely THREAD_SIZE
and the TLB miss handler where certain PTRS_PER_PGD == PTRS_PER_PTE
assumptions were being made.

Subject: sh: Lazy dcache writeback optimizations.

This converts the lazy dcache handling to the model described in
Documentation/cachetlb.txt and drops the ptep_get_and_clear() hacks
used for the aliasing dcaches on SH-4 and SH7705 in 32kB mode. As a
bonus, this slightly cuts down on the cache flushing frequency.

With that and the PTEA handling out of the way, the update_mmu_cache()
implementations can be consolidated, and we no longer have to worry
about which configuration the cache is in for the SH7705 case.

And finally, explicitly disable the lazy writeback on SMP (SH-4A).

Subject: sh: SH-DMAC compile fixes

This patch does the following:
- remove the make_ipr_irq stuff from dma-sh.c and replace it
  with a simple channel<->irq mapping table.
- add DMTEx_IRQ constants for sh4 cpus
- fix sh7751 DMAE irq number

The SH7780 uses the same IRQs for DMA as other SH4 types, so
I put the constants on top of the dma.h file.

Other CPU types need to #define their own DMTEx_IRQ contants
in their appropriate header.

From 9c57548f17806ffd8e4dc4f7973ce78bbfbc2079 Mon Sep 17 00:00:00 2001
From: Paul Mundt <lethal@linux-sh.org>
Date: Thu, 15 Feb 2007 18:20:52 +0900
Subject: sh: rts7751r2d board updates.

This tidies up some of the rts7751r2d mess and gets it booting
again. Update the defconfig, too.
