This ended up causing problems for older parts (particularly ones
using PTEA). Revert this for now, it can be added back in once it's
had some more testing.

This consolidates the various board heartbeat LED implementations,
used for strobing the load average across a LED bank. Those boards
not implementing a full bank can hook in via the LED class.
We leave the compat hook in the machvec for now until those non-banked
boards are able to migrate to the drivers/leds.

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.

Only SH-4 needs to set _PAGE_WT when using write-through caching,
don't attempt to set it on SH-3 where it ends up being a reserved

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).

The iVDR clock enable bit happens to actually reside in a rather
different place than what is documented, so fix it up accordingly.

default-enable the clock in the loader.

This allows the baud rate for earlyprintk for sh4 without the
standard BIOS to be set via the command line. This uses the same
format as i386 and x86_64, which is:
earlyprintk=serial,ttySC1,38400
The second parameter (ttySC1 above) is usually the console device
name or the io address of the serial port. I allow that to be
specified but ignore it in order to keep the format the same as
i386/x86_64.

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.

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..

This reverts some bogosity from the dynamic command-line
changes made on sparc32 and sparc64.
Drivers such as drivers/sbus/char/openprom.c reference
saved_command_line, and can be modular.
The boot_command_line is __initdata, yet the dynamic command-line
changes add modular exports of that symbol, obviously wrong.

Regarding RFC3775, MH payload proto field should be IPPROTO_NONE. Otherwise
it must be discarded (and the receiver should send ICMP error).
We assume filter should drop such piggyback everytime to disallow slipping

NF_CT_STAT_INC assumes rcu_read_lock in nf_hook_slow disables
preemption as well, making it legal to use __get_cpu_var without
disabling preemption manually. The assumption is not correct anymore
with preemptable RCU, additionally we need to protect against softirqs
when not holding nf_conntrack_lock.
Add NF_CT_STAT_INC_ATOMIC macro, which disables local softirqs,
and use where necessary.
