IRQ_LOCOMO_* are never used elsewhere, remove these definitions. As well
as the cascade of these IRQs. IRQ_LOCOMO_*_BASE changed to IRQ_LOCOMO_*.
IRQ_LOCOMO_LT and IRQ_LOCOMO_SPI are likely to be used in a same way as
IRQ_LOCOMO_KEY.
IRQ_LOCOMO_GPIO and the demultiplex handler should really be living
somewhere else.

It is not necessary and is over-complicated for IRQ_LOCOMO_KEY to
be a cascaded IRQ of IRQ_LOCOMO_KEY_BASE. Removed and introduced
locomokbd_{open,close} for masking/unmasking of the keyboard IRQ.

These IRQ definitions related to LOCOMO are never referenced anywhere,
thus could be safely removed.

Missing AC97 pin configurations are added where pxa_set_ac97_info() are

This is really pxa27x specific and should be kept in pxa27x.c. With this
newly introduced function, the original set_resetgpio_mode() is deprecated.

* Modification of Kconfig to add the Option
* 1 new file : buffalo-wxl-setup.c
This file is inspired from the db-78xx0-setup.c already present.
The following is done:
- Configure MPP Lines for the plateform (see my patch for MPP)
This is taken from the stock kernel provided by buffalotech (the vendor)
- GigaBit Ethernet
- Sata
- Uart are initiallized in a different way than on the dev board as we
have one core only.
- USB
The kernel has been running for some days now on my plateform.

This patch is composed of two new files :
- mpp.c which is mainly inspired by the same file as in mach-kirkwood
- mpp.h that is written from the documentation provided by Marvell
http://www.marvell.com/products/processors/embedded/discovery_innovation/HW_MV78100_OpenSource.pdf
Moreover, due to some implementation problem, I have
defined some MPPX_UNUSED that offer developers the possibility
to SET MPP to some unused value (such as for Buffalo WXL).
Note: This patch doesn't support MV78200 yet (only 78100 MPP lines have
been written)

The 'outer_cache' variable is needed by the outer_inv_range(),

We broke "acpi=ht" in 2.6.32 by disabling MADT parsing
for acpi=disabled. e5b8fc6ac158f65598f58dba2c0d52ba3b412f52
This also broke systems which invoked acpi=ht via DMI blacklist.
acpi=ht is a really ugly hack,
but restore it for those that still use it.

This follows the parisc change to ensure that tracehook_signal_handler()
is aware of when we are single-stepping in order to ptrace_notify()
appropriately. While this was implemented for 32-bit SH, sh64 neglected
to make use of TIF_SINGLESTEP when it was folded in with the 32-bit code,
resulting in ptrace_notify() never being called.
As sh64 uses all of the other abstractions already, this simply plugs in
the thread flag in the appropriate enable/disable paths and fixes up the
tracehook notification accordingly. With this in place, sh64 is brought
in line with what 32-bit is already doing.

Recent U-Boot commit 5ccd29c3679b3669b0bde5c501c1aa0f325a7acb caused
the "cpu-release-addr" device tree property to contain the physical RAM
location that secondary cores were spinning at. Previously, the
"cpu-release-addr" property contained a value referencing the boot page
translation address range of 0xfffffxxx, which then indirectly accessed
RAM.
The "cpu-release-addr" is currently ioremapped and the secondary cores
kicked. However, due to the recent change in "cpu-release-addr", it
sometimes points to a memory location in low memory that cannot be
ioremapped. For example on a P2020-based board with 512MB of RAM the
following error occurs on bootup:
<...>
mpic: requesting IPIs ...
__ioremap(): phys addr 0x1ffff000 is RAM lr c05df9a0

Oops: Kernel access of bad area, sig: 11 [#1]

This is because mpic_alloc() assigns wrong values to
mpic->isu_{size,shift,mask}, and things eventually break when
_mpic_irq_read() is trying to use them.
This patch fixes the issue by enabling MPIC_BROKEN_FRR_NIRQS quirk.

Mike Frysinger pointed out that calling tracehook_signal_handler with
stepping=0 missed testing the thread flags, resulting in not calling
ptrace_notify. Fix this by testing if we're single stepping or branch
stepping and setting the flag accordingly.
Tested, seems to work.

In its <asm/elf.h> ia64 defines SET_PERSONALITY in a way that unconditionally
sets the personality of the current process to PER_LINUX, losing any flag bits
from the upper 3 bytes of current->personality. This is wrong. Those bits are
intended to be inherited across exec (other code takes care of ensuring that
security sensitive bits like ADDR_NO_RANDOMIZE are not passed to unsuspecting
setuid/setgid applications).

As reported by Maxime Bizon, the commit "MIPS: PowerTV: Fix support for
timer interrupts with > 64 external IRQs" have broken the r4k timer
since it didn't initialize the cp0_compare_irq_shift variable used in
c0_compare_int_pending() on the architectures whose cpu_has_mips_r2 is
false.
This patch fixes it via initializing the cp0_compare_irq_shift as the
cp0_compare_irq used in the old c0_compare_int_pending().

This patch fixes the power LED on DNS-323 revision A1, and adds timer
support for (hopefully) both A1 and B1 revisions.
Power LED on revision A1 is active low and also requires GPIO 4 to be
low to work.
Tested on my DNS-323 revision A1.
I have set the default trigger to timer as that replicates the
behaviour of the original firmware, userspace can change the trigger
at the end of the boot process providing a useful indication that
booting has completed.
