Support for generic input output for MX1 family.
The implementation prevents allocation of one pin
by two users, but does not store pointer to the user
description permanently, because this solution
would have bigger memory overhead.
The simple way to integrate code with per BSP
pins setup and allocation is required else all GPIO
registration checking is useless. The function
imx_gpio_setup_multiple_pins() can be used for this
purpose in future.

The SiS966 has one additional PCI-ID 1180.
If the chipset is using this PCI-ID, the primary channel is connected to the
first PATA-port. The secondary channel is connected to SATA-ports in IDE
emulation mode. The legacy IO-ports are used.
The including of the PCI-ID into pata_sis is not sufficient, because the legacy
driver in drivers/ide is initialized before pata_sis.

The idle loop goes to sleep using the WAIT instruction if !need_resched().
This has is suffering from from a race condition that if if just after
need_resched has returned 0 an interrupt might set TIF_NEED_RESCHED but
we've just completed the test so go to sleep anyway. This would be
trivial to fix by just disabling interrupts during that sequence as in:
local_irq_disable();
if (!need_resched())
__asm__("wait");
local_irq_enable();
but the processor architecture leaves it undefined if a processor calling
WAIT with interrupts disabled will ever restart its pipeline and indeed
some processors have made use of the freedom provided by the architecture
definition. This has been resolved and the Config7.WII bit indicates that
the use of WAIT is safe on 24K, 24KE and 34K cores. It also is safe on
74K starting revision 2.1.0 so enable the use of WAIT with interrupts
disabled for 74K based on a c0_prid of at least that.

Uninline virq_to_hw and export it so modules can use it. The alternative
would be to export the irq_map array instead, but it's an infrequently
called function, and keeping the array unexported seems considerably
cleaner.
This is needed so that the pasemi_mac driver can be compiled as a module.

Commit 52ade9b3b9 changed the suspend code
ordering to execute pm_ops->prepare() after the device model per-device
.suspend() calls in order to fix some ACPI-related issues. Unfortunately, it
broke the at91 platform which assumed that pm_ops->prepare() would be called
before suspending devices.
at91 used pm_ops->prepare() to get notified of the target system sleep state,
so that it could use this information while suspending devices. However, with
the current suspend code ordering pm_ops->prepare() is called too late for
this purpose. Thus, at91 needs an additional method in 'struct pm_ops' that
will be used for notifying the platform of the target system sleep state.
Moreover, in the future such a method will also be needed by ACPI.
This patch adds the .set_target() method to 'struct pm_ops' and makes the
suspend code call it, if implemented, before executing the device model
per-device .suspend() calls. It also modifies the at91 code to use
pm_ops->set_target() instead of pm_ops->prepare().

Many laptops have rf-kill physical switches that are not keys, but slider
or rocker switches. Often (like in all ThinkPads with a radio kill slider
switch), they have both a slider/rocker switch and a hot key.
Trying to kludge a real switch to act like a key is not a very smart thing
to do if you can help it, and it gets specially bad when you are going to
have both in the same machine. So, we do the right thing and add an input
EV_SW event for radio kill switches.
The EV_SW SW_RADIO event is defined with positive logic, i.e. when the
switch is active, the radios are to be enabled. When the switch is
inactive, the radios are to be disabled.

Not all the world is an i386. Many architectures need 64-bit arguments to be
aligned in suitable pairs of registers, and the original
sys_sync_file_range(int, loff_t, loff_t, int) was therefore wasting an
argument register for padding after the first integer. Since we don't
normally have more than 6 arguments for system calls, that left no room for
the final argument on some architectures.
Fix this by introducing sys_sync_file_range2(int, int, loff_t, loff_t) which
all fits nicely. In fact, ARM already had that, but called it
sys_arm_sync_file_range. Move it to fs/sync.c and rename it, then implement
the needed compatibility routine. And stop the missing syscall check from
bitching about the absence of sys_sync_file_range() if we've implemented
sys_sync_file_range2() instead.
Tested on PPC32 and with 32-bit and 64-bit userspace on PPC64.

The infamous abnormal status message triggers on not so abnormal cases
including empty port and even when it's being triggered on actual
errors the info it provides is redundant and out of context - higher
level functions will print the info in better safe later anyway.
Also, by being triggered all the time, it leads people to think that
the abnormality is somehow related to all ATA and system problems
they're experiencing and gives owners of healthy systems unfounded
doubts about the integrity of the universe. Make it a DPRINTK and
