SIBYTE_CFE got killed in commit 05f94eebd5 ("MIPS: Sibyte: Remove
standalone kernel support"). This means that since v2.6.31 there is no
Kconfig symbol SIBYTE_CFE. The select statement for that symbol is a
nop. Drop it.

These comments mention CONFIG options that do not exist: not as a symbol
in a Kconfig file (without the CONFIG_ prefix) and neither as a symbol
(with that prefix) in the code.
There's one reference to XSCALE_PMU_TIMER as a negative dependency.
But XSCALE_PMU_TIMER is never defined (CONFIG_XSCALE_PMU_TIMER is
also unused in the code). It shows up with type "unknown" if you search
for it in menuconfig. Apparently a negative dependency on an unknown
symbol is always true. That negative dependency can be removed too.

These Kconfig entries have been commented out ever since commit f6557331
("[...] Re-organize Kconfig code for 4xx in arch/powerpc"). There's no
indication why they're commented out. It looks like they're just "old,
unused [...] config options" that were not removed, as other entries
were in that commit, but only commented out. They might as well be
removed now.

After adding PM QoS constraints for the I2C controller in the A4R
domain, that domain can be allowed to be turned off and on by runtime
PM, so remove the "always on" governor from it.
However, the A4R domain has to be "on" when suspend_device_irqs() and
resume_device_irqs() are executed during system suspend and resume,
respectively, so that those functions don't crash while accessing the
INTCS. For this reason, add a PM notifier to the SH7372 PM code and
make it restore power to A4R before system suspend and remove power
from all unused PM domains after system resume.

SH7372 uses two independent mechanisms for ensuring that power
domains will never be turned off: the stay_on flag and the "always
on" domain governor. Moreover, the "always on" governor is only taken
into accout by runtime PM code paths, while the stay_on flag affects
all attempts to turn the given domain off. Thus setting the stay_on
flag causes the "always on" governor to be unnecessary, which is
quite confusing.
However, the stay_on flag is currently only set for two domains: A3SP
and A4S. Moreover, it only is set for the A3SP domain if
console_suspend_enabled is set, so stay_on won't be necessary for
that domain any more if console_suspend_enabled is checked directly
in its .suspend() routine. [This requires domain .suspend() to
return a result, but that is a minor modification.] Analogously,
stay_on won't be necessary for the A4S domain if it's .suspend()
routine always returns an error code.

Since the SH7372's INTCS in included into syscore suspend/resume,
which causes the chip to be accessed when PM domains have been
turned off during system suspend, the A4R domain containing the
INTCS has to stay on during system sleep, which is suboptimal
from the power consumption point of view.
For this reason, add a new INTC flag, skip_syscore_suspend, to mark
the INTCS for intc_suspend() and intc_resume(), so that they don't
touch it. This allows the A4R domain to be turned off during
system suspend and the INTCS state is resrored during system
resume by the A4R's "power on" code.

The sh7372 contains a power domain named A4S which in turn
contains power domains for both I/O Devices and CPU cores.
At this point only System wide Suspend-to-RAM is supported,
but the the hardware can also support CPUIdle. With more
efforts in the future CPUIdle can work with bot A4S and A3SM.
Tested on the sh7372 Mackerel board.

The S3C64xx SoCs contain a set of gateable power domains which can be
enabled and disabled at runtime in order to save power. Use the generic
power domain code to implement support for these in software, enabling
runtime control of most domains:
- ETM (not supported in mainline).
- Domain G: 3D acceleration (no mainline support).
- Domain V: MFC (no mainline support).
- Domain I: JPEG and camera interface (no mainline support).
- Domain P: 2D acceleration, TV encoder and scaler (no mainline support)
- Domain S: Security (no mainline support).
- Domain F: LCD (driver already uses runtime PM), post processing and
rotation (no mainline support).
The IROM domain is marked as always enabled as we should arrange for it
to be enabled when we suspend which will need a bit more work.
Due to all the conditional device registration that the platform does
wrap s3c_pm_init() with s3c64xx_pm_init() which actually puts the device
into the power domain after the machines have registered, looking for
platform data to tell if the device was registered. Since currently only
Cragganmore actually sets up PM that is the only machine updated.

The current generic PM domains code requires that the same .stop(),
.start() and .active_wakeup() device callback routines be used for
all devices in the given domain, which is inflexible and may not
cover some specific use cases. For this reason, make it possible to
use device specific .start()/.stop() and .active_wakeup() callback
routines by adding corresponding callback pointers to struct
generic_pm_domain_data. Add a new helper routine,
pm_genpd_register_callbacks(), that can be used to populate
the new per-device callback pointers.
Modify the shmobile's power domains code to allow drivers to add
their own code to be run during the device stop and start operations
with the help of the new callback pointers.

Since the PM core is now going to execute driver callbacks directly
if the corresponding subsystem callbacks are not present,
forward-only subsystem callbacks (i.e. such that only execute the
corresponding driver callbacks) are not necessary any more. Thus
it is possible to remove generic_subsys_pm_ops, because the only
callback in there that is not forward-only, .runtime_idle, is not
really used by the only user of generic_subsys_pm_ops, which is
vio_bus_type.
However, the generic callback routines themselves cannot be removed
from generic_ops.c, because they are used individually by a number
of subsystems.

Move invalidate_bdev, block_sync_page into fs/block_dev.c. Export
kill_bdev as well, so brd doesn't have to open code it. Reduce
buffer_head.h requirement accordingly.
Removed a rather large comment from invalidate_bdev, as it looked a bit
obsolete to bother moving. The small comment replacing it says enough.

Seeing that just about every destructor got that INIT_LIST_HEAD() copied into
it, there is no point whatsoever keeping this INIT_LIST_HEAD in inode_init_once();
the cost of taking it into inode_init_always() will be negligible for pipes
and sockets and negative for everything else. Not to mention the removal of
boilerplate code from ->destroy_inode() instances...
