asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

Initialize the instance of struct fb_ops with fbdev initializer
macros for framebuffers in I/O address space. Set the read/write,
draw and mmap callbacks to the correct implementation and avoid
implicit defaults. Also select the necessary I/O helpers in Kconfig.
Fbdev drivers sometimes rely on the callbacks being NULL for a
default implementation to be invoked; hence requiring the I/O
helpers to be built in any case. Setting all callbacks in all
drivers explicitly will allow to make the I/O helpers optional.
This benefits systems that do not use these functions.
No functional changes.

ioremap_uc() is only meaningful on old x86-32 systems with the PAT
extension, and on ia64 with its slightly unconventional ioremap()
behavior, everywhere else this is the same as ioremap() anyway.
Change the only driver that still references ioremap_uc() to only do so
on x86-32/ia64 in order to allow removing that interface at some
point in the future for the other architectures.
On some architectures, ioremap_uc() just returns NULL, changing
the driver to call ioremap() means that they now have a chance
of working correctly.

Set struct fb_ops and with FB_DEFAULT_IOMEM_OPS, fbdev's initializer

Select the correct modules with Kconfig's FB_IOMEM_HELPERS token.

Support the kernel's nomodeset parameter for all PCI-based fbdev
drivers that use aperture helpers to remove other, hardware-agnostic
graphics drivers.
The parameter is a simple way of using the firmware-provided scanout
buffer if the hardware's native driver is broken. The same effect
could be achieved with per-driver options, but the importance of the
graphics output for many users makes a single, unified approach
worthwhile.
With nomodeset specified, the fbdev driver module will not load. This
unifies behavior with similar DRM drivers. In DRM helpers, modules
first check the nomodeset parameter before registering the PCI
driver. As fbdev has no such module helpers, we have to modify each
driver individually.
The name 'nomodeset' is slightly misleading, but has been chosen for
historical reasons. Several drivers implemented it before it became a
general option for DRM. So keeping the existing name was preferred over
introducing a new one.

Fix W=1 warnings about variables assigned but never used.
- One variable is only used when CONFIG_FB_ATY_GENERIC_LCD is defined
Fix so variable is only defined with CONFIG_FB_ATY_GENERIC_LCD
- Several variables was only assigned by a call to aty_ld_le32().
Drop the variables but keep the call to aty_ld_le32() as it may
have unexpected side-effects.
v2:
- Updated subject (Lee)

Fix warning about variable that is asssigned a value but never used.
The variable was indeed never used so delete it.
Keep the call to radeon_probe_i2c_connector() as it may have
side-effects. It is unlikely but I could not verify that is was safe to
drop the call.

The changes made in below mentioned commit removed CONFIG_PM containers
from drivers/video/fbdev/aty/atyfb_base.c but not from
drivers/video/fbdev/aty/atyfb.h for respective callbacks.
This resulted in error for implicit declaration for those callbacks.

Drivers using legacy PCI power management .suspend()/.resume() callbacks
have to manage PCI states and device's PM states themselves. They also
need to take care of standard configuration registers.
Switch to generic power management framework using a "struct dev_pm_ops"
variable to take the unnecessary load from the driver.
This also avoids the need for the driver to directly call most of the PCI
helper functions and device power state control functions, as through
the generic framework PCI Core takes care of the necessary operations,
and drivers are required to do only device-specific jobs.

Fixes commit 42ddb453a0cd ("radeon: Conditionally compile PM code")
Before the above mentioned patch, codes between the line number 547 and
2803 were already inside "#ifdef CONFIG_PM" container. Thus, addition of
"#if defined(CONFIG_PM)" was not required in the patch. It also affected
the "#ifdef CONFIG_PPC_OF" container (line 1943-2510).
From the current snapshot of radeon_pm.c, remove:
1434 | #if defined(CONFIG_PM)
and,
2213 | #endif
This removes the redundant CONFIG_PM directive as well as fixes the
CONFIG_PPC (earlier CONFIG_PPC_OF) container.

Drivers should do only device-specific jobs. But in general, drivers using
legacy PCI PM framework for .suspend()/.resume() have to manage many PCI
PM-related tasks themselves which can be done by PCI Core itself. This
brings extra load on the driver and it directly calls PCI helper functions
to handle them.
Switch to the new generic framework by updating function signatures and
define a "struct dev_pm_ops" variable to bind PM callbacks. Also, remove
unnecessary calls to the PCI Helper functions along with the legacy
.suspend & .resume bindings.
Now,
- aty128_pci_suspend() had a "pm_message_t" type parameter as per legacy
PCI PM framework that got deprecated in generic.
- Rename the callback as aty128_pci_suspend_late() and preserve the
parameter.
- Define 3 new callbacks as:
* aty128_pci_suspend()
* aty128_pci_freeze()
* aty128_pci_hibernate()
which in turn call aty128_pci_suspend_late() by passing appropriate
value for "pm_message_t" type parameter.
- Bind the callbacks in "struct dev_pm_ops" type variable
"aty128_pci_pm_ops".
