Introduce little-endian bit operations by renaming native ext2 bit
operations. The ext2 bit operations are kept as wrapper macros using
little-endian bit operations to maintain bisectability until the
conversions are finished.

This introduces CONFIG_GENERIC_FIND_BIT_LE to tell whether to use generic
implementation of find_*_bit_le() in lib/find_next_bit.c or not.
For now we select CONFIG_GENERIC_FIND_BIT_LE for all architectures which
enable CONFIG_GENERIC_FIND_NEXT_BIT.
But m68knommu wants to define own faster find_next_zero_bit_le() and
continues using generic find_next_{,zero_}bit().
(CONFIG_GENERIC_FIND_NEXT_BIT and !CONFIG_GENERIC_FIND_BIT_LE)

This makes the little-endian bitops take any pointer types by changing the
prototypes and adding casts in the preprocessor macros.
That would seem to at least make all the filesystem code happier, and they
can continue to do just something like
#define ext2_set_bit __test_and_set_bit_le
(or whatever the exact sequence ends up being).

Introduce Kconfig option allowing architectures where sysdev
operations used during system suspend, resume and shutdown have been
completely replaced with struct sycore_ops operations to avoid
building sysdev code that will never be used.
Make callbacks in struct sys_device and struct sysdev_driver depend
on ARCH_NO_SYSDEV_OPS to allows us to verify if all of the references
have been actually removed from the code the given architecture
depends on.
Make x86 select ARCH_NO_SYSDEV_OPS.

Some subsystems in the x86 tree need to carry out suspend/resume and
shutdown operations with one CPU on-line and interrupts disabled and
they define sysdev classes and sysdevs or sysdev drivers for this
purpose. This leads to unnecessarily complicated code and excessive
memory usage, so switch them to using struct syscore_ops objects for
this purpose instead.
Generally, there are three categories of subsystems that use
sysdevs for implementing PM operations: (1) subsystems whose
suspend/resume callbacks ignore their arguments entirely (the
majority), (2) subsystems whose suspend/resume callbacks use their
struct sys_device argument, but don't really need to do that,
because they can be implemented differently in an arguably simpler
way (io_apic.c), and (3) subsystems whose suspend/resume callbacks
use their struct sys_device argument, but the value of that argument
is always the same and could be ignored (microcode_core.c). In all
of these cases the subsystems in question may be readily converted to
using struct syscore_ops objects for power management and shutdown.

GCC 4.6 explicitly represents the MDR register. It may be accessed
via the "z" constraint. Perhaps more importantly, it tracks when
the MDR register is clobbered and uses the RETF instruction if the
incoming value is still valid.
Thus it is important to (at least) clobber the MDR register in
relevant inline assembly fragments, lest RETF be used incorrectly.
The only instances I could find are here. There are reads of the
MDR register in kernel/gdb-stub.c, but that's harmless. Although,
frankly, __builtin_return_address(0) might be a better thing in
those cases. Certainly MDR isn't going to contain anything else
that might be useful...

This enables sharing of cs5535-mfd cells via the new mfd_shared_* API.
Hooks for enable/disble of resources are added, with refcounting of
resources being automatically handled so that cs5535_mfd_res_enable/disable
are only called when necessary.
Clients of cs5535-mfd (in this case, olpc-xo1.c) are also modified to

olpc-xo1-{pms,acpi}, and resource enabling/disabling is replaced

Note that mfd-core no longer makes a copy of platform_data, but the
mc13xxx-core driver creates the pdata structures on the stack. In
order to get around that, the various ARM mach types that set the
pdata have been changed to hold the variable in static (global) memory.
Also note that __initdata references in aforementioned pdata structs
have been dropped.
