Linux does not define __BYTE_ORDER in its endian header files which makes
some header files bend backwards to get at the current endian. Lets
#define __BYTE_ORDER in big_endian.h/litte_endian.h to make it easier for
header files that are used in user space too.
In userspace the convention is that
1. _both_ __LITTLE_ENDIAN and __BIG_ENDIAN are defined,
2. you have to test for e.g. __BYTE_ORDER == __BIG_ENDIAN.

asm-generic/atomic.h has been derived from the mn10300 implementation.
Remove the now duplicated mn10300 implementation by including the generic
version instead.
This adds cmpxchg_local() and cmpxchg64_local() for free to the
architecture, as they are implemented in asm-generic/atomic.h.

gdb-7 and emacs gud mode happy:
(*) The D command. Detach debugger.
(*) The H command. Handle setting the target thread by ignoring it.
(*) The qAttached command. Indicate we 'attached' to an existing process.
(*) The qC command. Indicate that the current thread ID is 0.
(*) The qOffsets command. Indicate that no relocation has been done.
(*) The qSymbol:: command. Indicate that we're not interested in looking up
any symbol addresses.
(*) The qSupported command. Indicate the maximum packet size and the fact
that reverse step and continue aren't supported.
(*) The vCont? command. Indicate that we don't support any of its variants.
Also make it possible to trace the commands and replies without tracing
the individual character I/O.

Add a little strncpy optimization which can easily cut boot time by 20%.
When the kernel is booting with initramfs, it builds up the filesystem
from a cpio archive by calling strncpy_from_user() via fs/namei.c's
do_getname() on every file in the archive (which can be lots) with a
length of PATH_MAX (1024). This causes the dest of the strncpy to be
padded with many NUL bytes.
This optimization mostly causes these NUL bytes to be padded with a call
to memset() which is already optimized for filling memory quickly, but
the hardware loop helps a little bit as well.
Boot time measured with 'loglevel=0' so UART speed doesn't get in the way.

The IADDR2DTEST() macro had some duplicated logic with bit 11 and some
incorrect comments, so scrub all of that.
In order to verify these aren't a problem (and won't be in the future),
extend the self tests to operate on as much L1 SRAM as possible.

Since 'extern inline' doesn't work correctly in the context of the Linux
kernel (too many overriding defines), move the string functions to normal
lib/ assembly files (like the existing mem funcs). This avoids the forced
inline all over the kernel and allows us to place them constantly in L1.
This also avoids some module failures when gcc inserts calls to string
functions but the kernel build system doesn't fully consult the library
archives.

While the CC pseudo register can be deduced from the ASTAT register, make
sure we set its value correctly instead of always stubbing it out as 0.
GDB itself looks at this pseudo register instead of ASTAT, so we have to
supply the right value.

NMIs are not safe to return from because many anomaly workarounds are
implemented by disabling interrupts. The NMI obviously violates this
assumption. Since the NMI watchdog never returns, we don't have to
worry about it clobbering RETN when it is being used as a scratch register
with the exception stack.

A few pseudo debug insns exist to make testing of simulators easier.
Since these don't actually exist in the hardware, we have to have the
exception handler take care of emulating these. This allows sim test
cases to be executed unmodified under Linux and thus simplify debugging
greatly.

.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver. This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.
This patch is a pretty mechanical change. The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial. This patch looks big and scary because it touches so
many files, but it should be pretty safe.
