3447ef29a7 microblaze: Don't use access_ok for unaligned
it assumes we have an unaligned exception handler which

 (a) may not be true
 (b) costs a lot of performance
 Instead we'll use struct/union method for big endian accesses,
  and byte-shifting for little endian.

6e3d4e1d16 microblaze: Guard __HAVE_ARCH macros with __KERNEL__ in string.h
A polarity reversal in the __KERNEL__ guard prevents the __HAVE_ARCH
flags from being defined in kernel compilation.

I noticed that there's now an option for assembly-optimized versions of
memcpy and memmove. I believe this may be buggy; when I turn it on, all
my printk output gets smashed together, as if the newlines aren't getting
copied.

f2224ff07f microblaze: use generic dma-mapping-broken.h
Microblaze does not support the Linux DMA mapping API
at this point, so disable CONFIG_NO_DMA. This lets
us use the generic dma-mapping-broken.h implementation
instead of providing a different copy.

Any drivers that try to use DMA mapping now get
omitted from Kconfig or produce a link error, rather
than failing silently at run time.

732703af9c microblaze: clean up checksum.c
This changes the function prototypes in the checksum code
to have the usual prototypes, typically by turning int
arguments into __wsum.

Also change csum_partial_copy_from_user() to operate
on the right address space and export ip_fast_csum,
which is used in modular networking code.

The new version is now sparse-clean including endianess
checks.

0763ed2355 of: make of_(un)register_platform_driver common code
Some drivers using of_register_platform_driver() wrapper break on sparc
because the wrapper isn't in the header file.  This patch moves it from
Microblaze and PowerPC implementations and makes it common code.

Fixes this sparc64 allmodconfig build error (at least):

drivers/leds/leds-gpio.c: In function `gpio_led_init':
drivers/leds/leds-gpio.c:295: error: implicit declaration of function `of_register_platform_driver'
