57a55077dd Blackfin arch: update defconfig file for all boards
- do not bother generating deprecated /sys files by default now since
   mdev does not need it
 - Don't built-in char sport driver and build it as a module in defconfig
 - disable CONFIG_DEVKMEM by default
 - enable spi flash driver on boards that have one
 - switch config to the NAND platfrom driver rather than the bfin async one
 - do not make BFIN_DMA_5XX optional since a large portion of our code relies
   on dma functions existing

ede6f5aea0 Fix up 64-bit byte swaps for most 32-bit architectures
The __SWAB_64_THRU_32__ case of a 64-bit byte swap was depending on the
no-longer-existant ___swab32() method (three underscores).  We got rid
of some of the worst indirection and complexity, and now it should just
use the 32-bit swab function that was defined right above it.

991c0e6d1a byteorder: only use linux/swab.h
The first step to make swab.h a regular header that will
include an asm/swab.h with arch overrides.

Avoid the gratuitous differences introduced in the new
linux/swab.h by naming the ___constant_swabXX bits and
__fswabXX bits exactly as found in the old implementation
in byteorder/swab[b].h

Use this new swab.h in byteorder/[big|little]_endian.h and
remove the two old swab headers.

Although the inclusion of asm/byteorder.h looks strange in
linux/swab.h, this will allow each arch to move the actual
arch overrides for the swab bits in an asm file and then
the includes can be cleaned up without requiring a flag day
for all arches at once.

Keep providing __fswabXX in case some userspace was using them
directly, but the revised __swabXX should be used instead in
any new code and will always do constant folding not dependent
on the optimization level, which means the __constant versions
can be phased out in-kernel.

Arches that use the old-style arch macros will lose their
optimized versions until they move to the new style, but at
least they will still compile.  Many arches have already moved
and the patches to move the remaining arches are trivial.
