I introduced this header some time ago for UBIFS support (for PowerPC).
As you may have noticed, it's a copy from the Linux version. And I
would like to keep it this way if possible. Looking at the Linux ARM
version, the basic difference seems to be the header
"include/asm-arm/unaligned.h" which includes this file. The Linux
version of "unaligned.h" does *not* include "access_ok.h" at all. It
includes "le_byteshift.h" and "be_byteshift.h" instead. And I would
really like to keep this in sync with Linux if possible.
So why not do it this way (totally untested):
