move asm/unaligned.h to linux/unaligned.h 

asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

Of course this is a bad idea to rely on the alignment trap to perform

unaligned memory access in general.  If those access are predictable, you

are better to use the macros provided by include/asm/unaligned.h.  The

alignment trap can fixup misaligned access for the exception cases, but at

a high performance cost.  It better be rare.

===========================



The easiest way to avoid unaligned access is to use the get_unaligned() and

put_unaligned() macros provided by the <asm/unaligned.h> header file.

Going back to an earlier example of code that potentially causes unaligned
