Sam Ravnborg a439fe51a1 sparc, sparc64: use arch/sparc/include
The majority of this patch was created by the following script:

***
ASM=arch/sparc/include/asm
mkdir -p $ASM
git mv include/asm-sparc64/ftrace.h $ASM
git rm include/asm-sparc64/*
git mv include/asm-sparc/* $ASM
sed -ie 's/asm-sparc64/asm/g' $ASM/*
sed -ie 's/asm-sparc/asm/g' $ASM/*
***

The rest was an update of the top-level Makefile to use sparc
for header files when sparc64 is being build.
And a small fixlet to pick up the correct unistd.h from
sparc64 code.

* 3) As the result of store merge completion, writeback, or copyout will
* generate a disrupting ECC_error trap.
* 4) As the result of such errors on instruction vector fetch can generate any
* of the 3 trap types.

* The AFSR bits associated with these traps are EMU, EDU, WDU, CPU, IVU, UE,
