David S. Miller 9076d0e7e0 sparc: Access kernel TSB using physical addressing when possible. 
On sun4v this is basically required since we point the hypervisor and
the TSB walking hardware at these tables using physical addressing
too.

David S. Miller 293666b7a1 sparc64: Stop using memory barriers for atomics and locks. 
The kernel always executes in the TSO memory model now,
so none of this stuff is necessary any more.

With helpful feedback from Nick Piggin.

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.
