Used the following script to copy the files:
cd include
set -e
SPARC64=`ls asm-sparc64`
for FILE in ${SPARC64}; do
	if [ -f asm-sparc/$FILE ]; then
		echo $FILE exist in asm-sparc
	else
		git mv asm-sparc64/$FILE asm-sparc/$FILE
		printf "#include <asm-sparc/$FILE>\n" > asm-sparc64/$FILE
		git add asm-sparc64/$FILE
	fi

We'll need this to handle NUMA properly on some systems.

Decrease the SECTION_SIZE_BITS --> MAX_PHYSADDR_BITS
range a little bit.

The cost of going to SPARSEMEM_STATIC becomes 8K of BSS space, and in
return we save a pointer dereferences on every page struct lookup.
Even better we hit the main kernel image for the base address which is
in a hugepage locked TLB entry.

This has been pending for a long time, and the fact
that we waste a ton of ram on some configurations
kind of pushed things over the edge.
