			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. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
