[PATCH] powerpc: Move various ppc64 files with no ppc32 equivalent to powerpc
This patch moves a bunch of files from arch/ppc64 and include/asm-ppc64 which have no equivalents in ppc32 code into arch/powerpc and include/asm-powerpc. The file affected are: abs_addr.h compat.h lppaca.h paca.h tce.h cpu_setup_power4.S ioctl32.c firmware.c pacaData.c The only changes apart from the move and corresponding Makefile changes are: - #ifndef/#define in includes updated to _ASM_POWERPC_ form - trailing whitespace removed - comments giving full paths removed - pacaData.c renamed paca.c to remove studlyCaps - Misplaced { moved in lppaca.h Built and booted on POWER5 LPAR (ARCH=powerpc and ARCH=ppc64), built for 32-bit powermac (ARCH=powerpc).
