We can't currently use asm-ppc/page.h in vmlinux.lds.S, so until we have a merged page.h, define PAGE_SIZE and KERNELBASE locally. Also gets rid of some dynamic executable cruft that we had for 32-bit. With -Ttext=$(KERNELBASE) this didn't cause any problem, but when we changed to putting . = KERNELBASE in the vmlinux.lds.S this cruft caused the text to get linked at 0xa0 instead of 0xc0000000. Oops. Signed-off-by: Paul Mackerras <paulus@samba.org>
