The following series of patches improves the zImage header on ppc64.
Similar code is used in openSuSE since a while and works well, on 32bit
and 64bit systems.
Two patches touch generic code, they are required to simplify the copying
of lib/zlib_inflate. Since the bootheader is 32bit and include/asm points
to 64bit headers, the source files cant be used as is.
I have tested the resulting zImage on a 44p 270, with stock yaboot 1.3.13.
