[PATCH] iSeries build with newer assemblers and compilers

Paulus suggested that we put xLparMap in its own .c file so that we can
generate a .s file to be included into head.S.  This doesn't get around
the problem of having it at a fixed address, but it makes it more
palatable.

It would be good if this could be included in 2.6.13 as it solves our
build problems with various versions of binutils and gcc.  In
particular, it allows us to build an iSeries kernel on Debian unstable
using their biarch compiler.

This has been built and booted on iSeries and built for pSeries and g5.
