[PATCH] ppc64: Move systemcfg out of head.S
The "systemcfg" data structure in the ppc64 kernel is something that used
to be defined to be at a hard-coded page number in the kernel image. This
is not necessary (at least not any more) and is a possible problem with
future developements. This patch removes that constraint, which also
simplifies various bits of assembly in head.S that were dealing with it.
This is the first step of a deeper cleanup of systemcfg definition of usage
(and ultimately removal in it's current incarnation).
