[PATCH] ppc64: systemcfg is now a pointer
The following patch fixes 2 issues:
1) use PLATFORM_LPAR bit to test if running in LPAR mode
2) systemcfg pointer is assigned from static data in
arch/ppc64/kernel/pacaData.c. The file arch/ppc64/kernel/head.S
now refers to is using the GOT binding to the pointer and hence
must deref it.
