[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.
