#     powerpc/6xx: Fix power_save_ppc32_restore() with CONFIG_VMAP_STACK
#     
#     power_save_ppc32_restore() is called during exception entry, before
#     re-enabling the MMU. It substracts KERNELBASE from the address
#     of nap_save_msscr0 to access it.
#     
#     With CONFIG_VMAP_STACK enabled, data MMU translation has already been
#     re-enabled, so power_save_ppc32_restore() has to access
#     nap_save_msscr0 by its virtual address.
