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. # # Reported-by: Larry Finger # Signed-off-by: Christophe Leroy # Fixes: cd08f109e262 ("powerpc/32s: Enable CONFIG_VMAP_STACK") # Tested-by: Larry Finger # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/7bce32ccbab3ba3e3e0f27da6961bf6313df97ed.1581663140.git.christophe.leroy@c-s.fr # <
