[POWERPC] Remove bogus comment about page_is_ram
arch/powerpc/mm/mem.c states that page_is_ram is called by the code that implements /dev/mem, which isn't true. Remove the comment. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Cc: Paul Mackerras <paulus@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
