ARM: clps711x: make all virtual addresses definition via one macro
This patch make all virtual addresses definition via one macro. This modification allows to avoid warning "BUG: mapping for 0x80000000 at 0xff000000 out of vmalloc space". Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
