The following patch generalizes PPC44x_PIN_SIZE by changing it to PPC_PIN_SIZE, which can be defined by any sub-arch to automatically adjust VMALLOC_START. Define PPC_PIN_SIZE on 8xx, avoiding potential conflicts with the pinned space. Signed-off-by: Marcelo Tosatti <marcelo.tosatti@cyclades.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
