powerpc/476: Workaround for PLB6 hang
The 476FP core may hang if an instruction fetch happens during an msync following a tlbsync. This workaround makes sure that enough instruction cache lines are pre-fetched before executing the msync. (sync and msync are the same to the compiler.) Signed-off-by: Dave Kleikamp <shaggy@linux.vnet.ibm.com> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
