[PATCH 0/7] powerpc: branch cache flush changes

2020-06-09 Thread Nicholas Piggin
This series allows the link stack to be flushed with the speical bcctr 2,0,0 flush instruction that also flushes the count cache if the processor supports it. Firmware does not support this at the moment, but I've tested it in simulator with a patched firmware to advertise support. Thanks, Nick
