powerpc/power8: Fix secondary CPUs hanging on boot for HV=0

2013-05-08T03:08:16Z

commit 8c2a381734fc9718f127f4aba958e8a7958d4028 upstream. In __restore_cpu_power8 we determine if we are HV and if not, we return before setting HV only resources. Unfortunately we forgot to restore the link register from r11 before returning. This will happen on boot and with secondary CPUs not coming online. This adds the missing link register restore.

powerpc: Move initial mfspr LPCR out of __init_LPCR

2012-11-15T04:08:05Z

We want to change what's initially set in the LPCR, so start by taking the move from LPCR out of the function and into the caller. Signed-off-by: Matt Evans Signed-off-by: Michael Neuling Signed-off-by: Benjamin Herrenschmidt
