[PATCH] powerpc/security: Fix link stack flush instruction

2020-10-07 Thread Nicholas Piggin
The inline execution path for the hardware assisted branch flush instruction failed to set CTR to the correct value before bcctr, causing a crash when the feature is enabled. Fixes: 4d24e21cc694 ("powerpc/security: Allow for processors that flush the link stack using the special bcctr") Signed-of
