From a81dc9d9957354ee2ebc2e387cbc10cf457b9948 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Wed, 27 Jul 2016 13:39:42 +1000 Subject: [PATCH] powerpc/kernel: Convert mmu_has_feature() to returning bool The intention is that the result is only used as a boolean, so enforce that by changing the return type to bool.
