From 905259e33d0ca0ee8e0d55783c3eef3402df81b7 Mon Sep 17 00:00:00 2001 From: Kevin Hao Date: Sat, 23 Jul 2016 14:42:39 +0530 Subject: [PATCH] powerpc: Remove mfvtb() This function is only used by get_vtb(). They are almost the same except the reading from the real register. Move the mfspr() to get_vtb() and kill the function mfvtb(). With this, we can eliminate the use of cpu_has_feature() in very core header file like reg.h. This is a preparation for the use of jump label for cpu_has_feature().
