From 846e1913f5ccf3fb822a7aa166e5a840c8bdc61b Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Sat, 12 Aug 2017 19:49:31 -0700 Subject: MIPS: CPS: Use change_*, set_* & clear_* where appropriate Make use of the new change_*, set_* & clear_* accessor functions for CPS (CM, CPC & GIC) registers where doing so makes the code easier to read or shortens it without adversely affecting readability.
