From 76306f4272e036e600254a98bc291df50cedd949 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Fri, 14 Feb 2014 16:30:52 +0000 Subject: [PATCH] MIPS: introduce cpu_coherent_mask Add a mask of CPUs which are currently known to be operating coherently. This is setup initially to be all present CPUs, but in a subsequent patch CPUs in a MIPS Coherent Processing System will be cleared in this mask as they enter non-coherent idle states. This will be used in order to determine when a CPU within a CPS system may need to be powered back up, but may also be used in future to optimise away wakeups for cache operations or TLB invalidations.
