From 9b2d1d8f61f598fb69a0c69f997bd8ca5190ef3f Mon Sep 17 00:00:00 2001 From: Felix Held Date: Thu, 22 Sep 2022 16:12:58 +0200 Subject: include/cpu/x86/mtrr: define NUM_FIXED_MTRRS once in mtrr.h Instead of defining NUM_FIXED_MTRRS in both cpu/x86/mp_init.h and cpu/x86/mtrr/mtrr.c in two different ways that will evaluate to the same value, define it once in include/cpu/x86/mtrr.h which is included in both C files.
