From d85f33342a0f57acfbe078cdd0c4f590d5608bb7 Mon Sep 17 00:00:00 2001 From: Juergen Gross Date: Mon, 3 Nov 2014 14:01:53 +0100 Subject: x86: Use new cache mode type in asm/pgtable.h Instead of directly using the cache mode bits in the pte switch to using the cache mode type. This requires changing some callers of is_new_memtype_allowed() to be changed as well.
