From 8a5a5d1530d55e367ef29c80946d0274717617bb Mon Sep 17 00:00:00 2001 From: Mathias Krause Date: Sun, 7 Sep 2014 20:30:29 +0200 Subject: [PATCH] x86-64, ptdump: Mark espfix area only if existent We should classify the espfix area as such only if we actually have enabled the corresponding option. Otherwise the page table dump might look confusing. Signed-off-by: Mathias Krause Link: http://lkml.kernel.org/r/1410114629-24523-1-git-send-email-minipli@googlemail.com Cc: Arjan van de Ven Cc: H.
