This is a note to let you know that I have just added a patch titled KVM: x86: preserve the high 32-bits of the PAT register to the linux-3.11.y-queue branch of the 3.11.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.11.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From a8b6fd631269532e953dac7e0f006b9f74fd5224 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini <pbonzini@redhat.com> Date: Thu, 19 Jun 2014 11:40:18 +0200 Subject: KVM: x86: preserve the high 32-bits of the PAT register commit 7cb060a91c0efc5ff94f83c6df3ed705e143cdb9 upstream. KVM does not really do much with the PAT, so this went unnoticed for a long time. It is exposed however if you try to do rdmsr on the PAT register.
