Subject: [PATCH 0/6] x86: infrastructure to enable FSGSBASE
Date:   Mon,  4 Jun 2018 12:24:23 -0700
Message-Id: <1528140269-26205-1-git-send-email-chang.seok.bae@intel.com>

Precedence: bulk

Given feedbacks from [1], it was asked to make first a few
patches ready as soon as possible. To make FSGSBASE facilitated,
some helper functions and refactoring work are incorporated.
Besides that, it includes Andy's fix for accurate FS/GS base read
and cleanup for the vDSO initialization.
