  kvm: x86: Add AMD's EX_CFG to the list of ignored MSRs (2018-12-18 22:15:44 +0100)

----------------------------------------------------------------
* One nasty use-after-free bugfix, from this merge window however
* A less nasty use-after-free that can only zero some words at
the beginning of the page, and hence is not really exploitable
* A NULL pointer dereference
* A dummy implementation of an AMD chicken bit MSR that Windows uses
for some unknown reason
