[SRU][T][PATCH 0/1] CVE-2017-7518 - Incorrect debug exception emulation

 Andy Lutomirski discovered that the KVM implementation in the Linux kernel
 was vulnerable to a debug exception error when single-stepping through a
 syscall. A local attacker in a non-Linux guest vm could possibly use this
 to gain administrative privileges in the guest vm.

This is a cherry-picked patch from the 3.16 linux-stable tree.
