Title:
  [SKL] starting xterm crashes the xserver

Status in linux package in Ubuntu:
  Incomplete
Status in linux source package in Vivid:
  Incomplete

Bug description:
  It was observed that starting certain apps (xterm, amdcccle) crash the
  xserver on Skylake. Rough bisect showed that 4.1-rc6 was ok while rc5
  wasn't, and git bisect found the fixing commit:

  commit 061cc3ab4c7b8ed235466134a00b9531766f6c1a
  Author: Ingo Molnar <mingo@xxxxxxxxxx>
  Date:   Wed May 20 11:45:30 2015 +0200

      x86/fpu: Disable XSAVES* support for now

  while it's also cc'd to stable@, it's needed in the vivid kernel now
  to make the (backport) kernel deadline for 14.04.3.
