  Two more bug fixes from the gift that keeps on giving.  Both of these were
found by inspection, and both are lightly tested.  I'm pretty confident
that patch 01 fixes a real bug, somewhat less so about patch 02, though
given the other issues I debugged I don't see anything that prevents the
DS buffers from exploding.

Sean Christopherson (2):
  x86/mm: Recompute physical address for every page of per-CPU CEA
    mapping
  x86/mm: Populate KASAN shadow for per-CPU DS buffers in CPU entry area
