Subject: [PATCH 0/2] x86/xen/pvh: Clean up stack canary setup in PVH entry

Clean up the stack canary setup in the PVH entry. For a 64-bit kernel,
use fixed_percpu_data to set up GSBASE. For a 32-bit kernel, set up the
%fs register explicitly.

Hou Wenlong (2):
  x86/xen/pvh: Set up percpu for stack canary in 32-bit kernel entry
  x86/xen/pvh: Use fixed_percpu_data to set up GS base
