Ingo Molnar 7124a9b682 x86/stackprotector/64: Only export __ref_stack_chk_guard on CONFIG_SMP 
[ Upstream commit 91d5451d97 ]

The __ref_stack_chk_guard symbol doesn't exist on UP:

  <stdin>:4:15: error: ‘__ref_stack_chk_guard’ undeclared here (not in a function)

Fix the #ifdef around the entry.S export.
