Subject: [ 14/89] ARM: virt: boot secondary CPUs through the right entry point

3.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Marc Zyngier <marc.zyngier@....com>

commit 6e484be1ccca3ea495db45900fd42aac8d49d754 upstream.

Secondary CPUs should use the __hyp_stub_install_secondary entry
point, so boot mode inconsistencies can be detected.
