[PATCH] x86/mm: fix invalid unlinking of nested p2m tables
...to a possible race condition where another allocation between
the two kinds of table being torn down can lead to a linked list
assertion with debug=y builds or memory corruption on debug=n ones.
Fix by swapping the order the two kinds of table are torn down in. While
at it, remove the condition in p2m_final_teardown, as it is already
checked identically in p2m_teardown_hostp2m itself.

[PATCH 00/11] Add virtual EPT support Xen.
From: Zhang Xiantao <xiantao.zhang@intel.com>
With virtual EPT support, L1 hyerpvisor can use EPT hardware
for L2 guest''s memory virtualization. In this way, L2 guest''s
performance can be improved sharply. According to our testing,
some benchmarks can show > 5x performance gain.
