[PATCH v3 0/5] SGX NUMA support plus vepc reset

[Yang Zhong <yang.zhong@intel.com>]

The basic SGX patches were merged into Qemu release, the left NUMA
function for SGX should be enabled. The patch1 implemented the SGX NUMA
ACPI to enable NUMA in the SGX guest. Since Libvirt need detailed host
SGX EPC sections info to decide how to allocate EPC sections for SGX NUMA
guest, the SGXEPCSection list is introduced to show detailed sections info
in the monitor or HMP interface.

This version also plus the vEPC reset support because the related kernel
patches were merged into tip tree master branch, please ref below link:

or the tip tree master branch.

Thanks!
