[Xen-devel] [PATCH v2 00/11] nested vmx: bug fixes and feature enabling

[Dongxiao Xu <dongxiao.xu@xxxxxxxxx>]

This series of patches contain some bug fixes and feature enabling for
nested vmx, please help to review and pull.

For the following patches, it doesn't have influence about Xen on Xen 
functionality.
No special need to backport to 4.2.x (My own opinion).

Changes from v1 to v2:
 - Use literal name instead of hard numbers to expose default 1 settings in VMX 
related MSRs.
 - For TRUE VMX MSRs, we use the same value as normal VMX MSRs.
 - Fix a coding style issue.

Thanks,
Dongxiao
