[Qemu-devel] [PATCH 00/14] target-i386: Implement MPX extension

[Richard Henderson]

I'm still in the process of testing this, as there's no code
written for it yet and hardware to compare against doesn't
start shipping until (probably) August.

But in the meantime there are a number of holes that I found
in XSAVE support that might affect KVM, and one question wrt
SMM support that affects MPX.  So I thought I'd get some 
feedback on this sooner than later.

This patch set depends on the addressing cleanup patchset that
I just posted.  It ought to depend on Pavel Dovgalyuk's exception
handling cleanup patchset, but I haven't included that in my tree.

Comments?
