More than the bottom two bits are now defined, and the MSR policy work has
shown that using non-architectural representations turns out to be problematic
for more than just asm code. As the architectural representation is the

Both Xen and the toolstack have need of the same logic when it comes to
manipulation and checking of the CPUID and MSR values offered to guests. To
that end, libx86 is being introduced to allow Xen and the toolstack to share a
single implementation, rather than duplicating
This series introduces libx86, a small shared library between the hypervisor
and libxc, and hypercalls to get full CPUID/MSR policies. Future work will
implement XEN_DOMCTL_set_cpumsr_policy, after the auditing and comparison

In the meantime, the data marshalling logic is in a su

xen/arch/x86/hvm
Hi all,
This patch series addresses the ideea of saving data from a single vcpu
instance.
First it starts by adding *save_one functions, then it introduces a handler for
the
new save_one* funcs and makes use of it in the hvm_save and hvm_save_one funcs.
The final 2 patches are used for clean up.
