[PATCH][SVM] Fix 32bit Windows guest VMs save/restore
The attached patch fixes the save/restore issue seen with 32bit Windows
guest VMs. The root cause is that current Xen doesn''t intercept
SYSENTER-related MSRs for 32bit guest VMs. As a result, the
guest_sysenter_xxx fields contain incorrect values and shouldn''t be used
for save/restore. This patch checks the LMA bit of EFER register in the
save/restore code path.
Please apply it to both Xen-4.0 and Xen-unstable trees.
