[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.

[PATCH v2 0/4] XEN: fix vmx exception mistake
Changes from v1:
- Define new struct hvm_trap to represent information of trap, include
instruction length.
- Renames hvm_inject_exception to hvm_inject_trap. Then define a couple of
wrappers around that function for existing callers, so that their parameter
lists actually *shrink*.
