LWP: Add LWP support for SVM guestsThis patch enables SVM to handle LWP related MSRs and CPUID. It intercepts guests read/write to LWP_CFG. It also save/restore LWP_CFG when guests touch this MSR. The LWP_CBADDR MSR is not intercepted because this MSR is handled by xsave/xrstor. Signed-off-by: Wei Huang <wei.huang2@xxxxxxx>
