Paolo, Ok sure. Will change "int bit" to "u32 vector". I will send a new
patch to address this. This needs to be addressed in all these functions,
vmcb_set_intercept, vmcb_clr_intercept, vmcb_is_intercept,
set_exception_intercept, clr_exception_intercept, svm_set_intercept,
svm_clr_intercept, svm_is_intercept.
Also will add WARN_ON_ONCE(vector > 32); on set_exception_intercept,
clr_exception_intercept. Does that sound good?
