We should follow suit for sanity's sake. (See Intel SDM Volume 2, Table 3-20 "Feature Information Returned in the ECX Register".) [ hpa: we can only do this at this time because there are currently no CPUs with this feature on the market, hence this is pre-hardware enabling. However, Cc:'ing stable so that stable can present a consistent ABI. ] Signed-off-by: Kees Cook Link: http://lkml.kernel.org/r/20110524232926.GA27728@outflux.net Signed-off-by: H.
