x86, cpufeature: Update CPU feature RDRND to RDRAND
The Intel manual changed the name of the CPUID bit to match the instruction name. 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 <kees.cook@canonical.com> Link: http://lkml.kernel.org/r/20110524232926.GA27728@outflux.net Signed-off-by: H.
