+Subject: [PATCH] x86, cpu: Add CPU flags for F16C and RDRND
+
+commit 24da9c26f3050aee9314ec09930a24c80fe76352 upstream.
+
+Add support for the newly documented F16C (16-bit floating point
+conversions) and RDRND (RDRAND instruction) CPU feature flags.

+Subject: [PATCH] x86, cpufeature: Update CPU feature RDRND to RDRAND
+
+commit 7ccafc5f75c87853f3c49845d5a884f2376e03ce upstream.
+
+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. ]
