Subject: [PATCH] x86: update cpu feature RDRND to RDRAND
Date: Tue, 24 May 2011 16:29:26 -0700 [thread overview]
Message-ID: <20110524232926.GA27728@outflux.net> (raw)
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".)
