Tim Chen 488ca7d72d x86/cpufeatures: Enable cpuid for Intel SHA extensions ... Add Intel CPUID for Intel Secure Hash Algorithm Extensions. This feature provides new instructions for accelerated computation of SHA-1 and SHA-256. This allows the feature to be shown in the /proc/cpuinfo for cpus that support it. Refer to SHA extension programming guide in chapter 8.2 of the Intel Architecture Instruction Set Extensions Programming reference for definition of this feature's cpuid: CPUID.(EAX=07H, ECX=0):EBX.SHA [bit 29] = 1 https://software.intel.com/sites/default/files/managed/07/b7/319433-023.pdf Originally-by: Chandramouli Narayanan <mouli_7982@yahoo.com> Signed-off-by: Tim Chen <tim.c.chen@linux.intel.com> Cc: Borislav Petkov <bp@suse.de> Cc: Dave Hansen <dave.hansen@intel.com> Cc: Herbert Xu <herbert@gondor.apana.org.au> Link: http://lkml.kernel.org/r/1440194206.3940.6.camel@schen9-mobl2 Signed-off-by: Thomas Gleixner <tglx@linutronix.de>		2015-08-22 11:17:31 +02:00
