[PATCH] x86, cpufeature: add feature bit for SDBG

2015-07-19 Thread Mathias Krause
Add a CPUID feature bit for the SDBG (Silicon Debug) CPU feature found on recent Intel systems starting with Haswell. Using the IA32_DEBUG_INTERFACE MSR (index C80H) one can at least detect if SDBG has been enabled by the firmware and if it has been used or not. Signed-off-by: Mathias Krause Cc:
