We have had a number of cases where <asm/cpufeature.h> (and its predecessors) have diverged substantially from the names list in /proc/cpuinfo. This patch generates the latter from the former. It retains the option for explicitly overriding the strings, but by making that require a separate action it should at least be less likely to happen. It would be good to do a future pass and rename strings that are gratuituously different in the kernel (/proc/cpuinfo is a userspace interface and must remain constant.) Signed-off-by: H.
