Instead of evaluating the cpu features for ELF_HWCAP every exec, calculate it once at boot time. Add AV_SPARC_* capability flag bits, compatible with what Solaris reports to applications. Report these capabilities once in the kernel log, and also via /proc/cpuinfo in a new "cpucaps" entry. If available, fetch the cpu features from the machine description 'hwcap-list' property of the 'cpu' node. Signed-off-by: David S. Miller <davem@davemloft.net> |
