URL: https://svnweb.freebsd.org/changeset/base/332859
Log:
Export powerpc CPU features for auxvec
FreeBSD exports the AT_HWCAP* auxvec items if provided by the ELF sysentvec
structure. Add the CPU features to be exported, so user space can more
easily check for them without using the hw.cpu_features and hw.cpu_features2
sysctls.
