>Description:
	sys/arch/x86/x86/procfs_machdep.c have not maintained, so it's
	not a good way to check a CPU's feature with /proc/cpuinfo.

	An workaround is to use "cpuctl identify" command.
>How-To-Repeat:
	cat /proc/cpuinfo
>Fix:
	Sync with the latest spec.
	Almost the same code exists in src/usr.sbin/cpuctl/arch/i386.c
	but the output format is completely different.

 If we'd sync again with the userland stuff, can we also add the pretty printed
 attach messages back ;-)

 Alternatively: kill it completely, or make it just export some strange binary
 file(s)?

 - Decode NetBSD's ci_feat_val[0-5]. The output order of the bits is the same as
   linux. Before this commit, only ci_feat_val[0] was decoded.
 - Linux defined feature words and some others are not decoded yet.
 - procfs_getonecpufeatures() will be rewritten when all of linux entries are
   decoded.
