3 > sse3: Use the SSE3 instruction set (pni in cpuinfo)
4 > ssse3: Use the SSSE3 instruction set

6 I'd suggest a parenthetical on ssse3 as well, something like:
7
8 ssse3: Use the SSSE3 instruction set (NOT sse3, three s)

10 I know that confused me for awhile, and I tend to be reasonably literate
11 (as a user, anyway) on this sort of thing, so I'd not be surprised in the
12 least if a lot of sse3 only folks end up enabling it in error, as I did.
13 The explicit three-count pointer should help eliminate that sort of
14 confusion.
