Cover letter [MODERATED] [PATCH 0/1] SMTCTL 0

Here's an alternative proposal for SMT disabling.

I reimplemented my script as a C tool and put it into tools/*

# smtctl --enable
# smtctl --disable
# smtctl --print

Advantages:
- No kernel changes (although it would benefit from a minor one, see the commit)
- Much easier to use at runtime than opaque sysfs
- Encourages the right use model of only switching SMT state when it is actually needed and based on a conscious decision, not unnecessarily or globally.
