Patches 2+3 are only about handling the legacy boot params that have a sysctl
counterpart.
In fact, the sysctl_aliases[] is (or could be) effectively the whitelist that Luis Chamberlain
was requesting in another thread. A whitelist makes good sense, for the reasons Luis listed.
As such, keeping it limited to items that we want, seems like the way to go, IMHO.
See my reply there once I send it :)
