each of the existing kernel configs. This gives a place to put config that applies to the entire arch. Add the ARM_NEW_PMAP option to std.armv6. This is working well in early testing and it's time for wide exposure, but it's still nice to be able to fall back to the old implementation for testing when a problem comes along. Eventually the option and the old implementation will go away. The opportunity now exists to move a whole lot of boilerplate from all the arm kernel config files into std.arm*, but that's a commit for another day.
