- how sysctl hw.machine_arch should be handled

Right now it return the MACHINE_ARCH the executable was built for via an ELF note.

I'd expect sysctl hw.something to report information about the hardware that's in use, or perhaps the hardware that the kernel was built for. It seems weird to report information about how the currently running executable was built.

Perhaps we need different sysctl nodes to report the kernel's idea of MACHINE_ARCH and the userland executable's idea of MACHINE_ARCH.

[lots of information]

Please could you document this somewhere. Some possible places that come to mind are sys/arch/README, sys/arch/*arm*/???, distrib/notes/*arm*/install.
