++//
++// * ARMv5 didn't support SMP, there is no memory barrier instruction at
++// all on this architecture, or when targeting its machine code.
++//
++// * Some ARMv6 CPUs support SMP. A full memory barrier can be produced by
++// writing a random value to a very specific coprocessor register.
++//
++// * On ARMv7, the "dmb" instruction is used to perform a full memory
++// barrier (though writing to the co-processor will still work).
++// However, on single core devices (e.g. Nexus One, or Nexus S),
++// this instruction will take up to 200 ns, which is huge, even though
++// it's completely un-needed on these devices.
++//
++// * There is no easy way to determine at runtime if the device is
++// single or multi-core. However, the kernel provides a useful helper
++// function at a fixed memory address (0xffff0fa0), which will always
++// perform a memory barrier in the most efficient way. I.e. on single
++// core devices, this is an empty function that exits immediately.
++// On multi-core devices, it implements a full memory barrier.
++//
++// * This source could be compiled to ARMv5 machine code that runs on a
++// multi-core ARMv6 or ARMv7 device. In this case, memory barriers
++// are needed for correct execution. Always call the kernel helper, even
++// when targeting ARMv5TE.
