-+// Memory barriers on ARM are funky, but the kernel is here to help:
-+//
-+// * 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.
