* | ARM: add a kuser_cmpxchg64 user space helper | Nicolas Pitre | 2011-06-28 | 1 | -0/+64 |
| | | | | | | | | | | Some user space applications are designed around the ability to perform atomic operations on 64 bit values. Since this is natively possible only with ARMv6k and above, let's provide a new kuser helper to perform the operation with kernel supervision on pre ARMv6k hardware.

* | ARM: kuser: move interface documentation out of the source code | Nicolas Pitre | 2011-06-20 | 1 | -0/+203 |
Digging into some assembly file in order to get information about the kuser helpers is not that convivial. Let's move that information to a better formatted file in Documentation/arm/ and improve on it a bit. Thanks to Dave Martin <dave.martin@linaro.org> for the initial cleanup and clarifications.
