• 40fb79c8a   ARM: add a kuser_cmpxchg64 user space helper ... Browse Code »

  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.

• 37b830464   ARM: kuser: move interface documentation out of the source code ... Browse Code »

  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 for the initial cleanup and
  clarifications.
