[PATCH 2.6.21-rc3-mm2 4/4] sys_futex64 : allows 64bit futexes

2007-03-13 Thread Pierre . Peiffer
This last patch is an adaptation of the sys_futex64 syscall provided in -rt patch (originally written by Ingo). It allows the use of 64bit futex. I have re-worked most of the code to avoid the duplication of the code. It does not provide the functionality for all architectures (only for x64 for
