This is the v7 of syscall user dispatch. This version is a bit different from v6 on the following points, after the modifications requested on that submission.

Is this supposed to work with existing (Linux) libcs, or do you bring your own low-level run-time libraries?

Hi Florian,

The main use case is to intercept Windows system calls of an application running over Wine. While Wine is using an unmodified glibc to execute its own native Linux syscalls, the Windows libraries might be directly issuing syscalls that we need to capture. So there is a mix. While this mechanism is compatible with existing libc, we might have other libraries executing a syscall instruction directly.
