[PATCH 0/2] linux-user: fixes for sched_ syscalls

[Tonis Tiigi]

This patchset improves support for sched_* syscalls under user emulation. The 
first commit adds support for sched_g/setattr that was previously not 
implemented. There is no equivalent for these syscalls in libc, so I needed to 
redefine the struct from kernel. It can't be included directly because of 
conflict with libc sched headers.

The second commit fixes sched_g/setscheduler and sched_g/setparam, when QEMU is 
built with musl. Musl does not implement these due to conflict between what 
these functions should do in syscalls and libc

 . I've changed it to call syscall directly what should always be the expected 
behavior for the user.
