[PATCH] S390: Call direct system calls for socket operations.

Subject: [PATCH] S390: Call direct system calls for socket operations.
Authentication-results: sourceware.org; auth=none

Hi,

this patch calls direct system calls for socket operations in the sameway as power does. The system calls were introduced in kernel commithttps://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=977108f89c989b1eeb5c8d938e1e71913391eb5f.

There are no direct recv, send, accept syscalls available on s390. Thus

recvfrom, sendto, accept4 are called instead of the socketcall. Seerecv.c, send.c, accept.c in sysdeps/unix/sysv/linux/s390 folder.

The socketcalls in syscalls.list for s390-64 are removed. They werenever used on s390x.


Bye Stefan
