Subject: [PATCH v3 2/2] Use direct socket syscalls for new kernels on sparc
Authentication-results: sourceware.org; auth=none
References: <1457113849-16532-1-git-send-email-aurelien at aurel32 dot net>

All direct socket syscalls have been added in kernel version 4.4 for
SPARC32.

The 3 missing direct socket syscalls bind, listen and setsockopt have
been added in kernel version 4.4 for SPARC64. All others were already
present for SPARC64 in kernel versions 3.2 or earlier.
