glibc/sysdeps/unix/sysv/linux/m68k
History
Joseph Myers e5a5315e2d Use direct socket syscalls for new kernels on i386, m68k, microblaze, sh. 
Now that we have __ASSUME_* macros for direct socket syscalls to use
them instead of socketcall when they can be assumed to be available on
socketcall architectures, this patch defines those macros when
appropriate for i386, m68k, microblaze and sh (for 4.3, 4.3, all
supported kernels and 2.6.37, respectively; the only use of socketcall
support on microblaze is it allows accept4 and sendmmsg to be
supported on a wider range of kernel versions).

David, it seems that 32-bit SPARC is the only architecture supported
by glibc that still lacks these direct syscalls.  It would be good to
get them added to the SPARC kernel so we can eventually eliminate
socketcall support in glibc (and thereby just use entries in
sysdeps/unix/syscalls.list for most of these functions) when we can
assume new-enough kernels.

Tested for i386 (testsuite, and that installed shared libraries are
unchanged by this patch - not using a new enough kernel, so this
doesn't actually test much, but the i386 and m68k code is essentially
the same as that already in use for s390).
