this change works again for me.

svn commit: r250159 - in head: include lib/libc/sys sys/compat/freebsd32 sys/kern
Author: jilles
Date: Wed May 1 22:42:42 2013
New Revision: 250159
URL: http://svnweb.freebsd.org/changeset/base/250159
Log:
Add pipe2() system call.
The pipe2() function is similar to pipe() but allows setting FD_CLOEXEC and
O_NONBLOCK (on both sides) as part of the function.
If p points to two writable ints, pipe2(p, 0) is equivalent to pipe(p).
If the pointer is not valid, behaviour differs: pipe2() writes into the
array from the kernel like socketpair() does, while pipe() writes into the
array from an architecture-specific assembler wrapper.

svn commit: r250154 - in head: lib/libc/sys lib/libthr lib/libthr/thread sys/compat/freebsd32 sys/kern sys/sys
Author: jilles
Date: Wed May 1 20:10:21 2013
New Revision: 250154
URL: http://svnweb.freebsd.org/changeset/base/250154
Log:
Add accept4() system call.
The accept4() function, compared to accept(), allows setting the new file
descriptor atomically close-on-exec and explicitly controlling the
non-blocking status on the new socket. (Note that the latter point means
that accept() is not equivalent to any form of accept4().)
The linuxulator's accept4 implementation leaves a race window where the new
file descriptor is not close-on-exec because it calls sys_accept(). This
implementation leaves no such race window (by using falloc() flags). The
linuxulator could be fixed and simplified by using the new code.
Like accept(), accept4() is async-signal-safe, a cancellation point and
permitted in capability mode.

Log:
Partially saved extended state must be handled always, i.e. for both
fpu-owned context, and for pcb-saved one. More, the XSAVE could do
partial save, same as XSAVEOPT, so qualifier for the handler should be
use_xsave and not use_xsaveopt.
Since xsave_area_desc is now needed regardless of the XSAVEOPT use,
remove the write-only use_xsaveopt variable.

Author: kib Date: Wed May 1 20:03:50 2013 New Revision: 250152 URL: http://svnweb.freebsd.org/changeset/base/250152 Log: The check to ensure that xstate_bv always has XFEATURE_ENABLED_X87 and XFEATURE_ENABLED_SSE bits set is not needed. CPU correctly handles any bitmask which is subset of the enabled bits in %XCR0. More, CPU instructions XSAVE and XSAVEOPT could write the mask without e.g. XFEATURE_ENABLED_SSE, after the VZEROALL.
