- Introduce MSG_NBIO so that we can turn non blocking i/o on a per call basis
- Use MSG_NBIO to fix the XXX: multi-threaded issues on the fifo sockets.
- Don't set SO_CANTRCVMORE, if we were interrupted (perhaps do it for all
errors?).
will not re-order accesses. Some versions of GCC (such as one in NetBSD
5.x) definitely do re-order reads from these fields if they're not
marked volatile.
an element of the SRCS list. This should fix a problem in which build
products were created in the source tree.
Also add a comment about where COMPAT_50 is defined.
As long as we hold the vnode interlock there is no chance for this vnode
to gain new references.
Fixes false alarms observed by Thor Lancelot Simon and reported on tech-kern.

Currently the MAP_NOSYSCALLS is only implemented for x86 but other
architectures are easy to adapt; see the sys/arch/x86/x86/syscall.c patch.
Port maintainers are encouraged to add them for their processor ports too.
When this feature is not yet implemented for an architecture the
MAP_NOSYSCALLS is simply ignored with virtually no cpu cost..
calls from the mapped region. This can be used for emulation perposed or for
extra security in the case of generated code.
Its implemented by adding mapping-attributes to each uvm_map_entry. These can
then be queried when needed.

Initialize abridged tag word properly. x87 spec says FNINIT says tag word
contains FFFFh (all stack locations empty) which would make abridged tag
word 00h. From the Intel 64 and IA-32 Architectures Software Developer's
Manual:
"The FXSAVE instruction saves an abridged version of the x87 FPU tag word
in the FTW field (unlike the FSAVE instruction, which saves the complete
tag word). The tag information is saved in physical register order (R0
through R7), rather than in top-of- stack (TOS) order. With the FXSAVE
instruction, however, only a single bit (1 for valid or 0 for empty) is
saved for each tag."

ioctl commands.
Tested with "rndctl -ls" using an old 32-bit version of rndctl(8)
(built for NetBSD-5.99.56/i386) and a new 64-bit kernel
(NetBSD-5.99.59/amd64).
KAME_IPSEC, and make IPSEC define it so that existing kernel
config files work as before
Now the default can be easily be changed to FAST_IPSEC just by
setting the IPSEC alias to FAST_IPSEC.
