table 'values' as IP addresses, use an explicit argument (-i).
This is a 'POLA' issue. This is a low risk change and should be MFC'd
to RELENG_6 and RELENG 7. it might be put as an errata item for 6.3.

optimization of about 10% for cos(x), sin(x) and tan(x) on
|x| < 2**19*pi/2. We didn't do this before because __ieee754__rem_pio2()
is too large and complicated for gcc-3.3 to inline very well. We don't
do this for float precision because it interferes with optimization
of the usual (?) case (|x| < 9pi/4) which is manually inlined for float
precision only.
This has some rough edges:
- some static data is duplicated unnecessarily. There isn't much after
the recent move of large tables to k_rem_pio2.c, and some static data
is duplicated to good affect (all the data static const, so that the
compiler can evaluate expressions like 2*pio2 at compile time and
generate even more static data for the constant for this).
- extern inline is used (for the same reason as in previous inlining of
k_cosf.c etc.), but C99 apparently doesn't allow extern inline
functions with static data, and gcc will eventually warn about this.
Convert to __FBSDID().
Indent __ieee754_rem_pio2()'s declaration consistently (its style was
made inconsistent with fdlibm a while ago, so complete this).
Fix __ieee754_rem_pio2()'s return type to match its prototype. Someone
changed too many ints to int32_t's when fixing the assumption that all
ints are int32_t's.
NFS root r/w.
The real solution would be to bring the whole nmount(2)
framework, including FS drivers and userland tools, into
a consistent state at last; but things should work in the
meantime, too.

more human readable by telling the human print routines to use
a smaller buffer to format the value.
This makes it so a value that was previously being printed
as 600000K will now print as 586M.
file system. In particular, stop overwriting mount point
flags in nfs_mountdiskless() because now they are set
elsewhere. (They were _initialized_ by that function in
the 4.4BSD days, when mount structures were not allocated
in a centralized manner -- see rev. 1.1 of this file.)
Fix nfs_mount(), which happened to depend on the loss of
MNT_ROOTFS when it came to update handling.
Also note that mountnfs() no longer handles updates. Now
they shouldn't reach this function, so printf a diagnostic
message if that happens due to a coding error.
reallocation, when junk filling is enabled. Junk filling must occur
prior to shrinking, since any deallocated trailing pages are immediately
available for use by other threads.
Reported by: Mats Palmgren <mats.palmgren@bredband.net>
allocation patterns, number of CPUs, and MALLOC_OPTIONS settings indicate
that lazy deallocation has the potential to worsen throughput dramatically.
Performance degradation occurs when multiple threads try to clear the lazy
free cache simultaneously. Various experiments to avoid this bottleneck
failed to completely solve this problem, while adding yet more complexity.
macros. The only semantic change was the need to add a vc_opened field
to struct vcomm since we can no longer use the request queue returning
to an uninitialized state to hold whether or not the device is open.

Bruce for putting lots of effort into these; getting them right isn't
easy, and they went through many iterations.
