environ[0] to be more obvious that environ is not NULL before environ[0]
is tested. Although I believe the previous code worked, this change
improves code maintainability.

big endian platforms where time_t is 64bits (ie armeb and sparc64), it will
be a problem.
Use a temporary time_t to work around this.

Stir directly from the kernel PRNG, without taking less random pid & time
bytes too (when it is possible).
The difference with OpenBSD code is that they have KERN_ARND sysctl for
that task, while we need to read /dev/random
lstat(2) is called on symlinks -- this code appears never to have
worked. The PR this addresses suggests that the intended
original behavior is the right one, but as bde points out in the
PR comments, we do actually support storing a mode on symlinks,
so returning it seems reasonable.
This is consistent with Mac OS X, which despite documentation to
the contrary does return the mode set on a symlink, but not some
other platforms. The Single Unix Spec requires only that the
returned bits be "meaningful", which seems at best unhelpful as
advice goes.

vnode lock may cause a LOR between kld_sx lock and vnode lock.
linker_load_dependencies() drops kld_sx, and another thread may attempt
to load the same kld.

As clearly mentioned on the mailing lists, there is a list of drivers
that have not been ported to the MPSAFE TTY layer yet. Remove them from
the kernel configuration files. This means people can now still use
these drivers if they explicitly put them in their kernel configuration
file, which is good.
People should keep in mind that after August 10, these drivers will not
work anymore. Even though owners of the hardware are capable of getting
these drivers working again, I will see if I can at least get them to a
compilable state (if time permits).
- When y/x is huge, it's faster and more accurate to return pi/2
instead of pi - pi/2.
- There's no need for 3 lines of bit fiddling to compute -z.
- Fix a comment.
yank it's description; likewise for the FIRMWARE_WAIT flag to firmware_put.
For the record, the last commit was to cleanup various mistakes and correct
the example of embedding to reflect the npe firmware now being distributed
with the system.
code interfered with Performant mode and legacy interrupts. Also
remove a register read operation on the Simplq code that was
effectively a time-wasting no-op.
