table with console settings, we now only need to know at which
address the UART lives. Leaving the baudrate unspecified results
in us using the baudrate at which the UART operates. This removes
one parameter that can interfere with a successful installation
out of the box.
current baudrate setting. Use this ioctl() when we don't know the
baudrate of the sysdev (as represented by a 0 value). When the
ioctl() fails, e.g. when the backend hasn't implemented it or the
hardware doesn't provide the means to determine its current baudrate
setting, we invalidate the baudrate setting by setting it to -1.
None of the backends currently implement the new ioctl().
A baudrate we consider insane is silently replaced with 0. When the
baudrate is 0, we will not try to program the hardware. Instead we
leave the communication speed unaltered, maximizing the chance to
have a working console. Obviously this means we allow specifying a
0 baudrate for exactly that purpose.
In the old world (as the surrounding comment in makefile says), there
was the /usr/libexec/ld-elf.so.1 binary which is now a symlink to
/libexec/ld-elf.so.1. To symlink, we need to make sure that the
_target_ (and the target is /usr/libexec/ld-elf.so.1) doesn't have
"schg" flag set. A real solution is to protect the chflags call only if
target exists, like we do in usr.bin/tip/tip/Makefile.

- Because em_encap() can now fail in a way that leaves us without an
mbuf chain, potentially set *m_headp to NULL if that happens, so that
the caller can do the right thing. This case can occur when we try
to prepend the vlan header mbuf but can't allocate additional memory.
- Modify the caller of em_encap() to detect a NULL m_head and not try
to queue the mbuf if that happens.
- When em_encap() fails, make sure to call bus_dmamap_destroy() to
clean up.
but sk(4) is so prevalent on AMD64 motherboards we need to reduce the number
of round trips in the mailing lists trying to get sufficient information to
make sure we've got a handle on all the problems and are working towards
making sk(4) solid.

The size_t type is better suited for that, particularly because
the "blksize" argument is to be passed to malloc() and read().
On 64-bit archs it's more to a style issue, but the good style
of coding in C is also important.
Use this in all the places where sleeping with the lock held is not
an issue.
The distinction will become significant once we finalize the exact
lock-type to use for this kind of case.

unconditionally. The first change was merged accidentally as part of
the larger set of changes to introduce MAC labels and access control,
and potentially lead to continued processing of a request even after
it was determined to be invalid. The second change was due to changes
in the semaphore code since the original work was performed.
