not properly set up. r199067 added the call to TUNABLE_INT_FETCH() to
initializecpu() that results in hang because AP are started when kernel
environment is already dynamic and thus needs to acquire mutex, that is
too early in AP start sequence to work.
Extract the code that should be executed only once, because it sets
up global variables, from initializecpu() to initializecpucache(),
and call the later only from hammer_time() executed on BSP. Now,
TUNABLE_INT_FETCH() is done only once at BSP at the early boot stage.

Clean up the ttys files shipped with PicoBSD, NanoBSD and TinyBSD. While
there, it seems one of them still had references to sio(4). Make it in
sync with what we do in the base system.
Right now syscons(4) uses a cons25-style terminal emulator. The
disadvantages of that are:
- Little compatibility with embedded devices with serial interfaces.
- Bad bandwidth efficiency, mainly because of the lack of scrolling
regions.
- A very hard transition path to support for modern character sets like
UTF-8.
Our terminal emulation library, libteken, has been supporting
xterm-style terminal emulation for months, so flip the switch and make
everyone use an xterm-style console driver.
I still have to enable this on i386. Right now pc98 and i386 share the
same /etc/ttys file. I'm not going to switch pc98, because it uses its
own Kanji-capable cons25 emulator.
IMPORTANT: What to do if things go wrong (i.e. graphical artifacts):
- Run the application inside script(1), try to reduce the problem and
send me the log file.
- In the mean time, you can run `vidcontrol -T cons25' and `export
TERM=cons25' so you can run applications the same way you did before.
You can also build your kernel with `options TEKEN_CONS25' to make all
virtual terminals use the cons25 emulator by default.

from CD on 64-bit hardware to replace existing band-aids. This occurred
when the preloaded mdroot required too many mappings for the static
buffer.
Since we only use the translations buffer once, allocate a dynamic
buffer on the stack. This early in the boot process, the call chain
is quite short and we can be assured of having sufficient stack space.

That results useful when using serial lines sending garbage and leading
to unwilling boot prompt appearence.

on the assumption that the unit linked with the device is invariant but
that can change when calling devclass_alloc_unit() (because -1 is passed
or, more simply, because the unit choosen is beyond the table limits).
This results in a completely bogus string building.
Fix this by reserving the necessary room for all the possible characters
printable by a positive integer (we do not allow for negative unit
number).

page fault panic on initialization due to a large
number of bounce pages being allocated. This is due
to the dma tag requiring page alignment on mbuf mapping.
This was removed some time back from the ixgbe driver
and is not needed here either.
first part of a verifier is set to the first IP address from
V_in_ifaddrhead list. This address is typically the loopback address
making the first part of the verifier practically non-unique. The second
part of the verifier is initialized to zero making its initial value
non-unique too.
This commit changes the strategy for create verifier initialization:
just initialize it to a random value. Also move verifier handling into
its own function and use a mutex to protect the variable.
This change is a candidate for porting to sys/nfsclient.
