message. Otherwise, the boot attempt will fail with a BTX fault when
trying to read the EFER MSR.

netisr or ithread's socket buffer size limit is not the right limit to
use. Instead, pass NULL as the other two calls to sbreserve_locked()
in the TCP input path (tcp_mss()) do.
In practice, this is a no-op, as ithreads and the netisr run without a
process limit on socket buffer use, and a NULL thread pointer leads to
not using the process's limit, if any. However, if tcp_input() is
called in other contexts that do have limits, this may prevent the
incorrect limit from being used.

code. Added a copyright for the work I did to this file a couple of
years ago. Add John's copyright too, since I'm sure I'll be pulling
more into this code. This also implements a new -n option to not
allow breaking into the boot sequence which was original in the patch
John posted (not in the original i386 code I based this boot2.c on,
only the name is the same). I haven't checked to see if he did that,
or if it was one of Sam's improvements.

- Add support for .Fx, just in case somebody starts using it.
- Only add the arch information to the first para per manual page.
This improves output for axe(4), and generally seems to make sense
(I hope).
- Remove an unneeded line for non-compat mode.
This removes some vertical whitespace in the output.
Whitespace was intentionally not fixed in the SGML for the related
lists, to make the actual change more clear. This file is in need of
a major whitespace cleanup anyway.
single stepped the process to the system call), we need to clear
the trap flag from the new frame. Otherwise, the new thread will
receive a (likely unexpected) SIGTRAP when it executes the first
instruction after returning to userland.
booting from an MFS root (e.g. from an install CD) firmware_mountroot
can be called twice with the second call happening before the task
callback occurs; this results in the task structure contents being
corrupted because it was declared static.

syscalls expect the bitmap size in the range from 32 to 128. Old glibc
always assumed size 1024, while newer glibc searches for approriate
size, starting from 1024 and going up.
For now, use FreeBSD size of cpuset_t for bitmap size parameter and
return EINVAL if length of user space bitmap less than our size of
cpuset_t.

This means that inp_cred is always there, even after the socket
has gone away. It also means that it is constant for the lifetime
of the inp.
Both facts lead to simpler code and possibly less locking.
