58d2b4c193 Fix panic when module is compiled in and it is loaded from loader.conf.
Only panic is fixed, module will be still listed in kldstat(8) output.
Not sure what is correct fix, because adding unloading code in case of
failure to linker_init_kernel_modules() doesn't work.

2add4b872d Change the way options are parsed on the `#!'-line of a shell-script. Instead
of having the kernel parse that line and add an entry to the argument list for
each 'separate word' it finds, have it add only one entry which holds all
the words found on that line.  The old behavior is useful in some situations,
but it does not match the way any other operating system will parse that line.

This has been discussed in the thread "Bug in #! processing - One More Time"
on the freebsd-arch mailing list (starting back on Feb 24, 2005).  The first
few messages in that thread provide the background in much detail.

ceb26b4c48 Mark the following compatability system calls as MCOMPAT or MCOMPAT4 based

system calls:

  getfsstat()
  lseek()
  stat()
  lstat()
  truncate()
  ftruncate()
  statfs()
  fstatfs()

Note that ogetdirentries() is not marked MPSAFE because it does not share
the MPSAFE implementation used for getdirentries(), and requires separate
locking to be implemented.

65ffcee053 - Add support to the loader for multiple consoles.
- Teach the i386 and pc98 loaders to honor multiple console requests from
  their respective boot2 binaries so that the same console(s) are used in
  both boot2 and the loader.
- Since the kernel doesn't support multiple consoles, whichever console is
  listed first is treated as the "primary" console and is passed to the
  kernel in the boot_howto flags.

ac1a365e2d In the current world order, each socket has two mutexes: a mutex
that protects socket and receive socket buffer state, and a second
mutex to protect send socket buffer state.  In some places, the
mutex shared between the socket and receive socket buffer will be
acquired twice, once by each layer, resulting in some
inconsistency, but providing the abstraction benefit of being able
to more easily separate the two mutexes in the future if desired.

When transitioning a socket to the SS_ISDISCONNECTING or
SS_ISDISCONNECTED states, grab the socket/receive socket buffer lock
once rather than grabbing it as the socket lock, modifying socket
state, then grabbing a second time as the receive lock in order to
modify the socket buffer state to indicate no further data can be
read.  This change is believed to close a race between the change in
socket state and the change in socket buffer state, which for a
remotely initiated close on a UNIX domain socket, resulted in
soreceive() returning ENOTCONN rather than an EOF condition.

A similar race still exists in the case of send, however, and is
harder to fix as the socket and send socket buffer mutexes are not
the same, and we would like to avoid holding combinations of socket
mutexes over sb_upcall until we've finished clarifying the locking
protocol for upcalls.

This change has the side affect of reducing the number of mutex
operations to initiate disconnect or perform disconnect on a
socket by two.

46520b8295 Back out ipx.h:1.18, which introduced a Linux API compatibility field in
the ipx_net data structure.  Doing so introduced a stronger alignment
requirement for the address structure, which in turn propagated into
other dependent data structures, which turns out not to be suported by
the available IPX source code.  As a result, a number of user space
applications, such as IPX routing components, failed to operate
correctly.
