/proc/<pid>/statm.
These are only present when -o linux is specified as a mount option
to procfs.
Factor out some common code so that it can be used by a number of
functions.
XXX The values returned in the statm emulation need to be verified.
P_*/L_* naming convention, and rename the in-kernel flags to avoid
conflict. (P_ -> PK_, L_ -> LW_ ). Add back the (now unused) LSDEAD
constant.
Restores source compatibility with pre-newlock2 tools like ps or top.

First, remove process_checkioperm() calls from MD code. Similar checks
using kauth(9) routines (on the process scope, using appropriate action)
are done in the callers.
Add secmodel back-end to handle each subsystem.
- use vmspace rather than proc or lwp where appropriate.
the latter is more natural to specify an address space.
(and less likely to be abused for random purposes.)
- fix a swdmover race.
link points to the process's current working directory, and the root
link points to the process's root directory. What else would you
expect?
For directories that are out of reach (caller is in a chroot, target
process is in a different chroot, etc), the links point to "/"
instead.
1. Checking for a negative uio_offset at the beginning. This really does
not affect us in most cases because we check that later too.
2. Checking for attempts to write to init sooner and in all cases.

* Remove the "lwp *" argument that was added to vget(). Turns out
that nothing actually used it!
* Remove the "lwp *" arguments that were added to VFS_ROOT(), VFS_VGET(),
and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted
above, didn't use it).
* Remove all of the "lwp *" arguments to internal functions that were added
just to appease the above.

"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V

These changes will allow platforms like x86 (XMM) and PowerPC
(AltiVec) to export extended register sets in a sane manner.
* Use __HAVE_PTRACE_MACHDEP to export x86 XMM registers (standard
FP + SSE/SSE2) using PT_{GET,SET}XMMREGS (in the machdep
ptrace request space).
* Use __HAVE_PROCFS_MACHDEP to export x86 XMM registers via
/proc/N/xmmregs in procfs.
adjusted via sysctl. file systems that have hash tables which are
sized based on the value of this variable now resize those hash tables
using the new value. the max number of FFS softdeps is also recalculated.
convert various file systems to use the <sys/queue.h> macros for
their hash tables.
