the msgctl, semctl, and shmctl system calls. This moves the old
versions to COMPAT_35 and adds new ones.
WARNING: While this fixes things like shared memory in the X server
for old (pre-mode_t change) binaries, it will break binaries that
use shared memory built between the time of the mode_t change (Jul
13th) and now. If you rebuild X during that interval you will need
to do it again after updating the rest of userland.

which also takes two function pointers for copyin/copyout. For the
real syscalls these are just the normal copyin/copyout functions.
For the compat routines, these are funtions that convert between
the new and old foo_ds structs automagically. OK deraadt@

use mode_t in syscalls.master and to use mode_t in more places in
the kernel. It also makes lint much more useful on kernel code.
I've also added a placeholder for st_birthtime to make a UFS2 import
easier at some future date.

the argv[0] would be normalized, and hence break scripts
that depend on how they were called.
this fixes an issue in the ports builds.

Add trivial support for passing a NULL pointer for the argv buffer;
currently just returns ARG_MAX for KERN_PROC_ARGV and KERN_PROC_ENV.

encapsulating all such access into wall-defined functions
that makes sure locking is done as needed.
It also cleans up some uses of wall time vs. uptime some
places, but there is sure to be more of these needed as
well, particularily in MD code. Also, many current calls
to microtime() should probably be changed to getmicrotime(),
or to the {,get}microuptime() versions.

- add an exec message so that whenever a set-uid/gid process
exec's a new image which we may control, the exec does not
go by unnoticed.
- take special care to check for P_SUGIDEXEC as well as
P_SUGID, corresponding to the same changes that were made in
the ptrace code a while ago
ok niels@, sturm@; thanks to naddy for testing

things such that code that only need a second-resolution uptime or wall
time, and used to get that from time.tv_secs or mono_time.tv_secs now get
this from separate time_t globals time_second and time_uptime.

Also, add an assert-like function to sprinkle in code you're debugging at the
moment. Those asserts are _not_ supposed to be ever comitted, just use them
while debugging.

in reality, sometimes it's not. we don't trust vnlock, and since it's 100%
guaranteed to panic if it gets here, just completely stop using it.

Introduce the cpu_info structure, p_cpu field in struct proc and global
scheduling context and various changed code to deal with this. At the
moment no architecture uses this stuff yet, but it will allow us slow and
controlled migration to the new APIs.
All new code is ifdef:ed out.

remove alpha specific definition of ncpus.
OK (and tested on alpha) deraadt@

the new one remains the default and _nointr.
_kmem is restored to its former position, and _oldnointr is
introduced.
this is to allow some pool users who don't like the new allocator
to continue working. testing/ok beck@ cedric@

The hotplug pseudo-device passes device attachment and detachment events
to userland. When a device attaches or detaches, the corresponding event
is queued. The events can then be obtained from the queue through the
read(2) call on the /dev/hotplug device file. Each event consists of
event type (attach/detach), device class (DV_*) and device name (sd1 e.g.).
We have hotplug pseudo-device on alpha, amd64, i386, macppc and sparc64.
Since it was tested only on i386 other archs has it commented out
in GENERIC until tested.
The idea liked peter@ tedu@ drahn@ millert@ marco@ henning@.

update cpu even with 100 -> 100 setperf changes, in case saved value
has gotten out of sync. from grange@ ok deraadt@ grange@

change both the nointr and default pool allocators to using uvm_km_getpage.
change pools to default to a maxpages value of 8, so they hoard less memory.
change mbuf pools to use default pool allocator.
pools are now more efficient, use less of kmem_map, and a bit faster.
