Allows memory walks to function.

and add an 'rtableid' keyword to ps.
Add rtable id, thread id, and socket splice info to struct kinfo_file2
and make fstat display socket splice information.
Remove old KVM_PROC2 and kinfo_proc2 interfaces; bump libkvm major
Socket splice info and corrections from bluhm@ "Lovely" deraadt@

vmmap is designed to perform address space randomized allocations,
without letting fragmentation of the address space go through the roof.
Some highlights:
- kernel address space randomization
- proper implementation of guardpages
- roughly 10% system time reduction during kernel build
Tested by alot of people on tech@ and developers.
Theo's machines are still happy.

in libkvm with the stable-ABI versions that are currently named
KERN_PROC2, kvm_get{proc,argv,envv}2(). The latter names and symbols
will continue to be supported for a few releases.
Committing now that they ports people have had a couple releases
to update pkgs that usd the old functions

so that the process-level stuff is to/from struct process and not
struct proc. This fixes a bunch of problem cases in rthreads.
Based on earlier work by blambert and myself, but mostly written
at c2k10.
Tested by many: deraadt, sthen, krw, ray, and in snapshots

/dev/mem to be direct instead of going through kvm_getprocs(), as
that function is going to get more an more broken as we move stuff
from struct proc to struct process for rthreads. To minimize the
code copying, put the common logic of filling in a kinfo_proc2
structure into a macro FILL_KPROC2() in <sys/sysctl.h> for use from
both the kernel and user-space. This also hides the KERN_PROC
#define behind "#if defined(_KERNEL)||defined(_LIBKVM)", as it's
deprecated.
Positive feedback from millert and blambert; so committing to unblock
further rthreads work.

unmaintainable). these days, people use source. these id's do not provide
any benefit, and do hurt the small install media
(the 33,000 line diff is essentially mechanical)
ok with the idea millert, ok dms

access the swap area. Change kvm_open() to no longer require a swap area,
and to not consider failure to open() it as fatal. Post-mortem analysis
would need an image of the swap area at the time of the crash, anyway.

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.
OK deraadt@

- Move the functionality of choosing a process from cpu_switch into
a much simpler function: cpu_switchto. Instead of having the locore
code walk the run queues, let the MI code choose the process we
want to run and only implement the context switching itself in MD
code.
- Let MD context switching run without worrying about spls or locks.
- Instead of having the idle loop implemented with special contexts
in MD code, implement one idle proc for each cpu. make the idle
loop MI with MD hooks.
- Change the proc lists from the old style vax queues to TAILQs.
- Change the sleep queue from vax queues to TAILQs. This makes
wakeup() go from O(n^2) to O(n)
there will be some MD fallout, but it will be fixed shortly.
There's also a few cleanups to be done after this.

ckuethe@ for a while. Okay beck@, "it is good timing" deraadt@.

us did not see it or get a chance to test it before it was commited. It
broke cvs, in the ami driver, making it not succeed at seeing it's devices.

this results in lesse kva waste due to static preallocation of those
for every phys page and also every swap page.
tested by beck krw miod

I've skipped the GNU stuff for now. From Patrick Latifi.

- actually use the value we've just reallocated.
- Don't return success just because the error wasn't ENOMEM (doh!).

show them with -k. Do not try to show RSS based values for them as they
mess up column alignment. vmstat -f now shows kernel threads separately
from rforks too.
