a72b0bcd7f Simplify the pager support in DDB. Allowing different db commands to
install custom pager functions didn't actually happen in practice (they
all just used the simple pager and passed in a local quit pointer).  So,
just hardcode the simple pager as the only pager and make it set a global
db_pager_quit flag that db commands can check when the user hits 'q' (or a
suitable variant) at the pager prompt.  Also, now that it's easy to do so,
enable paging by default for all ddb commands.  Any command that wishes to
honor the quit flag can do so by checking db_pager_quit.  Note that the
pager can also be effectively disabled by setting $lines to 0.

Other fixes:
- 'show idt' on i386 and pc98 now actually checks the quit flag and
  terminates early.
- 'show intr' now actually checks the quit flag and terminates early.

9a40fa9b7b Fix config page writes to not strip out the attributes when you
actually go write the config page. This fixes the long standing
problem about updating NVRAM on Fibre Channel cards and seems
so far to not break SPI config page writes.

Put back role setting into mpt. That is, you can set a desired role
for mpt as a hint. On the next reboot, it'll pick that up and redo
the NVRAM settings appropriately and warn you that this won't take
effect until the next reboot. This saves people the step of having
to find a BIOS utilities disk to set target and/or initiator role
for the MPT cards.

21e00b8d70 Assume floppy disk is not inserted when we have exhausted retries. This
significantly reduces booting time when there is broken floppy disk drive,
controller, cable, BIOS, etc.
When the floppy controller interface is correctly implemented, disk change
signal (DSKCHG) is reflected in the Digital Input Register (DIR) at 0x3f7.
However, there are many cases that the signal is unusable.  Moreover, some
BIOS does not reserve the port at all.  In those cases, the register may not
function.

cfc179a934 - Split out kern_accept(), kern_getpeername(), and kern_getsockname() for
use by ABI emulators.
- Alter the interface of kern_recvit() somewhat.  Specifically, go ahead
  and hard code UIO_USERSPACE in the uio as that's what all the callers
  specify.  In place, add a new uioseg to indicate what type of pointer
  is in mp->msg_name.  Previously it was always a userland address, but
  ABI emulators may pass in kernel-side sockaddrs.  Also, remove the
  namelenp field and instead require the two places that used it to
  explicitly copy mp->msg_namelen out to userland.

a6dea567ad Convert isp(4) and ispfw(4) to use firmware(9) to manage firmware
loading for the QLogic cards.

Because isp(4) exists before the root is mounted, it's not really
possible for us to use the kernel's linker to load modules directly
from disk- that's really too bad.

However, the this is still a net win in in that the firmware has
been split up on a per chip (and in some cases, functionality)
basis, so the amount of stuff loaded *can* be substantially less
than the 1.5MB of firmware images that ispfw now manages. That is,
each specific f/w set is now also built as a module. For example,
QLogic 2322 f/w is built as isp_2322.ko and Initiator/Target 1080
firmware is built as isp_1080_it.ko.

For compatibility purposes (i.e., to perturb folks the least), we
also still build all of the firmware as one ispfw.ko module.

This allows us to let 'ispfw_LOAD' keep on working in existing
loader.conf files. If you now want to strip this down to just
the firmware for your h/w, you can then change loader.conf to
load the f/w you specifically want.

We also still allow for ispfw to be statically built (e.g., for
PAE and sparc64).

Future changes will look at f/w unloading and also role switching
that then uses the kernel linker to load different ips f/w sets.

094306d69d - Split ioctl() up into ioctl() and kern_ioctl(). The kern_ioctl() assumes
that the 'data' pointer is already setup to point to a valid KVM buffer
  or contains the copied-in data from userland as appropriate (ioctl(2)
  still does this).  kern_ioctl() takes care of looking up a file pointer,
  implementing FIONCLEX and FIOCLEX, and calling fi_ioctl().
- Use kern_ioctl() to implement xenix_rdchk() instead of using the stackgap
  and mark xenix_rdchk() MPSAFE.

5e8693a976 Rework kern_semctl a bit to always assume the UIO_SYSSPACE case. This
mostly consists of pushing a few copyin's and copyout's up into
__semctl() as all the other callers were already doing the UIO_SYSSPACE
case.  This also changes kern_semctl() to set the return value in a passed
in pointer to a register_t rather than td->td_retval[0] directly so that
callers can only set td->td_retval[0] if all the various copyout's succeed.

As a result of these changes, kern_semctl() no longer does copyin/copyout
(except for GETALL/SETALL) so simplify the locking to acquire the semakptr
mutex before the MAC check and hold it all the way until the end of the
big switch statement.  The GETALL/SETALL cases have to temporarily drop it
while they do copyin/malloc and copyout.  Also, simplify the SETALL case to
remove handling for a non-existent race condition.

f7c9fd2027 Create bus_enumerate_hinted_children. This routine will allow drivers
to use the hinted child system.  Bus drivers that use this need to
implmenet the bus_hinted_child method, where they actually add the
child to their bus, as they see fit.  The bus is repsonsible for
getting the attribtues for the child, adding it in the right order,
etc.  ISA hinting will be updated to use this method.

7a3e252286 Fix semctl(2) breakage from the previous commit. Previously __semctl() had
a local 'semid' variable which was the array index and used uap->semid
as the original IPC id.  During the kern_semctl() conversion those two
variables were collapsed into a single 'semid' variable breaking the
places that needed the original IPC ID.  To fix, add a new 'semidx'
variable to hold the array index and leave 'semid' unmolested as the IPC
id.  While I'm here, explicitly document that the (undocumented, at least
in semctl(2)) SEM_STAT command curiously expects an array index in the
'semid' parameter rather than an IPC id.

4a15289bc1 Detach the interface first, do vlan_unconfig() then.
Previously, another thread could get a pointer to the
interface by scanning the system-wide list and sleep
on the global vlan mutex held by vlan_unconfig().
The interface was gone by the time the other thread
woke up.

In order to be able to call vlan_unconfig() on a detached
interface, remove the purely cosmetic bzero'ing of IF_LLADDR
from the function because a detached interface has no addresses.

a6f981face A small race existed where the lock was dropped between when encif was
tested and then set. [1]

Reorganise things to eliminate this, we now ensure that enc0 can not be
destroyed which as the benefit of no longer needing to lock in
ipsec_filter and ipsec_bpf. The cloner will create one interface during the
init so we can guarantee that encif will be valid before any SPD entries are
added to ipsec.

a105603f02 Properly detect the RTL8168(B?) again. RealTek sent me a bunch of sample
cards: the chips are all marked "RTL8111B", but they put stickers on the
back that say "RTL8168B/8111B". The manual says there's only one HWREV code
for both the 8111B and 8168B devices, which is 0x30000000, but the cards
they sent me actually report HWREV of 0x38000000. Deciding to trust the
hardware in front of me rather than a possibly incorrect manual (it wouldn't
be the first time the HWREVs were incorrectly documented), I changed the
8168 revision code. It turns out this was a mistake though: 0x30000000
really is a valid for the 8168.

There are two possible reasons for there to be two different HWREVs:

1) 0x30000000 is used only for the 8168B and 0x38000000 is only for
   the 8111B.
2) There were 8111/8168 rev A devices which both used code 0x30000000,
   and the 8111B/8168B both use 0x38000000.

The product list on the RealTek website doesn't mention the existence of
any 8168/8111 rev A chips being in production though, and I've never seen
one, so until I get clarification from RealTek, I'm going to assume that
0x30000000 is just for the 8168B and 0x38000000 is for the 8111B only.

So, the HWREV code for the 8168 has been put back to 0x30000000,
a new 8111 HWREV code has been added, and there are now separate
entries for recognizing both devices in the device list. This will
allow all devices to work, though if it turns out I'm wrong I may
need to change the ID strings

6131479c85 Updated the XBOX kernel to use the new nfe(4) driver obtained from
OpenBSD. This driver seems to give a small performance increase, and
should lead to better maintainability in the future.

The nForce Ethernet-specific hack in sys/i386/xbox/xbox.c is still
required, judging from dev/nfe/if_nfe.c. The condition it hacks will
almost certainly only occur on XBOX-es anyway, so it is best left there.

 - some page fault stats
 - time spend in kernel/userland
 - priority/nice value
 - starttime [1]
 - memory/swap stats
 - scheduling policy

Additionally add some new fields and correct some not filled out ones.

This brings us down to 15 dummy fields.

The fields marked with [1] are needed to get Oracle 10 running. The starttime
field is not completely right, since it displays the _same_ starttime for
_every_ process, but at least it is not 0 and Oracle accepts this.

This is a RELENG_x_y candidate.
