b4c618c099 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.

c3ab507fcd Return priority range 0..PRI_MAX_TIMESHARE-PRI_MIN_TIMESHARE for

it returns nice range -20 .. 20, nice should be treated as process
weight, it is really managed by getpriority() and setpriority()
syscalls, they are different.

b31da03fd8 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.

5908c617bb Several protocol switch functions (pru_abort, pru_detach, pru_sosetlabel)
return void, so don't implement no-op versions of these functions.
Instead, consistently check if those switch pointers are NULL before
invoking them.

f949ae9b31 When pru_attach() fails, call sodealloc() on the socket rather than
using sorele() and the full tear-down path.  Since protocol state
allocation failed, this is not required (and is arguably undesirable).
This matches the behavior of sonewconn() under the same circumstances.

337cc6b60e Reduce periods of simultaneous acquisition of various socket buffer
locks and the unplock during uipc_rcvd() and uipc_send() by caching
certain values from one structure while its locks are held, and
applying them to a second structure while its locks are held.  If
done carefully, this should be correct, and will reduce the amount
of work done with the global unp lock held.

55e9893a66 The ufs_lookup.c has a critical bug around the whiteout
process. UFS must check a whiteout name when it uses the
whiteout, but the current implementation does not check
the whileout name, so sometimes UFS writes over a wrong
whtieout. UFS *MUST* check the whiteout name to use a
corrent whiteout. This bug leads unionfs. panic.
This commit fixes this trouble.

8f68b4a607 Add a new flag to pmap_enter_locked() to say if it's OK to wait. If it is, and
we're unable to allocate the memory for a PTE, we'll wait until we can. If not,
we'll just return.
Use M_NOWAIT|M_USE_RESERVE to allocate PTEs, it is less aggressive than
M_NOWAIT alone.

c870740e09 - 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.
- Use the patched kern_recvit() to replace svr4_recvit() and the stock
  kern_sendit() to replace svr4_sendit().
- Use kern_bind() instead of stackgap use in ti_bind().
- Use kern_getpeername() and kern_getsockname() instead of stackgap in
  svr4_stream_ti_ioctl().
- Use kern_connect() instead of stackgap in svr4_do_putmsg().
- Use kern_getpeername() and kern_accept() instead of stackgap in
  svr4_do_getmsg().
- Retire the stackgap from SVR4 compat as it is no longer used.

a4690c931e Implement mpo_associate_nfsd_label entry point for the BIBA security policy,
we will initialize the label to biba/low for files that have been created
through an NFS RPC. This is a safe default given the default nature of our
NFS implementation, there is not a whole lot of data integrity there by
default. This also fixes kernel panics associated with file creation over NFS
while creating files on filesystems which have multilabel enabled with BIBA
enabled.

9a5af41076 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.
