what each of the fields is based on discussion with portmgr@.

Instead, explicitly enable them when we setup the interrupt handler.
Also, move the setting of stathz and profhz down to the same place so
that the code flow is simpler and easier to follow.
- Don't setup an interrupt handler for IRQ0 if we are using the lapic timer
as it doesn't do anything productive in that case.
Replace a KASSERT of LINUX_IFNAMSIZ == IFNAMSIZ with a preprocessor
check and #error message. This will prevent nasty suprises if users
change IFNAMSIZ without updating the linux code appropriatly.
LD_LIBMAP_DISABLE, LD_LIBRARY_PATH) are used, then make sure the
libraries being loaded aren't on a noexec-mounted filesystem.
This is a compromise position: I'm assuming that nobody will be silly
enough to set the noexec mount flag on part of the default library
path, in order to avoid adding extra overhead into the common case
(where those environment variables aren't used).

lockmgr locks that this thread owns. This is complicated due to
LK_KERNPROC and because lockmgr tolerates unlocking an unlocked lock.

these filesystems will support shared locks until they are explicitly
modified to do so. Careful review must be done to ensure that this
is safe for each individual filesystem.

flags and instead acquire an exclusive lock if they do not support
shared locks.

before it can call VOP_INACTIVE(). This must use the EXCLUPGRADE path
because we may violate some lock order with another locked vnode if
we drop and reacquire the lock. If EXCLUPGRADE fails, we mark the
vnode with VI_OWEINACT. This case should be very rare.
- Clear VI_OWEINACT in vinactive() and vbusy().
- If VI_OWEINACT is set in vgone() do the VOP_INACTIVE call here as well.

prefered that the option not leak out into filesystems when it is
disabled.

non-maskable).
- The NFS client needs to guard against spurious wakeups
while waiting for the response. ltrace causes the process
under question to wakeup (possibly from ptrace()), which
causes NFS to wakeup from tsleep without the response being
delivered.

disables tag queuing temporarily in order to allow controllers a window
to safely perform transfer negotiation with non-compliant devices. Before
this change, CAM would restore the queue depth to the controller specified
maximum or device quirk level rather than any depth determined by reactions
to QUEUE FULL/BUSY events or an explicit user setting.
During device probe, initialize the flags field for XPT_SCAN_BUS.
The uninitialized value often confused CAM into not bothering to
issue an AC_FOUND_DEVICE async event for new devices. The reason
this bug wasn't reported earlier is that CAM manually announces
devices after the initial system bus scans.

- Update the description of the cdrom.1 target and add notes for cdrom.2
and cdrom.3.
- Document CD_PACKAGES_TREE (CD_EXTRA_BITS wasn't documented before).
- Document CVSARGS.
- Remove DISC[12]_{LABEL,NAME}.
- Remove NOPORTREADMES.
- Remove references to drivers.conf files and man page.
- Update version number for a CURRENT snapshot to 6.0.
- When a separate livefs ISO is used, change the name of the tree directory
to be R/cdrom/livefs and change the name of the iso to livefs.iso rather
than using disc2. Instead, disc2 is now always going to be the packages
disc regardless of the presence of a separate livefs which makes things
simpler.
- Build a very simple disc2 tree under R/cdrom that just includes the
cdrom.inf file that the packages need. Also, build a disc2.iso image
in the iso.1 target. Disc 2's volume label is "FreeBSD_Packages".
- Retire CD_EXTRA_BITS and replace it with CD_PACKAGE_TREE. CD_EXTRA_BITS
was specific to disc1, but CD_PACKAGE_TREE instead should point to a
directory that has disc1 and disc2 subdirectories that contain the extra
bits for each image.
- Rename the bootonly volume label to "FreeBSD_bootonly" and just hardcode
the disc1 and livefs volume names and iso suffixes.
A Path is now a TAILQ of PathElements each of which just points to
a reference counted directory. Rename all functions dealing with Paths
from the Dir_ prefix to a Path_ prefix.
