and output, set BUS_DMA_COHERENT when creating the DMA map used for
loading the buffer. As a side-effect this solves locking issues on
sparc64 when dcons(4) calls bus_dmamap_sync(9) while in an interrupt
filter, which are executed in a critical section, and iommu(4) has
to use a sleep lock when taking advantage of the streaming buffer.

For some reason the nmdm(4) driver doesn't use CALLOUT_MPSAFE, even
though we live in the MPSAFE TTY era. Add the CALLOUT_MPSAFE flags.

for virtualization.
Instead of initializing the affected global variables at instatiation,
assign initial values to them in initializer functions. As a rule,
initialization at instatiation for such variables should never be
introduced again from now on. Furthermore, enclose all instantiations
of such global variables in #ifdef VIMAGE_GLOBALS blocks.
Essentialy, this change should have zero functional impact. In the next
phase of merging network stack virtualization infrastructure from
p4/vimage branch, the new initialization methology will allow us to
switch between using global variables and their counterparts residing in
virtualization containers with minimum code churn, and in the long run
allow us to intialize multiple instances of such container structures.

- An "at" hint now reserves a device name.
- A new BUS_HINT_DEVICE_UNIT method is added to the bus interface. When
determining the unit number of a device, this method is invoked to
let the bus driver specify the unit of a device given a specific
devclass. This is the only way a device can be given a name reserved
via an "at" hint.
- Implement BUS_HINT_DEVICE_UNIT() for the acpi(4) and isa(4) bus drivers.
Both of these busses implement this by comparing the resources for a
given hint device with the resources enumerated by ACPI/PnPBIOS and
wire a unit if the hint resources are a subset of the "real" resources.
- Use bus_hinted_children() for adding hinted devices on isa(4) busses
now instead of doing it by hand.
- Remove the unit kludging from sio(4) as it is no longer necessary.

This bring huge amount of changes, I'll enumerate only user-visible changes:
- Delegated Administration
Allows regular users to perform ZFS operations, like file system
creation, snapshot creation, etc.
- L2ARC
Level 2 cache for ZFS - allows to use additional disks for cache.
Huge performance improvements mostly for random read of mostly
static content.
- slog
Allow to use additional disks for ZFS Intent Log to speed up
operations like fsync(2).
- vfs.zfs.super_owner
Allows regular users to perform privileged operations on files stored
on ZFS file systems owned by him. Very careful with this one.
- chflags(2)
Not all the flags are supported. This still needs work.
- ZFSBoot
Support to boot off of ZFS pool. Not finished, AFAIK.

- Snapshot properties
- New failure modes
Before if write requested failed, system paniced. Now one
can select from one of three failure modes:
- panic - panic on write error
- wait - wait for disk to reappear
- continue - serve read requests if possible, block write requests
- Refquota, refreservation properties
Just quota and reservation properties, but don't count space consumed
by children file systems, clones and snapshots.
- Sparse volumes
ZVOLs that don't reserve space in the pool.
- External attributes
Compatible with extattr(2).
- NFSv4-ACLs
Not sure about the status, might not be complete yet.

read before we configure the card, so we can implement
/dev/cardbus*.cis. Also, do this on a per-child basis, so we now have
a different name than before. I think i'll have to fix that for some
legacy tools to keep working.
I can now do a dumpcis on my running atheros card and have it still work!
kern_unlinkat(), that expects that vn_start_write() actually fills the mp
even when the call failed.
As Tor noted, that pattern relies on the the type stability of the mount
points, as well as that suspended mount points are never freed and
V_XSLEEP is always passed to vn_start_write() when called on a freed
mount point.

class CPUs. In theory one could also use versions additionally
taking advantage of the prefetch cache with cheetah-class CPUs,
in my worldstone runs these either didn't provide extra speedup
(USIII+) in comparison to the existing spitfire versions or were
even slightly slower (USIIIi) though, so they aren't committed
for now.
The basic problem leading to the VIS-based copy/zero functions
being initially disabled for cheetah-class CPUs was solved by
letting cheetah_init() clear DCR_IFPOE.
