f419891544 Rename the host-related prison fields to be the same as the host.*
parameters they represent, and the variables they replaced, instead of
abbreviated versions of them.

572db1408a Place hostnames and similar information fully under the prison system.
The system hostname is now stored in prison0, and the global variable
"hostname" has been removed, as has the hostname_mtx mutex.  Jails may
have their own host information, or they may inherit it from the
parent/system.  The proper way to read the hostname is via
getcredhostname(), which will copy either the hostname associated with
the passed cred, or the system hostname if you pass NULL.  The system
hostname can still be accessed directly (and without locking) at
prison0.pr_host, but that should be avoided where possible.

The "similar information" referred to is domainname, hostid, and
hostuuid, which have also become prison parameters and had their
associated global variables removed.

Obtained from:	Hideotshi Shimokawa

This update is based on comments from Hidetoshi.

Changeset 183550 removed the call to crom_load() in fw_busreset().  Restore
that call such that the Configuration ROM is valid.

Stash and update fwdev settings in fw_explore_node() so that negotiation
works again.

925ee6b32d Synopsis:
If speed of link between two devices is slower than the reported max
speed of both endpoints, the current driver will fail and be unable to
negotiate.

Summary:
Test negotiated speed by reading the CSRROM into a dummy variable.
If that read fails, decrement our speed and retry.  If all else fails,
go to lowest speed possible(0).

Report speed to the user.
Add display of the Bus Info Block when debug.firewire_debug > 1
Support the Bus Info Block(1394a-2000) method of speed detection.

I also should note that I am moving "hold_count" to 0 for future
releases.

This variable determines how many bus resets to "hold" a removed
firewire device before deletion.  I don't feel this is useful and will
probably drop support for this sysctl in the future.

70a17b78b0 Some updates and bug squashing in the firewire stack.
Move the interupt handler to a driver_intr_t type function as it was trying
to do way to much for a lightweight filter interrupt function.

Introduce much more locking around fc->mtx.  Tested this for lock reversals
and other such lockups.  Locking seems to be working better, but there
is much more to do with regard to locking.  The most significant lock is
in the BUS RESET handler.  It was possible, before this checkin, to set
a bus reset via "fwcontrol -r" and have the BUS RESET handler fire before
the code responsible for asserting BUS RESET was complete.  This locking
fixes that issue.

Move some of the memory allocations in the fc struct to the attach function
in firewire.c

Rework the businfo.generation indicator to be merely a on/off bit now.
It's purpose according to spec is to notify the bus that the config ROM
has changed.  That's it.

Catch and squash a possible panic in SBP where in the SBP_LOCK was held
during a possible error case.  The error handling code would definitely
panic as it would try to acquire the SBP_LOCK on entrance.

Catch and squash a camcontrol/device lockup when firewire drives go away.
When a firewire device was powered off or disconnected from the firewire
bus, a "camcontrol rescan all" would hang trying to poll removed devices
as they were not properly detached.  Don't do that.

8797d4caec Step 1.5 of importing the network stack virtualization infrastructure
from the vimage project, as per plan established at devsummit 08/08:
http://wiki.freebsd.org/Image/Notes200808DevSummit

Introduce INIT_VNET_*() initializer macros, VNET_FOREACH() iterator
macros, and CURVNET_SET() context setting macros, all currently
resolving to NOPs.

Prepare for virtualization of selected SYSCTL objects by introducing a
family of SYSCTL_V_*() macros, currently resolving to their global
counterparts, i.e. SYSCTL_V_INT() == SYSCTL_INT().

Move selected #defines from sys/sys/vimage.h to newly introduced header
files specific to virtualized subsystems (sys/net/vnet.h,
sys/netinet/vinet.h etc.).

All the changes are verified to have zero functional impact at this
point in time by doing MD5 comparision between pre- and post-change
object files(*).

(*) netipsec/keysock.c did not validate depending on compile time options.

1021d43b56 Commit step 1 of the vimage project, (network stack)
virtualization work done by Marko Zec (zec@).

This is the first in a series of commits over the course
of the next few weeks.

Mark all uses of global variables to be virtualized
with a V_ prefix.
Use macros to map them back to their global names for
now, so this is a NOP change only.

We hope to have caught at least 85-90% of what is needed
so we do not invalidate a lot of outstanding patches again.

51d643caa6 Rename the kthread_xxx (e.g. kthread_create()) calls
to kproc_xxx as they actually make whole processes.
Thos makes way for us to add REAL kthread_create() and friends
that actually make theads. it turns out that most of these
calls actually end up being moved back to the thread version
when it's added. but we need to make this cosmetic change first.

I'd LOVE to do this rename in 7.0  so that we can eventually MFC the
new kthread_xxx() calls.
