The p_can(...) construct was a premature (and, it turns out,
awkward) abstraction. The individual calls to p_canxxx() better
reflect differences between the inter-process authorization checks,
such as differing checks based on the type of signal. This has
a side effect of improving code readability.
o Replace direct credential authorization checks in ktrace() with
invocation of p_candebug(), while maintaining the special case
check of KTR_ROOT. This allows ktrace() to "play more nicely"
with new mandatory access control schemes, as well as making its
authorization checks consistent with other "debugging class"
checks.
o Eliminate "privused" construct for p_can*() calls which allowed the
caller to determine if privilege was required for successful
evaluation of the access control check. This primitive is currently
unused, and as such, serves only to complicate the API.

PCI bus object. This should deal both with already-routed interrupts
as well as devices that need an interrupt routed.
Note that it *doesn't* deal with interlocked interrupt dependancies, nor
does it select between interrupt options in a smart way. These are
optimisations that need further work.
is a parallel adjunct to active cooling, not a lesser evil. The _ACx
levels sort from 0 being hottest, not coolest.
Sanity check the returned temperature values, since we are having
trouble reading them on some systems.
Rearrange sysctl nodes a bit; this is probably close to the final layout.
Also removed some spl's and added some VM mutexes, but they are not actually
used yet, so this commit does not really make any operational changes
to the system.
vm_page.c relates to vm_page_t manipulation, including high level deactivation,
activation, etc... vm_pageq.c relates to finding free pages and aquiring
exclusive access to a page queue (exclusivity part not yet implemented).
And the world still builds... :-)
destroyed properly (otherwise bad things would happen after a clone
dev had been created, and the module was kldunloaded). Allocated
children that have not successfully probed are being deleted again
(otherwise fd0 and fd1 have always been allocated, even if only
fd0 was acutally present, and fd1 even survived kldunloading the
module).
Still, kldunloading leaves remnants of the previously existing devices
intact. Why doesn't it destroy all the devices? As a consequence,
since dev->descr now points into no longer allocated memory, the
system panics deep inside printf(9) when running devinfo(1) after
kldunloading the module. Ideas sought...
Also, when kldloading the module on a hints-populated isab0, this bus
somehow has already created an fdc0 entry (a dummy) so the load
attempt fails and will register fdc1 instead. What are those dummy
entries for? Loading the module from the bootloader works, and it
can be unloaded an re-loaded then later.
most of these inlines had been bloated in -current far beyond their
original intent. Normalize prototypes and function declarations to be ANSI
only (half already were). And do some general cleanup.
(kernel size also reduced by 50-100K, but that isn't the prime intent)
For fibre channel, start going for the gusto and using AC_FOUND_DEVICE
and AC_LOST_DEVICE calls to xpt_async when devices appear and disappear
as the loop or fabric changes.
ISPASYNC_FW_CRASH is the async event code where the platform layer
deals with a firmware crash.
some of the RIO (reduced interrupt operation) stuff. Add 64 bit
data list (DSD type 1) and arbitrary data list (DSD type 2)
data structure defines.
Add macros that parameterize usage of the Request/Response in/out
queue pointers. When we finish 2300 support, different registers
will be accessed for the 2300.
part of the PCI block for the 2300- not software convention usage
of the mailbox registers- so we macrosize in/out pointer usage.
Only report that a LIP destroyed commands if it actually destroyed
commands. Get the chan/tgt/lun order correct. Fix a longstanding
stupid bug that caused us to try and issue a command with a tag on
Channel B because we were checking the tagged capability for the
target against Channel A.
A firmware crash is now vectored out to platform specific code
as an async event.
Some minor formatting tweaks.
(this commit is just the first stage). Also add various GIANT_ macros to
formalize the removal of Giant, making it easy to test in a more piecemeal
fashion. These macros will allow us to test fine-grained locks to a degree
before removing Giant, and also after, and to remove Giant in a piecemeal
fashion via sysctl's on those subsystems which the authors believe can
operate without Giant.
- Move the lance_probe function to if_lnc.c.
- Support C-NET(98)S again.

These take an additional mutex argument, which is dropped before any
processes are made runnable. This can avoid contention on the mutex
if the processes would immediately acquire it, and is done in such a
way that wakeups will not be lost.
