Merge the gehenna-devsw branch into the trunk.
...
This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

RF_LOCK_MUTEX()/RF_UNLOCK_MUTEX() often cover more code than they

needs to. In particular, they often surround calls to malloc().
Re-work the locking on most macros to avoid this problem.
XXX: On MP systems, simultaneous calls to the GET macros when a
freelist is empty may cause that freelist to grow more quickly than
before. Given that the "increment" value of these lists are fairly
small, this shouldn't be too much of an issue.

Pool deals fairly well with physical memory shortage, but it doesn't
...
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map). Try to deal with this:
* Group all information about the backend allocator for a pool in a
separate structure. The pool references this structure, rather than
the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
to become available, but will still fail if it cannot callocate KVA
space for the pages. If this happens, carefully drain all pools using
the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
some pages, and use that information to make draining easier and more
efficient.
* Get rid of PR_URGENT. There was only one use of it, and it could be
dealt with by the caller.

rationalize the use of b_flags for geteblk() buffers.
...
rather than assigning to the whole field, set or clear individual flags,
which implies that the B_BUSY and B_INVAL flags will remain set.
this allows us to make the assertion in brelse() that B_BUSY is set,
which is the purpose of all this.

In the event that an up-to-date component cannot be located for a specific

Components which match on everything but the mod_counter are
...
renegades, and must be handled correctly. In particular, they should
be added to their old auto-config set, but then immediately released.
Failing to do otherwise means that they potentialy end up in a
different (and competing!) RAID set which may auto-configure in place
of the correct one, and cause all sorts of chaos at auto-configure
time.
