5abbf990f3 Change reboot(2) to take two arguments: bootopt like normal and also 
a boot string for firmware that can do this, such as the SPARC and
the sun3 models.  It is currently silently ignored on all other
hardware now, however.  The MD function "boot()" has been changed to
also take a char *.

value if we're not concerned with boundary checking.  Avoids a stupid

6041e29f1f My extent map manager. Sort of like resource maps, but more flexible. 
Understands allocation aligment and boundary restrictions, "specific region"
allocations, and suballocations.  Capable of statically or dynamically
allocating map overhead.

Many thanks to Matthias Drochner for running the code for me, and sending
me bug fixes, optimizations, and suggestions.  Also, many thanks to
Chris Demetriou for his extremely helpful suggestions.

XXX No manual page yet.  One is forthcoming, as soon as I can scare up
the time to write one.  This has been sitting on my plate for quite a
while, and several projects are waiting for it.  Time to move on.

506cefab8c In the sync case of bwrite(), move the accounting earlier so that so that the 
delayed write is logically converted to a sync write, mirroring the async case.
In bdwrite(), move the tape case earlier to avoid needless reassignbuf()s.

1abc77f86d if kmem_malloc() fails while trying to allocate an mbuf cluster, try 
and free some space by calling m_reclaim().  Also, log the "mb_map full"
error message (at most) every 60-seconds.  The old code would log it
once over the lifetime of the system, but that's not a useful diagnostic.
(More useful is the new behaviour, which roughly indicates how often
periods of heavy load occur, without spamming the console and system
logs with messages.)

06c209646e handle the case where kmem_malloc() returns NULL in the 'can wait' case. 
Right now, this code just panic()s (same as kmem_malloc() used to do
before, but different message), but in the future it should be modified
to try to reclaim wasted memory.

f41d0a3d9b in select(), if it's a small number of file descriptors use a 
automatic array rather than an array allocated with alloca().
(This was the only use of alloca() in the kernel, and it wasn't
necessary or consistent with the way other functions in this file
work.)

1e2b610d5a #ifdef __alpha__, call a machine-dependent function with new device 
structure and 'aux', right before ca_attach is called for the
newly-attached device.  This allows the alpha port to do root device
autodetection without modifying every bus and device driver which could
be in the 'boot path.'  In the long run, it may make sense to make
this machine-independent.
