80cc38a1af Fix a partial construction problem that can cause race conditions 
between creation of a file descriptor and close(2) when using kernel
assisted threads.  What we do is stick descriptors in the table, but
mark them as "larval".  This causes essentially everything to treat
it as a non-existent descriptor, except for fdalloc(), which sees a
filled slot so that it won't (incorrectly) allocate it again.  When
a descriptor is fully constructed, the code that has constructed it
marks it as "mature" (which actually clears the "larval" flag), and
things continue to work as normal.

While here, gather all the code that gets a descriptor from the table
into a fd_getfile() function, and call it, rather than having the
same (sometimes incorrect) code copied all over the place.

60a0137d9c Ooops- we need to allocate an array of pointers to scsipi_xfer structures 
isp_maxcmds in length- not an array of scsipi_xfer structures isp_maxcmds
in length.

428f40d685 If there were no processes to list, it meant that our criteria failed 
and didnt match anything.  Dont make our caller think we succeeded.

fe87c9aade When the old PCI address map is in use, disable I/O space. Also disable 
I/O space on PBC revs < B2.

80dfaa3e5a Read the PCI memory space base and the PCI DMA window base from the 
V3 PBC, and use them in the bus mem tag and the bus dma tag on the
P-4032.  This allows us to get much further when PMON has configured
the PBC using the old-style PCI address map.

7ab5601058 Since physical memory below 0x2000 isn't mapped anywhere 
for now, return EFAULT when /dev/mem tries to read it.
Other physical memory not managed by the pmap system is
mapped at the same virtual addresses.  Now that we
understand how VME PTEs are constructed, give mmapping
a VME bus a better chance of working..

4c73c770ce Add MEMSIZE and ETHADDR options, so that they can be set in 
the kernel config file, in case you have a buggy PMON which
doesn't provide the environment variables to the kernel.

15b02e5ba0 Added a function, prom_sd_target, to translate a PROM 
sd unit number into a SCSI target.  Now only set up our
g0 and g4 handlers inside prom_abort(), so we're not
normally running with them.

edad0f956c Under _LKM, now undefine KERNBASE for declaring it. 
Not sure if this is correct, but the real question
is whether 68000 LKMs are even possible.

766dfc9b6f be sure to allocate dirty zeroed pages to cover blocks we allocate 
to resolve a write fault.  fixes PR 13201.
also, be sure to allocate blocks for write faults to holes even if
the page is already in memory.  fixes PR 13189.

4d51fe368b change the meaning of ifnet.if_lastchange to meet RFC1573 ifLastChange. 
follows BSD/OS practice and ucd-snmp code (FreeBSD does it for specific
interfaces only).

was: if_lastchange get updated on every packet transmission/receipt.
now: if_lastchange get updated when IFF_UP is changed.

669f5cc5a5 It's silly to need a parity rebuild after a reconstruction has completed. 
If we've just reconstructed a disk, then the parity is known to
be correct.  (XXX doesn't hold for RAID 6!)

d9d912728f Get rid of externs moved to header files, add event counter for the clock

yet).

3078a3d26d It's pretty questionable to printf a PCI tag, but if we're going to
