4689d219ff Fixed gross breakage in previous commit. The malloc sizes for the
temporary file names were uninitialized if TMPDIR was set and 1 too
small otherwise.

Fixed style bugs in previous commit.

Fixed missing checks for malloc failure in previous commit.

Report malloc failure consistently, at least in temp.c.

7934b2cd38 Don't pretend to support ix86's with 16-bit ints by using longs just
to ensure 32-bit variables.  Doing so broke i386's with 64-bit longs.

This also fixes printf format errors.

Didn't fix rotted bits (including not passing dosdev to the kernel and
serious out of dateness when initially committed).

c9a5e21100 Attempt to work around the page fault in tulip_txput(). I've been running
this myself for ages, but wasn't able to get any feedback from the people
that I sent it to for testing.

Guy Helmer <ghelmer@scl.ameslab.gov> has given it a shot (before getting on
a plane, thanks!) and it appears to stop his reproducable page fault panic
in the testing he was able to do.

51f3fe7ab2 Use Mike Smith's linker module search path code.
Implement preloading in a fairly MI way, assuming the information is
prepared.
DDB interface helpers..  Provide some support for db_kld.c so that we
don't have to export too much detail.
Debugging and cosmetic nits left in from development..
The other half of the containing file hack so modules can associate
themselves with their "file".

f3b0d44290 Keep track of the containing file for modules. This is a bit of a hack,
but I can't think of another (relatively) easy way of getting the info
since the boot-time initialization is not done immediately after "loading".
XXX module_register() gained an extra arg.  This might break the alpha
compile, if so, just add a zero to get the old behavior.

e4f1a52f7a Updates for alignment rounding. XXX this is highly machine dependent and
should probably be moved to i386/i386/link_machdep.c (and the same for the
alpha).
Implement "deleting" a preloaded module by destroying it's tags. This is a
hack.  We cannot reuse the data, it's been destroyed by relocation,
statically initialized variables have been modified, etc.  Note that to
reclaim the load space is going to be more machine-dependent work.
Implement a relocate hook for machdep.c to call so that the physical
addresses get converted to the equivalent KVM addresses.

de78ca7e63 Fully implement KLD and preloading.
- seperate unload for preloaded linker objects.
- Don't build a kernel object if running as an a.out kernel.
- extract the real kernel name rather than hardwiring "kernel" for kldstat.
  (sysctl kern.bootfile getst the full name via bootinfo)
- use real addresses on the kernel "module" rather than fictitious ones.
- preloaded module support
- search module path for file modules.
- symbols are checked to see if they are in the right containing file
  before using their indexes into string tables.  This is to help ddb
  since it only supplies a pointer to an opaque symbol and there is no
  telling which file/object/module/whatever it came from.

adbb7dbee6 Updates for KLD backends.
- symbol_values checks that the symbol is indeed belonging to the
   correct symbol and string table pairs before looking up. (since there
   could be many pairs, and KLD/DDB need to find out).
 - different ops for files versus preload modules - the unload mechanism
   is different.  (a preloaded module has to be deleted on unload since
   the in-core image is tainted by relocation and variables used)
 - Do not build an a.out kernel module if we're running on an elf
   kernel. :-)  Note that it should theoretically be possible to
   mix a.out and elf KLD modules providing -mno-underscores was used
   to compile it, or some other symbol conversion takes place.
 - Support preload modules (even though /boot/loader doesn't yet)
 - Search the module path when loading files.

94e9d7c12d Implement merging SYSINIT's from preloaded KLD modules. This means we
check off SYSINIT entries as they are run, and when more arrive, we re-sort
and restart (skipping the already-run entries).
This can *only* be done after KMEM (and malloc) is up and running - this is
fine because KLD is the only consumer of this and it's done after that.
The nice thing about this is that the SYSINIT's within preloaded KLD modules
are executed in their natural order.  It should be possible to register
devices for the probes which follow, etc.  (soon.. several key things
prevent this, such as use of linker sets for things like pci devices).

df9e84e0c0 Relocate the preload module info from machdep specifically rather than
trying to do it in locore.  We also walk through the module table
and relocate any MODINFO_ADDR pointers so that they become KVM relative
rather than physical addresses.  This means that hacks for adding
0xf0000000 in places like MFS go away.

c6b72a39e9 Call some helper routines to be supplied by kern_linker.c in order to
get to all the symbol tables for all modules, not just the core kernel
symbol table.  Yes, DDB can see KLD module symbols with this, both by
lookup and in tracebacks.  No more references to _end from tracebacks
within an LKM. :-)

286896fe56 At the moment, the alpha tentatively uses the ddb elf code rather than KLD,
because the alpha boot loader hasn't been converted yet, and because
it needs the full symbol tables with local symbols in order to make sense
of stack tracebacks.  KLD will implement this (using full sybmol table
rather than the globals only) shortly.

ea4170d0f6 We don't compile this on an elf kernel (and explicitly not on alpha in

7deb2dabef Attempt to at least align MODINFO_* blocks. IMHO, decoding this stuff
should be MD code since one day we'll have to recover pages from deleted
preload data.  MI code can't be expected to know how to deal with pmap
internals, assuming it gets done via pmap that is. :-)
