9510d8b369 The changes to vm_page.c have broken the assumption that mallocing
early will result in memory below 16M so now we need to explicitly use
contigmalloc to get low physical memory.

087d4857e5 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.

226b174bb7 Removed dead code and cleaned up. setconf() now just asks for the
root device name.  The parser for the name is still too simple (it
forces slice = none, partition = 'a').

2633265e24 Made booting with -a work for all configurations. Previously it
only worked for configurations with "swap on generic".

usr.sbin/config/config.y:
- ignore all "swap [on] device ...' specifications except for
  warning about them.  They haven't done anything related to swap
  for almost 4 years, and were previously silently ignored,
  except for "swap on generic" which stopped swap${KERNEL}.c
  from being generated.  Code to support swapping is now deader
  than before.

usr.sbin/config/mkswapconf.c:
- don't generate a dummy setconf() function in swap${KERNEL}.c.

sys/i386/conf/files.i386:
- swapgeneric.c is now standard.  It should be merged into autoconf.c
  so that it doesn't conflict with swap${KERNEL}.c for kernels named
  "generic".

sys/i386/i386/autoconf.c:
- don't call setroot() for mfs roots.  Since setroot() doesn't do anything
  harmful, this was just a waste of time, except possibly for booting with
  -a it may have helped prevent an undesireable call to setconf() by
  finding a bogus rootdev.
- honor -a for ffs roots.  -a now overrides all other ways of specifying
  the root device.  Previously, -r had precedence over -a, and the -a
  handling was usually a no-op.
- don't honor -a for non-ffs roots, since it would currently just get in
  the way of a clean panic.

sys/i386/i386/swapgeneric.c:
- don't declare things that are now always declared in swap${KERNEL}.c.
  Don't decide things that are now decided in autoconf.c.  Code to
  support the "generic" case is now dead instead of useless.

f46a918bc0 Add example for 'makeoptions DEBUG' and some notes. I have not activated
it here since a -g LINT kernel is 100% useless as it won't run and hence
doesn't need debug capabilities (and would just waste disk space :-).

d606317d26 Search bdevsw[] instead of the half-baked builtin table of devices
in the RB_ASKNAME case.  I had thought that I made this change in
rev.1.18, but rev.1.18 only affects obscure subcases of the
RB_DFLTROOT case (subcases where the compiled in default root is
not found in bdevsw[] -- then the root device is set to the first
device in the half-baked table that is also in bdevsw[]).

Removed yet more vestiges of config-time swap configuration.

f9d40bf2df Build the functionality of the wdc_p hack into the ide_pci.c code.
All it did was match a specific device ID and turn on a quirk for
the wdc driver.

Incidently, at line 1462 there is a return that prevents the generic
ide_pci code from trying to look at the device.  I'd be interested
to know if we can take out the return and let the generic code "see" it.
I've left the return in because that's the way it worked before.

(Be sure to rerun config after cvsup or you'll get undefined files!)

7d0299e0a5 Shoot the LKM support in the old wd/wdc/atapi driver set in the head and
perform a cleanup/unifdef sweep over it to tidy things up.  The atapi
code is permanently attached to the wd driver and is always probed.

I will add an extra option bit in the flags to disable an atapi probe on
either the master or slave if needed, if people want this.

Remember, this driver is destined to die some time.  It's possible that
it will loose all atapi support down the track and only be used for
dumb non-ATA disks and all ata/atapi devices will be handled by the new
ata system.

ATAPI, ATAPI_STATIC and CMD640 are no longer options, all are implicit.

Modify targets for debug kernels:  when -g was specified, make will
now build a debug kernel called kernel.debug, and create a stripped
version called kernel at the same time.  The two targets install and
install.debug are otherwise unchanged.

23a589f45b 1. Modify config to issue different code for debugging.
2.  Config complains if you use -g:

    Debugging is enabled by default, there is no ned to specify the -g option

3.  Config warns you if you don't use -s:

    Building kernel with full debugging symbols.  Do
    "config -s BSD" for historic partial symbolic support.
    To install the debugging kernel, do make install.debug

    (BSD was the name of the config file I used; I print out the same
    name).

4.  Modify Makefile.i386, Makefile.alpha, Makefile.pc98 and config to
    work if a kernel name other than 'kernel' is specified.  This is
    not absolutely necessary, but useful, and it was relatively easy.
    I now have a kernel called /crapshit :-)

5.  Modify Makefile.i386, Makefile.alpha, Makefile.pc98 "clean" target
    to remove both the debug and normal kernel.

6.  Modify all to install the stripped kernel by default and the debug
    kernel if you enter "make install.debug".

7.  Update version number of Makefiles and config.

477aac47c6 Add driver support for gigabit ethernet adapters based on the Alteon
Networks Tigon 1 and Tigon 2 chipsets. There are a _lot_ of OEM'ed
gigabit ethernet adapters out there which use the Alteon chipset so
this driver covers a fair amount of hardware. I know that it works with
the Alteon AceNIC, 3Com 3c985 and Netgear GA620, however it should also
work with the DEC/Compaq EtherWORKS 1000, Silicon Graphics Gigabit
ethernet board, NEC Gigabit Ethernet board and maybe even the IBM and
and Sun boards. The Netgear board is the cheapest (~$350US) but still
yields fairly good performance.

Support is provided for jumbo frames with all adapters (just set the
MTU to something larger than 1500 bytes), as well as hardware multicast
filtering and vlan tagging (in conjunction with the vlan support in
-current, which I should merge into -stable soon). There are some hooks
for checksum offload support, but they're turned off for now since
FreeBSD doesn't have an officially sanctioned way to support checksum
offloading (yet).

I have not added the 'device ti0' entry to GENERIC since the driver
with all the firmware compiled in is quite large, and it doesn't really
fit into the category of generic hardware.

94c3a8d12f Two changes to pmap_remove_all:
1. Switch to pmap_TLB_invalidate from invltlb, eliminating a full TLB
flush where a single-page flush suffices.  (Also, this eliminates some
unnecessary IPIs.)

2. Use "loadandclear" to update the pte, eliminating a race condition
on SMPs.

Change #2 should be committed to -STABLE.
