d74ac6819b Compromise for critical*()/cpu_critical*() recommit. Cleanup the interrupt
disablement assumptions in kern_fork.c by adding another API call,
cpu_critical_fork_exit().  Cleanup the td_savecrit field by moving it
from MI to MD.  Temporarily move cpu_critical*() from <arch>/include/cpufunc.h
to <arch>/<arch>/critical.c (stage-2 will clean this up).

Implement interrupt deferral for i386 that allows interrupts to remain
enabled inside critical sections.  This also fixes an IPI interlock bug,
and requires uses of icu_lock to be enclosed in a true interrupt disablement.

This is the stage-1 commit.  Stage-2 will occur after stage-1 has stabilized,
and will move cpu_critical*() into its own header file(s) + other things.
This commit may break non-i386 architectures in trivial ways.  This should
be temporary.

90ce56c287 Add the following functions/macros to support byte order conversions and
device drivers for bus system with other endinesses than the CPU (using
interfaces compatible to NetBSD):

- bwap16() and bswap32(). These have optimized implementations on some
  architectures; for those that don't, there exist generic implementations.
- macros to convert from a certain byte order to host byte order and vice
  versa, using a naming scheme like le16toh(), htole16().
  These are implemented using the bswap functions.
- stream bus space access functions, which do not perform a byte order
  conversion (while the normal access functions would if the bus endianess
  differs from the CPU endianess).

htons(), htonl(), ntohs() and ntohl() are implemented using the new
functions above for kernel usage. None of the above interfaces is currently
exported to user land.

Make use of the new functions in a few places where local implementations
of the same functionality existed.

36412d79b4 - Make the mutex code almost completely machine independent. This greatly
reducues the maintenance load for the mutex code.  The only MD portions
  of the mutex code are in machine/mutex.h now, which include the assembly
  macros for handling mutexes as well as optionally overriding the mutex
  micro-operations.  For example, we use optimized micro-ops on the x86
  platform #ifndef I386_CPU.
- Change the behavior of the SMP_DEBUG kernel option.  In the new code,
  mtx_assert() only depends on INVARIANTS, allowing other kernel developers
  to have working mutex assertiions without having to include all of the
  mutex debugging code.  The SMP_DEBUG kernel option has been renamed to
  MUTEX_DEBUG and now just controls extra mutex debugging code.
- Abolish the ugly mtx_f hack.  Instead, we dynamically allocate
  seperate mtx_debug structures on the fly in mtx_init, except for mutexes
  that are initiated very early in the boot process.   These mutexes
  are declared using a special MUTEX_DECLARE() macro, and use a new
  flag MTX_COLD when calling mtx_init.  This is still somewhat hackish,
  but it is less evil than the mtx_f filler struct, and the mtx struct is
  now the same size with and without mutex debugging code.
- Add some micro-micro-operation macros for doing the actual atomic
  operations on the mutex mtx_lock field to make it easier for other archs
  to override/optimize mutex ops if needed.  These new tiny ops also clean
  up the code in some places by replacing long atomic operation function
  calls that spanned 2-3 lines with a short 1-line macro call.
- Don't call mi_switch() from mtx_enter_hard() when we block while trying
  to obtain a sleep mutex.  Calling mi_switch() would bogusly release
  Giant before switching to the next process.  Instead, inline most of the
  code from mi_switch() in the mtx_enter_hard() function.  Note that when
  we finally kill Giant we can back this out and go back to calling
  mi_switch().

a6bc3edb3b Move the ata/atapi files to the common area. They were the same on all
platforms.

While here, work around a strange quirk in config(8) that I do not yet
understand.  Rearrange which atapi* files have 'optional' vs. 'count'
so that you can have atapifd without atapicd.  The only difference should
be that this works instead of having a link error because atapi-all.o got
left out of the kernel.

0384fff8c5 Major update to the way synchronization is done in the kernel. Highlights
include:

* Mutual exclusion is used instead of spl*().  See mutex(9).  (Note: The
  alpha port is still in transition and currently uses both.)

* Per-CPU idle processes.

* Interrupts are run in their own separate kernel threads and can be
  preempted (i386 only).

21c3015a24 * Completely rewrite the alpha busspace to hide the implementation from
the drivers.
* Remove legacy inx/outx support from chipset and replace with macros
  which call busspace.
* Rework pci config accesses to route through the pcib device instead of
  calling a MD function directly.

With these changes it is possible to cleanly support machines which have
more than one independantly numbered PCI busses. As a bonus, the new
busspace implementation should be measurably faster than the old one.

f71c01cc52 Borrow phk's axe and apply the next stage of config(8)'s evolution.
Use Warner Losh's "hint" driver to decode ascii strings to fill the
resource table at boot time.

config(8) no longer generates an ioconf.c table - ie: the configuration
no longer has to be compiled into the kernel.  You can reconfigure your
isa devices with the likes of this at loader(8) time:
  set hint.ed.0.port=0x320

userconfig will be rewritten to use this style interface one day and will
move to /boot/userconfig.4th or something like that.

It is still possible to statically compile in a set of hints into a kernel
if you do not wish to use loader(8).  See the "hints" directive in GENERIC
as an example.

All device wiring has been moved out of config(8).  There is a set of
helper scripts (see i386/conf/gethints.pl, and the same for alpha and pc98)
that extract the 'at isa? port foo irq bar' from the old files and produces
a hints file.  If you install this file as /boot/device.hints (and update
/boot/defaults/loader.conf - You can do a build/install in sys/boot) then
loader will load it automatically for you.  You can also compile in the
hints directly with:  hints "device.hints"  as well.

There are a few things that I'm not too happy with yet.  Under this scheme,
things like LINT would no longer be useful as "documentation" of settings.
I have renamed this file to 'NOTES' and stored the example hints strings
in it.  However... this is not something that config(8) understands, so
there is a script that extracts the build-specific data from the
documentation file (NOTES) to produce a LINT that can be config'ed and
built.  A stack of man4 pages will need updating. :-/

Also, since there is no longer a difference between 'device' and
'pseudo-device' I collapsed the two together, and the resulting 'device'
takes a 'number of units' for devices that still have it statically
allocated.  eg:  'device fe 4' will compile the fe driver with NFE set
to 4.  You can then set hints for 4 units (0 - 3).  Also note that
'device fe0' will be interpreted as "zero units of 'fe'" which would be
bad, so there is a config warning for this.  This is only needed for
old drivers that still have static limits on numbers of units.
All the statically limited drivers that I could find were marked.

Please exercise EXTREME CAUTION when transitioning!

3f664fc689 A checkpoint of a part of a work-in-progress. Some more cleanups for
config(8).  This commit allows control of the creation of the
#include "foo.h" files.  We now only create them explicitly when needed.
BTW; these are mostly bad because they usually imply static limits on
numbers of units for devices.  eg: struct mysoftc sc[NFOO];
These static limits have Got To Go.

6ab09a6376 Add AlphaServer 2000 (demi-sable), 2100 (sable), and 2100A (lynx) support.
Only PCI and on-board ISA peripherials are supported at this time.

This support has been only lightly tested due to a lack of response to my
call for testers on the freebsd-alpha mailing list.  It works quite well
on the one AS2100 on which it has been tested, but it may not work on
an AS2100A and should therefore be regarded as experimental.
