b7c901eba2 Enable eisa support on alpha.
We need eisa bridge support on some models, which now depends on having
eisa in the kernel.

05d1e23aa7 Split the arch-specific AGP files into the appropriate files.* and do the same
for the agp module, and add agp to the list of modules to compile for alpha.
Add an alpha_mb() to agp_flush_cache for alpha -- it's not correct but may
improve the situation, and it's what linux and NetBSD do.

3bd6561289 NB: This commit does *NOT* make GEOM the default in FreeBSD
NB: But it will enable it in all kernels not having options "NO_GEOM"

Put the GEOM related options into the intended order.

Add "options NO_GEOM" to all kernel configs apart from NOTES.

In some order of controlled fashion, the NO_GEOM options will be
removed, architecture by architecture in the coming days.

There are currently three known issues which may force people to
need the NO_GEOM option:

boot0cfg/fdisk:
        Tries to update the MBR while it is being used to control
        slices.  GEOM does not allow this as a direct operation.

SCSI floppy drives:
        Appearantly the scsi-da driver return "EBUSY" if no media
        is inserted.  This is wrong, it should return ENXIO.

PC98:
        It is unclear if GEOM correctly recognizes all variants of
        PC98 disklabels.  (Help Wanted!  I have neither docs nor HW)

These issues are all being worked.

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.

2ce87d3448 Break out the bus front ends into their own files. Rewrite
sio_pccard_detach to use new siodetach.  Add an extra arg to sioprobe
to tell driver to probe/not probe the device for IRQs.

This incorporates most of Bruce's review material.  I'm at a good
checkpoint, but there will be more to come based on bde's further
reviews.

d75c1b4a90 First commit after a repo copy of isa/sio* -> dev/sio:
Move sio from isa/sio.c to dev/sio/sio.c.  The next step is to break
out the front end attachments, improve support for these parts on
different busses, and maybe, if we're lucky, merging in pc98 support.
It will also be MI and live in conf/files rather than files.*.

2398f0cd1d Hints overhaul:
- Replace some very poorly thought out API hacks that should have been
  fixed a long while ago.
- Provide some much more flexible search functions (resource_find_*())
- Use strings for storage instead of an outgrowth of the rather
  inconvenient temporary ioconf table from config().  We already had a
  fallback to using strings before malloc/vm was running anyway.

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.
