Multiboot2 kernel support for i386

That implementation works either with BIOS or UEFI bootstrap

This requires the following kernel changes:

Add UEFI boot services and I/O method protoypes
src/sys/arch/x86/include/efi.h 1.8 - 1.9

Fix EFI system table mapping in virtual space
src/sys/arch/x86/x86/efi.c 1.19 - 1.20

Make sure no bioscall is issued when booting off UEFI system
src/sys/arch/i386/i386/machdep.c 1.821 - 1.822
src/sys/arch/i386/pci/piixpcib.c 1.22 - 1.23

And the following bootstrap changes:

Add kernel symbols for multiboot1
src/sys/arch/i386/stand/lib/exec_multiboot1.c 1.2 - 1.3
src/sys/arch/i386/stand/lib/libi386.h 1.45 - 1.47

Fix kernel symbols for multiboot2
src/sys/arch/i386/stand/lib/exec_multiboot2.c 1.2 - 1.3

Added Microsoft Hyper-V support. It ported from OpenBSD and FreeBSD.

graphical console is not work on Gen.2 VM yet. To use the serial console,
enter "consdev com,0x3f8,115200" on efiboot.

This change modifies the mainbus(4) entry point for all x86 sub-archs
in the following way:

i) It provides a unified entry point in
x86/x86/mainbus.c:mainbus_attach()
ii) It carves out the preliminary bus attachment sequence that is
common to all sub-archs into
x86/x86/mainbus.c: x86_cpubus_attach()
iii) It consolidates the remaining pathways as internal callee
functions so that these may be called piecemeal if required. A
special usecase of this is XEN PVHVM which may need to call the
native configure path, the xen configure path, or both.
iv) It moves the driver private data structures from
i386/i386_mainbus.c to an x86/ level one. This allows for other
sub-arch's to do similar, if needed. (They do not at the moment).
v) For dom0 kernels, it enables 'acpi0 at mainbus?' and
'acpi0 at hypervisorbus'. This serves two purposes:
a) To demonstrate the possibility of dynamic configuration tree
traversal ordering changes.
b) To allow for the common acpi_check(self, "acpibus") call in
x86/mainbus.c to not barf when it is called from the dom0 attach
path. We allow for the acpi0 device to be a child of mainbus with
the changes to amd64/conf/XEN3_DOM0 and i386/conf/XEN3PAE_DOM0
without actually probing further in the code. This path will later
be pursued in a PVHVM boot codepath.

There should be no operative changes with this change. If there are,
please complain loudly.

Move mainbus(4) driver files in various x86 sub-archs to name prefixed
versions. This allows us to further modularise them by unifying common
bus probe code in x86/x86/mainbus.c to be introduced next.

This commit has no functional changes. It is done for ease of
visibility of newer diffs in the queue.

KASLR is in files.kern

Retire NDIS. It appears that it has never worked, after 13 years it was
still marked as "experimental", and nowadays it may be one more obstacle
to MPification of the network stack.

Discussed on tech-net@.

Remove the X86PMC code I had written, replaced by tprof. Many defines
become unused in specialreg.h, so remove them. We don't want to add
defines all the time, there are countless PMCs on many generations, and
it's better to just inline the event/unit values.

Remove ipkdb from i386. Also remove unused references in amd64.

I already talked about doing that six months ago on port-i386@. Back then
it was as general cleanup, but now, with SVS etc, we do actually have
good reasons for simplifying the entry points.

Remove support for vm86 on i386. It is bug-friendly, and there is no point
in having kernel support for this: the instruction set of the CPU is small,
and it can easily be emulated in userland entirely. There are also several
assumptions in the code that are not respected, and the slightest confusion
in the trap frame can lead to ring0 exploits.

vm86 has received zero maintenance. As far as I can tell, it was added
20 years ago in order to make doscmd work. But doscmd has not been
maintained either, and was removed from pkgsrc in 2011. dosbox can be used
instead: it does not require kernel support, and will produce better
results than our flimsy implementation.

Pass 1. (many pieces still in the tree)

Remove compat_ibcs2 from i386. After a discussion on port-vax, it turns
out that compat_ibcs2 does not implement the iBCS2 standard - which is
x86-specific - but rather SVR3. Our real iBCS2 implementation was a
mixture of compat_ibcs2 and compat_svr4, and was only partial. Keeping
support for this in i386 is totally irrelevant today. I also asked on
port-i386 but didn't wait long.

The main issue is that compat_ibcs2 should have been called compat_svr3.
But CVS does not support renaming files, and moving things around is both
painful and tiring, even more so when no one seems to be interested in
doing this work or in the feature at all. For now compat_ibcs2 is available
on Vax and will stay, until someone (not me) cleans it up.

Move arch/i386/i386/freebsd_* into compat/freebsd/. COMPAT_FREEBSD is
i386-specific.

Don't include files.svr4 and files.svr4_32.

Drop support for svr4 on i386. This feature is not maintained, not
reliable, and of a limited use case. Most svr4 applications got time to be
ported to linux, and we do have a functional, maintained linux emulation.

Reduces the number of entry points into the kernel, the number of
places that need special care (cpu context).

Note that compat_svr4 is still available on sparc.

Remove the remaining parts of compat_oldboot.

Add support for hardware assisted watchpoints/breakpoints API in ptrace(2)

Add new ptrace(2) calls:
- PT_COUNT_WATCHPOINTS - count the number of available hardware watchpoints
- PT_READ_WATCHPOINT - read struct ptrace_watchpoint from the kernel state
- PT_WRITE_WATCHPOINT - write new struct ptrace_watchpoint state, this
includes enabling and disabling watchpoints

The ptrace_watchpoint structure contains MI and MD parts:

typedef struct ptrace_watchpoint {
int pw_index; /* HW Watchpoint ID (count from 0) */
lwpid_t pw_lwpid; /* LWP described */
struct mdpw pw_md; /* MD fields */
} ptrace_watchpoint_t;

For example amd64 defines MD as follows:
struct mdpw {
void *md_address;
int md_condition;
int md_length;
};

These calls are protected with the __HAVE_PTRACE_WATCHPOINTS guard.

Tested on amd64, initial support added for i386 and XEN.

Torn down KSTACK_CHECK_DR0, i386-only feature to detect stack overflow

This feature was intended to detect stack overflow with CPU Debug Registers
(x86). It was never ported to other ports, neither amd64 and should be
adapted for SMP...

Currently there might be better ways to detect stack overflows like page
mapping protection. Since the number of Debug Registers is restricted
(4 on x86), torn it down completely.

This interface introduced helper functions for Debug Registers, they will
be replaced with the new <x86/dbregs.h> interface.

KSTACK_CHECK_DR0 was disabled by default and won't affect ordinary users.

Change i386 to use x86/fpu.c instead of i386/isa/npx.c
This changes the trap10 and trap13 code to call directly into fpu.c,
removing all the code for T_ARITHTRAP, T_XMM and T_FPUNDA from i386/trap.c
Not all of the code thate appeared to handle fpu traps was ever called!
Most of the changes just replace the include of machine/npx.h with x86/fpu.h
(or remove it entirely).

Convert the amd64 build to use x86/cpu_extended_state.h so that the fpu
definitions match those of i386.
Mostly just structure and field renames, in addition:
1) process_xmm_to_s87() and process_s87_to_xmm() moved into
x86/convert_xmm_s87.c so they can be used by amd64's netbsd32 code.
2) The linux signal code simplified to use a structure copy for ths fxsave
data - it matches the hardware definition and won't change.

Remove support for 'external' floating point units and the MS-DOS
compatible method of handling floating point exceptions.
Make kernel support for teh fpu non-optional (486SX should still work).
Only 386 cpus support external fpu, and i386 support was removed years ago.
This means that the npx code no longer uses port 0xf0 or interupt 13.
All the "npx at isa" lines go from the configs, arch/i386/isa/npx.c
is now mandatory for all i386 kernels.
I've renamed npxinit() to fpuinit() and npxinit_cpu() to fpuinit_cpu()
to match the very similar amd64 functions.
The fpu of the boot cpu is now initialised by a direct call from
cpu_configure(), this enables FP emulation for a 486SX.
(for amd64 the cr0 values are set in locore.S and similar).
This fixes a long-standing bug in linux_setregs() - which did not
save the fpu regsiters if they were active.
I've test booted a single cpu i386 kernel (using anita).
amd64 builds - none of teh changes should affect it.
The i386 XEN kernels build, but I'm not sure where they set cr0, and
it might have got lost!

Remove the obvious parts of i386 Advanced power management 'apm' support.
This is the code that predates ACPI, and might once have been able to

It hasn't been compiled for ages (it isn't it i386/ALL or any other
standard kernel) and hasn't worked for even longer.
The APM specification was made obsolete by ACPI before it was widely

Since files.wscons et al. are included by ~all ports anyway, include
them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
should be easy to fix.

Refactor in_cksum/in4_cksum/in6_cksum implementations:
- All three functions are included in the kernel by default.
They call a backend function cpu_in_cksum after possibly
computing the checksum of the pseudo header.
- cpu_in_cksum is the core to implement the one-complement sum.
The default implementation is moderate fast on most platforms
and provides a 32bit accumulator with 16bit addends for L32 platforms
and a 64bit accumulator with 32bit addends for L64 platforms.
It handles edge cases like very large mbuf chains (could happen with
native IPv6 in the future) and provides a good base for new native
implementations.
- Modify i386 and amd64 assembly to use the new interface.

This disables the MD implementations on !x86 until the conversion is
done. For Alpha, the portable version is faster.

Attach two new devices to the AMD Elan SC520 System Controller,
elansc(4).

elanpex(4) is for PCI exception reporting. I've already found some
kernel bugs by reading the exceptions reported. Beware that it
will spam the console a lot while the kernel and pcictl(8) probe
non-existing addresses in PCI configuration space.

elanpar(4) protects the kernel text from writes by the CPU and by
PCI bus masters. As you might guess, this is not compatible with
setting breakpoints using a debugger; detach the device using
'drvctl -d elanpar0' before you try to set breakpoints. In the
future, I hope to extend elanpar(4) to provide general-purpose RAM
write-protection.

clean up how cpus and ioapics are attached at the mainbus:
Seperate "cpubus" and "ioapicbus" -- while they share a common "address
space" (the apic id), the kernel doesn't use this fact. There are different
data passed to cpus and apics, which caused some ugly polymorphism. This
also saves the special "submatch" functions needed to distingush cpus
and ioapics for autoconf. (And it makes that "apid" locators wired
in the kernel configuration are honored now; this allows one to dumb down
an mp box to singleprocessor by userconfig.)

Mark MULTIBOOT_SYMTAB_SPACE obsolete instead of silently removing it.
Per cube@'s suggestion.

Remove the usage of Multiboot's "a.out kludge" to tell the boot loader to
reserve some more space for the BSS section than the binary says. This
trick was used to leave room after the kernel's image to copy the symbol
table following the format required by ksyms_init. (It was also used to
workaround a bug in the physical address fields of the binary, but this has
been long fixed.) Yes, the MULTIBOOT_SYMTAB_SPACE option goes away; yay!

Instead, copy the required data after the kernel in a way that avoids having
to reserve space and use the new ksyms_init_explicit function to avoid the
need to construct a minimal ELF image.

Fixes ksyms when using an "unpatched" GRUB (one that does not contain the
fix to honour the "a.out kludge" for ELF images, even when present) -- i.e.
ddb and lkms. As a side effect, the new code is much clearer to read and
digest.

A number of minor changes for NDIS. (OK'd by phil)

1. Removed the makeoptions line from arch/i386/conf/GENERIC. Now
ndis_driver_data.h is simply copied into the kernel build directory instead
of editing the config file to specify its location.

2. Uncommented lines in files.i386 and files.pci related to NDIS. NDIS will
not be compiled into the kernel unless the two lines are uncommented from
GENERIC (I checked using nm), so there is no reason for this to be commented
out.

3. Added ndiscvt to usr.sbin/Makefile.

Convert existing ath users to new Makefile, except for amd64, which needs
the rules due to needing to conditionally postprocess the HAL object file.

Macppc needs a a non-ELF HAL (EABI) object, so take care of that by default
in the atheros include file.

Updated to the latest NDIS code. I added commented out lines in the files
arch/i386/conf/GENERIC, arch/i386/conf/files.i386 and dev/pci/files.pci which
can simply be uncommented to compile NDIS into the kernel. I'll write some
documentation on this soon.

Note that NDIS is still somewhat experimental. It is currently tested and
functions relatively well on on two cards:
1. Dell (Broadcom) TrueMobile 1400 Dual Band WLAN Mini-PCI
2. Intel EtherExpress Pro/100

Backout part of previous since it breaks kernel build and not described

It turns out that pci_addr_fixup() doesn't require PCIBIOS either. Decouple,
run it from mainbus_attach().

Rework the configuration scheme for PCI fixups:

* bus enumeration fixups are not PCIBIOS-specific, interrupt fixups are done
by both PCIBIOS and ACPI. The redundancy is very redundant. Therefore,
rename PCIBIOS_*_FIXUP to PCI_*_FIXUP, use PCI_INTR_FIXUP in place of
ACPI_PCI_FIXUP, and change code refences to match.

* move the fixup defines from opt_pcibios.h to opt_pcifixup.h to reflect
the above.

* fix up the PCI bus numbering in mainbus_attach(), right after we detect the
configuration mode. This probably renders the fixup in pcibios.c
redundant -- but it should be harmless.

These changes make cardbus work in ACPI-only machines, when PCI_BUS_FIXUP
and PCI_INTR_FIXUP are defined.

Move linux_trap.c from sys/arch/i386/i386 to sys/arch/x86/x86, and share

do not include "compat/aout/files.aout", COMPAT_AOUT is soon to be removed

remove the (superfluous) definition of "cpu" as an interface attribute

Phase out the use of a string as first "attach args" member to control
which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.

Add an option to allow any user to write to machdep.est.frequency.target,
which is very handy on a laptop to control EST through another program that
you don't necessarily want to run as root (in my case, gkrellm).

Integrate support for Enhanced SpeedStep Technology (est) that
Michael Eriksson posted to port-i386 on 20031102, with various
modifications by me to work in the new sysctl(9) framework.

The code is enabled with 'options ENHANCED_SPEEDSTEP', and if
the CPU supports EST the following sysctl(8) nodes appear
(with the values that a Dell Inspiron 8600 + WUXGA with a
1.4GHz Pentium M CPU supports):
machdep.est.cpu_brand = Intel(R) Pentium(R) M processor 1400MHz
machdep.est.frequency.target = 1400
machdep.est.frequency.current = 1400
machdep.est.frequency.available = 1400 1200 1000 800 600

If EST support isn't available, the "machdep.est" sysctl sub-MIB
is not created.

Once we have a more general "CPU frequency" control API we can
migrate this code to using that.

Thanks to Michael Erikkson for providing this code!

Abstract the interface between pckbc(4), and the pckbd(4) and pms(4)
drivers that attach to it. This allows for other host interface chips
that use the same keyboards and mice, such as the ones in the ARM
IOMD20, ARM7500, and SA-1111. The PC-compatible driver is still
called pckbc(4), and the new abstraction layer is "pckbport", so the
child devices have moved from sys/dev/pckbc to sys/dev/pckbport, which
also contains some code shared between all host controllers. To avoid
incompatibility, pckbdreg.h is still installed in
/usr/include/dev/pckbc.

In theory, this shouldn't cause any behavioural changes in the drivers
concerned. Thy just use rather more function pointers than before. Tested
on i386 and (with a new host driver) acorn32. Compiled on several other
affected architectures.

Add a new MI attribute, pckbc_machdep_cnattach, and change pckbc_cnattach()
to only call pckbc_machdep_cnattach() if this is present. This allows
pckbc_machdep_cnattach() to be omitted entirely on most ports, where it only
returns ENXIO anyway.

The devices with this attribute at the moment are pc(4) on i386 and bebox, and
pckbc on sparc, where pckbc_machdep_cnattach() mysteriously returns 0 rather
than ENXIO.

cleanup old lpt(4) attachment, and glue ppbus in so that they can coexist:

configured or if there is alternative platform lpt (like for pc532)
* g/c MD lpt definitions and custom puc/upc attachments,

device lpt definition from dev/isa/files.isa
* add ppbus parport attribute, atppc device attachments, adjust plip and lpt
glue

We can't use bf_cbc.S if I386_CPU is defined; the 80386 doesn't have
bswapl, and bf_cbc.S uses it. Unfortunately, this means that GENERIC
will no longer use the asm code -- though it will still use the asm
for the basic Blowfish transform. This won't slow down the KAME IPsec
(since it rolls its own CBC) but may slow down fast-ipsec in kernels
that have I386_CPU defined.

New interrupt code. The basic idea behind it is to hide the differences
in interrupt controllers in struct pic, and try to keep as much
common code as possible. At the lowest (asm) level, this is done
with CPP macros.

The main structure is now struct intrsource, describing an established
interrupt line, of any kind (soft/hard local apic/legacy apic/IO apic).
For quick masking, there may be a maximum of 32 sources per CPU.
Sources can be assigned to any CPU in the MP case, though currently they
all go to the boot CPU.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

boost maximum MAXUSERS to 128

Add asm versions of blowfish and des transforms for i386.

This also involved updating the in-kernel DES functions to correspond
to the versions in our in-tree OpenSSL, because the des_SPtrans table
has changed; the asm code will not work with the old permutation table!

C and i386 asm code for the DES, 3DES, and Blowfish CBC modes is also
included; it is not currently built as the ESP processing in esp_core.c
splits the CBC operation and the cipher transform apart. Hopefully that
will be fixed as there is a substantial performance improvement to be had
from doing so. It will remain necessary to use the C version of the
Blowfish CBC function on some i386 machines, however, as the asm version
uses bswapl, which ony 486 and later processors have. The DES CBC code
doesn't have this problem.

Finally, change esp_core.c to use the ecb3_encrypt function instead of
calling ecb_encrypt three times; this improves performance a bit, in
particular in the asm case.

This is the first check-in of CardBus driver. CardBus driver contains
CardBus bus stub, YENTA PCI-CardBus bridge (cbb), 3Com 3C575TX driver
(ex) and Intel fxp driver.

TODO:
o Conform to the KNF more strictly.
o Be unified with pcmcia code as much as possible.
o Add more drivers for CardBus card, such as APA-1480 or USB card.

Introduce new option APM_NO_POWER_PRINT which disables printing
power status on the console (if apmd is absent).
Some systems generate APM_POWER_CHANGE events too frequently (more then
once per minute), and printing the status makes single user operations
rather difficult.

oops - there got something into the last commit which shouldn't

add a flag to control use of APMv1.2

- compat_aout requires compat_13_machdep.c for definition of sigreturn.

PMAP_NEW is no longer optional on the i386; the old pmap's page table
allocation strategy no longer works at all. Move pmap.new.* to pmap.*.

To read the revision history of PMAP_NEW up until this merge, use cvs
rlog of the old pmap.new.* files.

Only declare block major numbers for devices which can be the root device.

update for pms->opms renaming

Fix up support for PCI attachments of pcic devices on i386 in general,
and the Cirrus Logic CL-PD6729 in particular.

From danw@mit.edu in PR port-i386/6436.

Export the `pcmciabus' attribute on the `pcic' controller.

defopt the APM options.

Add a CPURESET_DELAY options which specifies the delay (in milliseconds)
between the "rebooting" message and the hardware reset. If set to 0, the call
to delay() is disabled. Default is 2s.

Merge bouyer-ide

The linux compat i386 "files" file moved into arch/

linux_machdep.c has been moved. It is now included from compat/linux/i386/files.linux_i386.

Fix thinko in previous.

Include db_dbgregs.s for ddb

Don't include files.isapnp here.

branches: 1.116.2;
Add USB support. Supported so far:
* UHCI and OHCI host controllers on PCI
* Hubs
* HID devices withe special drivers for mouse and keyboard
* Printers

add device declarations for 'puc'-related devices. Add lpt attaching
to puc to the files file, because it can't go in files.pci (see comments
here or there).

Add ISA Plug and Play attachment for PCIC PCMCIA controller (pcic* at isapnp?).
Slightly modify ISA attachment to let the two share code.

branches: 1.113.2;
add a device node for "sysbeep at pcppi"

VGA and spkr are now MI.

allow use of new wscons code:
-rename the "pckbd" internal attribute to pckbcport, it conflicts with the
real pckbd device in dev/pckbc
-add attachments of pccons and pms to the new mi keyboard controller
driver (more or less for testing)
-include the new "files.wscons" and "files.pckbc"
-add declarations for VGA - must be done here for now to avoid conflicts
with alpha's private VGA driver

add file declarations for MD pciide file.
add (temporary) device/file declarations for the MI PCI IDE controller
driver. These are present here until the wdc declaration mess is
resolved, because until then they need to go into MD files files in
places where they play nice with the wdc declaration.

Nuke random.s.

Remove "class" declarations, and add "devclass" declarations where
appropriate. Fix several inconsistencies between device class and
attributes. Mostly from Chris Demetriou.

Add pceb at pci and {eisa,isa} at pceb attachments.

add the i386 MD portions for UVM.

Generate dependenices on the XSERVER option.

Generate dependencies on the DUMMY_NOPS option.

Generate dependencies on the USER_LDT option.

Generate dependencies on the MATH_EMULATE option.

Generate dependencies on the VM86 option.

Generate dependencies on the CPU type options (I386_CPU, I486_CPU, ...)

Oops, something snuck in there that shouldn't have...

Get include file paths correct.

Shuffle wd/wdc driver files around (via repository copies). wdc
now lives in dev/ic, wd now lives in dev/ata. there's now a 'ata'
interface attribute defined in conf/files, but wdc can't go there
yet because some ports still use private versions based on the old
ISA version.

Update for changes to config.

Revert I486_PCI_MEM_ENABLED change, it caused too many problems.

defopt I486_PCI_MEM_ENABLED

Defopt PCIC_ISA_ALLOC_IOBASE, PCIC_ISA_ALLOC_IOSIZE, and
PCIC_ISA_INTR_ALLOC_MASK.

Update for new location of i82365.c

Add mii.

Pull marc-pcmcia branch down from trunk.

add bioscall attribute and bioscall.s/apmcall.s files

Add an ibcs2_setregs().

Merge scsipi branch in the mainline. This add support for ATAPI devices
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.

Remove unneeded dev/cninit.c.

Oops; remove something that shouldn't be here.

Translate in_cksum() to assembler, and speed it up a bit.

Make the MI LANCE driver standalone, and use cfattach to resolve
naming conflicts between bus attachments on ports that can have
multiple instances of the LANCE.

there's now a eisa_machdep.c which must be included when including
EISA support.

add joystick driver from Matthieu Herrb (pr #2267)

modify these to provide a new, better-specified PCI interface
(soon to be documented on mailing lists; eventually in section 9 manual
pages), most importantly:
(1) support interrupt pin swizzling on non-i386 systems with
PCI-PCI bridges (per PPB spec; done, but meaningless, on i386).
(2) provide pci_{io,mem}_find(), to determine what I/O or memory
space is described by a given PCI configuration space
mapping register.
(3) provide pci_intr_map(), pci_intr_string(), and
pci_intr_{,dis}establish() to manipulate and print info about
PCI interrupts.
(4) deprecate the pci_map_* functions, and provide them only
as compatibility interfaces (in pci_compat.c) which will
eventually go away, implemented as wrappers around
the functions described above.
(5) make pci functions take as an argument a machine-dependent
cookie, to allow more flexibility in implementation.

Added support for rd (ramdisk) pseudodevice, needed for new install system.

attach the speaker device to pckbd (it falls in the I/O range of the
keyboard/console device cluster)

New device attachment scheme:

- split softc size and match/attach out from cfdriver into
a new struct cfattach.

- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.

Change the PS/2 mouse driver to be a child of the "pckbd" attribute,
which represents the "keyboard controller". Give "pc" and "vt" drivers
the "pckbd" attribute. In pcattach() (pccons and pcvt), attach children
of the keyboard controller.

Attach isa, eisa, and pci to mainbus now, rather than root. The i386
now has a single device tree (rather than a forest). Also, attach
EISA only if it's present, and attach in order: PCI, EISA, ISA (most
specific to least specific).

update for adjustments to ISA and PCI 'files' files

Trim some comments relating to EISA configuration that are no longer relevant.

Move the speaker driver to 'new' config. (Closes PR 1361, from Rafal Boni)

VM86 support, by John Kohl, touched up a bit by me.

Various changes from John Kohl and me:
Map kernel stacks only at unique addresses.
Use one TSS per process.
Add sysarch calls for modifying IOPL and the I/O permission bitmap.
Add a compacting GDT entry allocator, for TSS and LDT selectors.
Enable modifying %fs and %gs with PT_SETREGS.
Sanitize various bits of code.

Minor change.
