2daa25f3fa Add support for the SIOCGIFHWADDR ioctl, commonly used by
license managers to obtain the host's ethernet address as
a key.

Note that this implementation takes the first hardware address for
the first ethernet interface found, and disregards the interface name
that may be passed in, as linux ethernet devices are all "ethX".

83a98bc0a2 Store the macro values for SWI_TTY_MASK and SWI_NET_MASK in variables to
that lkm's can use them for fiddling the masks without being dependent on
which mode the kernel is compiled in (SMP or UP).  This is particularly
for ppp_tty.c which has some domain crossing between the net and tty
subsystems.  The values are not used in the spl code, they are for
reference only (ie: the compiled code uses immediate values rather than
an indirect 32 bit address and 32 bit data fetch).

72b61693b5 The SWI_NET_MASK and SWI_TTY_MASK handlers are now back adjacent to the
top of the hardware interrupt handlers.  Apparently this is slightly
faster with the bit scanning instruction that looks these up - this set of
changes reverts the original change.

ea8d17534e Bruce's original implementation of the splxxx() routines, but as C code
rather than inlines.  These are compiled with -fomit-frame-pointer and
work out pretty close to the original routines, but it might be a fraction
slower.  The reason for doing this is to prevent the SWI_* and HWI_* values
from being compiled into drivers and lkms etc which is one of the things
that prevents the same lkm from being used on both SMP and UP kernels.

This gives us a lot more scope for experimenting with the splxxx
implementaton for SMP parallelism etc.

ad1b2dcc5c - Use 6x86MX' instead of M2'. Cyrix officially use `6x86MX' for the
CPU code-named `M2'.

- Use the result of cpuid instruction instead of DIR to identify
  6x86MX cpu.  DIR0 and DIR1 are not documented in the data sheet, and
  cpuid instruction is enabled at reset time.

- Add a function, init_6x86MX() to initialize 6x86MX cpu.  It supports
  CPU_SUSP_HLT and CPU_IORT options.  It always sets NC1 (640K - 1M is
  not cached.), and enables L1 cache in write-back mode.

a3186f5a8d Submitted by: Rich Murphey (ages ago) and Gene Stark
Hopefully I've done the proper magic to merge changes between 1.17 and
1.17.2.1 into the main trunk.  Description of those changes follows:

Brought in changes sent to me in late 1995 by Rich Murphey.
I cleaned up a few things and am currently running these under
2.2-970205-GAMMA.

The changes deal with software debouncing apparently necessary on
todays faster hardware, and also some problems with the use of the -Select
line for the TW-523 sync.  This driver allows use of +PaperEnd as an
alternative.

This was done in preparation for massive changes to the SMP INTerrupt
mechanisms.  More fine tuning, such as merging ipl.s into exception.s,
may be appropriate.

cfea775806 Completely replace the PCI bus driver code to make it better reflect
reality. There will be a new call interface, but for now the file
pci_compat.c (which is to be deleted, after all drivers are converted)
provides an emulation of the old PCI bus driver functions. The only
change that might be visible to drivers is, that the type pcici_t
(which had been meant to be just a handle, whose exact definition
should not be relied on), has been converted into a pcicfgregs* .

The Tekram AMD SCSI driver bogusly relied on the definition of pcici_t
and has been converted to just call the PCI drivers functions to access
configuration space register, instead of inventing its own ...

This code is by no means complete, but assumed to be fully operational,
and brings the official code base more in line with my development code.

A new generic device descriptor data type has to be agreed on. The PCI
code will then use that data type to provide new functionality:

1) userconfig support
2) "wired" PCI devices
3) conflicts checking against ISA/EISA
4) maps will depend on the command register enable bits
5) PCI to Anything bridges can be defined as devices,
   and are probed like any "standard" PCI device.

The following features are currently missing, but will be added back,
soon:

1) unknown device probe message
2) suppression of "mirrored" devices caused by ancient, broken chip-sets

This code relies on generic shared interrupt support just commited to
kern_intr.c (plus the modifications of isa.c and isa_device.h).

d1289ee199 Add support for shared interrupts to the kernel. This code is meant
be (eventually) architecture independent. It provides an emulation
of the ISA interrupt registration function register_intr(), but that
function does no longer manipulated the interrupt controller and
interrupt descriptor table, but calls the architecture dependent
function setup_icu() for that purpose.

After the ISA/EISA bus code has been modified to directly call the new
interrupt registartion functions (intr_create() and intr_connect()),
the emulation of register_intr() should be dropped.

The C level interrupt handler function should take a (void*) argument,
and the function pointer type (inthand2_t) should defined in some  other
place than isa_device.h.

This commit is a pre-requisite for the removal of the PCI specific shared
interrupt code.
