in the boot. The cleanup must be done in one of the few ways that
db_numargs() understands, so that early backtraces in ddb don't underrun
the stack. The underruns caused reboots a few years ago when there
was an unmapped page above the stack (trapping to abort the command
doesn't work early).
Cleaned up some nearby code.
curproc was initialized. curproc == NULL was interpreted as matching
the process holding Giant... Just skip mtx_enter() and mtx_exit() in
trap() if (curproc == NULL && cold) (&& cold for safety).
don't take an arg, but swi_generic() is special in order to avoid one
whole conditional branch in the old SWI dispatch code. The new SWI
dispatch code passed it a garbage arg. Bypass swi_generic() and call
swi_dispatcher() directly, like the corresponding alpha code has always
done.
The panic was rare because because it only occurred if more than one
of the {sio,cy,rc} drivers was configured and one was active, and the
cy driver doesn't even compile.
macros that expand to pass filename and line number information. This is
necessary since we're using inline functions instead of macros now.
Add const to the filename pointers passed througout the mtx and witness
code.
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).

Some have dual host->PCI bridges for the same logical pci bus (!), eg:
some of the RCC chipsets. This is a 32/64 bit 33/66MHz and dual pci
voltage motherboard so persumably there are electical or signalling
differences but they are otherwise the same logical bus.
The new PCI probe code however was getting somewhat upset about it and
ended up creating two pci bridges to the same logical bus, which caused
devices on that logical bus to appear and be probed twice.
The ACPI data on this box correctly identifies this stuff, so bring on
ACPI! :-)
This provides support for the Adaptec SCSI RAID controller family,
as well as the DPT SmartRAID V and VI families.
The driver will be maintained by Mark and Adaptec, and any changes
should be referred to the MAINTAINER.
pcib_set_bus() cannot be used on the new child because it is
meant to be used on the *pci* device (it looks at the parent internally)
not the pcib being added. Bite the bullet and use ivars for the bus
number to avoid any doubts about whether the softc is consistant between
probe and attach. This should not break the Alpha code.
- Enable WB cache via CCR2 and CR0.
- Set the need_pre_dma_flush when the CPU_I486_ON_386 option is
defined.

kernel can instigate an orderly shutdown but still determine the form of
that shutdown. Make it possible eg. to cleanly shutdown and power off the
system under ACPI when the power button is pressed.
the build (oops!): replace calls to p_trespass() and PRISON_CHECK()
with p_can(..., {P_CAN_SEE, P_CAN_DEBUG}, NULL)
o Remove volatile usage from procfs_readdir() to remove warnings
o Apply bp's CREATE fix to linprocfs, causing EROFS to be returned on
CREATE calls to procfs_lookup()
o Some further synchronization still needs to occur: only existing
access checks were replaced, to fix the build--the new ones were not
added. I'll do this later today, this is a "fix the build quickly"
commit. This means that, in the interim, some information leakage
can still occur via linprocfs when using jail or kern.ps_showallprocs

- The "Osd*" stuff went away from acpi driver code, use the bus_space
functions directly instead.
- Fix minor english bugs.
acpi_registers_input -> acpi_register_input
acpi_registers_output -> acpi_register_output
- Remove all magic numbers for the sleeping states. We now have
#defines for these.
- NULL is treated the same as the return from aml_get_rootname in
aml_find_from_namespace().

Thanks mike!
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.
