pci_bridge_hook don't actually have any dependancies on PCIBIOS-specific code,
and they can be used to fixup PCI bus numbering in the absence of the BIOS.
To that end, decouple them from PCIBIOS.
and install ${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-disklabel,
${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-fdisk by "reaching over" to
the sources in ${NETBSDSRCDIR}/sbin/{disklabel fdisk}/.
To avoid clashes with a build-host's header files, especially on
*BSD, the host-tools versions of fdisk and disklabel search for
#includes such as disklabel.h, disklabel_acorn.h, disklabel_gpt.h,
and bootinfo.h in a new #includes namespace, nbinclude/. That is,
they #include <nbinclude/sys/disklabel.h>, <nbinclude/machine/disklabel.h>,
<nbinclude/sparc64/disklabel.h>, instead of <sys/disklabel.h> and
such. I have also updated the system headers to #include from
nbinclude/-space when HAVE_NBTOOL_CONFIG_H is #defined.
if there is no pckbc configured. Previously only the latter cuased the
USB keyboard to be used.
This should make it more likely to get the USB keyboard as the console
on legacy free machines using the GENERIC config file.
- distinguish paddr_t and bus_addr_t.
for xen, use bus_addr_t in the sense of machine address.
- move _X86_BUS_DMA_PRIVATE part of bus.h into bus_private.h.
- remove special handling of xen_shm. we can always grab
machine address from pte.
distinction between signalling NaNs and quiet NaNs back into the
machine-dependent headers; treat the implementation of __nanf in the
same spirit.
IEEE 754 leaves the distinction between signalling NaNs and quiet NANs
to the implementation, and unlike our headers used to suggest they're
not identical in the interpretation of the fraction's MSb; in due
course, make those of hppa, mips, sh3, and sh5 reflect reality.
- don't use managed mappings/backing objects for wired memory allocations.
save some resources like pv_entry. also fix (most of) PR/27030.
- simplify kernel memory management API.
- simplify pmap bootstrap of some ports.
- some related cleanups.
to select the maximum segment size for each bus_dmamap_load (up to the maxsegsz
supplied to bus_dmamap_create). dm_maxsegsz is reset to the value supplied to
bus_dmamap_create when the dmamap is unloaded.

This presently consists of the SYSCALL/SYSRET and the EM64T features.
CPUs with the EM64T feature available should be able to run amd64 code.

which indicates that Task Priority Messages might
be disabled. Not relevant for the kernel for now
(related to interrupt distribution on the APIC bus
afaict), but present on one of my boxes.
Being here, also recognise the future "Vanderpool"
extension.
So we better determine the bus number of this parent node.
Now, MPACPI on my Opteron board finally correctly determines its
PCI/AGP busses even without the help of the AMD64 Address Map
support implemented in my local tree.
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.
off, or priority inversion can occur, which can lead to IPI deadlocks.
Leaves interrupts off for a bit longer, sadly, but with no noticeable
effects on the systems I tested on.

add the range to the map, and use it for _bus_dmamap_load_{buffer,mbuf}.
- _bus_dmamap_load_mbuf: in the case of M_EXT_PAGES, deal with vm_pages
directly rather than doing pmap_extract on given kva.
as a side effect, do a segment coalescing and boundary checks for mbufs.
