previous patch) and this MUST be of that size, otherwise the tables
won't be found.
* powernow_k8.c moved into x86/x86, it should work both i386 and amd64.
* Added more DPRINTFs needed to found the first problem.
* Create "machdep.powernow.frequency" again, I can't remember why I
removed frequency... it should work with estd now.
* Do not try to call k[78]_powernow_init() if cpu is not AMD (thanks
to christos).
And more things I can't remember, but this time it will work in
Athlon 64 cpus and it won't crash in EM64T cpus.
pci_intr_machdep.c. In Xen-3 registers access is done the normal way but
interrupts need custom setup. Proposed on port-amd64, port-i386 and
port-xen a week ago.
kernel by x86 platforms (instead of a simple char *). This way, the code
in, e.g., lookup_bootinfo, is a bit easier to understand.
While here, move the lookup_bootinfo function used in x86 platforms (amd64,
i386 and xen) to a common file (x86/x86_machdep.c), as it was exactly the
same in all of them.
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.
