This mandatory function will get invoked in pci_probe_device(), and allows
a pci host driver to alter the pci_attach_args passed to a device when
attaching.
This function will also, if returning non-zero, cause the device to be
skipped completely during all the phases of the PCI device discovery
(i.e. ressource enumeration, ressource assignment, and actual attachment).
This particular feature is experimental and might be reverted in the future
(or the scope narrowed to device attachment only).
A dummy #define pci_probe_device_hook() 0 is added to all platforms except
sgi, where real functions (currently only returning 0) are added; real meat
will be added shortly.
Discussed at s2k11, no objection from the usual suspects.

all these
arch's LABELSECTOR == DOS_LABELSECTOR == 1, and LABELOFFSET == 0. Thus, to quote bob,
"This is a no-op". Makes the expression used when writing label the same as the one
used in readdoslabel().

via readdoslabel(), tweak writedisklabel() to write disklabels at
the same place readdoslabel() reads them from. Irregardless of the
physical disk sector size. As is done in i386/amd64 already.
No change in behaviour for the 'normal' 512-byte sector case.

i386. Stop abusing it on other archs for controling a shutdown by
pressing the soft power button:
* Add a MI sysctl hw.allowpowerdown; if set to 1 (the default) it
allows a power button shutdown.
* Make acpi(4)/acpibtn(4) honor hw.allowpowerdown.
* Switch the various power button intercepts on landisk, sgi, sparc64
and zaurus over to hw.allowpowerdown.
* Garbage collect the machdep.kbdreset sysctl on all archs other than
amd64 and i386.

The new world order of pmemrange makes this data completely redundant
(being dealt with by the pmemrange constraints instead). Remove all code
that messes with the freelist.
While touching every caller of uvm_page_physload() anyway, add the flags
argument to all callers (all but one is 0 and that one already used
PHYSLOAD_DEVICE) and remove the macro magic to allow callers to continue
without it.
Should shrink the code a bit, as well.
matthew@ pointed out some mistakes i'd made.

function, and let attachment code calls this rather than malloc(9).
This prevents re-initialization of the queue in shared queue chipsets.
Also, add wdc_free_queue() as a complementary function.
Earlier version (without wdc_free_queue()) tested by sthen@ and Amit
Kulkarni on various pciide(4) chips.

(interrupt was not for me), 1 (positive interrupt was for me), or -1
(i am not sure...). We have continued with this practice in as many
drivers as possible, throughout the tree.
This makes some of the architectures use that information in their
interrupt handler calling code -- if 1 is returned (and we know
this specific machine does not have edge-shared interrupts), we
finish servicing other possible handlers on the same pin. If the
interrupt pin remains asserted (from a different device), we will
end up back in the interrupt servicing code of course... but this is
cheaper than calling all the chained interrupts on a pin.
This does of course count on shared level interrupts being properly
sorted by IPL.
There have been some concerns about starvation of drivers which
incorrectly return 1. Those drivers should be hunted down so that
they return -1.
(other architectures will follow)

are past. Use CLR() and SET() to modify necessary flags while leaving
the flags used by the buffer cache in peace.
Should make bufcache code much less confused about the state of the
bufs used in reading/writing disklabels. Other such flag abuses no
doubt await a visit.

using the -MD option to cc, with -MP, -MT, and -MF where needed, converting
"make depend" to a no-op. This increases parallelism for those using "make -j"
and keeps the dependencies up to date with each compilation automatically.
sparc and vax users will need to rebuild gcc with support for the
-M[PTF] options before config'ing with this diff.

mentioning the error strings, and make their callers check the return value
against zero, not NULL.

do 32-bit block spanning. If later on we get some that can/should do
64-bit, that can be done now using daddr64_t (but of course, we are taking
this step to finalize the daddr_t 64-bit conversion).

having it linked last is bad (on at least i386 and amd64) because the lapic
is mapped over the start of the data segment -- savecore(8) then reads the
version string for a fixed buffer space, and reads into the lapic area
causing unintended side-effects (at least on Intel X5570 and X5680)
