OOP speak, you would mark these as 'protected' members. Specifically:
- Make the pcib_softc struct public so it can be used by subclasses.
- Make pcib_{read,write}_ivar(), pcib_alloc_resource(), pcib_maxslots(),
and pcib_{read,write}_config() globals that can be used by subclasses.
- Make the pcib devclass a global variable.
- Move most of the pcib_attach() function into a global
pcib_attach_common() function that can be called by the attach routines
of subclasses.
Tested on: i386, alpha, sparc64, ia64
- Make the pci devclass a global variable.
- Add child devices in pci_attach() instead of pci_probe(). Change
pci_probe() to just check for a valid bus number from the associated
bridge and return -1000 if successful. This allows subclasses of the
PCI bus driver to override the generic driver.
- Move the code to load the vendor data into its own public function.
Really though, doing this at attach is just plain wrong. This should
really be done in the module load routine instead. As a side effect,
the 'busno' variable in pci_attach() is now no longer static (minor
bug that was harmless so far.)
- Change pci_add_children() to take an extra argument that is the size of
the device info structure passed to pci_read_device() and make it public
so subclasses of the PCI bus can call it in their attach routines.
- Move the bits to attach a probed PCI child to a PCI bus into a global
pci_add_child() function. This will allow subclasses that can detect
a PCI device not found in the normal PCI probe to add those devices in
their own attach routine. (I have seen this in the ACPI tree on my
laptop for example.) As a side effect, change the static function
pci_add_resources() to get the busno, slot, and func from the passed
in dinfo structure instead of requiring them as function arguments.
Tested on: i386, alpha, ia64, sparc64
LNK device (interrupt source provider sort of) is present before using it,
but the code actually tested the status (_STA) of the PCI bridge device
doing the routing, not the actual LNK device. Fix it to check the status
of the LNK device.
Change _BSD_CLK_TCK_ and _BSD_CLOCKS_PER_SEC_ to match stathz. This
should result in bug for bug compatibility in staticly linked
programs and dynamicly linked programs should see an immediate
correction.
firewall logging on and off when at elevated securelevel(8). It would
be nice to be able to only lock these at securelevel >= 3, like rules
are, but there is no such functionality at present. I don't see reason
to be adding features to securelevel(8) with MAC being merged into 5.0.

pmap_zero_page() and pmap_zero_page_area() were modified to accept
a struct vm_page * instead of a physical address, vm_page_zero_fill()
and vm_page_zero_fill_area() have served no purpose.
a pointer to a symbol is given and we have to find the containing symbol
table. We do this by bounds checking. For some strange reason (ie I
haven't found the root cause) the first test succeeded for said symbol,
implying that the symbol came from the .dynsym table. In reality however
the symbol actually resided in the .symtab table. Needless to say that
all that was returned was junk.
The upper bounds check was: (symptr - baseptr) < symtab_size
This has been rewritten to: symptr < (baseptr + symtab_size)
As a side-effect, slightly more optimal (and still correct :-) code can
be generated on ia64.
some circumstances when we get a select collision, we can end up with
cases where we do not clear some sip->si_thread on the way out, leading to
page faults in selwakeup(). This should solve the problem where postfix
can crash the kernel during select collisions.

This state is to allow some experimentation and not YET used..
The theory is that a thread that is about to sleep is placed on the sleep
queue and then discovers it should suspend, and is placed on suspend queue.
(these are separate queues and it can be on both). It will not become runnable
until it has been removed from BOTH queues. i.e. a wakeup event
has occured AND the process has been unsuspended. If it were not on the sleep
queue when suspended, then the (possibly only) wakeup event might arrive and
not find any process to wake up. this would result in the thread
sleeping 'forever' when the suspension is lifted. This state will
transition to one of TDS_SLP or TDS_SUSPENDED, depending upon which
constraint is lifted first.

These types are unlikely to ever become very MD. They include:
clockid_t, ct_rune_t, fflags_t, intrmask_t, mbstate_t, off_t, pid_t,
rune_t, socklen_t, timer_t, wchar_t, and wint_t.
While moving them, make a few adjustments (submitted by bde):
o __ct_rune_t needs to be precisely `int', not necessarily __int32_t,
since the arg type of the ctype functions is int.
o __rune_t, __wchar_t and __wint_t inherit this via a typedef of
__ct_rune_t.
o Some minor wording changes in the comment blocks for ct_rune_t and
mbstate_t.
