bus to use. We need to set it here.
This fixes the problem where a probe routine establishes and
disestablishes the interrupt and then we get a panic in the probe
routine.
However, we pass the pointer to the interrupt hanlder count to the
parent bus, which writes its own cookie there, so there may be some
problems with that which isn't apparent at the moment.
Commit made from: laptop running NEWCARD with sn driver (which works,
but gets the wrong ethernet address).
o Fix OLDCARD to use the new interface.
o Rename the offsetp argument to deltap to more closely reflect what it
is returning (it returns the delta from the requested value to the actual
value).
o Remove duplicate $FreeBSD$ in pccbb.c
o Allow deltap to be NULL.
o Convert new isa pcic driver and add XXX comments that this function isn't
actually implemented there (which means that NEWCARD pccard stuff won't
work there until it is).
o Revert attempts to make old inferface work in NEWCARD.

scanner/parser. FreeBSD recently made 'flex' its default implementation
of 'lex'. One of the incompatibilities of 'flex' vs. 'lex' is that
if you longjmp() out of the scanner, you must call yyrestart()
before doing another scan (as documented in flex(1)). So add an
invocation to yyrestart() in lex_init(). This change should be
backwards compatible with the original 'lex'.

- pccbb no longer needs to remember whether a card is inserted.
- pccbb reissues insertion on load of cardbus/pccard modules.
- got rid of unnecessary delays in power functions.
- Cardbus children are no longer deleted if probe/attach fails.
- non-attached child devices are reprobed at driver_added.
* CARD interface to read CIS
- added card_cis_read/card_cis_free interface to read arbitrary CIS
data. This currently is only implemented in cardbus.
* pccard begins to work
- pccard can now use higher memory space (and uses it by default).
- set_memory_offset interface changed.
- fixed ccr access, which was broken at multiple locations.
- implement an interrupt handler - pccard can now share interrupts.
- resource alloc/release/activate/deactivate functions gutted: some
resources are allocated by the bridge before the child device is
probed or attached. Thus the resource "belongs" to the bridge, and
the pccard_*_resource functions need to fudge the owner/rid.
- changed some error conditions to panics to speed debugging.
* Mutex fix - Giant is entered at the beginning of thread
as multi-processor kernels. The old way made it difficult for kernel
modules to be portable between uni-processor and multi-processor
kernels. It is no longer necessary to jump through hoops.
- always load %fs with the private segment on entry to the kernel
- change the type of the self referntial pointer from struct privatespace
to struct globaldata
- make the globaldata symbol have value 0 in all cases, so the symbols
in globals.s are always offsets, not aliases for fields in globaldata
- define the globaldata space used for uniprocessor kernels in C, rather
than assembler
- change the assmebly language accessors to use %fs, add a macro
PCPU_ADDR(member, reg), which loads the register reg with the address
of the per-cpu variable member
- Provide TUNABLE_INT() hooks for ktr_cpumask, ktr_mask, and ktr_verbose
so that they can be set from the loader by their respective sysctl names.
For example, to turn on KTR_INTR and KTR_PROC in ktr_mask, one could
stick 'debug.ktr.mask="0x1200"' in /boot/loader.conf.

This is needed when linking statically as SVR4 (ie, ELF) behavior is to only
link in a module if it satisfies an undefined strong reference from somewhere.
(this surprises a lot of people) Things are different when using shared libs,
the entire library and its modules and their symbols are available at run-time
(when the weak reference is seen to still be unsatisfied and is satisfied on
the spot), this is not the case with static libs.
Thus one can have a static binary with unresolved week references, and at
run-time dereference a NULL pointer.
