Introduce d_version field in struct cdevsw, this must always be
initialized to D_VERSION.
Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing
four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.

Free approx 86 major numbers with a mostly automatically generated patch.

high as after tsleep().
- Replace selwakeup()s with selwakeuppri()s and pass appropriate
priorities.
- Add cv_broadcastpri() which raises the priority of the broadcast
threads. Used by selwakeuppri() if collision occurs.

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.
This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

between pccardd/pccardc and drivers. As far as I can tell no drivers
try to use window 4, so this should be a no-op for them.

o ToPIC is happy with two cards now, even when the two cards are
modems.
o Fix (all?) hangs on boot when power is applied to the card. I
suspect that this will make the Ricoh bridges happier and also
make a lot of VAIO owners happy (confirm to me in private email
please :-).
o All Cardbus bridges should now support 3.3V, X.XV and Y.YV cards,
to the extent that the underlying hardware supports such cards.
(X.X and Y.Y haven't been assigned values yet :-).
o Better 3.3V support for Ricoh ISA bridges.
How:
o Don't mess with the power register when scanning the cards. It
is unnecessary and causes BADVcc conditions on many chipsets. These
in turn can cause an interrupt storm.
o Make pcic_disable reset the slot's voltage.
o Move initializing voltage for the slot until after it has been
disabled.
o Fix a lot of issues with the pcic_cardbus_power routine. We
now properly enable the card and take it out of reset after
a power change.
o When detecting the card's voltage, if we're in a BadVcc state,
direct the bridge to rescan the card for what it supports.
(we might need to in the future set the power register to 0
before doing this).
o Don't preserve CLKSTOP. need to revisit this.
o Better support for Ricoh ISA bridges for 3.3V cards.
o Don't write to PCIC_POWER directly as offten, but instead go
through the pcic_power interface.
o All cardbus bridges now default to use cardbus power control.
o Add misc register definitions.
o remove some (now) bogus comments.
Extra Special Thanks To: Scott Lamber for his kind and generous loan
of a Toshiba laptop with a ToPIC 100 in it for my use.

general cleanup of the API. The entire API now consists of two functions
similar to the pre-KSE API. The suser() function takes a thread pointer
as its only argument. The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0. The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

value (-1) in lue of 50 (which assumes a 5.0V card). The rest of the
pccard system doesn't detect the proper voltage for the card, so we have
to do it on powerup. Many (all?) 3.3V cards can tolerate 5.0V for reading
the CIS, but may fail to operate properly when so powered.

again? That NEVER works!" "This time for sure!"
Minor overhaul of how we do interrupts for the pci interrupt routing
case to cope with card ejection better (read: make it not hand on so
many cards):
o Reintroduce func_intr and func_arg and use the to store the
interrupt handler to call.
o Create a pcic_pci_func_intr to call the real interrupt handler
iff the card hasn't been ejected.
o Remove some checks in pcic_setup_intr now that it is used
exclusively for isa routed interrupts.
o Defer the eject event until later too, but make sure we can't
do any client driver ISR calling in the interrum.
o Add some simple code to make sure that we don't attach more
than one child. This should fix pccardd starting twice
problem (ala single user -> multi-user when you started pccardd
by hand in SU).

make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

o Move PIOCSRESOURCE from pccard to pcic so the kernel can give pccardd
better hints as to what resources to use.
o Implement an undocumented hw.pcic.interrupt_route to allow people that
need to do so to route their interrupts in a non-standard way.
o Only preallocate a resource in probe if we're routing via pci.
o If we aren't routing via pci, then set the irq to use explicitly
to defeat the automatic IRQ routing of the pci layer.
This, with the pccardd code should be close to what can be committed
to -stable.

o Powerstate interface is now available as of 430002, not 500000 (note that
this change will be not 100% correct since the power state stuff didn't
enter current until well after 500000, but it is good enough for the two

power x 0.
pccardc power x 0 used to disable the slot. But a suspend/resume
would reactivate the pccard. It no longer does that. Now the
disabling of the slot is sticy until it is reset with power x 1 or the
card is ejected. This seems closer to correct behavior to me.
o Process all card state changes the same using pccard_do_stat_change().
o Cleanup disabling the card so that we can preserve the state after
the change. Basically, don't set it to empty as often as we do.
o On suspend, the new state is "empty" and the laststate is "suspend"
o Document state machine with a diagram of states and edges. The
edges are labeld to tell the reader what event causes the external
state changes.
o "machdep.pccard.pcic_resume_reset" may be obsolete now. We always
call the bridge driver's resume method on resume now. Otherwise cards
won't automatically show up. If it needs to stay, I'll add it back.

Print type of pci bridge we find.
Force the IRQ of pci bridges upon all its children.
Allocate the resources on behalf of the bridge when we're testing to see if
they exist.

Use bus_alloc_resource to get the memory that we'll be using. Also

Second, move PIOCSRESOURCE to its own routine and make it conform more

routine instead of pccard_event(). This avoids spurious extra calls
to pccard_insert_beep() at insert or remove time which could occur
due to noise on the card-present lines.
Clean up some code in pccard_beep.c; we were depending on the order
of evaluation of function arguments, which is undefined in C. Also,
use `0' rather than `NULL' for integer values.
