probably be uintmax_t but I didn't feel like adding all the extra includes.
these were cosmetic. However, at least two of these changes fix bugs
where a (fake) pointer to a RX descriptor was added to the physical
memory start address with the cast in the wrong place resulting in
rxdesc[pmem_start] instead of (uintptr_t)rxdesc + pmem_start.
just limited to the DEVICE_POLLING case. This removes the FXP_RFA_RNRMARK
hack, and replaces it with a softc flag that is used to record when
the handling of a no-resource condition was deferred due to running
out of DEVICE_POLLING cycles. This was tested on -stable, but the
code is essentially the same as in -current. It should only affect
the case where DEVICE_POLLING is defined.
The details of the mechanism behind the crashes are still uncertain
but the most likely cause seems to be some kind of hardware confusion
when the no-resource recovery code is accidentally invoked while
the receiver is still active. This could have happened if the
hardware left the 0x4000 bit of the RFA status word set. The comments
in the commit log for revision 1.142 stating that the driver could
clash with the hardware writing to this status word were not correct.

a kernel virtual address for a phyiscal address by adding KERNBASE to the
physical address. It also tries to read values out of a the PC BIOS on
all archs. It also uses "manual" inb() and outb()'s to talk to the mcclock
device which just happens to be at that location on both i386 and alpha.
This driver should likely be i386-only.

Call acpi_cmbat_init_battery() from acpi_cmbat_resume() too just in

This is a workaround for embedded controller operations which is
unstable for about a minute (typically 30 or 40 sec.) at boot time.
o Always release the resources on device detach.
o Attach resources the same with driver added as we do we do in the insert
case (maybe this should be a routine).
o signal the wakeup of the thread on resume instead of trying to force an

o Minor debug hacks.
o use 0xffffffff instead of -1 for uint32_t items.
o Don't complain when we're asked to detach no cards. This is normal.

In some ACPI BIOS implementations, boot disabled devices don't have

Also it is not fatal if getting current IRQ of boot disabled devices

across system suspends on the Intel 82371AB PCI-ISA bridge. On a
Sony Vaio C1XD that I have, these registers are not set correctly
after an ACPI resume. The result is that after resuming, a shared
IRQ is left in edge-triggered mode so the interrupt can later become
jammed in a state where the line remains asserted, but the handler
is never called.

behaviour of the hardware: a possibly reserved bit of the receive
descriptor (RFA) `status' field is borrowed to record no-resource
(RNR) events, and the same status field is read and written to at
a time that may clash with the hardware updating this field.
There is no hardware documentation available to determine if these
things are safe to do; the second issue almost certainly isn't, and
the first is only safe if there is documentation saying that this
bit is free to be used by the driver. The PR referenced below
provides extremely convincing evidence that the changes cause random
crashes on some (unusual) hardware.
Since these features are only required by the DEVICE_POLLING case,
this commit makes their use conditional on that option. It does not
change the DEVICE_POLLING case, but at least people with the rare
hardware on which this code causes problems can now avoid the crashes
by not enabling DEVICE_POLLING.

- Add detach support to the driver so that you can kldunload the module.
Note that currently rc_detach() fails to detach a unit if any of its

creation by GCC-2.6.3. Casting pointers to unsigned char
to volatile pointers to unsigned char seemed to produce
better results on the ia32 architecture with old versions
of GCC.
The current FreeBSD system compiler GCC-3.2.1 emits
better sign extension code for non-volatile variables:
volatile char c;
int i = c;
is compiled to:
...
movb -1(%ebp), %al
movbsl %al, %eax
movl %eax, -8(%ebp)
...
char c;
int i = c;
is compiled to:
...
movbsl -1(%ebp), %eax
movl %eax, -8(%ebp)
...
The same holds for zero-extension of dereferenced pointers
to volatile unsigned char.
When compiled on alpha or sparc64, the code produced for the
two examples above does not differ.
* Change atapi-cd ioctls to use the same units.
* Change burncd, cdcontrol to convert CDROM speed to KB/sec before
calling the ioctl. Add a "max" speed option for their command lines.
This change does not break ABI but does change the units passed through
the ioctl so 3rd party software that uses cdrio.h will have to convert
(most likely by multiplying CDROM speed by 177 to get KB/s).
