io or memory space access enabled. This patch defers the setting
of these bits until after all of the mapping registers are probed.
It might be even better to defer this until a particular mapping
is activated and to disable that type of access when a new
register is activated.
2) The PCI spec is very explicit about how mapping registers and
the expansion ROM mapping register should be probed. This patch
makes cardbus_add_map() follow the spec.
3) The PCI spec allows a device to use the same address decoder for
expansion ROM access as is used for memory mapped register access.
This patch carefully enables and disables ROM access along with
resource (de)activiation.
This doesn't include the prefetching detection stuff (maybe later when code is written to actually turn on prefetching). It also does not use the PCI definitions (yet, I'll try to put this in all at once later)

- Make pccbb/cardbus kld loadable and unloadable.
- Make pccbb/cardbus use the power interface from pccard instead of inventing its own.
- some other minor fixes
Clarify message for previous commit (addition of "bogomips"):
IBM JDK was not broken in common sense, but its JIT (Just In Time bytecode
compiler) uses number of occurences of "bogomips" in data read from
/proc/cpuinfo to determine number of processors installed on machine. Number
of processors determined in this "innovative" way then used to optimize JIT
behaviour. Even more strangely that in the absence of "bogomips" in the data
read from /proc/cpuinfo JIT assumes that it runs on SMP system. Since there
is no way to fix misbehaving JIT (binary-only distro), we had to add bogos
"bogomips".
Dike out support for DEC3000/300* Pelic* and the DEC3000/[4-9]00
Flamingo/Sandpiper families, SLIP, lance Ethernet (especially since `le'
based Alphas are diked out now too), POSIX P1003_1B real-time extentions,
and last but not least "NOBLOCKRANDOM" since the random device is removed.
This lets us fit [barely!]:

Created /R/stage/floppies/kern.flp
ppp descriptor and signals the terminal thread when there's something
to read on that descriptor.
This means that the main loop doesn't have to alarm() itself into
dropping out of el_gets() frequently to check the descriptor. This
dropping out was disturbing syscons (via ioctl()s from libedit) enough
to reset the screensaver timeout every .5 of a second.
PR: 20345
The release engineer keeps using the wrong /boot/cdboot when creating the
ISO images. So we'll add the 4.0-RELEASE cdboot to the tree until someone
bothers to fix the source so a working `cdboot' is built.
1) mpsafe (protect the refcount with a mutex).
2) reduce duplicated code by removing the inlined crdup() from crcopy()
and make crcopy() call crdup().
3) use M_ZERO flag when allocating initial structs instead of calling bzero
after allocation.
4) expand the size of the refcount from a u_short to an u_int, by using
shorts we might have an overflow.
