In other words, fix this after it broke when another piece of the
code was fixed. Ain't programming fun?

uhmodem: device driver for huawei 3G wireless modem
* what it is?
A device driver for huawei 3G wireless modem, E220 and its valiations.
The devices are very simuler to ubsa device, but they need special care
to use as modem device.
This patch introduce "uhmodem (USB Huawei modem)" for the devices.
A uhmodem device has two com devices and one USB mass strage device.
The driver enable to use all of them.

reference, but mark the cache 'invalid'. Let the next user of the
route cache check to whether or not the cache is valid, and update
the rtentry reference if necessary. In this way, avoid hairy
splnet()/splx() protection of route caches, which I never did trust.
elansc(4).
elanpex(4) is for PCI exception reporting. I've already found some
kernel bugs by reading the exceptions reported. Beware that it
will spam the console a lot while the kernel and pcictl(8) probe
non-existing addresses in PCI configuration space.
elanpar(4) protects the kernel text from writes by the CPU and by
PCI bus masters. As you might guess, this is not compatible with
setting breakpoints using a debugger; detach the device using
'drvctl -d elanpar0' before you try to set breakpoints. In the
future, I hope to extend elanpar(4) to provide general-purpose RAM
write-protection.
sizeof(*bconfig) not sizeof(bconfig)
Now a small kernel will boot up on my RISC-PC, an install kernel won't
though, it hangs at the switch from RISC-OS to NetBSD.
which we ought to never do. If we have not hooked IRQ 13, we do
not need any resources in npx_softc to handle numeric coprocessor
exceptions, so let npx@isa detach.
- use a hash rather than SPLAY trees.
SPLAY tree is a wrong algorithm to use here.
will be revisited if it slows down anything other than
micro-benchmarks.
- optimize the single mapping case (it's a common case) by
embedding an entry into mdpage.
- don't keep a pmap pointer as it can be obtained from ptp.
(discussed on port-i386 some years ago.)
ideally, a single paddr_t should be enough to describe a pte.
but it needs some more thoughts as it can increase computational
costs.
- pmap_enter: simplify and fix races with pmap_sync_pv.
- don't bother to lock pm_obj[i] where i > 0, unless DIAGNOSTIC.
- kill mp_link to save space.
- add many KASSERTs.
