from user mode. Don't disable interrupts when returning from vm86 mode
to user mode either. Now, we only disable interrupts before calling a
hardware interrupt handler, which is the only time we _should_ be
disabling interrupts.
Because of this, err, feature, any routine that one called in vm86 mode
had to re-enable interrupts by setting the interrupt flag or interrupts
would remain disabled even after the routine returned. For example, I
have a simple debugging routine that uses a vm86 mode function to dump
any arbitrary memory word that I use to read the BIOS timer or any other
memory location. This function does 1 load instruction from memory and
then returns. Since it didn't re-enable interrupts, the first time I
called it to read the BIOS timer, it disabled interrupts. This also
affected the PXE bootstrap as it needs interrupts enabled while it is
processing. This patch fixes both of those situations so that those
functions do not worry about having to enable interrupts. Hardware
interrupt handlers worked fine with the old code because they always
enable interrupts as part of their routine.
If you have any problems with the loader after this commit, please
let me know. I'd like to MFC it in a week or two since PXE support
needs it.

. Bring PicoBSD up to date with -CURRENT reality.
. Make PicoBSD smart and not spam /dev/vn0 and /mnt. Now it uses the first
unused vn device and creates a temporary mountpoint in /tmp.
. Miscellaneous build cleanups and optimizations.
Unfortunately the bridge, isp, and router floppies are too big and need
the axe treatment. The install floppy needs updating to -CURRENT. Dial and
net build and (appear to) run OK. I will be adressing these in the
near future (unless someone beats me to it :-) ).

in struct bio. Eventually, bio_offset will probably obsolete the
bio_blkno and bio_pblkno fields.
Remove the special hack in atapi-cd.c to determine of bio_offset was valid.
that seems to be working (I have a MF card that has a 336 modem and
ethernet that the probe routine finds, but the attach fails on because
pccardd doesn't do what you'd like with MF cards all the time).
serial gdb: interrupts were causing either overruns or stealing
characters. Put splhigh() around the routines which transfer packets
across the line. Since this happens when the system is halted in
debug, this doesn't cause any particular problem. Now it is possible
to run the link at 115,200 bps.
PR: (not assigned yet, must be in limbo somewhere)
Add partial support for detecting non-existent gdb devices.
Add $FreeBSD$ tag.
* Report link errors to stdout with uprintf() so that the user can see
what went wrong (PR kern/9214).
* Add support code to allow module symbols to be loaded into GDB using
the debugger's "sharedlibrary" command.
Removed NETBSDTX spares.
Renamed a load of functions - specifcally
start -> tx
init has download, sj and assoc as sub-functions
report_params and update params move to repparams/upparams
Tidied up old #define's
Got rid of old DPRINTF, made printf's RAY_PRINTF and panic's RAY_PANIC
All code KNF
Removed checking the ECF_TO_HOST area in ray_init - this gets hosed
when someone updates/read a parameter from the card so causes
unneeded grief. This required moving the tib check into ray_attach.
Changed handling of interface flags in ioctl so that promiscous mode
changes are only done as needed.
Sequences of comq entries can be added to an array and automatically
dealt with - used in ray_init_user and others.
Moved IFF_RUNNING checks from the comq commands to com_runq - still
not sure what to do so we PANIC - will be fixed.
ray_sj now checks to see if any of the parameters it can update can be
updated.
ray_sj_done now updates parameters to the current n/w set if we changed
them earlier. I was being a bit thick in earlier comments as to why this
check was done - the ECF never changes the parameters.
Assocication with APs is handled outside of ray_sj - need to add
WEP stuff if I ever get my hands on an AP.
ray_stop, ray_unload and ray_reset are currently broken - reset isn't used anyway.
ray_tx_XXX and ray_rx only have cosmetic changes.
Interrupt handler now gets command out of ccs. This is so ray_intr_ccs and
ray_intr_rcs don't need to remap CM (I'm trying to roll things up a bit as
it must be slowing us down).
ray_intr_ccs just vectors commands to functions or error checks - a
jump table could replace it in ray_intr.
Ditto for ray_intr_rcs.
mcast is currently broken - I need to do more work for ALLMULTI etc. This is reasonably easy to fix becuase of the comq array stuff.
Added a few more checks into repparams so that it is firmware version aware. It also uses the new comq framework.
Parameter updating is also much better with the update parameter return routine re-worked.
Added a couple of runq entry helper functions - one that malloc's a new
entry and fills it in with sensible defaults and another that adds and
runs a seqencue of entries.
