227ee8a188 Eradicate the variable "time" from the kernel, using various measures.
"time" wasn't a atomic variable, so splfoo() protection were needed
around any access to it, unless you just wanted the seconds part.

Most uses of time.tv_sec now uses the new variable time_second instead.

gettime() changed to getmicrotime(0.

Remove a couple of unneeded splfoo() protections, the new getmicrotime()
is atomic, (until Bruce sets a breakpoint in it).

A couple of places needed random data, so use read_random() instead
of mucking about with time which isn't random.

Add a new nfs_curusec() function.

Mark a couple of bogosities involving the now disappeard time variable.

Update ffs_update() to avoid the weird "== &time" checks, by fixing the
one remaining call that passwd &time as args.

Change profiling in ncr.c to use ticks instead of time.  Resolution is
the same.

Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call
hzto() which subtracts time" sequences.

7b778b5e61 Make all file-system (MFS, FFS, NFS, LFS, DEVFS) related option new-style.
This introduce an xxxFS_BOOT for each of the rootable filesystems.
(Presently not required, but encouraged to allow a smooth move of option *FS
to opt_dontuse.h later.)

LFS is temporarily disabled, and will be re-enabled tomorrow.

e1d6dc656d This patch causes the "calltodo" timer list to be decremented by the amount
of time that the laptop was suspending.  Thus, select() calls that might have
suspended rather than firing  at 1hr + "time suspended" since the timer was
posted.

Adding:

    options  APM_FIXUP_CALLTODO

to the kernel config enables the patch.

[
This patch was slightly modified to use a consistant indent style and
I removed some unused local variables.  After this has been tested a
few weeks we'll make the options the default, so for now I'm now
documenting it in LINT.  Mike can later if he wants.

861570bb45 The Libretto's BIOS doesn't set edx on the APM_GETPWSTATUS call, so
the barrery time remaining is reported as a random number.  Initialize
edx to 0xffff in this case, and to 0 in all other cases.  This change
should be benign on other machines.

56fac9328e Expand the APMIO_GETINFO ioctl to return the estimated remaining
battery time.  For backward compatibility with old binaries, I
assigned a new ioctl number for this call, and retained the old
one as APMIO_GETINFO_OLD.  I also added eight words of padding and
a version field, so that future enhancements won't require jumping
through this hoop again.

87f6c6625d Pass 3 of the great devsw changes
most devsw referenced functions are now static, as they are
in the same file as their devsw structure. I've also added DEVFS
support for nearly every device in the system, however
many of the devices have 'incorrect' names under DEVFS
because I couldn't quickly work out the correct naming conventions.
(but devfs won't be coming on line for a month or so anyhow so that doesn't
matter)

If you "OWN" a device which would normally have an entry in /dev
then search for the devfs_add_devsw() entries and munge to make them right..
check out similar devices to see what I might have done in them in you
can't see what's going on..
for a laugh compare conf.c conf.h defore and after... :)
I have not doen DEVFS entries for any DISKSLICE devices yet as that will be
a much more complicated job.. (pass 5 :)

pass 4 will be to make the devsw tables of type (cdevsw * )
rather than (cdevsw)
seems to work here..

53ac6efbd8 OK, that's it..
That's EVERY SINGLE driver that has an entry in conf.c..
my next trick will be to define cdevsw[] and bdevsw[]
as empty arrays and remove all those DAMNED defines as well..

Each of these drivers has a SYSINIT linker set entry
that comes in very early.. and asks teh driver to add it's own
entry to the two devsw[] tables.

some slight reworking of the commits from yesterday (added the SYSINIT
stuff and some usually wrong but token DEVFS entries to all these
devices.

BTW does anyone know where the 'ata' entries in conf.c actually reside?
seems we don't actually have a 'ataopen() etc...

If you want to add a new device in conf.c
please  make sure I know
so I can keep it up to date too..

as before, this is all dependent on #if defined(JREMOD)
(and #ifdef DEVFS in parts)

This stabilizes a couple of APM bioses quite a bit.

top half of the 32bit registers.
Later they do a
|	movw %si,$0x7331
|	movw %ax,0x6(%si)
or something along those lines and crash and burn, because their segment
is already relocated, so adding 0xf0171ce9 to the base of it is bad news.
