f71f5262b1 Add the ability to suspend as well as hibernate to the system. This
is the kernel part of my commits, the userlevel stuff will be done in
a separate commit.  Add the ability to suspend as well as hibernate to
syscons.  Create a new virtual key like hibernate for suspend.  Update
apm_bios.h to define more apm bios goodies.

ecbb00a262 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

f9c9bbc054 If vm86 services are available, use these to perform the APM BIOS
probe and intialisation.  This will ultimately remove the grubby (but
functional) hack that copies a real-mode function into low memory
early in locore.s.

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.

6774cdb846 Whee. Fix two bugs which ended up cancelling each other out.
apm_setup.s was storing apm_cs16_base and apm_cs32_base addresses in
each others slots, and apm.c was reversing the result so the bugs
cancelled out, but the code looked wrong.

No functional differences unfortunately.
