already allow this for NFS swap configured via BOOTP, so it is
known to work fine.
For many diskless configurations is is more flexible to have the
client set up swapping itself; it can recreate a sparse swap file
to save on server space for example, and it works with a non-NFS
root filesystem such as an in-kernel filesystem image.
strictly necessary on current, but having it in here makes the diffs with
stable smaller and doesn't hurt anything except for phk's redundant include
finder.
never completed" message. The RX reset takes longer complete than it
used to, a lot longer in fact than xl_wait() is prepared to wait.
When we do the RX reset in xl_reset(), this cases xl_wait() to time out
and whine. We wait a little extra time now after the RX reset, which
should silence the warning.
Thanks to obrien for finally getting me a box with a NIC that
causes this problem for me to tinker with.
entry (d_ino == 0) is found in a position that is not the start of
a DIRBLKSIZ block.
While such entries cannot occur normally (ufs always extends the
previous entry to cover the free space instead), they do not cause
problems and fsck does not fix them, so panicking is bad.
hw.pcic.irq Globally set the IRQ for all pcic devices' management
interrupt (aka card status change or CSC interrupt)
This is what used to be known as
machdep.pccard.pcic_irq (which has been retained for
now for compatibility).
hw.pcic.ignore_fuction_1 Ignores function 1 for all PCIC bridges by not
attaching to them. Lucent released a huge batch
of cards that were imporperly manufactuered (lacking
the 0 ohm resister to disable slot 1). This is
a big hammer to keep those cards from causing problems
(I've had 4 people contact me saying my patches
worked great once they added a kludge to always ignore
function 1, or until they soldered these resistors
in place!).
No clue where to document these. They act as both boot loader environment
variables, as well as read-only sysctls after boot.
At the same time, sort sys/systm.h in its proper order after sys/sysctl.h.
VM caching of disks through mmap() and stopping syncing of open files
that had their last reference in the fs removed (ie: their unsync'ed
pages get discarded on close already, so I made it stop syncing too).
o kill blank line that I introduced in cardinfo.h
o Delete unused variable wasinactive.
o return 0 from pccard_resume.
o Set the state and lastsate initially to be empty.
o move comment above code for interrupt dispatching.
o Powerstate interface is now available as of 430002, not 500000 (note that
this change will be not 100% correct since the power state stuff didn't
enter current until well after 500000, but it is good enough for the two
branche we have going now).
power x 0.
pccardc power x 0 used to disable the slot. But a suspend/resume
would reactivate the pccard. It no longer does that. Now the
disabling of the slot is sticy until it is reset with power x 1 or the
card is ejected. This seems closer to correct behavior to me.
o Process all card state changes the same using pccard_do_stat_change().
o Cleanup disabling the card so that we can preserve the state after
the change. Basically, don't set it to empty as often as we do.
o On suspend, the new state is "empty" and the laststate is "suspend"
o Document state machine with a diagram of states and edges. The
edges are labeld to tell the reader what event causes the external
state changes.
o "machdep.pccard.pcic_resume_reset" may be obsolete now. We always
call the bridge driver's resume method on resume now. Otherwise cards
won't automatically show up. If it needs to stay, I'll add it back.

longer have a pccard in the slot. This fixes the problem where pccard
would say that a card had been inserted on resume. This also appears
to make the insert/remove events more reliable after a resume as well,
but that may be a different bug I need to hunt down.
initialize in the right order to make derivative settings work right.
eg: at compile time, nmbufs was double nmbclusters. For POLA this should
work the same at runtime.
Tunables are now derived at boot time from maxusers. ie: change maxusers
via a tunable and all the derivative settings change. You can change
the other tunables individually as well. Even hz etc is tunable.
making pcbs available to the outside world. otherwise, we will see

were indices in a dense array. The cpuids are a sparse set and treat
them as such, setting up containers only for CPUs activated during
mb_init().
- Fix netstat(1) and systat(1) to treat the per-CPU stats area as a sparse
map, in accordance with the above.
This allows us to properly boot with certain CPUs disactivated. However, if
we later decide to re-activate said CPUs, we will barf until we decide to
implement CPU spinon/spinoff callback hooks to allow for said CPUs' per-CPU
containers to get configured on their activation.

This has supposedly been incorporated into the Intel code already, so this
will get cleanly replaced with the "official" version when it is next
imported and will not cause any conflicts or hiccups.
- Use sysctl to export stats
- Use ip_encap.c's encapsulation support
- Update lkm to kld (is 6 years a record for a broken module?)
- Remove some unused cruft
effect, which would cause unnecessary route deletion:
* Unfortunately, this has the obnoxious
* property of also triggering for insertion /above/ a pre-existing network
* route and clones. Sigh. This may be fixed some day.
The effect has been even worse, because recent versions of route.c set
the parent rtentry for cloned routes from an interface-direct route.
For example, suppose that we have an interface "ne0" that has an IPv4
subnet "10.0.0.0/24". Then we may have a cloned route like 10.0.0.1
on the interface, whose parent route is 10.0.0.0/24 (to the interface
ne0). Now, when we add the default route (i.e. 0.0.0.0/0),
rt_fixchange() will remove the cloned route 10.0.0.1. The (bad) effect
also prevents rt_setgate from configuring rt_gwroute, which would not
be an intended behavior.
As suggested in the comments to rt_fixchange(), we need stricter check
in the function, to prevent unintentional route deletion.
This fix also solve the "IPV6 panic?" problem in nd6_timer().
