421edf71f1 When fsync'ing a file on a filesystem using soft updates, we first try
to write all the dirty blocks. If some of those blocks have dependencies,
they will be remarked dirty when the I/O completes. On systems with
really fast I/O systems, it is possible to get in an infinite loop trying
to flush the buffers, because the I/O finishes before we can get all the
dirty buffers off the v_dirtyblkhd list and into the I/O queue. (The
previous algorithm looped over the v_dirtyblkhd list writing out buffers
until the list emptied.) So, now we mark each buffer that we try to
write so that we can distinguish the ones that are being remarked dirty
from those that we have not yet tried to flush. Once we have tried to
push every buffer once, we then push any associated metadata that is
causing the remaining buffers to be redirtied.

6f8b8ad7c0 Finally!!
The much roumored replacement for our current IDE/ATA/ATAPI is
materialising in the CVS repositories around the globe.

So what does this bring us:

A new reengineered ATA/ATAPI subsystem, that tries to overcome
most of the deficiencies with the current drivers.

It supports PCI as well as ISA devices without all the hackery
in ide_pci.c to make PCI devices look like ISA counterparts.

It doesn't have the excessive wait problem on probe, in fact you
shouldn't notice any delay when your devices are getting probed.

Probing and attaching of devices are postponed until interrupts
are enabled (well almost, not finished yet for disks), making
things alot cleaner.

Improved performance, although DMA support is still WIP and not
in this pre alpha release, worldstone is faster with the new
driver compared to the old even with DMA.

So what does it take away:

There is NO support for old MFM/RLL/ESDI disks.
There is NO support for bad144, if your disk is bad, ditch it, it has
already outgrown its internal spare sectors, and is dying.

For you to try this out, you will have to modify your kernel config
file to use the "ata" controller instead of all wdc? entries.

example:

# for a PCI only system (most modern machines)
controller 	ata0
device		atadisk0	# ATA disks
device		atapicd0	# ATAPI CDROM's
device		atapist0	# ATAPI tapes

#You should add the following on ISA systems:
controller	ata1	at isa? port "IO_WD1" bio irq 14
controller	ata2	at isa? port "IO_WD2" bio irq 15

You can leave it all in there, the system knows how to manage.

For now this driver reuses the device entries from the old system
(that will probably change later), but remember that disks are
now numbered in the sequence they are found (like the SCSI system)
not as absolute positions as the old system.

Although I have tested this on all the systems I can get my hands on,
there might very well be gremlins in there, so use AT YOU OWN RISK!!
This is still WIP, so there are lots of rough edges and unfinished
things in there, and what I have in my lab might look very different
from whats in CVS at any given time. So please have all eventual
changes go through me, or chances are they just dissapears...

I would very much like to hear from you, both good and bad news
are very welcome.

Enjoy!!

edb6a1c40f Close PR #10264. Don't bail directly out of passwd/chpass in my_yp_match().
Instead, treat the inability to retrieve a record from the server as a
match failure and let things take its course.

Part of the problem here is that NIS _is_ turned on, however the master
server is actually not an NIS server: it's an NIS+ server. And the client
is bound to an NIS+ replica server that's running in YP compat mode.
The code which tries to figure out of the user is local or NIS gets
confused by this.

03ea38a673 Don't define MACHINE, MACHINE_ARCH, _MACHINE or _MACHINE_ARCH if

4697c1d0cc Add TARGET_ARCH=mipsel and TARGET_ARCH=mipseb as a valid targets.
Unlike the unisex architecutres we've had so far, mips is bisexual.
These tools can produce either byte sex, and the compiler/make
determines the proper gender to use.  Otherwise, we'd have to have had
mipsel and mipseb in all the places that we have just mips.  And there
are other complications with doing that (binutils doesn't like to
build mips tools without both byte genders, it seems).

Introduced BINUTIL_ARCH so that other bisexual architectures can a
generic mechanism.

We cannot just define MACHINE_ARCH as mips because we need to
differentiate big and little endian types of binaries.  Discussions on
freebsd-arch have hashed out this issue (and the parallel libc
issues).  NetBSD is moving towards mipsel and mipseb for their two
flavors of mips ports (in time for 1.4, if this change hasn't already
been accomplished).

I've been building i386 worlds with this tree for a three months with
these files in place with no ill effects.

57b9785287 Comment why we do a TLF when we get a ``Down'' event in state
``closing''.

Pointed out by: archie

Don't do a TLF when we get a ``Catastrphic Protocol Reject'' event
in state ``closed'' or ``stopped''.

Pointed out but not suggested by: archie

This makes no difference in the current implementation as
LcpLayerFinish() does nothing but log the event, but I disagree
in principle because it unbalances the TLF/TLS calls which
(IMHO) doesn't fit with the intentions of the RFC.

Maybe the RFC author had a reason for this.  It can only happen
in two circumstances:

- if LCP has already been negotiated then stopped or closed and we
  receive a protocol reject, then we must already have done a TLF.
  Why do one again and stay in the same state ?

- if LCP hasn't yet been started and we receive an unsolicted
  protocol reject, why should we TLF when we haven't done a TLS ?

b9dfdf0276 Bring up auto links despite there being no data queued if
we're already in network phase and our autoload values
are set with no minimum threshold (the default).

Tell the autoload timer that it's ``coming up'' *before*
calling AutoLoadTimeout() directly... not after.  This
prevents the very first demand-dial connection from
immediately disconnecting when there are other auto links.

6d8d63664b Removed all traces of `p_switchtime'. The relevant timestamp is per-cpu,
not per-process.  Keep it in `switchtime' consistently.

It is now clear that the timestamp is always valid in fork_trampoline()
except when the child is running on a previously idle cpu, which
can only happen if there are multiple cpus, so don't check or set
the timestamp in fork_trampoline except in the (i386) SMP case.
Just remove the alpha code for setting it unconditionally, since
there is no SMP case for alpha and the code had rotted.
