o Big performance improvement.  The version of the driver in the kernel
  still had a "mdelay(1)" after every register write.  This capped
  performance at about 8Mbps and ate tons of CPU time.  (Luckily, most
  users of this card are just terminating a DSL line where its not too
  noticeable)

  However, after removing this delay the card started getting out of
  sync with the driver under stress tests.  After a couple days of chasing
  the bug I finally determine that the card's support for transmitting
  partial PDUs just doesn't quite work as advertised (before we would send
  a partial PDU to completely fill a VCC's transmit buffer and then send
  the rest of the skb when more buffer space filled up).  The usefulness of
  this is somewhat doubtful anyway and removing it cleaned up a lot of code.

  I also added some memory barriers to make sure operations to the card
  happen in the correct order.

  Now for the first time ever we get near line-rate performance out of this
  card (~19Mb/s TCP in netperf between two ~300Mhz machines)

o Locking changes (essentially the patch Chas sent me a couple weeks ago
  with some minor tweaking)  I'm still not sure we're getting 100% of the
  cases right but it's definitely FAR better than the old lock-less version.

o Cleanup the backlog draining code in lanai_shutdown_tx_vci()

o Remove outdated comment describing how to compile the module

o Got rid of the "service_novcc_[tr]x" stats - it's really the same error
  as "service_[tr]x" - there's no reason to count them separately.

o Use the ATM_25_PCR constant instead of computing it for ourselves

as it uses the crc32 library.

The enclosed patch tries to clean the tulip de4x5 driver, and update
it to some of the 2.6 APIs :

- Use PCI and EISA probing APIs
- Use generic DMA API
- Fix DE425 init on the Jensen
- Remove de4x5 from Space.c

It's been tested on x86 and Alpha, with a DE425 (21040, EISA), a DE435
(21040, PCI) and a quad DLink (4*21143, PCI).

The major problem with this patch is that, because of the Space.c
removal, interfaces get potentially renumbered. This has been
discussed to death on lkml, without any obvious solution. IMHO, we'd
better remove as many drivers as we can from Space.c before
2.6.0-final ships...

forced into double negatives.

the compilation of cosa.c was already fixed in your BK tree, so we can
now remove the dependency on BROKEN.

This fixes the build of the via-pmu.c driver when CONFIG_PMAC_PBOOK is
not set.

From Benjamin Herrenschmidt <benh@kernel.crashing.org>:

This adds the Kconfig option for the PowerMac IDE driver "LED" feature
(using the laptop's front LED as a disk activity indicator).  It also
adds a small bit to ide-probe.c that was missing from Jens patch when he
added the activity function infrastructure.  He did add the hwif field,
but not the code to actually enable it.

From Daniela Engert <dani@ngrt.de>.

It was disabled to workaround a bug in a driver.  The orginal bug was
fixed but the workaround was not removed.

This has three main parts: (1) support for the 440GP and 440GX processors,
(2) support for the "Ebony" and "Ocotea" reference boards for those processors,
and (3) support for 64-bit physical addresses.  The 440GP and 440GX are "Book E"
processors, and this introduces a CONFIG_BOOKE and some definitions that apply
to all Book E processors.

Having 64-bit physical addresses means that PTEs are now 64 bits.  The PTE pages
stay at 4kB, and the pgdir expands to 8kB.

amiflop didn't init the queue before assigning it to disk->queue. the
error handling was also immensely screwed, I've cleaned that up too.

This makes "allyesconfig" do a better job.

broken on SMP (due to expecting global irq locking).

AFAICT this is ready for your next merge with Linus.

Ben's ohci stuff was not cooked yet, seemed like the
pm stuff wasn't yet supporting the hook(s) he needed.
RMK had similar issues w.r.t. PM on ARM too.


This patch includes:

   - updates from Benjamin Herrenschmidt to make usbcore
     behave a bit better during PM suspend (setting and
     checking hcd state).

   - related updates from me, making more paths into hcds
     fail when the driver is suspended.

   - updates based on some feedback from Alan Stern,
     notably including getting rid of a state we don't
     really need (most of the patch, by volume).

   - an experiment that tries to give a warning in the
     sadly common case of ACPI or APIC (etc) settings
     that need to change before USB works.

Net effect is that some of the PM issues start to get
resolved, maybe IRQ problems will be diagnosed quicker,
and some overdue cleanup gets started.

Please merge this minor fix:

   - loosen constraints on buffer allocation

This is needed before Alan's file-backed storage
gadget driver will initialize using net2280.
