Fix broken suspend/resume in ohci1394
I've been experimenting to track down the cause of suspend/resume problems
on my Compaq Presario X1050 laptop:
http://bugzilla.kernel.org/show_bug.cgi?id=6075
Essentially the ACPI Embedded Controller and keyboard controller would
get into a bizarre, confused state after resume.
I found that unloading the ohci1394 module before suspend and reloading it
after resume made the problem go away. Diffing the dmesg output from
resume, with and without the module loaded, I found that with the module
loaded I was missing these:
PM: Writing back config space on device 0000:02:00.0 at offset 1. (Was
2100080, writing
2100007)
PM: Writing back config space on device 0000:02:00.0 at offset 3. (Was 0, writing 8008)
PM: Writing back config space on device 0000:02:00.0 at offset 4. (Was 0, writing
90200000)
PM: Writing back config space on device 0000:02:00.0 at offset 5. (Was 1, writing 2401)
PM: Writing back config space on device 0000:02:00.0 at offset f. (Was
20000100, writing
2000010a)
The default PCI driver performs the pci_restore_state when no driver is
loaded for the device. When the ohci1394 driver is loaded, it is supposed
to do this, however it appears not to do so.
I created the patch below and tested it, and it appears to resolve the
suspend problems I was having with the module loaded. I only added in the
pci_save_state and pci_restore_state - however, though I know little of
this hardware, surely the driver should really be doing more than this when
suspending and resuming? Currently it does almost nothing, what if there
are commands in progress, etc?

Like in patch ''ohci1394, sbp2: fix "scsi_add_device failed"

This choice is only relevant for adapters which actually have a
programmable pysical upper bound register. (Only ALi and
Fujitsu adapters are known for this. Most adapters have a fixed
bound at 4 GB.) The middle address range is suitable for posted
writes.
AFAIK, PCILynx does not support physical DMA nor posted writes,

[PATCH] Fix for the PPTP hangs that have been reported
People have been reporting that PPP connections over ptys, such as
used with PPTP, will hang randomly when transferring large amounts of
data, for instance in http://bugzilla.kernel.org/show_bug.cgi?id=6530.
I have managed to reproduce the problem, and the patch below fixes the
actual cause.
The problem is not in fact in ppp_async.c but in n_tty.c. What
happens is that when pptp reads from the pty, we call read_chan() in
drivers/char/n_tty.c on the master side of the pty. That copies all
the characters out of its buffer to userspace and then calls
check_unthrottle(), which calls the pty unthrottle routine, which
calls tty_wakeup on the slave side, which calls ppp_asynctty_wakeup,
which calls tasklet_schedule. So far so good. Since we are in
process context, the tasklet runs immediately and calls
ppp_async_process(), which calls ppp_async_push, which calls the
tty->driver->write function to send some more output.
However, tty->driver->write() returns zero, because the master
tty->receive_room is still zero. We haven't returned from
check_unthrottle() yet, and read_chan() only updates tty->receive_room
_after_ calling check_unthrottle. That means that the driver->write
call in ppp_async_process() returns 0. That would be fine if we were
going to get a subsequent wakeup call, but we aren't (we just had it,
and the buffer is now empty).
The solution is for n_tty.c to update tty->receive_room _before_
calling the driver unthrottle routine. The patch below does this.
With this patch I was able to transfer a 900MB file over a PPTP
connection (taking about 25 minutes), whereas without the patch the
connection would always stall in under a minute.

[PATCH] Further alterations for memory barrier document
From: David Howells <dhowells@redhat.com>
Apply some alterations to the memory barrier document that I worked out
with Paul McKenney of IBM, plus some of the alterations suggested by Alan
Stern.
The following changes were made:
(*) One of the examples given for what can happen with overlapping memory
barriers was wrong.
(*) The description of general memory barriers said that a general barrier is
a combination of a read barrier and a write barrier. This isn't entirely
true: it implies both, but is more than a combination of both.
(*) The first example in the "SMP Barrier Pairing" section was wrong: the
loads around the read barrier need to touch the memory locations in the
opposite order to the stores around the write barrier.
(*) Added a note to make explicit that the loads should be in reverse order to
the stores.
(*) Adjusted the diagrams in the "Examples Of Memory Barrier Sequences"
section to make them clearer. Added a couple of diagrams to make it more
clear as to how it could go wrong without the barrier.
(*) Added a section on memory speculation.
(*) Dropped any references to memory allocation routines doing memory
barriers. They may do sometimes, but it can't be relied on. This may be
worthy of further documentation later.
(*) Made the fact that a LOCK followed by an UNLOCK should not be considered a
full memory barrier more explicit and gave an example.

[PATCH] elevator switching race
There's a race between shutting down one io scheduler and firing up the
next, in which a new io could enter and cause the io scheduler to be
invoked with bad or NULL data.
To fix this, we need to maintain the queue lock for a bit longer.
Unfortunately we cannot do that, since the elevator init requires to be
run without the lock held. This isn't easily fixable, without also
changing the mempool API. So split the initialization into two parts,
and alloc-init operation and an attach operation. Then we can
preallocate the io scheduler and related structures, and run the attach
inside the lock after we detach the old one.
This patch has survived 30 minutes of 1 second io scheduler switching

[TCP]: Avoid skb_pull if possible when trimming head
Trimming the head of an skb by calling skb_pull can cause the packet
to become unaligned if the length pulled is odd. Since the length is
entirely arbitrary for a FIN packet carrying data, this is actually
quite common.
Unaligned data is not the end of the world, but we should avoid it if
it's easily done. In this case it is trivial. Since we're discarding
all of the head data it doesn't matter whether we move skb->data forward
or back.
However, it is still possible to have unaligned skb->data in general.
So network drivers should be prepared to handle it instead of crashing.
This patch also adds an unlikely marking on len < headlen since partial
ACKs on head data are extremely rare in the wild. As the return value
of __pskb_trim_head is no longer ever NULL that has been removed.
