__cfq_get_queue(). __cfq_get_queue() finds an existing queue (struct
cfq_queue) of the current process for the device and returns it. If it's not
found, __cfq_get_queue() creates and returns a new one if __cfq_get_queue() is
called with __GFP_WAIT flag, or __cfq_get_queue() returns NULL (this means that
get_request() fails) if no __GFP_WAIT flag.
On the other hand, in __make_request(), get_request() is called without
__GFP_WAIT flag at the first time. Thus, the get_request() fails when there is
no existing queue, typically when it's called for the first I/O request of the
process to the device.
Though it will be followed by get_request_wait() for general case,
__make_request() will just end the I/O with an error (EWOULDBLOCK) when the
request was for read-ahead.

This fixed a problem that showed up in the Fedora development tree a few
weeks before the Fedora Core 4 release, initially as slab corruption, later
as hard crashes on boot up, when slab debugging was disabled for the
release. More details on the history at
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=158424
The problem is caused by sbp2's use of scsi_host->hostdata[0] to hold a
scsi_id, without explicitly requesting space for it. Since hostdata is
declared as a zero-sized array, we don't get any such space by default, so
it must be explicitly requested. The patch below implements just that.

On 64-bit machines, PCI_BASE_ADDRESS_MEM_MASK and other mask constants
passed to pci_size() are 64-bit (for example ~0x0fUL). However, pci_size
does comparisons between the u32 arguments and the mask, which will fail
even though any result from pci_size is still just 32-bit.
Changing the mask argument to u32 seems the obvious thing to do, since all
arithmetic in the function is 32-bit and having a larger mask makes no
sense.
This triggered on a PPC64 system here where an adapter (VGA, as it
happened) had a memory region base of 0xfe000000 and a sz of the same,
matching the if (max == maxbase ...) test at the bottom of pci_size but
failing the mask comparison. Quite a corner case which I guess explains
why we haven't seen it until now.

Despite all the care lately in making the powermac sleep/wakeup as
robust as possible, there is still a nasty related to the use of cpufreq
on PMU based machines. Unfortunately, it affects paulus old powerbook
so I have to fix it :)
We didn't manage to understand what is precisely going on, it leads to
memory corruption and might have to do with RAM not beeing properly
refreshed when a cpufreq transition is done right before the sleep.
The best workaround (and less intrusive at this point) we could come up
with is included in this patch. We basically do _not_ force a switch to
high speed on suspend anymore (that is what is causing the problem) on
those machines. We still force a speed switch on wakeup (since we don't
know what speed we are coming back from sleep at, and that seems to work
fine).
Since, during this short interval, the actual CPU speed might be
incorrect, we also hack around by multiplying loops_per_jiffy by 2 (max
speed factor on those machines) during early wakeup stage to make sure
udelay's during that time aren't too short.
For after 2.6.12, we'll change udelay implementation to use the CPU
timebase (which is always constant) instead like we do on ppc64 and thus
get rid of all those problems.

My patch from a few weeks back (now in mainline), called "Cleanup skbs to
prevent unregister_netdevice() hanging", can cause our TX timeout code to
fire on machines with lots of VLANs (because it takes > 2 seconds between
when we stop the queues and when we're finished stopping the connections).
When that happens the TX timeout code freaks out and does a WARN_ON()
because as far as it's concerned there shouldn't be a TX timeout happening,
which is fair enough.
I have a "proper" fix for this, which is to a) do refcounting on
connections and b) implement a proper ack timer so we don't keep unacked
skbs lying around for ever. But for 2.6.12 I propose just supressing the
WARN_ON(). Users will still see the "NETDEV WATCHDOG" warning, but that's
not nearly as bad as a WARN_ON() which users interpret as an Oops.

ftdi_sio: Avoid losing bytes at tty-ldisc.
This patch was originally developed by Daniel Smertnig. I
(Ian Abbott) made a few changes. It has been tested by both
Daniel and I, at least for raw, non-canonical receive data
processing.
Here is Daniel's original description of the patch:
===
During a project in which I was using a FTDI 232BM to
transmit data at relative high speeds (625kBit/s), I
noticed a problem where data was lost even if flow
control was enabled: The FTDI-Driver receives 512 Bytes
of data over USB at a time, which consists of 8 64-Byte
packets. Subtracting the 2 bytes of status information
included in each packet this gives 496 "real" data
bytes per read.
This data is passed (indirectly, via the flip buffers)
to the tty line discipline which takes care of
throttling when there the free buffer space reaches
TTY_THRESHOLD_THROTTLE (128). Because the FTDI driver
processes up to 496 bytes at a time, throttling won't
happen in time and the line discipline will discard the
remaining bytes.
To avoid this the patch passes data in 62-byte blocks
to the tty layer and checks the available space in the
ldisc-buffers. If there isn't enough free space,
processing the rest of the data is delayed using a
workqueue.
Note: The original problem should be easily
reproducible with a userspace program which does slow &
small reads.

[AGPGART] Replace check_bridge_mode() with (bridge->mode & AGSTAT_MODE_3_0).
As mentioned earlier, the current check_bridge_mode() code assumes
that AGP bridges are PCI devices. This isn't always true. Definitely
not for HP zx1 chipset and the same seems to be the case for SGI's AGP
bridge.
The patch below fixes the problem by picking up the AGP_MODE_3_0 bit
from bridge->mode. I feel like I may be missing something, since I
can't see any reason why check_bridge_mode() wasn't doing that in the
first place. According to the AGP 3.0 specs, the AGP_MODE_3_0 bit is
determined during the hardware reset and cannot be changed, so it
seems to me it should be safe to pick it up from bridge->mode.
With the patch applied, I can definitely use AGP acceleration both
with AGP 2.0 and AGP 3.0 (one with an Nvidia card, the other with an
ATI FireGL card).
Unless someone spots a problem, please apply this patch so 3d
acceleration can work on zx1 boxes again.
This makes AGP work again on machines with an AGP bridge that isn't a
PCI device.
