b6c2799dec [PATCH] USB: add ZyXEL vendor/product ID to rtl8150 driver
I just got a "ZyXEL Prestige USB Adapter" that is actually RTL8150
adapter.  Here is the relevant /proc/bus/usb/devices output (after
adding the vendor/product IDs to the driver):

T:  Bus=01 Lev=02 Prnt=02 Port=02 Cnt=02 Dev#=119 Spd=12  MxCh= 0

P:  Vendor=0586 ProdID=401a Rev= 1.00
S:  Manufacturer=ZyXEL
S:  Product=Prestige USB Adapter
S:  SerialNumber=1027
C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=120mA
I:  If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=00 Prot=ff Driver=rtl8150
E:  Ad=81(I) Atr=02(Bulk) MxPS=  64 Ivl=0ms
E:  Ad=02(O) Atr=02(Bulk) MxPS=  64 Ivl=0ms
E:  Ad=83(I) Atr=03(Int.) MxPS=   8 Ivl=1ms

This patch adds the ZyXEL vendor ID to the rtl8150.c driver.  The
device has absolutely no identifying marks on the outside for model
type, just a serial number, and I can't find anything on ZyXEL's
website, so I called the product ID PRODUCT_ID_PRESTIGE to match the
product string.

b2f1b0d464 [PATCH] USB: ipw.c driver fix
The below patch fixes the ipw module in kernel 2.6.17 for me; without
this change it simply does not work at all (all but the first writes are
refused because write_urb_busy is always 1).

This problem was there in 2.6.15 as well, but at that point I used the
(updated) ipw.c, version 0.4, from
http://www.neology.co.za/products/opensource/ipwireless/ which no longer
compiles with 2.6.17. It can be made to after a few changes but
obviously it's easier if the built-in ipw driver works instead of having
to download one from the neology site.

b33488eb5c [PATCH] USB: ipaq.c timing parameters
Adds configurable waiting periods to the ipaq connection code. These are
not needed when the pocketpc device is running normally when plugged in,
but they need extra delays if they are physically connected while
rebooting.

There are two parameters :

* initial_wait : this is the delay before the driver attemts to start the
  connection. This is needed because the pocktpc device takes much
  longer to boot if the driver starts sending control packets too soon.

* connect_retries : this is the number of times the control urb is
  retried before finally giving up. The patch also adds a 1 second delay
  between retries.

I'm not sure if the cases where this patch is useful are general enough
to include this in the kernel.

b512504e56 [PATCH] USB: ipaq.c bugfixes
This patch fixes several problems in the ipaq.c driver with connecting
and disconnecting pocketpc devices:

* The read urb stayed active if the connect failed, causing nullpointer
  dereferences later on.

* If a write failed, the driver continued as if nothing happened. Now it
  handles that case the same way as other usb serial devices (fix by
  Luiz Fernando N. Capitulino <lcapitulino@mandriva.com.br>)

b972b68c39 [PATCH] USB: ehci: fix bogus alteration of a local variable
In a rare and all-but-unused path, the EHCI driver could reuse a variable
in a way that'd make trouble.  Specifically, if the first root hub port
gets an overcurrent event (rare) during a remote wakeup scenario (all but
unused in today's Linux, except for folk working with suspend-to-RAM and
similar sleep states), that would look like a fatal error which would shut
down the controller.  Fix by not reusing that variable.

224654004c [PATCH] USB serial ftdi_sio: Prevent userspace DoS
This patch limits the amount of outstanding 'write' data that can be
queued up for the ftdi_sio driver, to prevent userspace DoS attacks (or
simple accidents) that use up all the system memory by writing lots of
data to the serial port.

The original patch was by Guillaume Autran, who in turn based it on the
same mechanism implemented in the 'visor' driver.  I (Ian Abbott)
re-targeted the patch to the latest sources, fixed a couple of errors,
renamed his new structure members, and updated the implementations of
the 'write_room' and 'chars_in_buffer' methods to take account of the
number of outstanding 'write' bytes.  It seems to work fine, though at
low baud rates it is still possible to queue up an amount of data that
takes an age to shift (a job for another day!).

00d6058ac9 [PATCH] USB serial visor: fix race in open/close
The anti user-DoS mechanism in the USB serial 'visor' driver can fail in
the following way:

visor_open: priv->outstanding_urbs = 0
visor_write: ++priv->outstanding_urbs
visor_close:
visor_open: priv->outstanding_urbs = 0
visor_write_bulk_callback: --priv->outstanding_urbs

So priv->outstanding_urbs ends up as (unsigned long)(-1).  Not good!

I haven't seen this happen with the visor driver as I don't have the
hardware, but I have seen it while testing a patch to implement the same
functionality in the ftdi_sio driver (patch not yet submitted).

The fix is pretty simple: don't reinitialize outstanding_urbs in
visor_open.  (Again, I haven't tested the fix in visor, but I have
tested it in ftdi_sio.)

d14feb5ee4 [PATCH] USB: au1200: EHCI and OHCI fixes
I received an DBAU1200 eval kit from AMD a few days ago and tried to
enable the USB2 port, but the current linux-2.6 GIT did not even
compile with CONFIG_SOC_1200, CONFIG_SOC_AU1X00, CONFIG_USB_EHCI and
CONFIG_USB_OHCI set.
Furthermore, in ehci-hcd.c, platform_driver_register() was called with
an improper argument of type 'struct device_driver *' which of course
ended up in a kernel oops. How could that ever have worked on your
machines?

Anyway, here's a trivial patch that makes the USB subsystem working
on my board for both OHCI and EHCI.
It also removes the /* FIXME use "struct platform_driver" */.

15e0c69436 [PATCH] ide: fix Jmicron support
Prior to 2.6.18rc1 you could install with devices on a JMicron chipset
using the "all-generic-ide" option. As of this kernel the AHCI driver
grabs the controller and rams it into AHCI mode losing the PATA ports
and making CD drives and the like vanish. The all-generic-ide option
fails because the AHCI driver grabbed the PCI device and reconfigured
it.

To fix this three things are needed.

#1 We must put the chip into dual function mode
#2 The AHCI driver must grab only function 0 (already in your rc1 tree)
#3 Something must grab the PATA ports

The attached patch is the minimal risk edition of this. It puts the chip
into dual function mode so that AHCI will grab the SATA ports without
losing the PATA ports. To keep the risk as low as possible the third
patch adds the PCI identifiers for the PATA port and the FN check to the
ide-generic driver. There is a more featured jmicron driver on its way
but that adds risk and the ide-generic support is sufficient to install
and run a system.

The actual chip setup done by the quirk is the precise setup recommended
by the vendor.

(The JMB368 appears only in the ide-generic entry as it has no AHCI so
does not need the quirk)

f6dc8c5b8e [PATCH] Make cpu_relax() imply barrier() on all arches
During the recent discussion of taking 'volatile' off of the spinlock, I
noticed that while most arches #define cpu_relax() such that it implies
barrier(), some arches define cpu_relax() to be empty.

This patch changes the definition of cpu_relax() for frv, h8300, m68knommu,
sh, sh64, v850 and xtensa from an empty while(0) to the compiler barrier().

0f74964627 [PATCH] lockdep: HPET/RTC fix
Joseph Fannin reported that hpet_rtc_interrupt() enables hardirqs
in irq context:

[   25.628000]  [<c014af4e>] trace_hardirqs_on+0xce/0x200
[   25.628000]  [<c036cf21>] _spin_unlock_irq+0x31/0x70
[   25.628000]  [<c0296584>] rtc_get_rtc_time+0x44/0x1a0
[   25.628000]  [<c01198bb>] hpet_rtc_interrupt+0x21b/0x280
[   25.628000]  [<c0161141>] handle_IRQ_event+0x31/0x70
[   25.628000]  [<c0162d37>] handle_edge_irq+0xe7/0x210
[   25.628000]  [<c0106192>] do_IRQ+0x92/0x120
[   25.628000]  [<c0104121>] common_interrupt+0x25/0x2c

the call of rtc_get_rtc_time() is highly suspect. At a minimum we
need the patch below to save/restore hardirq state.

ec572e3f87 [PATCH] msi: Only keep one msi_desc in each slab entry.
It looks like someone confused kmem_cache_create with a different allocator
and was attempting to give it knowledge of how many cache entries there
were.

With the unfortunate result that each slab entry was big enough to hold
every irq.

232ba9dbd6 [PATCH] lockdep: annotate the sysfs i_mutex to be a separate class
sysfs has a different i_mutex lock order behavior for i_mutex than the
other filesystems; sysfs i_mutex is called in many places with subsystem
locks held.  At the same time, many of the VFS locking rules do not apply
to sysfs at all (cross directory rename for example).  To untangle this
mess (which gives false positives in lockdep), we're giving sysfs inodes
their own class for i_mutex.

d579091b43 [PATCH] fix fdset leakage
When found, it is obvious.  nfds calculated when allocating fdsets is
rewritten by calculation of size of fdtable, and when we are unlucky, we
try to free fdsets of wrong size.

Found due to OpenVZ resource management (User Beancounters).
