David Sterba a51f4124e6 ipwireless: fix potential tty == NULL dereference

			IPW_CONTROL_LINE_DCD) != 0
		&& ipwireless_tty_is_modem(tty)) {

Paul Mundt 9170d2f6e1 pcmcia: ipwireless depends on NETDEVICES
ipwireless (added by 099dc4fb62) is clearly
a net device:

drivers/built-in.o: In function `ipwireless_ppp_start_xmit':
/home/pmundt/devel/git/sh-2.6.25/drivers/char/pcmcia/ipwireless/network.c:165: undefined reference to `skb_under_panic'
/home/pmundt/devel/git/sh-2.6.25/drivers/char/pcmcia/ipwireless/network.c:165: undefined reference to `kfree_skb'
drivers/built-in.o: In function `ipwireless_network_packet_received':
/home/pmundt/devel/git/sh-2.6.25/drivers/char/pcmcia/ipwireless/network.c:377: undefined reference to `__alloc_skb'
/home/pmundt/devel/git/sh-2.6.25/drivers/char/pcmcia/ipwireless/network.c:377: undefined reference to `skb_over_panic'
drivers/built-in.o: In function `ppp_shutdown_interface':
/home/pmundt/devel/git/sh-2.6.25/drivers/net/ppp_generic.c:2517: undefined reference to `unregister_netdev'
/home/pmundt/devel/git/sh-2.6.25/drivers/net/ppp_generic.c:2517: undefined reference to `free_netdev'
[ ... and many more ... ]

select strikes again. ipwireless selects PPP which in turn tries to select
SLHC, both of which are technically "protected" by an if NETDEVICES
in drivers/net/Kconfig. This leads to .config hilarity, with net suddenly
ending up in the SCSI menu:

	#
	# SCSI device support
	#
	# CONFIG_SCSI_DMA is not set
	# CONFIG_SCSI_NETLINK is not set
	CONFIG_PPP=y
	# CONFIG_PHONE is not set

Curiously the SLHC select from PPP doesn't seem to happen, as there's no
CONFIG_SLHC=y (only CONFIG_PPP=y gets set) -- Kconfig bug? Caught with a
randconfig.

David Sterba 099dc4fb62 ipwireless: driver for PC Card 3G/UMTS modem
The device is manufactured by IPWireless.  In some countries (for
example Czech Republic, T-Mobile ISP) this card is shipped for service
called UMTS 4G.

It's a piece of PCMCIA "4G" UMTS PPP networking hardware that presents
itself as a serial character device (i.e.  looks like usual modem to
userspace, accepts AT commands, etc).

Olof Johansson ecb8a8472f pcmcia: convert some internal-only ioaddr_t to unsigned int
Convert the io_req_t members to unsigned int, to allow use on machines with
more than 16 bits worth of IO ports (i.e.  secondary busses on ppc64, etc).

There was only a couple of places in drivers where a change was needed.  I
left printk formats alone (there are lots of %04x-style formats in there),
mostly to not change the format on the platforms that only have 16-bit io
addresses, but also because the padding doesn't really add all that much value
most of the time.

I found only one sprintf of an address, and upsized the string accordingly (I
doubt anyone will have anywhere near INT_MAX as irq value, but at least
there's room for it now).

Pascal Terjan ddd73611b7 cm40x0_cs.c: fix debug macros
When PCMCIA_DEBUG is set, cm40x0_cs.c and cm4000_cs.c don't build because the
definition of reader_to_dev uses a non-existent handle field of the struct
pcmcia_device in the call to handle_to_dev.  As handle_to_dev works on struct
pcmcia_device, the fix is quite trivial.

Jean Delvare 6473d160b4 PCI: Cleanup the includes of <linux/pci.h>
I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.

In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.

My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:

arch/alpha/kernel/err_common.c

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.

Marcel Holtmann 059819a41d [PATCH] Fix buffer overflow in Omnikey CardMan 4040 driver (CVE-2007-0005)
Based on a patch from Don Howard <dhoward@redhat.com>

When calling write() with a buffer larger than 512 bytes, the
driver's write buffer overflows, allowing to overwrite the EIP and
execute arbitrary code with kernel privileges.

In read(), there exists a similar problem, but coming from the device.
A malicous or buggy device sending more than 512 bytes can overflow
of the driver's read buffer, with the same effects as above.

Alan Cox 606d099cdd [PATCH] tty: switch to ktermios
This is the grungy swap all the occurrences in the right places patch that
goes with the updates.  At this point we have the same functionality as
before (except that sgttyb() returns speeds not zero) and are ready to
begin turning new stuff on providing nobody reports lots of bugs

If you are a tty driver author converting an out of tree driver the only
impact should be termios->ktermios name changes for the speed/property
setting functions from your upper layers.

If you are implementing your own TCGETS function before then your driver
was broken already and its about to get a whole lot more painful for you so
please fix it 8)

Also fill in c_ispeed/ospeed on init for most devices, although the current
code will do this for you anyway but I'd like eventually to lose that extra
paranoia
