- Two tweaks to the pseudo-MDLM support:

* ignore a padding bit that doesn't seem necessary
- Remove ID for one Motorola phone that uses the MDLM stuff.

ioctl_by_bdev may only be used INSIDE the kernel. If the "arg" argument
refers to memory that is accessed by put_user/get_user in the ioctl
function, the memory needs to be in the kernel address space (that's the
set_fs(KERNEL_DS) doing in the ioctl_by_bdev). This works on i386 because
even with set_fs(KERNEL_DS) the user space memory is still accessible with
put_user/get_user. That is not true for s390. In short the ioctl
implementation of the pktcdvd device driver is horribly broken.

[Patch] Fix raw device ioctl pass-through
Raw character devices are supposed to pass ioctls through to the block
devices they are bound to. Unfortunately, they are using the wrong
function for this: ioctl_by_bdev(), instead of blkdev_ioctl().
ioctl_by_bdev() performs a set_fs(KERNEL_DS) before calling the ioctl,
redirecting the user-space buffer access to the kernel address space.
This is, needless to say, a bad thing.
This was noticed first on s390, where raw IO was non-functioning. The
s390 driver config does not actually allow raw IO to be enabled, which
was the first part of the problem. Secondly, the s390 kernel address
space is distinct from user, causing legal raw ioctls to fail. I've
reproduced this on a kernel built with 4G:4G split on x86, which fails
in the same way (-EFAULT if the address does not exist kernel-side;
returns success without actually populating the user buffer if it does.)
The patch below fixes both the config and address-space problems. It's
based closely on a patch by Jan Glauber <jang@de.ibm.com>, which has
been tested on s390 at IBM. I've tested it on x86 4G:4G (split address
space) and x86_64 (common address space).
Kernel-address-space access has been assigned CAN-2005-1264.

This has been a problem for me for ages. When using bridging, the driver
is switched into promiscuous mode before the link init is complete. The
init complete routine then resets the promisc bit on the card so the kernel
still thinks the card is in promiscuous mode but the card isn't. doh.
I think this bug only shows up in bridging when the bridge is started at
boot time (or something else that sets promisc at the same time the card
was started). If promisc is enabled later it works.
Here's a trivial (and hopefully correct) patch that works for me. It
just calls the promisc/multicast setup routine after init.

Some of them have consequences that aren't documented well.
For example, turning off TCP timestamps risks data corruption from sequence wrap.
A new driver shouldn't need so may #ifdef's unless you want to putit on older
vendor versions of 2.4
Some accessor and wrapper functions like:
t1_pci_read_config_4
adapter_name
t1_malloc
are just annoying noise.
Why have useless dead code like:
/* Interrupt handler */
+static int pm3393_interrupt_handler(struct cmac *cmac)

+ u32 master_intr_status;
+/*
+ 1. Read master interrupt register.

Problem:
During the libata CD-ROM stress test, sometimes the "BUG: timeout
without command" error is seen.
Root cause:
Unexpected interrupt occurs after the ata_qc_complete() is called,
but before the SCSI error handler. The interrupt handler is invoked
before the SCSI error handler, and it clears the command by calling
ata_qc_complete() again. Later when the SCSI error handler is run,
the ata_queued_cmd is already gone, causing the "BUG: timeout without
command" error.
Changes:
- Use the ATA_QCFLAG_ACTIVE flag to prevent the interrupt handler
from completing the command twice, before the scsi_error_handler.

This patch brings the airo driver into line with the current
WEXT specification of signal quality. It also fixes the values
used to determine signal quality and level for MPI & PCMCIA 350
cards. It turns out that BSSListRid.rssi was actually in dBm
for 350 series cards, and that we can use the normalized
signal strength reported by the card as our "quality" value, on
a scale of 0 - 100. Since signal level values are in dBm for
this driver, max_qual->level MUST be 0, as specified in the WEXT
spec. This patch also uses the IW_QUAL constants new in WEXT
version 17.

I've got a pair of FA312 cards and this problem has bothered me

Turns out that somebody wasn't following the documentation. We were
