907293d788 firewire: consistent usage of node_id
Definitions as per IEEE 1212 and IEEE 1394:

     Node ID: Concatenation of bus ID and local ID. 16 bits long.
      Bus ID: Identifies a particular bus within a group of buses
              interconnected by bus bridges.
    Local ID: Identifies a particular node on a bus.
      PHY ID: Local ID of IEEE 1394 nodes. 6 bits long.

Never ever use a variable called node_id for anything else than a node ID.

Instances of struct file_operations and struct fw_card_driver can be
qualified as "const".  Ditto with struct fw_descriptor.data, struct
fw_device_id, and predefined instances of struct fw_address_region,

Data qualified as const is placed into the .rodata section which won't

38f3323037 Revert "[PATCH] LOG2: Alter get_order() so that it can make use of ilog2() on a constant"
This reverts commit 39d61db0ed.

The commit was buggy in multiple ways:
 - the conversion to ilog2() was incorrect to begin with
 - it tested the wrong #defines, so on all architectures but FRV you'd
   never see the bug except for constant arguments.
 - the new "get_order()" macro used its arguments multiple times, and
   didn't even parenthesize them properly
 - despite the comments, it was not true that you could use it for
   constant initializers, since not all architectures even use the
   generic page.h header file.

All of the problems are individually fixable, but it all boils down to:
better just revert it, and re-do it from scratch.

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.

266d4f4037 [PATCH] suspend regression: sysfs deadlock
Suspend deadlocks when trying to unregister /sys/block/sr0.

This comes from Oliver's commit 94bebf4d1b
"Driver core: fix race in sysfs between sysfs_remove_file() and
read()/write()".

sysfs_write_file downs buffer->sem while calling flush_write_buffer, and
flushing that particular write buffer entails downing buffer->sem in
orphan_all_buffers, resulting in the obvious self-deadlock.
