Should have been in earlier changeset. D'oh.

Split out all system device definitions from device.h into their own header
sysdev.h

Define struct sysdev_attribute and define functions to export attributes 
in sysfs. 

- Suspend system devices last, after interrupts have been enabled. 
- Resume them first, before interrupts are enabled. 
- Shut them down last, after everything else.

Shorthand macro for initializing only the name of an embedded kset in an 
object.

System devices are special, and after two years of listening to Linus
preach this, it finally sunk in enough to do something about. We don't
need to regard them as real devices that reside on a peripheral bus and
can be dynamically bound to drivers. If we discover, e.g. a CPU, we know
by default that we have a driver for it, and we know damn well that we
have a CPU. We still need to keep track of all the devices, and all the
devices of a particular type. The kobject infrastructure allows us to do
this, without the overhead of the regular model.

A new subsystem is defined that registers as a child object of 
devices_subsys, giving us:

        /sys/devices/system/

struct sysdev_class {
        struct list_head        drivers;

        /* Default operations for these types of devices */
        int     (*shutdown)(struct sys_device *);
        int     (*suspend)(struct sys_device *, u32 state);
        int     (*resume)(struct sys_device *);
        struct kset             kset;
};

Defines a type of system device. These are registered on startup, by e.g. 
drivers/base/cpu.c. The methods are default operations for devices of that 
type that may or may not be used. For things like the i8259 controller, 
these will be filled in, since it is registered by the same component that 
the device controls reside in. 

For things like CPUs, generic code will register the class, but other 
architecture-specific or otherwise configurable drivers may register 
auxillary drivers, that look like: 

struct sysdev_driver {
        struct list_head        entry;
        int     (*add)(struct sys_device *);
        int     (*remove)(struct sys_device *);
        int     (*shutdown)(struct sys_device *);
        int     (*suspend)(struct sys_device *, u32 state);
        int     (*resume)(struct sys_device *);
};


Each auxillary driver gets called during each operation on a device of a 
particular class. 
Auxillary drivers may register with a NULL class parameter, in which case 
they will be added to a list of 'global drivers' that get called for each 
device of each class. 


Besides providing a decent of cleanup for system device drivers, this also 
allows:

- Special handling of system devices during power transitions. 

  We no longer have to worry about shutting down the PIC before we shut 
  down any devices. We can shut down the system devices after we've shut 
  down every other device. 

  Ditto for suspend/resume cycles. Almost (if not) all PM actions for 
  system devices happen with interrupts off, and require only one call, 
  which makes that easier. But, we can also make sure we take care of 
  these last during suspend and first during resume.

- Easy expression of configurable device-specific interfaces. 

  Namely cpufreq and mtrr. We don't have to worry about mispresentation in 
  the driver model (like recent MTRR patches) or using a cumbersome 
  interface ({device,class}_interface) that don't receive all the 
  necessary calls. 

- Consolidation of userspace representation.

  No longer do we have /sys/devices/sys, /sys/bus/sys, and /sys/class/cpu,
  etc. We have only /sys/devices/system: 

# tree /sys/devices/system/
/sys/devices/system/
|-- cpu
|   `-- cpu0
|-- i8259
|   `-- i82590
|-- lapic
|   `-- lapic0
|-- rtc
|   `-- rtc0
`-- timer
    `-- timer0

Each directory in 'system' is the class, and each directory under that is 
the instance of each device in that class.

dev_ioctl already checks capable(CAP_NET_ADMIN) for SOICETHTOOL, so
privileged reference are not necessary.

Add 10GbE support for ethtool.

This one should be safe as we're protected by the xmit_lock in all instances

Attached is a driver for Atmel at76c50x WiFi cards. This code started
out as a GPL release from Atmel of pretty horrible quality and I've
extensively re-worked it with the aim of making it acceptable in the
kernel. Please could you take a look and either pass it into the patch
stream or let me know what's wrong with it?

The code has been tested on at least three different brand cards by
different people. Jean Tourrilhes took a look at an earlier version an
was positive. He's put incorporating this into 2.6 as a priority 1.
The patch works fine on 2.5.70.

The firmware issue has been addressed now. The only firmware in the
driver is a small stub which reads the MAC address from NVRAM on the
card. The source for that is included so there are no GPL issues. The
main firmware is loaded from userspace using Manuel Estrada Sainz's
sysfs firmware class. I know that the  patch for that has been
accepted but it hasn't turned up anywhere I can see yet. The 
driver compiles fine even without the firmware class. I've made a
package of the firmware images which is available from my website.

The remaining issues with the driver are migrating PCMCIA to the new
driver model and PCI support. I'm happy to produce followup patches as
the PCMCIA system gets evolved to the new driver model: the timing on
that is controlled by others. This set of chips includes a PCI version
and the driver should support that, but AFAIK there is no PCI hardware
available anywhere. If Atmel can provide me with some it will be
simple to add PCI support.

The driver uses the CRC32 library module and the firmware loader. I've
not put in dependencies on those, but when the lastest set of patches
go into Kconfig I'll set it up so that selecting the Atmel driver
selects CRC32 and FW_LOADER too.

Inspecting the sb1000 driver showed some interesting bugs:
	- net device pointer is used before the device is allocated; gcc
	  does catch this.
	- unregister is called even though device not registered successfully
	- net device is not freed on remove.

Compiles but don't have hardware to test.  Don't know how it ever worked though.

Two ioctl functions in sound/oss/awe_wave.c were directly dereferencing
a user-supplied pointer in a few places.

Jörn missed a few places of FAR conversion in inflate

Remove the stale support for K&R function declarations through the OF()
macro.

This is the last patch to clean up zconf.h, at least for now.

This nice macro must have been one of the good intentions on the road
to hell.  Completely unused. :)

Just a simple s/ZEXPORT//.

This one was just simple s/ZEXTERN/extern/g.

Remove unused __32BIT__ and STDC macros

This removes FAR, the typedefs using FAR (Bytef and friends) and the
function prototypes for zalloc and zfree that should have gone earlier
already.

What happens when you get a patch that does something an applied patch 
already does, but a little better, and merge it sloppily: You end up calling
the wrong function because you've defined equivalent methods in two places.

Bad Pat, Bad.
