OK, the grand finale ... NUMA-Q is now moved into subarch, so we can
kill off the last vestiges - CONFIG_CLUSTERED_APIC, clustered_apic_mode,
and smpboot.h (which only contains machine specific stuff now anyway).
the esr_disable switch was the last bit, that goes to subarch too.

If you end up with an empty smpboot.h due to patch / bitkeeper interactions,
please remove it after this ...

This removes clustered_apic_mode from smpboot.c into subarch,
creating a headerfile "mach_wakecpu" for all the cpu wakeup stuff.
This is pretty much the last of clustered_apic_mode ... ;-)

To be honest, I have no idea what I was smoking when I wrote this
originally, and it's kind of coincidental that it works at all currently.

We never use physical apicids after the cpus are all booted, so we should
just store the logical IDs which all subsequent things use. The only things
that were using the apicid->cpu mapping were hokey anyway, and it's hard to
maintain for machines that have a large apic addressing space (eg P4s
in clustered mode). Rips out everything except the mapping from
logical_apic_id -> cpu.

Moves check_phys_apicid_present() into subarch, and cleans up a
couple of stupid errors, and some bracketing issues in the macros.

Patch from James Cleverdon

Changes do_boot_cpu to return an error code, instead of trying to
work it out later by magic and voodoo. Removes the other usage
of apicid->cpu which is hard to maintain cleanly.

Patch originally by Matt Dobson. Reworked a little by me.

Stores the mappings between cpus and nodes in an array, instead of
working them out every time. Gives about 4% off systime for kernel
compile (we use these for every page allocation), and removes one
of the two only usages of apicid->cpu mapping, which is really awkward
to keep for systems with large apic spaces, and is genererally pretty
useless anyway (later patch removes).

Create a generalised apicid_to_node mapping, replacing the local
apicid_to_quad I had just locally in NUMA-Q subarch before.

This simply uses generic_file_aio_read and generic_file_aio_write

Make x86-64 compile again after recent extable changes.

Micheal Meeks notes:

	"Evolution is non-functioning on recent 2.5.X kernels, due to
    mal-performance in getpeername => net/unix/af_unix.c (unix_getname),
    where it seems we switch 'sk' on 'peer', but not the (previously)
    typecast pointer to it; this fixes it."

and stop honoring the SA_RESTORER information.

This will prepare us for alternate signal handler returns.

Simply, pass off to kset_find_obj() to iterate over list of buses and 
search for bus with certain name.

The operation is simple:
- Take read lock for kset.
- Iterate over kset->list.
- Compare name to each kobject's name.
- Return kobject if found. 

This creates and exports device_bind_driver() and device_release_driver()
that allow a caller to manually bind a device to a driver. Apparantly, some
drivers use this functionality (like USB): a driver binds to other device
interfaces during the driver's probe() method call for the first interface.

Implementation is easy enough, since it simply involves renaming and exporting
the internal functions attach() and detach().

In drivers/base/bus.c, get_bus() was called without put_bus() in these 
functions:

- bus_for_each_dev()
- bus_for_each_drv()

This is in preparation for sync_fs super_operation.

- declare net_subsys, and register during net_dev_init().
- Add kobject to struct net_device.
- initialize name and register in register_netdevice().
- remove in unregister_netdevice().

This allows one to see the registered network devices in the system via:

# tree /sys/net/
/sys/net/
`-- eth0

Here are the i810 and i830 fixes.  I don't have either of these, so I
can't test them, but they're pretty straightforward.

I don't have a 440GX to test here, but I think the patch below is likely
to fix the problem.

I see some other issues in intel-agp.c.  I'll send those separately since
the diff is a little larger and should affect only i810 and i830.

Since block_subsys already contains a list and a lock, use those, instead
of defining our own static ones.

This allows struct gendisk::full_list to be removed. 

struct gendisk::list is also apparently unused, so it is removed also.

This was never used, and a bad idea to begin with. 

The kobject core no longer references a subsystem directly through a kobject,
instead using the kobject's dominant kset to reference the subsystem. The 
registrants of kobjects have been fixed up. 

To aid in this process, a few helpers were introdcuced: 

- kobj_set_kset_s(obj,subsys)
- kset_set_kset_s(obj,subsys)
- subsys_set_kset(obj,subsys)

that set the kset ptr of embedded kobjects for objects that have different
embedded types. See include/linux/kobject.h for more description and usage.


struct subsystem::kobj is also removed, relying solely on a subsystem's
embedded kset for hierarchy information.  Since this requires modification
of the subsystem declarations, a helper macro has been defined:

decl_subsys(name,type)

which initializes the name and ktype fields of the subsystem's embedded
kset. All the subsystem declarations have been fixed up.

Various archs (i386, m68k, s390, s390x, m68k, parisc, um, x86_64)
implement kernel_text_address.  Put this in kernel/extable.c, and the
module iteration inside module.c.

Other than cleanliness, this finally allows the module list and lock
to be static to kernel/module.c (you didn't think I actually cared
about those archs did you?)

It also drops the module->init_size to zero when it's discarded, so
bounds checking is simplified (and the /proc/modules size statistic
will be more accurate, too).

The declaration of `module_frob_arch_sections' in moduleloader.h (and
the definitions in most of the module.c files) are inconsistent with the
definition in the PPC's module.c -- in the latter the first two
arguments are not declared `const', whereas everyplace else they are.

PS.  secstrings can be modded to: if an arch can't handle discarding
     init, it simply renames the .init sections.
