Useful for testing hotplug issues with pci drivers.

Added needed release function, now all pci hotplug drivers need to implement
it...

 - Combine pci_alloc_primary_bus_parented into pci_scan_bus_parented.
 - Move the EXPORT_SYMBOL for pci_root_buses up to its definition.
 - Don't EXPORT_SYMBOL pci_scan_bus since it's a static inline.
 - Add the pci_domain_nr() to the sysfs name for this bus.

I noticed we have a couple of redundancies in drivers/pci/Makefile,
have a patch...

Update the PCI Documentation to reflect some of the functions which have
recently been added and removed.

I think it's too long ... so unless anyone has a better idea, I'm going with
pci_acpi_scan_root().  Here's the patch, presented in patch -p1 format to
make greg's scripts happy ;-)

ia64 needs to be passed the pci domain and the acpi handle corresponding
to each root bus.  Rather than change pcibios_scan_root to take additional
arguments, this patch introduces pci_acpi_scan_root().

The following patch fix compilation of drivers/char/ip2main.c. It was
broken by the removal of pci_present().

It just adds open and closing braces around the code that declares the
pci_dev_i variable. The rest of the patch just change the indentation.

The current local APIC code refuses to enable the local APIC
on a P4 if the BIOS booted us with the local APIC disabled.
This patch removes this unnecessary restriction. Please apply.

Most P4 machines do boot with the local APIC enabled, but
Keith Owens reported that the P4 based Compaq Evo N800v
disables the local APIC, even though the machine actually
works if Linux enables it.

It is possible that some P4 machines with broken BIOSen
were saved by our refusal to enable the local APIC. We
can handle them via the DMI blacklist rules instead.

Noticed by Adrian Bunk.

 From -mm tree, fixes oops when removing ide drivers.

The old calculations BUGed on 64k PAGESIZE machines.

The amount of free space is calculated wrongly so
nfsv3 readdir replies are shorted than they could be.

Cleaning of the export caches is currently done by idle
nfsd threads which isn't very reliable.

This patch makes use of work_queues to do it all inside
cache.c

The /proc/net/rpc/*/content files now will show
entries that are still in the cache, but are either
expired or negative, as comment.

ip_map_show is enhance to work if called with a negative
or incomplete entry.

Also if cache debugging is enabled, the expiry time and
refcount of each entry will be included in a comment.

The sunrpc/cache.c caches which store nfsd export information
can be updated either "inplace" or by replacing the entry.

replacement is needed when an entry hold a reference to some
other object, so the reference counts work properly.

"inplace" can be used when no such references are held, and should be
used when the object could be refered to by another cache (as otherwise
the other cache would have to be updated whenever this one is).

Previously the type of update (inplace or replace) was specified
as an argument to the *_lookup operation.  This too easily lead to
inconsistancies.

With this patch, the update mode is specified when the cache is
declared.

..as the update might have set an expiry date in the past
and we want it to be removed instantly.

Having a 'continue' at the end of this look it pointless... it should
be a break.

- add buggy_uart parameter
- use detected Vcc values, not CIS Vcc values
- handle OxSemi OXCF950 ports

Remove the work queue for serial_remove; events always happen
in process context now so the work queue gains us nothing.

If one turns off SERIAL_8250, these items shouldn't be selectable.
Also gets the indentation right in `make oldconfig'.

- PCI API init style conversion for drivers/net/sk98lin/skge.c;
- new helpers: SkGeDev{Init/CleanUp};
- sk_devs_lock moved around as it's needed early.

Compiles without error. Untested.
