Minor cleanup: don't call pci_update_resource() for bridges,
get rid of bogus "trying to set non-standard region" messages thus.

Patch from Ivan Kokshaysky

This fixes long standing typo ('size' instead of 'r_size') which causes
overestimate of the bridge memory ranges calculated in pbus_size_mem().
For example, if we have a device with one 1Mb and one 2Mb memory ranges
behind the bridge, calculated size and alignment of the bridge memory
window will be 4Mb and 2Mb respectively, while the correct values are
3Mb and 1Mb.

In an attempt to "unuse" pci_do_scan_bus() so it can be eventually
killed, make pci_scan_bus_parented() call the new pci_scan_child_bus()
and pci_bus_add_devices().  The only remaining callers are the
hotplug drivers.

Eventually, pci_bus_add_devices() will be removed from this function -
it is intended that architectures should call this after they have
done any setups and fixups to the scanned bus.

It is legal to call pci_bus_add_devices() on a bus which has already
had this function called, so architectures could update today.

Pull out the bits of cardbus configuration - the secondary latency
timer, and the number of bus numbers we reserve.

pci_read_config_dword() takes a u32 pointer, not unsigned long.

Miscellaneous cleanups to probe.c:
        - make code/comments wrap before column 80.
        - remove extraneous space.

Kill pcibios_update_resource(), replacing it with pci_update_resource().
pci_update_resource() uses pcibios_resource_to_bus() to convert a
resource to a device BAR - the transformation should be exactly the
same as the transformation used for the PCI bridges.

pci_update_resource "knows" about 64-bit BARs, but doesn't attempt to
set the high 32-bits to anything non-zero - currently no architecture
attempts to do something different.  If anyone cares, please fix; I'm
going to reflect current behaviour for the time being.

Ivan pointed out the following architectures need to examine their
pcibios_update_resource() implementation - they should make sure that
this new implementation does the right thing.  #warning's have been
added where appropriate.

	ia64
	mips
	mips64

This cset also includes a fix for the problem reported by AKPM where
64-bit arch compilers complain about the resource mask being placed
in a u32.

Convert pcibios_fixup_pbus_ranges() into something more generic, namely
pcibios_resource_to_bus() - we are really trying to convert resources
to something to program into bus registers for bridge windows, and in
fact, PCI device BARs.

This is necessary since some architectures, namely Alpha, ARM and PARISC
have an offset between PCI addressing and host-based addressing, so
resources need to be adjusted when read or when written back to the bus.

We provide a generic version in asm-generic/pci.h, which most
architectures use.

This patch finds the following architectures with something to think
consider:

        - ppc, ppc64
                adjusts resources for devices, but not buses.
		This is inconsistent, and leads to improperly
		programmed windows/BARs.

PPC people (Anton) has a replacement PCI resource implementation
which should do the right thing.

Patch from Ivan Kokshaysky

remove the "parent" or "root" second argument to
pcibios_update_resource().  This highlights the following
architectures doing something wrong in their implementation:

        - ia64
        - mips it8172
        - mips "generic mips boards"
        - mips64 "generic mips boards"
        - mips64 IP27

Fix breakage in pci-3 - we scanned all functions if function 0 was not
present.  This causes some host bridges to lock up when scanning devfn
255 on PPC machines.

No code changes; still builds OK.

This is Robert PJ Day's patch that updates the filesystems
config menu.  It had become a bit ad hoc (jumbled:) and this
patch attempts to arrange it more logically.

This adds the gtk front end by Romain Liévin <roms@tilp.info>

This adds the support for the menuconfig to the front ends.
qconf also has now an ".." entry to make it more obvious
how to get to a parent menu.

This adds the support for the menuconfig keyword, which allows to define
a config symbol and a submenu with a single step, e.g. instead of

	menu "SCSI device support"

	config SCSI
		tristate "SCSI device support"

this is now enough:

	menuconfig SCSI
		tristate "SCSI device support"

A menu entry was possibly inserted to high in the menu hierarchie if
the previous entry was a derived config symbol.

This restores the old config behaviour for dependencies on 'm',
such entries are only activ if CONFIG_MODULES is enabled as well.

Register the tty devclass with sysfs before tty drivers initialise -
sysfs requires structures to be registered before use.  This is
required for the previous serial csets, as well as any drivers which
are initialising using __initcall() or module_init().

There was one place where we missed an unlock, in addition some more
code cleanups.
