ISOFS to use export_operations to declare exportability

Exporting ISO's has never been very reliable
as lookup("..") doesn't work (even though there is
some code that tries to pretend that it does).

This means that if an inode falls out of cache, any
filehandle on it will become stale.

This makes that level of support explicit with an empty
export_operations structure.  get_parent could be written....
but not today.

Basically PCI driver handling reorganization. This is one step further
ahead toward the goal of fully modularized host chip drivers.

 - Adjust ide-scsi to the new error handling. Just don't try any device
   resets there.

 - Add unmasking of IRQ per default to the PMac PCI code.

 - Split up the crap table from ide-pci. Let the corresponding drivers do
   registration of the functions they provide. This small change makes
   this patch rather big.

 - Hard-code the number of ports requested for DMA engines. They are always
   precisely 8 on PCs. If you hove something different to deal with,
   well then please just provide your own init_dma method.

 - Remove the HDIO_GETGEO_BIG ioctl. Patch by Andries Brouwer. Applies
   unmodified.

 - Make ON_BOARD be equal 0, so we can spare ourself some typing in structure
   initialization.

 - Normalize the terminology in the host chip drivers. It will make spotting
   the tons of common code found there later easier.

removed pcihpfs_statfs(), as it's not used anymore.

update the ibm pci hotplug driver to the latest version.  Contains lots of
small bugfixes and added features for new hardware.

This adds support for recent powermac models and fixes a few bugs.

and also streamlines the exception entry/exit code by not saving
all the GPRs on the common exceptions (system call, external
interrupt and decrementer).

This patch fixes directory notification so that notifications get
cancelled when a process exits.  This make dnotify MUCH more stable and
usable :-)

On 32-bit PPC we don't need setup-bus.o but we do need setup-irq.o.
This patch changes drivers/pci/Makefile to reflect that.

This patch fixes the compile errors in sd_find_target, which is only
used on 32-bit PPC systems, and changes the ifdef around from
CONFIG_PPC to CONFIG_PPC32 since ppc64 doesn't need this routine.

From 2.4

We weren't incrementing the address when walking a processes
address space.  From 2.4

Found by Andries Brouwer a while back iirc.

Use listwalking macro..

into arch/i386/kernel as they are needed even if CONFIG_PCI is not enabled.

Fix acenic driver

JFS: Flush dirty metadata to disk when remounting from read-write
to read-only.  Also fix umount ordering to make sure metadata is
written before journal closed.

With Andrew Morton's recent changes, JFS is no longer writing much
of its dirty metadata when remounting from read-write to read-only.
This causes severe file system corruption.  A JFS root file system
will be corrupted on shutdown.

This patch fixes the problem by explicitly writing the dirty metadata
before the journal is closed.  It also fixes the ordering so that
the dirty metadata is completely written before the journal is closed
for the normal unmount case as well.
