Implementation of new quota format. The code is almost the same
as in -ac versions of kernel. All the code for new format is in
quota_v2.c

Implementation of old quota format. All the code for old format is now in
quota_v1.c. Code mostly remained the same as in older kernels (just minor
changes were needed to bind it with quota interface).

This is probably the largest chunk in quota patches. It removes old quotactl interface
and implements new one. New interface should not need arch specific conversions so they
are removed. All quota interface stuff is moved to quota.c so we can
easily separate things which should be compiled even if quota is disabled (mainly
because XFS needs some interface even if standard VFS quota is disabled).
Callbacks to filesystem on quota_on() and quota_off() are implemented (needed by Ext3),
quota operations callbacks are now set in super.c on superblock initialization and
not on quota_on(). This way it starts to make sense to have callbacks on alloc_space(),
alloc_inode() etc. as filesystem can override them on read_super(). This will be used
later for implementing journalled quota.

This patch implements counting of used space in inodes in bytes.
New field i_bytes is added and used space modulo 512 is kept in
it (rest is still kept in i_blocks). Functions manipulating both
i_blocks and i_bytes are implemented (inode_add_bytes(), inode_sub_bytes()
and inode_set_bytes()). Filesystems allocating only in whole blocks
can safely ignore i_bytes field and continue using i_blocks...

This patch implements accounting of used space in bytes.

  This patch moves reporting of quota statistics from Q_GETSTATS call to
/proc/fs/quota. Also reporting of registered quota formats is added.

  This patch implements list 'quota_formats' with registered quota formats
and functions register_quota_format() and unregister_quota_format() for
manipulating the list.

This patch removes most format dependent code from dquot.c and quota.h
and puts calls of callback functions instead.

  This patch adds dq_dup_ref to struct dquot. Functions altering just usage of
quota take just this duplicated reference, inodes, quotactl() helpers take real
dq_count reference. dqput() blocks if there are some duplicated references and
put reference is last 'real one'. This way is assured that quota IO is not
done from functions altering quota usage (quota structure is written on last dqput()).

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.
