It seems that a merge_bvec_fn needs to be aware of partitioning...  who
would have thought it :-(

The following patch should fix the merge_bvec_fn for both linear and raid0.
We teach linear and raid0 about partitions in the merge_bvec_fn.

->merge_bvec_fn needs to make decisions based on the physical geometry of the
device.  For raid0, it needs to decide if adding the bvec to the bio will
make the bio span two drives.

To do this, it needs to know where the request is (what the sector number is)
in the whole device.

However when called from bio_add_page, bi_sector is the sector number
relative to the current partition, as generic_make_request hasn't been called
yet.

So raid_mergeable_bvec needs to map bio->bi_sector (which is partition
relative) to a bi_sector which is device relative, so it can perform proper
calculations about when chunk boundaries are.

rpcsec_gss supports three security levels:

1.  authentication only: sign the header of each rpc request and response.

2. integrity: sign the header and body of each rpc request and response.

3.  privacy: sign the header and encrypt the body of each rpc request and
   response.

The first 2 are already supported on the client; this adds integrity support
on the server.

Without this compiling auth_gss as module fails.

From: Fred.  We don't do all the utf8 checking we could in the kernel, but we
do some simple checks.  Implement slightly stricter, and probably more
efficient, checking.

It's better than oopsing.

From: Olaf Hering <olh@suse.de>

initramfs can not be used in current 2.6 kernels, the files will never be
executed because prepare_namespace doesn't care about them.  The only way to
workaround that limitation is a root=0:0 cmdline option to force rootfs as
root filesystem.  This will break further booting because rootfs is not the
final root filesystem.

This patch checks for the presence of /init which comes from the cpio archive
(and thats the only way to store files into the rootfs).  This binary/script
has to do all the work of prepare_namespace().

Teach inode.c about list_move().

Change locking rules in quota code to fix lock ordering especially wrt
journal lock.  Also some unnecessary spinlocking is removed.  The locking
changes are mainly: dqptr_sem, dqio_sem are acquired only when transaction is
already started, dqonoff_sem before a transaction is started.  This change
requires some callbacks to ext3 (also implemented in this patch) to start
transaction before the locks are acquired.

Quieten NVRAM driver

I was looking at rtas serialization for reasons I won't go into here.
While wandering through the code I found that two functions were not
properly serialized.  phys_call_rtas and phys_call_rtas_display_status are
the functions.  After looking further they are redundant and not
used anywhere at all.

Oops cleanup:

James Bottomley is right, this was a mistake.  This patch replaces
vio_dma_mapping_error with dma_mapping_error everywhere.

[PATCH] ppc64: change the iSeries virtual device drivers to use the vio infrastructure for DMA mapping

From: Stephen Rothwell <sfr@canb.auug.org.au>

This patch changes the iSeries virtual device drivers to use the
vio infrastructure for DMA mapping instead of the PCI infrastructure.
This is a step along the way to integrating them correctly into the
driver model.

This patch consolidates some of the iommu DMA mapping routines.

This is just a cleanup to use enum dma_data_direction for all APIs
except the pci_dma_ ones (since they are defined generically).

Also make most of the functions in arch/ppc64/kernel/pci_iommu.c
static.

From: Stephen Rothwell <sfr@canb.auug.org.au>

This patch uses enum dma_data_direction for the vio DMA api routines.
This allows us to remove some include of linux/pci.h.

Also missed some pci_dma_mapping_error uses.
