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

From: Joel Schopp <jschopp@austin.ibm.com>

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.

Add smt_snooze_delay cpu sysfs attribute

Oops cleanup:

- Move prototypes into system.h
- Move the debugger hooks into die, all the calls sites were calling them.
- Handle bad values passed to prregs

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.

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

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.

The JS20 uses devfn 0 for a HT->PCI bridge.  The PHB devfn
assumption does not hold for this case.

From: Jake Moilanen <moilanen@austin.ibm.com>

Allow PCI devices to use address that happens to fall in the ISA range,
but still protect against ISA device accesses when there is not an ISA
bus.
