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.

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.

Disable SMT snooze by default

From: Olof Johansson <olof@austin.ibm.com>

RTAS on IBM pSeries runs in real mode, so all pointers being passed in to
it need to be in low memory.  There's two places in the RAS code that
passes in pointers to items on the stack, which might end up being above
the limit.

Below patch resolves this by creating a buffer in BSS + a lock for
serialization.  There's no reason to worry about contention on the lock,
since rtas_call() also serializes on a single spinlock and this is an
infrequent code path in the first place.

From: David Gibson <david@gibson.dropbear.id.au>

On PPC64, to deal with the restrictions imposed by the PPC MMU's segment
design, hugepages are only allowed to be mapping in two fixed address
ranges, one 2-3G (for use by 32-bit processes) and one 1-1.5T (for use in
64-bit processes).  This is quite limiting, particularly for 32-bit
processes which want to use a lot of large page memory.

This patch relaxes this restriction, and allows any of the low 16 segments
(i.e.  those below 4G) to be individually switched over to allow hugepage
mappings (provided the segment does not already have any normal page
mappings).  The 1-1.5T fixed range for 64-bit processes remains.

This is the iSeries virtual ethernet driver.  David Gibson has taken you
previous comments and hopefully sitisfied most of them.  The driver has
also undergone some more testing which showed up some bugs which have been
addressed.

Unfortunately, Anton is about to submit some other patches of mine which
will sightly comflict with this.  I will send a patch shortly that will
(hopefully) fix that.
