The very early memory detection patch broke voyager.

This fixes it again.

Fix a bug which was spotted by Alex Lyashkov <shadow@psoft.net>

The fairly unobvious coding in __kill_pg_info() will cause a zero value to be
incorrectly returned if the second or succeeding call to
group_send_sig_info() returns an error.

This patch is needed on s390.

From: James Bottomley <James.Bottomley@SteelEye.com>

pci_dev.consistent_dma_mask was introduced to get around problems in the
IA64 Altix machine.

Now, we have a use for it in x86: the aacraid needs coherent memory in a
31 bit address range (2GB).  Unfortunately, x86 is converted to the dma
model, so it can't see the pci_dev by the time coherent memory is
allocated.

The solution to all of this is to move pci_dev.consistent_dma_mask to
dev.coherent_dma_mask and make x86 use it in the dma_alloc_coherent()
calls.

This should allow me to make the aacraid set the coherent mask instead
of using it's current dma_mask juggling.

We should drop module sem before calling mod->exit, for practical reasons:
too many module exit functions oops or hang, resulting in a permenantly held
module sem, which blocks all module ops including lsmod.

From: "David S. Miller" <davem@redhat.com>

Currently, for an existing DMA mapping, there is a way to transfer buffer
ownership back to the cpu, yet there is no way to give it back to the device
again explicitly.  The latter really is needed on platforms where the PCI
subsystem does not snoop the cpu caches, MIPS is one example.

Many drivers were expecting the existing DMA sync interface to handle both
directions, which was wrong.

Now, with this change, we have explicit interfaces for DMA syncing to/from
the device and the cpu.

This simply throws out the 53c700 driver's optimistic setting of the
best possible transport parameters and replaces it with DV
determination.  It also adds a missing report_bus_reset() callback and
finally does a delayed DV on device errors.

From: Andi Kleen <ak@suse.de>

This patch has been in the SuSE 2.4 kernel forever, but for some reason
never made it mainline.

It works around the infamous "only works stable when a mouse is plugged in"
problem some AMD 768MPX Dual Athlon chipsets have.  The problem happens
because the chipset can hang when PCI prefetch strides from a RAM page into
the VGA text buffer.  When a PS2 mouse is plugged in the BIOS reserves a
page before the VGA text buffer, which stops the prefetch early.

This patch always reserves this page when the chipset could be AMD768MPX.
This can be only done early in bootmem setup.  Because it's difficult to
scan the PCI bus that early it just always reserves this page when the CPU
is an Athlon.  Normally it should not make a difference because the BIOS
will have reserved that page anyways when a PS/2 mouse is plugged in.

kernel parameters:

   raid=partitionable

   md=d....
     will assemble an array as a partitionable array.

Use "shedule_timeout()" instead of yield() as it seems to wait for less
time.

From: Rusty Russell <rusty@rustcorp.com.au>

Make it clear that the reason we do wait_task_inactive is because
kthread_bind frobs with k->thread_info->cpu, which is only legal because
the task is definitely not running.

We can't use the normal migration thread code here, because it doesn't let
us bind to cpus which are offline yet, and also because we use this to
start the migration threads themselves.

From: Arnd Bergmann <arnd@arndb.de>

Dave Jones already removed some of the useless __KERNEL_SYSCALLS__ defines
in various files, this gets rid of almost all the others.  Replacing
execve() is nontrivial, so I left those in for now.

For all the other system calls that are currently used from inside the
kernel, calling the sys_* function directly should always have an identical
effect.

Distribute boot time memory allocations across all nodes, from Manfred
Spraul.

We want to spread memory across nodes to avoid all allocations ending
up on node 0.

Spreading boot time allocations around also helps us to avoid node 0
becoming the hot node.

I took it for a spin:
