This patch adds support for setting up a fixed IOMMU mapping on certain
cell machines.  For 64-bit devices this avoids the performance overhead of
mapping and unmapping pages at runtime.  32-bit devices are unable to use
the fixed mapping.

The fixed mapping is established at boot, and maps all of physical memory
1:1 into device space at some offset.  On machines with < 30 GB of memory
we setup the fixed mapping immediately above the normal IOMMU window.

For example a machine with 4GB of memory would end up with the normal
IOMMU window from 0-2GB and the fixed mapping window from 2GB to 6GB. In
this case a 64-bit device wishing to DMA to 1GB would be told to DMA to
3GB, plus any offset required by firmware.  The firmware offset is encoded
in the "dma-ranges" property.

On machines with 30GB or more of memory, we are unable to place the fixed
mapping above the normal IOMMU window as we would run out of address space.
Instead we move the normal IOMMU window to coincide with the hash page
table, this region does not need to be part of the fixed mapping as no
device should ever be DMA'ing to it.  We then setup the fixed mapping
from 0 to 32GB.

Add support to cell_iommu_setup_page_tables() for handling two windows,

In order to support the fixed IOMMU mapping (in a subsequent patch),
we need the hash table to be inside the IOMMUs DMA window.  This is
usually 2G, but let's make sure the hash table is under 1G as that
will satisfy the IOMMU requirements and also means the hash table will
be on node 0.

Tony says:

| The CONFIG_SMP=n path in ia64 makes quite radical changes ... rather
| than putting all the per-cpu stuff into the top 64K of address space
| and providing a per-cpu TLB mapping for that range to a different
| physical address ... it just makes all the per-cpu stuff link as ordinary
| variables in .data.

the new generic percpu code got confused about this as PER_CPU_ATTRIBUTES
was defined even on UP, so it picked up that small memory model - which
was not possible to get linked. The right fix is to only define that
on SMP. This resolved the build failures in my cross-compiling environment.

also link these variables into the .percpu section even on UP - some
assembly code has offset dependencies. (such as GET_IA64_MCA_DATA() in

read_rom() obtained a fresh new fw_device.generation for each read
transaction.  Hence it was able to continue reading in the middle of the
ROM even if a bus reset happened.  However the device may have modified
the ROM during the reset.  We would end up with a corrupt fetched ROM
image then.

Although all of this is quite unlikely, it is not impossible.
Therefore we now restart reading the ROM if the bus generation changed.

Note, the memory barrier in read_rom() is still necessary according to
tests by Jarod Wilson, despite of the ->generation access being moved up
in the call chain.
