When iommu_init_early_pSeries() was added, ages ago, we forgot to remove
the code that checks /chosen/linux,iommu-off in pSeries_init_early(). We
do it now in iommu_init_early_pSeries().

htab_bolt_mapping() takes a vstart and pstart parameter, but all but one of
its callers actually pass it vstart and vstart. Luckily before it passes
paddr (calculated from paddr) to the hpte_insert routines it calls
virt_to_abs() (aka. __pa()) on the address, so there isn't actually a bug.
map_io_page() however does pass pstart properly, so currently it's broken
AFAICT because we're calling __pa(paddr) which will get us something very
large. Presumably no one's calling map_io_page() in the right context.
Anyway, change htab_bolt_mapping() callers to properly pass pstart, and then
use it properly in htab_bolt_mapping(), ie. don't call __pa() on it again.
Booted on p5 LPAR, iSeries and Power3.

We can plug the boot cpu into its node independently of whether numa
topology is detected. And numa_setup_cpu does the right thing for all
cases now, so remove special-casing for non-numa from the cpu hotplug
callback.

The powerpc numa code unconditionally onlines all nodes from 0 to the
highest node id found, regardless of whether cpus or memory are
present in the nodes. This wastes 8K per node and complicates some
cpu and memory hotplug situations, such as adding a resource that
doesn't map to one of the nodes discovered at boot.
Set nodes online as resources are scanned. Fall back to node 0 only
when we're sure this isn't a NUMA machine.
Instead of defaulting to node 0 for cases of hot-adding a resource
which doesn't belong to any initialized node, assign it to the first
online node.

Code to handle Power4's invalid node id (0xffff) is duplicated for cpu
and memory. Better to handle this case in one place --
of_node_to_nid. Overall behavior should be unchanged.

Since we effectively treat the domain ids given to us by firmare as

map_cpu_to_node does not need to be inline, it is never called in a
hot path.
map_cpu_to_node, numa_setup_cpu, and find_cpu_node can be marked
__cpuinit, as they are never used after boot if CONFIG_HOTPLUG_CPU=n.

At boot, the numa code is assigning boot_cpuid to node 0
unconditionally. Basically, numa_setup_cpu is being stupid about it,
but this is the minimal fix -- just call numa_setup_cpu(boot_cpuid)
later, after all nodes have been set online.

Alan noted: "bmdma may be zero but the bmdma_irq_clear function gets
called even in this case during pure PIO operation. Check we have a
bmdma before we use it."
I fixed this by adding a check for zero. While was I there, I fixed the
non-standard indentation of the small function's code.

The first performs the simplex clearing relevant to some chipsets that
report simplex by default but can in fact do more if poked. The second

This patch addresses a number of weird behaviours observed
for the sata_mv driver, by fixing an "off by one" bug in processing
of the EDMA response queue.
Basically, sata_mv was looking in the wrong place for
command results, and this produced a lot of unpredictable behaviour.

Original patch (and description) by Douglas Gilbert, with minor fixes
and API updates from me.
Changelog:
- make existing libata VPD device identification page (0x83)
supply the ATA serial number in the libata "vendor
specific" designator (from Chris Paulson-Ellis)
- add a "t10 vendor id based" designator as defined in
SAT rev 08 (section 10.3.4.2.3) that supplies ATA
model and serial numbers
- make the libata VPD page 0x83 more extensible (for
adding more designators in the future).
- rename EVPD to VPD in various places. Enable Vital
Product Data (EVPD) is a bit in the INQUIRY cdb.
