Without this, some versions of GNU ar fail to create
an archive index if the object files it is packing
together are of a different object format than ar's
default format (for example, binutils compiled to
default to 64-bit, with 32-bit objects).

Our device-tree unflattening code makes sure the name and type fields
of a device-node are not NULL. However, the code for dynamically
adding devices nodes which is used for pSeries hotplug for example
didn't do it, potentially causing crashes in some code that assume it
can always do things like strcmp on those.

This patch corrects a number of minor errors in the Ebony device tree:
- Missing (given as 0) cache sizes are added to the CPU node
- device_type properties are removed from nodes which don't
have a reasonably well defined device_type binding. This does require
a very small code change to locate the busses to be probed for
of_platform devices by 'compatible' instead of 'device_type'.
- A node is added for the SRAM controller
- The unit address of the small-flash node is adjusted to
correctly reflect the reg property.
- device_type values for the MAL and ZMII are updated to
reflected more up-to-date versions of the binding.
- An incorrect offset in the partition map for the large-flash
node is corrected.
- Some redundant values, already commented out are removed
entirely.

This changes the way of_platform_pci creates PCI host bridges such
that it uses request_phb_iospace() for mapping the IO ports, instead
of using the dynamic hotplug stuff. That guarantees the IO space
stays within the 2GB limit and thus doesn't break half of the legacy
drivers around.
Fixes a couple of warnings due to missing IO space while at it.
This patch is a temporary workaround for 2.6.22 before a more complete
rewrite of IO mappings is merged in 2.6.23

request_phb_iospace() can be called from different CPUs at init

ft_set_prop() from flatdevtree.c in the zImage wrapper will either
replace an existing property in the flat device tree, or add a new
property definiion if the given property isn't present.
However, when adding properties, it adds the property definition
immediately before the node's END_NODE tag, potentially after any
subnode definitions for the node. This confuses the kernel flat tree
parser in prom.c which assumes that all property definitions for a
node come before all subnode definitions.
This patch corrects ft_set_prop() so that it adds new properties
before the first subnode, instead of before the END_NODE tag.

When an rheap is created, the caller can specify the alignment to use. In
rh_alloc_align(), if a free block is found that is the exact size needed
(including extra space for alignment), that configured alignment value is not
used to align the pointer. Instead, the default alignment is used. If the
default alignment is smaller than the configured alignment, then the returned
value will not be aligned correctly.

Hypervisor interfaces need to be negotiated in order to use
some API calls reliably. So add a small set of interfaces
to request API versions and query current settings.
This allows us to fix some bugs in the hypervisor console:
1) If we can negotiate API group CORE of at least major 1
minor 1 we can use con_read and con_write which can improve
console performance quite a bit.
2) When we do a console write request, we should hold the
spinlock around the whole request, not a byte at a time.
What would happen is that it's easy for output from
different cpus to get mixed with each other.
3) Use consistent udelay() based polling, udelay(1) each
loop with a limit of 1000 polls to handle stuck hypervisor
console.

The current implementation of kdump on INIT events would enter
kdump processing on DIE_INIT_MONARCH_ENTER and DIE_INIT_SLAVE_ENTER
events. Thus, the monarch cpu would go ahead and boot up the kdump
On SN shub2 systems, this out-of-sync situation causes some slave
cpus on different nodes to enter POD.
This patch moves kdump entry points to DIE_INIT_MONARCH_LEAVE and
DIE_INIT_SLAVE_LEAVE. It also sets kdump_in_progress variable in
the DIE_INIT_MONARCH_PROCESS event to not dump all active stack
traces to the console in the case of kdump.
I have tested this patch on an SN machine and a HP RX2600.

This reverts commit f64da958dfc83335de1d2bef9d3868f30feb4e53.
Andi Kleen is unhappy with the changes, and they really do not seem
worth it. IPMI could use DIE_NMI_IPI instead of the new callback, even
though that ends up having its own set of problems too, mainly because
the IPMI code cannot really know the NMI was from IPMI or not.
Manually fix up conflicts in arch/x86_64/kernel/traps.c and
drivers/char/ipmi/ipmi_watchdog.c.
