We don't need to allocated LPIDs from real mode, so it should be OK.

Does this fix the linux-next build problems that I have reported?

irq_domain_add_simple() was a stop-gap measure until complete irq_domain
support was complete. This patch removes the irq_domain_add_simple()
interface.

This patch removes the simplistic implementation of irq_domains and enables
the powerpc infrastructure for all irq_domain users. The powerpc
infrastructure includes support for complex mappings between Linux and
hardware irq numbers, and can manage allocation of irq_descs.
This patch also convert
Each revmap type has different arguments for setting up the revmap.
This patch splits up the generator functions so that each revmap type
can do its own setup and the user doesn't need to keep track of how
each revmap type handles the arguments.

Add support for a legacy mapping where irq = (hwirq - first_hwirq + first_irq)
so that a controller driver can allocate a fixed range of irq_descs and use
a simple calculation to translate back and forth between linux and hw irq
numbers. This is needed to use an irq_domain with many of the ARM int
No functional changes. Replaces non-exported references to 'host' with domain.

This patch only moves the code. It doesn't make any changes, and the
code is still only compiled for powerpc. Follow-on patches will generalize
the code for other architectures.

This patch drops the powerpc-specific irq_map table and replaces it with
directly using the irq_alloc_desc()/irq_free_desc() interfaces for allocating
and freeing irq_desc structures.
This patch is a preparation step for generalizing the powerpc-specific virq
infrastructure to become irq_domains.
There is only one user, and it is trivial to open-code.

Part of the series to unify the irq remapping mechanisms in the
kernel. A follow up patch will copy the powerpc implementation into
kernel/irq/irqdomain.c, which will be a lot easier if the structures
are identical.
Where they differ, I've chose to use the powerpc names since there is
a lot more

Here are the patches that I've been working on to finish up the creation
of the generic irq_domain infrastructure.
I'm taking a different approach that I originally intended.
Originally I intended to start with the basic design of irq_host from
powerpc, but there were some things about the impleme

EEH may happen during a PCI driver probe. If the driver is trying to
access some register in a loop, the EEH code will try to print the
driver name. But the driver pointer in struct pci_dev is not set until
probe returns successfully.
Use a function to test if the device and the driver pointer is
This fixes a hang that was observed during live partition migration.
Since stop_topology_update must not be called from an interrupt
context, call it earlier in the migration process. The hang observed
