697eaad417 [IA64] Minor cleanups - remove CONFIG_ACPI_DEALLOCATE_IRQ
The config option 'CONFIG_ACPI_DEALLOCATE_IRQ' is no longer
needed. This patch removes it.

error condition is passed along by acpi_register_gsi().

3b5cc09033 [IA64] assign_irq_vector() should not panic
Current assign_irq_vector() will panic if interrupt vectors is running
out. But I think how to handle the case of lack of interrupt vectors
should be handled by the caller of this function. For example, some
PCI devices can raise the interrupt signal via both MSI and I/O
APIC. So even if the driver for these device fails to allocate a
vector for MSI, the driver still has a chance to use I/O APIC based
interrupt. But currently there is no chance for these driver to use
I/O APIC based interrupt because kernel will panic when
assign_irq_vector() fails to allocate interrupt vector.

The following patch changes assign_irq_vector() for ia64 to return
-ENOSPC on error instead of panic (as i386 and x86_64 versions do).

0e888adc41 [PATCH] ACPI based I/O APIC hot-plug: ia64 support
This is an ia64 implementation of acpi_register_ioapic() and
acpi_unregister_ioapic() interfaces.

24eeb568ae [IA64] vector sharing (Large I/O system support)
Current ia64 linux cannot handle greater than 184 interrupt sources
because of the lack of vectors. The following patch enables ia64 linux
to handle greater than 184 interrupt sources by allowing the same
vector number to be shared by multiple IOSAPIC's RTEs. The design of
this patch is besed on "Intel(R) Itanium(R) Processor Family Interrupt
Architecture Guide".

Even if you don't have a large I/O system, you can see the behavior of
vector sharing by changing IOSAPIC_LAST_DEVICE_VECTOR to fewer value.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
