I did it on purpose (and gave the warning a miss...) and I consider
iosapic_free_rte() is no longer needed.
I decided to remain iosapic_rte_info to keep gsi-to-irq binding
after device disable. Indeed it needs some extra memory, but it
is only "sizeof(iosapic_rte_info) * <the number of removed devices>"
bytes and has no memory leak becasue re-enabled devices use the
iosapic_rte_info which they used before disabling.

Add mapping tables between irqs and vectors, and its management code.
This is necessary for supporting multiple vector domain because 1:1
mapping between irq and vector will be changed to n:1.
The irq == vector relationship between irqs and vectors is explicitly
remained for percpu interrupts, platform interrupts, isa IRQs and
vectors assigned using assign_irq_vector() because some programs might
depend on it.
And I should consider the following problem.
When pci drivers enabled/disabled devices dynamically, its irq number
is changed to the different one. Therefore, suspend/resume code may
happen problem.
To fix this problem, I bound gsi to irq.

Many of IOSAPIC codes depends on the flollowing assumptions, but these
would become invalid when multiple vector domain will be supported in
the future.
- 1:1 mapping between IRQ and vector
- IRQ == vector
To fix those invalid assumptions, this patch changes iosapic_intr_info[]
to be indexed by irq number instead of vector.

Make it possible to use __start_notes and __stop_notes without getting a GPREL
overflow error from the FRV linker.
Small variables that would otherwise be in .data or .bss may, depending on the
arch, be placed in special sections (.sdata or .sbss) that permit single
instruction references on fixed instruction width machines.
__start_notes and __stop_notes aren't really char variables, and certainly
don't refer to data in .data or .bss. Making them type "void" fools the
compiler into not assuming anything about them.

The memory slot management functions were oriented against vcpu 0, where
they should be kvm-wide. This causes hangs starting X on guest smp.
Fix by making the functions (and resultant tail in the mmu) non-vcpu-specific.
Unfortunately this reduces the efficiency of the mmu object cache a bit. We
may have to revisit this later.

We need to distinguish between large page shadows which have the nx bit set
and those which don't. The problem shows up when booting a newer smp Linux
kernel, where the trampoline page (which is in real mode, which uses the
same shadow pages as large pages) is using the same mapping as a kernel data
page, which is mapped using nx, causing kvm to spin on that page.

This moves all the common parts for the Sparc, Sparc64 and PowerPC
of_device.c files into drivers/of/device.c.
Apart from the simple move, Sparc gains of_match_node() and a call to
of_node_put in of_release_dev(). PowerPC gains better recovery if
device_create_file() fails in of_device_register().
