so we can merge io_apic_32.c and io_apic_64.c
v2: Use cpu_online_map as target cpus for bigsmp, just like 64-bit is doing.
Also remove some unused TARGET_CPUS macro.
v3: need to check if desc is null in smp_irq_move_cleanup
also migration needs to reset vector too, so copy __target_IO_APIC_irq
from 64bit.
(the duplication will go away once the two files are unified.)

WARNING: vmlinux.o(.cpuinit.text+0x3cc4): Section mismatch in reference from the function uv_cpu_init() to the function .init.text:uv_system_init()
The function __cpuinit uv_cpu_init() references
a function __init uv_system_init().
If uv_system_init is only used by uv_cpu_init then
annotate uv_system_init with a matching annotation.
uv_system_init was ment to be called only once, so do it from codepath
(native_smp_prepare_cpus) which is called once, right before activation
of other cpus (smp_init).
Note: old code relied on uv_node_to_blade being initialized to 0,
but it'a not initialized from anywhere.

This patch is the result of an automatic script that consolidates the
format of all the headers in include/asm-x86/.
The format:
1. No leading underscore. Names with leading underscores are reserved.
2. Pathname components are separated by two underscores. So we can
distinguish between mm_types.h and mm/types.h.
3. Everything except letters and numbers are turned into single
underscores.

This patch changes smpboot.c so that it can start slave cpus running
in UV non-unique apicid mode. The SIPI must be sent using a UV-specific
mechanism.

Add functions that can be used to determine if an x86_64
system is a SGI "UV" system. UV systems come in 3 types and
are identified by the OEM ID in the MADT.
