Impact: fix lguest, clean up
32-bit lguest used used_vectors to record vectors, but that model of
allocating vectors changed and got broken, after we changed vector
allocation to a per_cpu array.
Try enable that for 64bit, and the array is used for all vectors that
are not managed by vector_irq per_cpu array.
Also kill system_vectors[], that is now a duplication of the
used_vectors bitmap.
[ merged in cpus4096 due to io_apic.c cpumask changes. ]
[ -v2, fix build failure ]

Impact: cleanup, remove on-stack cpumask.
The "map" arg is always cpu_online_mask. Importantly, set_affinity
always ands the argument with cpu_online_mask anyway, so we don't need
to do it in fixup_irqs(), avoiding a temporary.

Impact: cleanup
CONFIG_IRQBALANCE was removed in commit 8b8e8c1bf; this ifdef was still
around.

Change header guards named "ASM_X86__*" to "_ASM_X86_*" since:
a. the double underscore is ugly and pointless.
b. no leading underscore violates namespace constraints.

also add first_free_entry and pin_map_size, which were NR_IRQS derived
constants.

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.
