The hardware counter ->event_base state records and encoding of
the "struct perf_event_map" entry used for the event.

We use this to make sure that when we have more than 1 event,
both can be scheduled into the hardware at the same time.

As usual, structure of code is largely cribbed from powerpc.

Since we now use the embedding percpu allocator we have to make the
vmalloc area at least as large as the stretch can be between nodes.

Besides some minor asm adjustments, this turned out to be pretty
trivial.

This makes sure every acpi_device has at least one ID.  If we build an
acpi_device for a namespace node with no _HID or _CID, we sometimes
synthesize an ID like "LNXCPU" or "LNXVIDEO".  If we don't even have
that, give it a default "device" ID.

Note that this means things like:
    /sys/devices/LNXSYSTM:00/LNXSYBUS:00/HWP0001:00/HWP0002:04/device:00
(a PCI slot SxFy device) will have "hid" and "modprobe" entries, where
they didn't before.  These aren't very useful (a HID of "device" doesn't
tell you what *kind* of device it is, so it doesn't help find a driver),
but I don't think they're harmful.
