Why This File Exists

CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.

 * - starting_index_kind is one of the following, depending on the event:
 *
 *   hw_chip_id: hardware chip id or -1 for current hw chip
 *   partition_id
 *   sibling_part_id,
 *   phys_processor_idx:
 *   0xffffffffffffffff: or -1, which means it is irrelavant for the event
 *
 * __count(offset, bytes, name):
 *	a counter that should be exposed via perf
 * __field(offset, bytes, name)
 *	a normal field
 * __array(offset, bytes, name)
 *	an array of bytes
 *
 *
 *	@bytes for __count, and __field _must_ be a numeral token
 *	in decimal, not an expression and not in hex.
 *
 *
 * TODO:
 *	- expose secondary index (if any counter ever uses it, only 0xA0
 *	  appears to use it right now, and it doesn't have any counters)
 *	- embed versioning info
