Alan Cox d027ed2e7a To analyze the allocation of swap blocks by blist functions, add a method
for analyzing the radix tree structures and reporting on the number, and
sizes, of maximal intervals of free blocks.  The report includes the number
of maximal intervals, and also the number of them in each of several size
ranges, from small (size 1, or 3 to 4) to large (28657 to 46367) with size
boundaries defined by Fibonacci numbers.  The report is written in the test
tool with the 's' command, or in a running kernel by sysctl.

The analysis of the radix tree frequently computes the position of the lone
bit set in a u_daddr_t, a computation that also appears in leaf allocation.
That computation has been moved into a function of its own, and optimized
for cases where an inlined machine instruction can replace the usual binary
search.
