Just a variable width shift of long long with both arguments fetched
from deep indirection via pointers, and that all in a function with
register pressure (extracted from the XFS source, which does all kinds
of nasty things with long long)
I am actually not sure if the normal kernel contains even a variable
width long long shift.

suspects his own hacks. no fs corruption, but I do not run dbench normally)
