   modified by appending any of the following modifiers to the field
         .hex        display a number as a hex value
 	.sym        display an address as a symbol
 	.sym-offset display an address as a symbol and offset
 	.syscall    display a syscall id as a system call name
 	.execname   display a common_pid as a program name
+	.log2       display log2 value rather than raw number
   Note that in general the semantics of a given field aren't
   interpreted when applying a modifier to it, but there are some
   restrictions to be aware of in this regard:
     - only the 'hex' modifier can be used for values (because values
       are essentially sums, and the other modifiers don't make sense
       in that context).
