I'm doing that now; and un-duplicating about a dozen instances of the
binary->string conversion loops used when reading out masks, and almost
as many string->binary parse_hex_value() routines used when reading in
masks.  There will be a single routine for each, in a new lib file.

Can you tell me, Bill, how it is that having:

  #define HEX_DIGITS (2*sizeof(cpumask_t))

leaves room for the terminating nul-byte?  Seems to me that
a lot of hexnum[] arrays might be one byte short.

One incompatibility with existing code:

    If I proceed along my current path, cpumasks, such as for
    irq or smp_affinity, will no longer be displayed in /proc
    with leading zero padding.

    I expect that this could be a problem ...

Complaints invited.
