Description Rod Nayfield 2006-08-21 14:29:49 UTC 
This will allow default_affinity= to be set to a bitmask (lowest bit = cpu 0,
and so on).

Examples:
default_affinity=0x1  (cpu 0 only)
default_affinity=0x3  (cpu 0 and 1 only)
default_affinity=0x00002 (cpu 1 only)

note that taskset ignores bits not corresponding to logical CPUs.  Thus
0x00000001 is valid even on a 2-way system.

As discussed previously.  Patch attached.
