68 On a homogeneous system, the CPU affinity of a task is preserved across
71 affinity mask contains 64-bit-only CPUs. In this situation, the kernel
72 determines the new affinity mask as follows:
74 1. If the 32-bit-capable subset of the affinity mask is not empty,
75 then the affinity is restricted to that subset and the old affinity
84 affinity of the task is then changed to match the 32-bit-capable
87 3. On failure (i.e. out of memory), the affinity is changed to the set
91 invalidate the affinity mask saved in (1) and attempt to restore the CPU
92 affinity of the task using the saved mask if it was previously valid.
