In linux kernel since version 2.6.31 (release Date: 2009-09-09)
Setting this value allows to align ring buffer descriptors into their
own cache lines. Value of 4 corresponds to the typical 32 byte line
(the descriptor is 16 bytes). This is necessary on systems that lack
cache coherence, an example is PowerMac 5500. Otherwise 0 is safe.
Default is 0, and range is 0 to 31.
