In linux kernel since version 3 (release Date: 2011-07-21)
This option enables kernel support for the PowerPC Initiate
Coprocessor Store Word (icswx) coprocessor instruction on POWER7
or newer processors.
This option is only useful if you have a processor that supports
the icswx coprocessor instruction. It does not have any effect
on processors without the icswx coprocessor instruction.
This option slightly increases kernel memory usage.
If in doubt, say N here.
