Linux Kernel Configuration
└─>Processor type and features
└─>Class II Instructions
└─>Have instruction l.ror for rotate right
In linux kernel since version 5.2 (release Date: 2019-07-07)
This config enables gcc to generate l.ror instructions when compiling
the kernel which in general will improve performance and reduce the
binary size.
Select this if your implementation has support for the Class II
l.ror rotate right instruction.
Say N if you are unsure.
