Workaround for Neoverse N1 erratum 1257314 Neoverse N1 erratum 1257314 is a Cat B erratum [1], present in older revisions of the Neoverse N1 processor core. The workaround is to set a bit in the implementation defined CPUACTLR3_EL1 system register, which prevents parallel execution of divide and square root instructions.
