Cortex-A76: 1165522: Speculative AT instruction using out-of-context translation regime could cause subsequent request to generate an incorrect translation
This option adds a workaround for ARM Cortex-A76 erratum 1165522.
Affected Cortex-A76 cores (r0p0, r1p0, r2p0) could end-up with
corrupted TLBs by speculating an AT instruction during a guest
context switch.

If unsure, say Y.
