└─>Cortex-X4: 3194386: workaround for MSR SSBS not self-synchronizing
This option adds the workaround for ARM Cortex-X4 erratum 3194386.

On affected cores "MSR SSBS, #0" instructions may not affect
subsequent speculative instructions, which may permit unexepected
speculative store bypassing.

Work around this problem by placing a speculation barrier after
kernel changes to SSBS. The presence of the SSBS special-purpose
register is hidden from hwcaps and EL0 reads of ID_AA64PFR1_EL1, such
that userspace will use the PR_SPEC_STORE_BYPASS prctl to change
SSBS.

If unsure, say Y.
