The Linux kernel configuration item CONFIG_ARM64_ERRATUM_1530923
has multiple definitions:
arch/arm64/Kconfig
The configuration item CONFIG_ARM64_ERRATUM_1530923:
(none)
This option adds a workaround for ARM Cortex-A55 erratum 1530923.
Affected Cortex-A55 cores (r0p0, r0p1, r1p0, r2p0) could end-up with corrupted TLBs by speculating an AT instruction during a guest context switch.
If unsure, say Y.
