Hello!
This is the spectre-bhb backport for v4.14. This comes with an A76 timer workaround. v4.14 doesn't have a compat vdso, so doesn't need all the patches for that workaround. In particular, it doesn't need Marc's series: https://lore.kernel.org/linux-arm-kernel/20200715125614.3240269-1-maz@kernel...
I included the Kconfig change that restricts this to COMPAT, but not commit 0f80cad3124f ("arm64: Restrict ARM64_ERRATUM_1188873 mitigation to AArch32"), which is an invasive performance optimisation that wasn't marked as being for stable.
Thanks for these, all now queued up!
