i applied your patch series on linux-next-20190103. On my Raspberry Pi 3B+ (defconfig) i'm getting this from sysfs: l1tf:Not affected meltdown:Not affected spec_store_bypass:Unknown spectre_v1:Mitigation: __user pointer sanitization spectre_v2:Unknown AFAIK it has 4 Cortex-A53 cores (no PSCI firmware), so shouldn't be affected. How can this be fixed? Thanks Stefan
