Srinivas Ramana 21393ff3ea arm64: Add BTAC/LinkStack sanitizations for Kryo cores ... Kryo cores are exposed to two vulnerabilities due to subroutine return (called LINK-STACK) and branch target predictors. These two issues can be mitigated through software workarounds. Kernel: - Apply LINK-STACK mitigation which is to issue 16 nested BL instructions on process context switch 'cpu_do_switch_mm()' where ASID changes. - Apply psci based branch predictor invalidation. use the kryo core detection routine (based on MIDR) from the commit bb48711800e6d ("arm64: cpu_errata: Add Kryo to Falkor 1003 errata") by Stephen Boyd <sboyd@codeaurora.org>.
