Johan Almbladh 72570224bb mips, bpf: Add JIT workarounds for CPU errata ... This patch adds workarounds for the following CPU errata to the MIPS eBPF JIT, if enabled in the kernel configuration. - R10000 ll/sc weak ordering - Loongson-3 ll/sc weak ordering - Loongson-2F jump hang The Loongson-2F nop errata is implemented in uasm, which the JIT uses, so no additional mitigations are needed for that.
