Just a heads up. I have a patch [1] which moves the "check_local_cpu_errata()"
around to smp_prepare_boot_cpu(). This patch should still work fine with that
case. Only that may be we could move the jump_lable_init() to
smp_prepare_boot_cpu(),
before we call "update_cpu_errata_work_arounds()" for Boot CPU.
IIUC, we wouldn't call update_cpu_errata_work_arounds() until the CPU
feature infrastructure is initialised via cpuinfo_store_boot_cpu(). So
I don't think moving the jump_label_init() call above is necessary.
Right, as I said, your patch should work fine even with that change. Its just
that,
jump_label_init() (a generic kernel setup) can be called from a better visible
place (smp_prepare_boot_cpu()) than from a less interesting place with the patch
below.
