Should there be a corresponding entry in the "Features" line of
/proc/cpuinfo for the new lam_bh capability?

Every other feature that sets elf_hwcap in cpu_probe_common() also
has a matching seq_puts() in show_cpuinfo() in proc.c:

arch/loongarch/kernel/proc.c:show_cpuinfo() {
    ...
    if (cpu_has_lam)
            seq_puts(m, " lam");
    if (cpu_has_scq)
            seq_puts(m, " scq");
    ...
}

The new cpu_has_lam_bh is missing from this list.
