Same result with gcc version 4.4.3 (Debian 4.4.3-5)

I put here the code :

        if (nr)
                atomic_sub(nr, &vmap_lazy_nr);

                if (force_flush)
                        flush_tlb_kernel_range(*start, *end);

                spin_lock(&vmap_area_lock);
                list_for_each_entry_safe(va, n_va, &valist, purge_list)
                        __free_vmap_area(va);
                spin_unlock(&vmap_area_lock);
        }
        spin_unlock(&purge_lock);

The ligne 582 in error is the "spin_unlock(&purge_lock);"
