Maybe you managed to take a fault against the symbol area between the _install_special_mapping() and the remap_pfn_range() call, but mmap_sem should prevent that. Or the remap_pfn_range() call never happened. Should map_vdso() be running _install_special_mapping() at all if image->sym_vvar_page==NULL? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
