If the patch is short, please forward if you would be so kind.

I *think* what I want to do is the equivalent of the ".S" file '.text --> .section .alphalib,"ax"' substitution for the affected ".c" files in "arch/alpha/lib". At the risk of baring my ignorance to the world, is there a straightforward way of accomplishing that? The "objdump" tool confirms it's not a strict renaming of one section to another: the ".text" section still exists in the compiled ".S" files that were patched. --Bob -- To unsubscribe from this list: send the line "unsubscribe linux-alpha" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
