Using gcc 9.2 to build current 5.X kernel.org source trees, I'm seeing several warnings like the following during the linking of "vmlinux.o": WARNING: vmlinux.o(__ex_table+0x11d0): Section mismatch in reference from the (unknown reference) (unknown) to the (unknown reference) .alphalib:(unknown) The relocation at __ex_table+0x11d0 references section ".alphalib" which is not in the list of authorized sections. If you're adding a new section and/or if this reference is valid, add ".alphalib" to the list of authorized sections to jump to on fault. This can be achieved by adding ".alphalib" to OTHER_TEXT_SECTIONS in scripts/mod/modpost.c. This is directly due to the workarounds we put in place on alpha for dealing with relocation errors during the linking of large executables (such as "firefox" :-)). These are warnings, but sending a fix upstream sooner rather than later would probably be a good idea. --Bob
