If there is a mixture of specifying sections for code in gcc and assembler then if the assembler code do not add the "ax" flags the linker will see this as two different sections and generate unique sections for each. ld does so by adding a dot and a number. Teach modpost to warn if a section shows up that match this pattern - but do this only for non-debug sections. It will result in warnings like this: WARNING: vmlinux.o (.sched.text.1): unexpected section name. The (.[number]+) following section name are ld generated and not expected. Did you forget to use "ax"/"aw" in a .S file? Note that for example <linux/init.h> contains section definitions for use in .S files. All warnings seen with a defconfig build for: x86 (32+64bit) and sparc64 has been fixed (via respective maintainers). arm, powerpc (64 bit), s390 (32 bit), ia64, alpha, sh4 checked - no warnings seen with a defconfig build.
