complete e390f9a port for v4.9.106
objtool ports introduced in v4.9.106 were not totally complete. Therefore
they resulted in issues like:
module: overflow in relocation type 10 val XXXXXXXXXXX
‘usbcore’ likely not compiled with -mcmodel=kernel
module: overflow in relocation type 10 val XXXXXXXXXXX
‘scsi_mod’ likely not compiled with -mcmodel=kernel
Missing part was the complete backport of commit e390f9a.
Original notes by Josh Poimboeuf:
The '__unreachable' and '__func_stack_frame_non_standard' sections are
only used at compile time. They're discarded for vmlinux but they
should also be discarded for modules.
Since this is a recurring pattern, prefix the section names with
".discard.". It's a nice convention and vmlinux.lds.h already discards
such sections.
Also remove the 'a' (allocatable) flag from the __unreachable section
since it doesn't make sense for a discarded section.
