Alpha Linux kernel fails with inconsistent kallsyms data
The build of the Alpha Linux kernel currently fails[1] with inconsistent
kallsyms data. As I never saw that before, I thought about hardware
problems. But in fact it is a bug in the Linux kernel.
The end of the rodata section is marked with the "__end_rodata" symbol.
This symbol have different aligning constraints than the inittext parts
and therefor the start marked "_sinittext". Because of that the
__end_rodata symbol shifts between < _sinittext and == _sinittext. The
later variant is seen as a code symbol and recorded in the kallsyms data.
On fix would be to move the exception table a little bit and get some
space between that two areas.
