The ppc64le implementation of save_stack_trace_tsk_reliable() is
exported, so do the same with x86.

And what's the in tree module user of this? I can't find one and just
because PPC has an export with no user is not a convincing argument to add
another one. The proper solution is to remove the unused PPC export.


Good point.

For that matter, I do see in-tree modules making use of save_stack_trace, but who is calling save_stack_trace_tsk (exported by most arches) and save_stack_trace_regs (exported by openrisc, powerpc, s390)?
