This is the fourth attempt to improve the situation of reliable stack
trace warnings in livepatch. Based on discussion in
20190531074147.27616-1-pmla...@suse.com (v3).
Changes against v3:
+ weak save_stack_trace_tsk_reliable() removed, because it is not needed
anymore thanks to Thomas' recent improvements
+ klp_have_reliable_stack() check reintroduced in klp_try_switch_task()
Changes against v2:
+ Put back the patch removing WARN_ONCE in the weak
save_stack_trace_tsk_reliable(). It is related.
+ Simplified patch removing the duplicate warning from klp_check_stack()
+ Update commit message for 3rd patch [Josh]
