Subject: [PATCH v4 0/3] livepatch: Cleanup of reliable stacktrace warnings

This is the fourth attempt to improve the situation of reliable stack
trace warnings in livepatch. Based on discussion in
20190531074147.27616-1-pmladek@...e.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]

Miroslav Benes (2):
  stacktrace: Remove weak version of save_stack_trace_tsk_reliable()
  Revert "livepatch: Remove reliable stacktrace check in
    klp_try_switch_task()"

Petr Mladek (1):
  livepatch: Remove duplicate warning about missing reliable stacktrace
    support
