bug: Let report_bug_entry() provide the correct bugaddr
report_bug_entry() always provides zero for bugaddr but could easily
extract the correct address from the provided bug_entry. Just do that to
have proper warning messages.
E.g. adding an artificial:
void foo(void) { WARN_ONCE(1, "bar"); }
function generates this warning message:
WARNING: arch/s390/kernel/setup.c:1017 at 0x0, CPU#0: swapper/0/0
^^^
With the correct bug address this changes to:
WARNING: arch/s390/kernel/setup.c:1017 at foo+0x1c/0x40, CPU#0: swapper/0/0
^^^^^^^^^^^^^
