If you fix the issue, kindly add following tag as appropriate
Reported-by: kernel test robot <[email protected]>
All warnings (new ones prefixed by >>, old ones prefixed by <<):
WARNING: modpost: vmlinux.o(.text+0x1a8edb8): Section mismatch in
reference from the function stop_machine() to the function
.init.text:intel_rng_hw_init()
The function stop_machine() references
the function __init intel_rng_hw_init().
This is often because stop_machine lacks a __init
annotation or the annotation of intel_rng_hw_init is wrong.
I'd be very interested to know how the identified patch would be able to
have this effect.
Hi Clang Team,
The problem is found by the latest clang, and I can't reproduce it with
clang-11,
could you take a look?
Best Regards,
Rong Chen
