Public bug reported:
Building the Ubuntu kernel at version 4.4.0-97.120 or 4.4.0-98.121 gives
warnings when linking apparmor.o such as:
LD security/apparmor/apparmor.o
WARNING: security/apparmor/apparmor.o(.text+0x1087b): Section mismatch in
reference from the function param_get_mode() to the variable
.init.data:apparmor_initialized
(next build fault)
The function param_get_mode() references
the variable __initdata apparmor_initialized.
This is often because param_get_mode lacks a __initdata
annotation or the annotation of apparmor_initialized is wrong.
I believe this is because the __initdata annotation was removed from
security/apparmor/lsm.c but not from security/apparmor/include/lib.h
The following patch cleans the compilation warnings, but may not be the
correct fix:
