#     kmemleak: Do not corrupt the object_list during clean-up
#     
#     In case of an error (e.g. memory pool too small), kmemleak disables
#     itself and cleans up the already allocated metadata objects. However, if
#     this happens early before the RCU callback mechanism is available,
#     put_object() skips call_rcu() and frees the object directly. This is not
#     safe with the RCU list traversal in __kmemleak_do_cleanup().
#     
#     Change the list traversal in __kmemleak_do_cleanup() to
#     list_for_each_entry_safe() and remove the rcu_read_{lock,unlock} since
#     the kmemleak is already disabled at this point. In addition, avoid an
#     unnecessary metadata object rb-tree look-up since it already has the
#     struct kmemleak_object pointer.
#

WARNING: vmlinux.o(.text+0x31e4): Section mismatch in reference from the variable __boot_from_prom to the function .init.text:prom_init()
The function __boot_from_prom() references
the function __init prom_init().
This is often because __boot_from_prom lacks a __init 
annotation or the annotation of prom_init is wrong.

WARNING: vmlinux.o(.text+0x33c8): Section mismatch in reference from the variable start_here_common to the function .init.text:start_kernel()
The function start_here_common() references
the function __init start_kernel().
This is often because start_here_common lacks a __init 
annotation or the annotation of start_kernel is wrong.
