All warnings (new ones prefixed by >>, old ones prefixed by <<):

>> WARNING: modpost: vmlinux.o(.text+0x1db1e64): Section mismatch in reference from the function dccp_sysctl_exit() to the variable .init.text:.L0
The function dccp_sysctl_exit() references
the variable __init .L0 .
This is often because dccp_sysctl_exit lacks a __init
annotation or the annotation of .L0 is wrong.

The below error/warnings are from parent commit:
