I ran into a build error:

/git/arm-soc/net/sctp/sm_sideeffect.c: In function 'sctp_do_sm':
/git/arm-soc/net/sctp/sm_sideeffect.c:1155:5: internal compiler error: Segmentation fault
int sctp_do_sm(struct net *net, enum sctp_event event_type,
^
0xa42b7f crash_signal

The bug is fixed in mainline gcc now, but I carry this as I have
not yet upgrade.
