[ Upstream commit ccdd09e0fc0d5ce6dfc8360f0c88da9a5045b6ea ]
Trying to compile an x86 kernel on big endian results in this error:
net/ipv4/netfilter/iptable_nat.o: warning: objtool: iptable_nat_table_init+0x150: Unknown annotation type: 50331648 make[5]: *** [scripts/Makefile.build:287: net/ipv4/netfilter/iptable_nat.o] Error 255
Reason is a missing endian conversion in read_annotate(). Add the missing conversion to fix this.
