4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christian Perle <christian.perle@xxxxxxxxxxx>
[ Upstream commit 3500cd73dff48f28f4ba80c171c4c80034d40f76 ]
Reading /proc/net/snmp6 yields bogus values on 32 bit kernels.
Use "u64" instead of "unsigned long" in sizeof().
Fixes: 4a4857b1c81e ("proc: Reduce cache miss in snmp6_seq_show")
