** Description changed:
+
+ == SRU Justification ==
+ IBM reports the qethqoat tool fails. qeth_query_oat_command() currently
+ allocates the kernel buffer for the SIOC_QETH_QUERY_OAT ioctl with kzalloc.
+
+ This commit will cause the use of vzalloc() instead of kzalloc(), backing
+ the allocation with non-contiguous memory.
+
+ Xenial also needs this commit, but requres a slightly different
+ backport. It's SRU will be sent separate.

+ == Fix ==
