== 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 ==
aec45e857c55 ("s390/qeth: use vzalloc for QUERY OAT buffer")
== Regression Potential ==
Low, limited to s390.
== Test Case ==
IBM verified testing of this commit up-front.
