[SRU][Xenial][PATCH 0/1] s390/qeth: use vzalloc for QUERY OAT buffer

[Joseph Salisbury]

BugLink: https://bugs.launchpad.net/bugs/1793086

== 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.

Bionic and Cosmic also need this commit, but they are clean cherry picks
so have been SRU'd separatly.

== 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.
