arm64: compat: Provide definition for COMPAT_SIGMINSTKSZ

arch/arm/ defines a SIGMINSTKSZ of 2k, so we should use the same value
for compat tasks.

qeth: check not more than 16 SBALEs on the completion queue

BugLink: http://bugs.launchpad.net/bugs/1750568

af_iucv socket programs with HiperSockets as transport make use of the qdio
completion queue. Running such an af_iucv socket program may result in a
crash:

qeth_qdio_cq_handler() analyzes SBALs on this completion queue, but does
not observe the limit of 16 SBAL elements per SBAL. This patch adds the
additional check to process not more than 16 SBAL elements.

xfrm: Ignore socket policies when rebuilding hash tables

BugLink: http://bugs.launchpad.net/bugs/1613787

Whenever thresholds are changed the hash tables are rebuilt. This is
done by enumerating all policies and hashing and inserting them into
the right table according to the thresholds and direction.

Because socket policies are also contained in net->xfrm.policy_all but
no hash tables are defined for their direction (dir + XFRM_POLICY_MAX)
this causes a NULL or invalid pointer dereference after returning from
policy_hash_bysel() if the rebuild is done while any socket policies
are installed.

Since the rebuild after changing thresholds is scheduled this crash
could even occur if the userland sets thresholds seemingly before
installing any socket policies.
