Jan Engelhardt 36cbd3dcc1 net: mark read-only arrays as const
String literals are constant, and usually, we can also tag the array
of pointers const too, moving it to the .rodata section.

Tejun Heo b9bf3121af percpu: use DEFINE_PER_CPU_SHARED_ALIGNED()
There are a few places where ___cacheline_aligned* is used with
DEFINE_PER_CPU().  Use DEFINE_PER_CPU_SHARED_ALIGNED() instead.

DEFINE_PER_CPU_SHARED_ALIGNED() applies alignment only on SMPs.  While
all other converted places used _in_smp variant or only get compiled
for SMP, net/rds used unconditional ____cacheline_aligned.  I don't
see any reason these data structures should be aligned on UP and thus
converted together.

Andy Grover fcd8b7c0ec RDS: Add iWARP support
Support for iWARP NICs is implemented as a separate
RDS transport from IB. The code, however, is very
similar to IB (it was forked, basically.) so let's keep
it in one changeset.

The reason for this duplicationis that despite its similarity
to IB, there are a number of places where it has different
semantics. iwarp zcopy support is still under development,
and giving it its own sandbox ensures that IB code isn't
disrupted while iwarp changes. Over time these transports
will re-converge.
