In addition to bringing in upstream commits, this merge also makes minor
changes to mainitain compatibility with upstream:

The definition of list_next_entry in qcrypto.c and ipa_dp.c has been
removed, as upstream has moved the definition to list.h. The implementation
of list_next_entry was identical between the two.

irq.c, for both arm and arm64 architecture, has had its calls to
__irq_set_affinity_locked updated to reflect changes to the API upstream.

Finally, as we have removed the sleep_length member variable of the
tick_sched struct, all changes made by upstream commit ec804bd9 do not
apply to our tree and have been removed from this merge. Only
kernel/time/tick-sched.c is impacted.
