When an IRQ safe device is attached to a no sleep domain, genpd prints a
warning once, as to indicate it is a suboptimal configuration from power
consumption point of view.
However the warning doesn't make sense for an always on domain, since it
anyway remains powered on. Therefore, let's change to not print the warning
for this configuration.

The current code in genpd_sync_power_off(), doesn't care about potential
errors being returned from genpd's ->power_off() callback.
Obviously this behaviour could lead to problems, such as incorrectly
setting the genpd's status to GPD_STATE_POWER_OFF, but also to incorrectly
decrease the subdomain count for the masters, which potentially allows them
to be powered off in the next recursive call to genpd_sync_power_off().
Let's fix this behaviour by bailing out when the ->power_off() callback
returns an error code.

The current way to implement an always on PM domain consists of returning
-EBUSY from the ->power_off() callback. This is a bit different compared to
using the always on genpd governor, which prevents the PM domain from being
powered off via runtime suspend, but not via system suspend.
The approach to return -EBUSY from the ->power_off() callback to support
always on PM domains in genpd is suboptimal. That is because it requires
genpd to follow the regular execution path of the power off sequence, which
ends by invoking the ->power_off() callback.
To enable genpd to early abort the power off sequence for always on PM
domains, it needs static information about these configurations. Therefore
let's add a new genpd configuration flag, GENPD_FLAG_ALWAYS_ON.
Users of the new GENPD_FLAG_ALWAYS_ON flag, are by genpd required to make
sure the PM domain is powered on before calling pm_genpd_init(). Moreover,
users don't need to implement the ->power_off() callback, as genpd doesn't
ever invoke it.

This workqueue is used by our storage target mode ULPs
via the new CQ API. Recent observations when working
with very high-end flash storage devices reveal that
UNBOUND workqueue threads can migrate between cpu cores
and even numa nodes (although some numa locality is accounted
for).
While this attribute can be useful in some workloads,
it does not fit in very nicely with the normal
run-to-completion model we usually use in our target-mode
ULPs and the block-mq irq<->cpu affinity facilities.
The whole block-mq concept is that the completion will
land on the same cpu where the submission was performed.
The fact that our submitter thread is migrating cpus
can break this locality.
We assume that as a target mode ULP, we will serve multiple
initiators/clients and we can spread the load enough without
having to use unbound kworkers.
Also, while we're at it, expose this workqueue via sysfs which
is harmless and can be useful for debug.

This creates a situation where all virtual mappings of the same physical
page share the same virtual cache index and guarantees VIPT coherence.
Otherwise the cache is non-coherent and the kernel will not see writes
by userspace when reading the shared page (or vice-versa).

Pull IOMMU fixes from Joerg Roedel:
"A few fixes piled up:
- fix a NULL-ptr dereference that happens in VT-d on some platforms
- a fix for ARM MSI region reporting, so that a sane interface makes
it to a released kernel
- fixes for leaf-checking in ARM io-page-table code
- two fixes for IO/TLB flushing code on ARM Exynos platforms"
* tag 'iommu-fixes-v4.11-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu:
iommu: Disambiguate MSI region types
iommu/exynos: Workaround FLPD cache flush issues for SYSMMU v5
iommu/exynos: Block SYSMMU while invalidating FLPD cache
iommu/vt-d: Fix NULL pointer dereference in device_to_iommu
iommu/io-pgtable-arm-v7s: Check for leaf entry before dereferencing it
iommu/io-pgtable-arm: Check for leaf entry before dereferencing it
We need to make sure that the cq work item does not
run when we are destroying the cq. Unlike flush_work,
cancel_work_sync protects against self-requeue of the
work item (which we can do in ib_cq_poll_work).
