IB/device: Convert ib-comp-wq to be CPU-bound
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.

infiniband: Fix alignment of mmap cookies to support VIPT caching
When vmalloc_user is used to create memory that is supposed to be mmap'd
to user space, it is necessary for the mmap cookie (eg the offset) to be
aligned to SHMLBA.
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).

"One of these is an intel_pstate regression fix and it is not a small
change, but it mostly removes code that shouldn't be there. That code
was acquired by mistake and has been a source of constant pain since
then, so the time has come to get rid of it finally. We have not seen
problems with this change in the lab, so fingers crossed.
The rest is more usual: one more intel_pstate commit removing useless
code, a cpufreq core fix to make it restore policy limits on CPU
online (which prevents the limits from being reset over system
suspend/resume), a schedutil cpufreq governor initialization fix to
make it actually work as advertised on all systems and an extra sanity
check in the cpuidle core to prevent crashes from happening if the
arch code messes things up.
Specifics:
- Make intel_pstate use one set of global P-state limits in the
active mode regardless of the scaling_governor settings for
individual CPUs instead of switching back and forth between two of
them in a way that is hard to control (Rafael Wysocki).
- Drop a useless function from intel_pstate to prevent it from
modifying the maximum supported frequency value unexpectedly which
may confuse the cpufreq core (Rafael Wysocki).
- Fix the cpufreq core to restore policy limits on CPU online so that
the limits are not reset over system suspend/resume, among other
things (Viresh Kumar).
- Fix the initialization of the schedutil cpufreq governor to make
the IO-wait boosting mechanism in it actually work on systems with
one CPU per cpufreq policy (Rafael Wysocki).
- Add a sanity check to the cpuidle core to prevent crashes from
happening if the architecture code initialization fails to set up
things as expected (Vaidyanathan Srinivasan)"
