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).

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).

Netdev notification events are de-registered only when all
client iwdev instances are removed. If a single client is closed
and re-opened, netdev events could arrive even before the Control
Queue-Pair (CQP) is created, causing a NULL pointer dereference crash
in i40iw_get_cqp_request. Fix this by allowing netdev event
notification only after we have reached the INET_NOTIFIER state with
respect to device initialization.

Pull power management fixes from Rafael Wysocki:
"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)"

No caller currently checks the return value of
kvm_io_bus_unregister_dev(). This is evil, as all callers silently go on
freeing their device. A stale reference will remain in the io_bus,
getting at least used again, when the iobus gets teared down on
kvm_destroy_vm() - leading to use after free errors.
There is nothing the callers could do, except retrying over and over
again.
So let's simply remove the bus altogether, print an error and make
sure no one can access this broken bus again (returning -ENOMEM on any
attempt to access it).

We should hide and forbid VPID in L1 if it is disabled on L0. However, nested VPID
enable bit is set unconditionally during setup nested vmx exec controls though VPID
is not exposed through nested VMX capablity. This patch fixes it by don't set nested
VPID enable bit if it is disabled on L0.

After async pf setup successfully, there is a broadcast wakeup w/ special
token 0xffffffff which tells vCPU that it should wake up all processes
waiting for APFs though there is no real process waiting at the moment.
The async page present tracepoint print prematurely and fails to catch the
special token setup. This patch fixes it by moving the async page present
tracepoint after the special token setup.

Quoting from the Intel SDM, volume 3, section 28.3.3.4: Guidelines for
Use of the INVEPT Instruction:
If EPT was in use on a logical processor at one time with EPTP X, it
is recommended that software use the INVEPT instruction with the
"single-context" INVEPT type and with EPTP X in the INVEPT descriptor
before a VM entry on the same logical processor that enables EPT with
EPTP X and either (a) the "virtualize APIC accesses" VM-execution
control was changed from 0 to 1; or (b) the value of the APIC-access
address was changed.
In the nested case, the burden falls on L1, unless L0 enables EPT in
vmcs02 when L1 doesn't enable EPT in vmcs12.

This was broken in commit cd979883b9ed ("xen/acpi-processor:
fix enabling interrupts on syscore_resume"). do_suspend (from
xen/manage.c) and thus xen_resume_notifier never get called on
the initial-domain at resume (it is if running as guest.)
The rationale for the breaking change was that upload_pm_data()
potentially does blocking work in syscore_resume(). This patch
addresses the original issue by scheduling upload_pm_data() to
execute in workqueue context.

Otherwise this can also prevent modesets e.g. for switching VTs, when
multiple monitors with different native resolutions are connected.
The depths must match though, so keep the != test for that.
Also update the DRM_DEBUG output to be slightly more accurate, this
doesn't only affect requests from userspace.

Disabling interrupts for even a millisecond can cause problems for some
devices. That can happen when Intel host controllers wait for the present
state to propagate.
The spin lock is not necessary here. Anything that is racing with changes
to the I/O state is already broken. The mmc core already provides
synchronization via "claiming" the host.
Although the spin lock probably should be removed from the code paths that
lead to this point, such a patch would touch too much code to be suitable
for stable trees. Consequently, for this patch, just drop the spin lock
while waiting.
