Extend devm_of_pci_get_host_bridge_resources() and
pci_parse_request_of_pci_ranges() helpers to also parse the inbound
addresses from DT 'dma-ranges' and populate a resource list with the
translated addresses. This will help ensure 'dma-ranges' is always
parsed in a consistent way.

VMD bus restrictions are required when IO fabric is multiplexed such
that VMD cannot use the entire bus range. This patch adds another bus

Linux-next commit titled "perf/core: Optimize perf_init_event()"
changed the semantics of PMU device driver registration.
It was done to speed up the lookup/handling of PMU device driver
specific events. It also enforces that only one PMU device
driver will be registered of type PERF_EVENT_RAW.
This change added these line in function perf_pmu_register():
...
+ ret = idr_alloc(&pmu_idr, pmu, max, 0, GFP_KERNEL);
+ if (ret < 0)
goto free_pdc;
+
+ WARN_ON(type >= 0 && ret != type);
The warn_on generates a message. We have 3 PMU device drivers,
each registered as type PERF_TYPE_RAW.
The cf_diag device driver (arch/s390/kernel/perf_cpumf_cf_diag.c)
always hits the WARN_ON because it is the second PMU device driver
(after sampling device driver arch/s390/kernel/perf_cpumf_sf.c)
which is registered as type 4 (PERF_TYPE_RAW).
So when the sampling device driver is registered, ret has value 4.
When cf_diag device driver is registered with type 4,
ret has value of 5 and WARN_ON fires.
Adjust the PMU device drivers for s390 to support the new
semantics required by perf_pmu_register().

This allows the of_devlink feature to work across i2c devices too. This
avoid unnecessary probe deferrals of i2c devices, defers consumers of
i2c devices till the i2c devices probe, and allows i2c drivers to
implement sync_state() callbacks.

Commit a753bfcfdb1f ("intel_th: Make the switch allocate its subdevices")
factored out intel_th_subdevice_alloc() from intel_th_populate(), but got
the error path wrong, resulting in two instances of a double put_device()
on a freshly initialized, but not 'added' device.
Fix this by only doing one put_device() in the error path.

First of all there is no need to guard GPIO request by CONFIG_OF.
It works for everybody independently on resource provider. While here,
rename the function to reflect the above.
Moreover, since we have a global dependency to OF, the rest of
conditional compilation is no-op, i.e. it's always be true.
Due to above drop useless #ifdef CONFIG_OF and therefore dead code.

Since commit 1313cc2bd8f6 ("kvm: mmu: Add guest_mode to kvm_mmu_page_role"),
guest_mode was added to mmu-role and therefore if L0 use EPT, it will
always run L1 and L2 with different EPTP. i.e. EPTP01!=EPTP02.
Because TLB entries are tagged with EP4TA, KVM can assume
TLB entries populated while running L2 are tagged differently
than TLB entries populated while running L1.
Therefore, update nested_has_guest_tlb_tag() to consider if
L0 use EPT instead of if L1 use EPT.
