With ti-sysc driver working for most use cases, we can start converting
the omap variant SoCs to use device tree data for the interconnect target
modules instead of the legacy hwmod platform data.
We start with omap4 l4 devices excluding the ones that still depend on
a reset controller driver like DSP MMU. And we don't yet convert the l4
ABE instance as that needs a bit more work.
We also add a proper interconnect hierarchy for the devices while at it
to make further work on genpd easier and to avoid most deferred probe
issues.
At this point we are not dropping any platform data, and we initially
still use it to validate the dts data. Then in later merge cycles we
can start dropping the related platform data.

AU0828_DEVICE() macro in quirks-table.h uses USB_DEVICE_VENDOR_SPEC()
for expanding idVendor and idProduct fields. However, the latter
macro adds also match_flags and bInterfaceClass, which are different
from the values AU0828_DEVICE() macro sets after that.
For fixing them, just expand idVendor and idProduct fields manually in
AU0828_DEVICE().

One place in cs5535audio_build_dma_packets() does an extra conversion
via cpu_to_le32(); namely jmpprd_addr is passed to setup_prd() ops,
which writes the value via cs_writel(). That is, the callback does
the conversion by itself, and we don't need to convert beforehand.

Commit 1e175d2 ("KVM: PPC: Book3S HV: Pack VCORE IDs to access full
VCPU ID space", 2018-07-25) added code that uses kvm->arch.emul_smt_mode
before any VCPUs are created. However, userspace can change
kvm->arch.emul_smt_mode at any time up until the first VCPU is created.
Hence it is (theoretically) possible for the check in
kvmppc_core_vcpu_create_hv() to race with another userspace thread
changing kvm->arch.emul_smt_mode.
This fixes it by moving the test that uses kvm->arch.emul_smt_mode into
the block where kvm->lock is held.

SMC code uses the base gid for VLAN traffic. The gids exchanged in
the CLC handshake and the gid index used for the QP have to switch
from the base gid to the appropriate vlan gid.
When searching for a matching IB device port for a certain vlan
device, it does not make sense to return an IB device port, which
is not enabled for the used vlan_id. Add another check whether a
vlan gid exists for a certain IB device port.

nfp: protect from theoretical size overflows and SR-IOV errors
This small set changes the handling of pci_sriov_set_totalvfs() errors.
nfp is the only driver which fails probe on pci_sriov_set_totalvfs()
errors. It turns out some BIOS configurations may break SR-IOV and
users who don't use that feature should not suffer.
Remaining patches makes sure we use overflow-safe function for ring
allocation, even though ring sizes are limited. It won't hurt and
we can also enable fallback to vmalloc() if memory is tight while
at it.

On machines with buggy ACPI tables or when SR-IOV is already enabled
we may not be able to set the SR-IOV VF limit in sysfs, it's not fatal
because the limit is imposed by the driver anyway. Only the sysfs
'sriov_totalvfs' attribute will be too high. Print an error to inform
user about the failure but allow probe to continue.

Commit 1e175d2 ("KVM: PPC: Book3S HV: Pack VCORE IDs to access full
VCPU ID space", 2018-07-25) allowed use of VCPU IDs up to
KVM_MAX_VCPU_ID on POWER9 in all guest SMT modes and guest emulated
hardware SMT modes. However, with the current definition of
KVM_MAX_VCPU_ID, a guest SMT mode of 1 and an emulated SMT mode of 8,
it is only possible to create KVM_MAX_VCPUS / 2 VCPUS, because
threads_per_subcore is 4 on POWER9 CPUs. (Using an emulated SMT mode
of 8 is useful when migrating VMs to or from POWER8 hosts.)
This increases KVM_MAX_VCPU_ID to 8 * KVM_MAX_VCPUS when HV KVM is
configured in, so that a full complement of KVM_MAX_VCPUS VCPUs can
be created on POWER9 in all guest SMT modes and emulated hardware
SMT modes.
