First correct the edge case to return the last element if we're
outside the range, rather than at the last element, so that
interpolation is not omitted for points between the two last entries in
the table.
Then correct the formula to perform linear interpolation based the two
points surrounding the read ADC value. The indices for temp are kept as
"hi" and "lo" to pair with the adc indices, but there's no requirement
that the temperature is provided in descendent order. mult_frac() is
used to prevent issues with overflowing the int.

The IP can manage to trigger interrupts on overheat situation from all
the sensors.
However, the interrupt source changes along with the last selected
source (ie. the last read sensor), which is an inconsistent behavior.
Avoid possible glitches by always selecting back only one channel which
will then be referenced as the "overheat_sensor" (arbitrarily: the first
in the DT which has a critical trip point filled in).
It is possible that the scan of all thermal zone nodes did not bring a
critical trip point from which the overheat interrupt could be
configured. In this case just complain but do not fail the probe.
Also disable sensor switch during overheat situations because changing
the channel while the system is too hot could clear the overheat state
by changing the source while the temperature is still very high.
Even if the overheat state is not declared, overheat interrupt must be
cleared by reading the DFX interrupt cause _after_ the temperature has
fallen down to the low threshold, otherwise future possible interrupts
would not be served. A work polls the corresponding register until the
overheat flag gets cleared in this case.

The MSI Enable bit in the MSI Capability (PCIe r4.0, sec 7.7.1.2) controls
whether a Function can request service using MSI.
i.MX6 Root Ports implement the MSI Capability and may use MSI to request
service for events like PME, hotplug, AER, etc. In addition, on i.MX6, the
MSI Enable bit controls delivery of MSI interrupts from components below
the Root Port.
Prior to f3fdfc4ac3a2 ("PCI: Remove host driver Kconfig selection of
CONFIG_PCIEPORTBUS"), enabling CONFIG_PCI_IMX6 automatically also enabled
CONFIG_PCIEPORTBUS, and when portdrv claimed the Root Ports, it set the MSI
Enable bit so it could use PME, hotplug, AER, etc. As a side effect, that
also enabled delivery of MSI interrupts from downstream components.
The imx6q-pcie driver itself does not depend on portdrv, so set MSI Enable
in imx6q-pcie so MSI from downstream components works even if nobody uses
MSI for the Root Port events.

Pull IOMMU updates from Joerg Roedel:
- Page table code for AMD IOMMU now supports large pages where smaller
page-sizes were mapped before. VFIO had to work around that in the
past and I included a patch to remove it (acked by Alex Williamson)
- Patches to unmodularize a couple of IOMMU drivers that would never
work as modules anyway.
- Work to unify the the iommu-related pointers in 'struct device' into
one pointer. This work is not finished yet, but will probably be in
the next cycle.
- NUMA aware allocation in iommu-dma code
- Support for r8a774a1 and r8a774c0 in the Renesas IOMMU driver
- Scalable mode support for the Intel VT-d driver
- PM runtime improvements for the ARM-SMMU driver
- Support for the QCOM-SMMUv2 IOMMU hardware from Qualcom

For HNAE3_DOWN_CLIENT calling hns3_nic_net_stop(), HNAE3_UP_CLIENT
should call hns3_nic_net_open(), since if the number of queue or
the map of TC has is changed before HHAE3_UP_CLIENT is called,
it will cause problem.
Also the HNS3_NIC_STATE_RESETTING flag needs to be cleared before
hns3_nic_net_open() called, and set it back while hns3_nic_net_open()
failed.

Commit 33a48ab105a7 ("ibmveth: Fix DMA unmap error") fixed an issue in the
normal code path of ibmveth_xmit_start() that was originally introduced by
Commit 6e8ab30ec677 ("ibmveth: Add scatter-gather support"). This original
fix missed the error path where dma_unmap_page is wrongly called on the
header portion in descs[0] which was mapped with dma_map_single. As a
result a failure to DMA map any of the frags results in a dmesg warning
when CONFIG_DMA_API_DEBUG is enabled.

DMA-API: ibmveth 30000002: device driver frees DMA memory with wrong function
