Pull mod_devicetable.h header split from Uwe Kleine-König:
 "Split &lt;linux/mod_devicetable.h&gt; in per subsystem headers

  &lt;linux/mod_devicetable.h&gt; is included transitively in nearly every
  driver in an x86_64 allmodconfig build of v7.1:

      $ find drivers -name \*.o -not -name \*.mod.o | wc -l
      21330
      $ find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l mod_devicetable.h | wc -l
      17038

  The result of this mixture of different and unrelated subsystem
  details is that even when touching an obscure device id struct most of
  the kernel needs to be recompiled. Given that each driver typically
  only needs one or two of these structures, splitting into per
  subsystem headers and only including what is really needed reduces the
  amount of needed recompilation.

  This split is implemented in the first commit and then after some
  preparatory work in the following commits, the last two replace
  includes of &lt;linux/mod_devicetable.h&gt; by the actually needed more
  specific headers.

  There are still a few instances left, but the ones with high impact
  (that is in headers that are used a lot) and the easy ones (.c files)
  are handled. These remaining includes will be addressed during the
  next merge window"

<title>bpf: Restrict JIT predictor flush to cBPF</title>

Currently predictor flush on memory reuse is done for all BPF JIT
allocations, but only cBPF programs can be loaded by an unprivileged user.
eBPF is privileged by default, and flushing predictors for all CPUs on
every eBPF reuse penalizes the common case for no security benefit.

eBPF allocations can be frequent on busy systems, only flush predictors
for cBPF programs. Trampoline and dispatcher allocations also skip the
flush as they are eBPF-only.

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Remove MPS/MRRS Kconfig settings (CONFIG_PCIE_BUS_*) that worked
     around a WiFi device defect; use a quirk or boot-time
     "pci=pcie_bus_tune_*" kernel parameter instead (Bjorn Helgaas)

   - Always lift 2.5GT/s restriction in PCIe failed link retraining to
     avoid clamping a link to 2.5GT/s after hot-plug changes the device
     (Maciej W. Rozycki)

   - Request bus reassignment when not probe-only to fix an enumeration
     regression on Marvell CN106XX and possibly other DT-based systems
     (Ratheesh Kannoth)

   - Fix procfs race between pci_proc_init() and pci_bus_add_device()
     that resulted in 'proc_dir_entry ... already registered' warnings
     and pointer corruption (Krzysztof Wilczyński)

   - Fix sysfs race that causes 'duplicate filename' warnings and boot
     panics by converting PCI resource files to static attributes
     (Krzysztof Wilczyński)

   - Expose sysfs 'resourceN_resize' attributes only on platforms with
     PCI mmap (Krzysztof Wilczyński)

   - Require CAP_SYS_ADMIN to write to sysfs 'resourceN_resize'
     attributes (Krzysztof Wilczyński)

   - Add security_locked_down(LOCKDOWN_PCI_ACCESS) to alpha PCI resource
     mmap path to match the generic path (Krzysztof Wilczyński)

   - Use kstrtobool() to parse the 'rom' attribute input to avoid the
     unexpected behavior of enabling the ROM when writing '0' with no
     trailing newline (Krzysztof Wilczyński)

  Resource management:

   - Improve resource claim logging for debuggability (Ilpo Järvinen)

   - Clean up several uses of const parameters (Ilpo Järvinen)

   - Check option ROM header signatures and lengths before accessing to
     avoid page faults and alignment faults (Guixin Liu)

  ASPM:

   - Don't reconfigure ASPM when entering low-power D-state; only do it
     when returning back to D0 (Carlos Bilbao)

  Power management:

   - During suspend, set power state to 'unknown' for all devices, not
     just those with drivers (Lukas Wunner)

   - Skip restoring Resizable BARs and VF Resizable BARs if device
     doesn't respond to config reads, to avoid invalid array accesses
     (Marco Nenciarini)

   - Add pci_suspend_retains_context() so drivers can tell whether
     devices retain internal state across suspend/resume, since some
     platforms reset devices on suspend; use this in nvme to avoid
     issues on Qcom RCs (Manivannan Sadhasivam)

  Power control:

   - Only to power on/off devices that actually support power control to
     avoid poking at incompatible devices mentioned in DT (Manivannan
     Sadhasivam)

  Virtualization and resets:

   - Log device readiness timeouts as errors, not warnings, because the
     device is likely unusable in this case (Bjorn Helgaas)

   - Wait for device readiness after soft reset (D3hot -&gt;
     D0uninitialized transition), when the device may respond with
     Request Retry Status (RRS) if it needs more time to initialize
     (Bjorn Helgaas)

   - Drop unnecessary retries when restoring BARs because resets should
     now already include all required delays (Lukas Wunner)

   - Avoid FLR for MediaTek MT7925 WiFi, where FLR fails after a VM
     terminates uncleanly (Jose Ignacio Tornos Martinez)

   - Avoid SBR for Qualcomm WCN6855/WCN7850 WiFi, SDX62/SDX65 modems,
     which seem not to support it correctly (Jose Ignacio Tornos
     Martinez)

  Peer-to-peer DMA:

   - Prevent P2PDMA as well as CPU access to non-mappable BARs, e.g.,
     s390 ISM BARs (Matt Evans)

   - Add Intel QAT, DSA, IAA devices to whitelist (Lukas Wunner)

  Endpoint framework:

   - Add endpoint controller APIs for use by function drivers to
     discover auxiliary blocks like DMA engines (Koichiro Den)

   - Remember DesignWare eDMA engine base/size and expose them via the
     EPC aux-resource API (Koichiro Den)

   - Add endpoint embedded doorbell fallback, used if MSI allocation
     fails (Koichiro Den)

   - Validate BAR index and remove dead BAR read in endpoint doorbell
     test (Carlos Bilbao)

   - Unwind MSI/MSI-X vectors if NTB initialization fails part-way
     through (Koichiro Den)

   - Cache sleepable pci_irq_vector() value at ISR setup to avoid
     calling it from hardirq context (Koichiro Den)

   - Call sleepable pci_epc_raise_irq() from a work item instead of
     atomic context, e.g., when setting bits in NTB peer doorbells in
     the ntb_peer_db_set() path (Koichiro Den)

   - Report 0-based vNTB doorbell vector to account for link event 0 and
     historically skipped slot 1 (Koichiro Den)

   - Prevent configfs writes to vNTB db_count and other values that are
     already in use after EPC attach (Koichiro Den)

   - Account for vNTB db_valid reserved slots (link event 0 and
     historically skipped slot 1) so they don't appear as valid
     doorbells (Koichiro Den)

   - Implement vNTB .db_vector_count()/mask() for doorbells so clients
     can use multiple vectors and avoid thundering herds (Koichiro Den)

   - Report 0-based NTB doorbell vector to account for link event 0 and
     historically skipped slot 1 (Koichiro Den)

   - Fix doorbell bitmask and IRQ vector handling to clear only
     specified bits, use the correct vector for non-contiguous Linux IRQ
     numbers, and validate incoming vectors (Koichiro Den)

   - Implement NTB .db_vector_count()/mask() for doorbells so clients
     can use multiple vectors (Koichiro Den)

  Native PCIe controller infrastructure:

   - Add pci_host_common_link_train_delay() for the mandatory delay
     after &gt; 5GT/s Link training completes and use it for cadence HPA,
     j721e, LGA; dwc; aardvark, mediatek-gen3, rzg3s (Hans Zhang)

   - Protect root bus removal with rescan lock in altera, brcmstb,
     cadence, dwc, iproc, mediatek, plda, rockchip to prevent
     use-after-free or crashes when racing with sysfs rescan or hotplug
     (Hans Zhang)

   - Add pci_host_common_parse_ports() for use by any native driver to
     parse Root Port properties (per-Link features like width, speed,
     PHY, power and reset control, etc should be described in Root Port
     stanzas, not the host bridge; currently only reset GPIOs
     implemented) (Sherry Sun)

  New native PCIe controller drivers:

   - Add DT binding and driver for UltraRISC DP1000 PCIe controller
     (Xincheng Zhang, Jia Wang)

  Altera PCIe controller driver:

   - Do not dispose of the parent IRQ mapping, which belongs to the
     parent interrupt controller (Mahesh Vaidya)

   - Fix chained IRQ handler ordering issue and resource leaks on probe
     failure (Mahesh Vaidya)

  AMD MDB PCIe controller driver:

   - Assert PERST# on shutdown so any connected Endpoints are held in
     reset during shutdown (Sai Krishna Musham)

  Amlogic Meson PCIe controller driver:

   - Propagate devm_add_action_or_reset() failure to fix probe error
     path (Shuvam Pandey)

   - Add .remove() callback to deinitialize the host bridge and power
     off the PHY (Shuvam Pandey)

  Broadcom iProc PCIe controller driver:

   - Restore .map_irq() assignment; its removal broke INTx on the iproc
     platform bus driver (Mark Tomlinson)

  Broadcom STB PCIe controller driver:

   - No change, but products using certain WiFi devices may be affected
     by removal of CONFIG_PCIE_BUS_* (see above)

  Freescale i.MX6 PCIe controller driver:

   - Move IMX6SX_GPR12_PCIE_TEST_POWERDOWN handling into the core reset
     functions (Richard Zhu)

   - Assert PERST# before enabling regulators to ensure that even if
     power is enabled, endpoint stays inactive until REFCLK is stable
     (Sherry Sun)

   - Parse reset properties in Root Port nodes (falling back to host
     bridge) to help support Key E connectors and the pwrctrl framework
     (Sherry Sun)

   - Configure i.MX95 REF_USE_PAD before PHY reset (Richard Zhu)

   - Assert i.MX95 ref_clk_en after reference clock stabilizes (Richard
     Zhu)

   - Integrate new pwrctrl API for DTs with Root Port-level power
     supplies (Sherry Sun)

  Intel Gateway PCIe controller driver:

   - Enable clock before PHY init for correct ordering (Florian Eckert)

   - Add .start_link() callback so the driver works again (Florian
     Eckert)

   - Stop overwriting the ATU base address discovered by
     dw_pcie_get_resources() (Florian Eckert)

   - Add DT 'atu' region since this is hardware-specific, and fall back
     to driver default if lacking (Florian Eckert)

  Loongson PCIe controller driver:

   - Ignore downstream devices only on internal bridges to avoid
     Loongson hardware issue (Rong Zhang)

   - Quirk old Loongson-3C6000 bridges that advertise incorrect
     supported link speeds (Ziyao Li)

  Marvell MVEBU PCIe controller driver:

   - Use fixed-width interrupt masks to avoid truncation in 64-bit
     builds (Rosen Penev)

  MediaTek PCIe controller driver:

   - Use FIELD_PREP() to fix incorrect operator precedence in
     PCIE_FTS_NUM_L0 (Li RongQing)

   - Fix IRQ domain leak when port fails to enable (Manivannan
     Sadhasivam)

   - Use actual physical address for MSI message address instead of
     virt_to_phys() (Manivannan Sadhasivam)

   - Add EcoNet EN7528 to DT binding (Caleb James DeLisle)

  MediaTek PCIe Gen3 controller driver:

   - Deassert PCIE_PHY_RSTB so REFCLK is stable for at least 100ms
     (PCIE_T_PVPERL_MS) before deasserting PERST# (Jian Yang)

   - Add .shutdown() to assert PERST# before powering down device (Jian
     Yang)

   - Do full device power down on removal, including asserting PERST#,
     when removing driver (Chen-Yu Tsai)

   - Fix a 'failed to create pwrctrl devices' error message that was
     inadvertently skipped (Chen-Yu Tsai)

  NVIDIA Tegra194 PCIe controller driver:

   - Program the DesignWare PORT_AFR L1 entrance latency based on the
     'aspm-l1-entry-delay-ns' DT property (Manikanta Maddireddy)

  Qualcomm PCIe controller driver:

   - Add Eliza SoC compatible in DT binding (Krishna Chaitanya Chundru)

   - Set max OPP during resume so DBI register accesses don't fail with
     NoC errors (Qiang Yu)

   - Add pci_host_common_d3cold_possible() to determine whether
     downstream devices are already in D3hot and wakeup-enabled devices
     are capable of generating PME from D3cold (Krishna Chaitanya
     Chundru)

   - Add .get_ltssm() callback to get the LTSSM status without DBI,
     since DBI may be inaccessible after PME_Turn_Off (Krishna Chaitanya
     Chundru)

   - Power down PHY via PARF_PHY_CTRL before disabling rails/clocks to
     avoid power leakage (Krishna Chaitanya Chundru)

   - Decide whether suspend should put the link in L2 and power down
     using pci_host_common_d3cold_possible() instead of checking whether
     ASPM L1 is enabled (Krishna Chaitanya Chundru)

   - Add qcom D3cold support to tear down interconnect bandwidth and OPP
     votes (Krishna Chaitanya Chundru)

   - Use common struct dw_pcie 'mode' rather than duplicating it in
     artpec6, dra7xx, dwc-pcie, and keembay driver structs (Hans Zhang)

   - Use DEFINE_SHOW_ATTRIBUTE for ltssm_status debugfs to reduce
     boilerplate and fix a seq_file memory leak by including a
     .release() callback (Hans Zhang)

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Remove MPS/MRRS Kconfig settings (CONFIG_PCIE_BUS_*) that worked
     around a WiFi device defect; use a quirk or boot-time
     "pci=pcie_bus_tune_*" kernel parameter instead (Bjorn Helgaas)

   - Always lift 2.5GT/s restriction in PCIe failed link retraining to
     avoid clamping a link to 2.5GT/s after hot-plug changes the device
     (Maciej W. Rozycki)

   - Request bus reassignment when not probe-only to fix an enumeration
     regression on Marvell CN106XX and possibly other DT-based systems
     (Ratheesh Kannoth)

   - Fix procfs race between pci_proc_init() and pci_bus_add_device()
     that resulted in 'proc_dir_entry ... already registered' warnings
     and pointer corruption (Krzysztof Wilczyński)

   - Fix sysfs race that causes 'duplicate filename' warnings and boot
     panics by converting PCI resource files to static attributes
     (Krzysztof Wilczyński)

   - Expose sysfs 'resourceN_resize' attributes only on platforms with
     PCI mmap (Krzysztof Wilczyński)

   - Require CAP_SYS_ADMIN to write to sysfs 'resourceN_resize'
     attributes (Krzysztof Wilczyński)

   - Add security_locked_down(LOCKDOWN_PCI_ACCESS) to alpha PCI resource
     mmap path to match the generic path (Krzysztof Wilczyński)

   - Use kstrtobool() to parse the 'rom' attribute input to avoid the
     unexpected behavior of enabling the ROM when writing '0' with no
     trailing newline (Krzysztof Wilczyński)

  Resource management:

   - Improve resource claim logging for debuggability (Ilpo Järvinen)

   - Clean up several uses of const parameters (Ilpo Järvinen)

   - Check option ROM header signatures and lengths before accessing to
     avoid page faults and alignment faults (Guixin Liu)

  ASPM:

   - Don't reconfigure ASPM when entering low-power D-state; only do it
     when returning back to D0 (Carlos Bilbao)

  Power management:

   - During suspend, set power state to 'unknown' for all devices, not
     just those with drivers (Lukas Wunner)

   - Skip restoring Resizable BARs and VF Resizable BARs if device
     doesn't respond to config reads, to avoid invalid array accesses
     (Marco Nenciarini)

   - Add pci_suspend_retains_context() so drivers can tell whether
     devices retain internal state across suspend/resume, since some
     platforms reset devices on suspend; use this in nvme to avoid
     issues on Qcom RCs (Manivannan Sadhasivam)

  Power control:

   - Only to power on/off devices that actually support power control to
     avoid poking at incompatible devices mentioned in DT (Manivannan
     Sadhasivam)

  Virtualization and resets:

   - Log device readiness timeouts as errors, not warnings, because the
     device is likely unusable in this case (Bjorn Helgaas)

   - Wait for device readiness after soft reset (D3hot -&gt;
     D0uninitialized transition), when the device may respond with
     Request Retry Status (RRS) if it needs more time to initialize
     (Bjorn Helgaas)

   - Drop unnecessary retries when restoring BARs because resets should
     now already include all required delays (Lukas Wunner)

   - Avoid FLR for MediaTek MT7925 WiFi, where FLR fails after a VM
     terminates uncleanly (Jose Ignacio Tornos Martinez)

   - Avoid SBR for Qualcomm WCN6855/WCN7850 WiFi, SDX62/SDX65 modems,
     which seem not to support it correctly (Jose Ignacio Tornos
     Martinez)

  Peer-to-peer DMA:

   - Prevent P2PDMA as well as CPU access to non-mappable BARs, e.g.,
     s390 ISM BARs (Matt Evans)

   - Add Intel QAT, DSA, IAA devices to whitelist (Lukas Wunner)

  Endpoint framework:

   - Add endpoint controller APIs for use by function drivers to
     discover auxiliary blocks like DMA engines (Koichiro Den)

   - Remember DesignWare eDMA engine base/size and expose them via the
     EPC aux-resource API (Koichiro Den)

   - Add endpoint embedded doorbell fallback, used if MSI allocation
     fails (Koichiro Den)

   - Validate BAR index and remove dead BAR read in endpoint doorbell
     test (Carlos Bilbao)

   - Unwind MSI/MSI-X vectors if NTB initialization fails part-way
     through (Koichiro Den)

   - Cache sleepable pci_irq_vector() value at ISR setup to avoid
     calling it from hardirq context (Koichiro Den)

   - Call sleepable pci_epc_raise_irq() from a work item instead of
     atomic context, e.g., when setting bits in NTB peer doorbells in
     the ntb_peer_db_set() path (Koichiro Den)

   - Report 0-based vNTB doorbell vector to account for link event 0 and
     historically skipped slot 1 (Koichiro Den)

   - Prevent configfs writes to vNTB db_count and other values that are
     already in use after EPC attach (Koichiro Den)

   - Account for vNTB db_valid reserved slots (link event 0 and
     historically skipped slot 1) so they don't appear as valid
     doorbells (Koichiro Den)

   - Implement vNTB .db_vector_count()/mask() for doorbells so clients
     can use multiple vectors and avoid thundering herds (Koichiro Den)

   - Report 0-based NTB doorbell vector to account for link event 0 and
     historically skipped slot 1 (Koichiro Den)

   - Fix doorbell bitmask and IRQ vector handling to clear only
     specified bits, use the correct vector for non-contiguous Linux IRQ
     numbers, and validate incoming vectors (Koichiro Den)

   - Implement NTB .db_vector_count()/mask() for doorbells so clients
     can use multiple vectors (Koichiro Den)

  Native PCIe controller infrastructure:

   - Add pci_host_common_link_train_delay() for the mandatory delay
     after &gt; 5GT/s Link training completes and use it for cadence HPA,
     j721e, LGA; dwc; aardvark, mediatek-gen3, rzg3s (Hans Zhang)

   - Protect root bus removal with rescan lock in altera, brcmstb,
     cadence, dwc, iproc, mediatek, plda, rockchip to prevent
     use-after-free or crashes when racing with sysfs rescan or hotplug
     (Hans Zhang)

   - Add pci_host_common_parse_ports() for use by any native driver to
     parse Root Port properties (per-Link features like width, speed,
     PHY, power and reset control, etc should be described in Root Port
     stanzas, not the host bridge; currently only reset GPIOs
     implemented) (Sherry Sun)

  New native PCIe controller drivers:

   - Add DT binding and driver for UltraRISC DP1000 PCIe controller
     (Xincheng Zhang, Jia Wang)

  Altera PCIe controller driver:

   - Do not dispose of the parent IRQ mapping, which belongs to the
     parent interrupt controller (Mahesh Vaidya)

   - Fix chained IRQ handler ordering issue and resource leaks on probe
     failure (Mahesh Vaidya)

     path (Shuvam Pandey)

   - Add .remove() callback to deinitialize the host bridge and power

  Broadcom iProc PCIe controller driver:

   - Restore .map_irq() assignment; its removal broke INTx on the iproc
     platform bus driver (Mark Tomlinson)

  Broadcom STB PCIe controller driver:

   - No change, but products using certain WiFi devices may be affected
     by removal of CONFIG_PCIE_BUS_* (see above)

  Freescale i.MX6 PCIe controller driver:

   - Move IMX6SX_GPR12_PCIE_TEST_POWERDOWN handling into the core reset
     functions (Richard Zhu)

   - Assert PERST# before enabling regulators to ensure that even if
     power is enabled, endpoint stays inactive until REFCLK is stable
     (Sherry Sun)

   - Parse reset properties in Root Port nodes (falling back to host
     bridge) to help support Key E connectors and the pwrctrl framework
     (Sherry Sun)

   - Configure i.MX95 REF_USE_PAD before PHY reset (Richard Zhu)

   - Assert i.MX95 ref_clk_en after reference clock stabilizes (Richard

     Eckert)

   - Stop overwriting the ATU base address discovered by
     dw_pcie_get_resources() (Florian Eckert)

   - Add DT 'atu' region since this is hardware-specific, and fall back
     to driver default if lacking (Florian Eckert)

   - Ignore downstream devices only on internal bridges to avoid
     Loongson hardware issue (Rong Zhang)

   - Quirk old Loongson-3C6000 bridges that advertise incorrect
     supported link speeds (Ziyao Li)

  Marvell MVEBU PCIe controller driver:

   - Use fixed-width interrupt masks to avoid truncation in 64-bit
     builds (Rosen Penev)

  MediaTek PCIe controller driver:

   - Use FIELD_PREP() to fix incorrect operator precedence in
     PCIE_FTS_NUM_L0 (Li RongQing)

   - Fix IRQ domain leak when port fails to enable (Manivannan
     Sadhasivam)

   - Use actual physical address for MSI message address instead of
     virt_to_phys() (Manivannan Sadhasivam)

   - Add EcoNet EN7528 to DT binding (Caleb James DeLisle)

  MediaTek PCIe Gen3 controller driver:

   - Deassert PCIE_PHY_RSTB so REFCLK is stable for at least 100ms

   - Add Eliza SoC compatible in DT binding (Krishna Chaitanya Chundru)

   - Set max OPP during resume so DBI register accesses don't fail with
     NoC errors (Qiang Yu)

   - Add pci_host_common_d3cold_possible() to determine whether
     downstream devices are already in D3hot and wakeup-enabled devices
     are capable of generating PME from D3cold (Krishna Chaitanya
     Chundru)

   - Add .get_ltssm() callback to get the LTSSM status without DBI,
     since DBI may be inaccessible after PME_Turn_Off (Krishna Chaitanya
     Chundru)

   - Power down PHY via PARF_PHY_CTRL before disabling rails/clocks to
     avoid power leakage (Krishna Chaitanya Chundru)

     using pci_host_common_d3cold_possible() instead of checking whether
     ASPM L1 is enabled (Krishna Chaitanya Chundru)

   - Add qcom D3cold support to tear down interconnect bandwidth and OPP
     votes (Krishna Chaitanya Chundru)

Currently, legacy_io and legacy_mem are dynamically allocated and created
by pci_create_legacy_files(), with pci_adjust_legacy_attr() updating the
attributes at runtime on Alpha to rename them and shift the size for sparse
addressing.

Convert to four static const attributes (legacy_io, legacy_io_sparse,
legacy_mem, legacy_mem_sparse) with .is_bin_visible() callbacks that use
pci_legacy_has_sparse() to select the appropriate variant per bus.  The
sizes are compile-time constants and .size is set directly on each
attribute.

Register the groups in pcibus_groups[] under a HAVE_PCI_LEGACY guard so the
driver model handles creation and removal automatically.

Stub out pci_create_legacy_files() and pci_remove_legacy_files() as the
dynamic creation is no longer needed.  Remove the __weak
pci_adjust_legacy_attr(), Alpha's override, and its declaration from both
Alpha and PowerPC asm/pci.h headers.

pci_sriov_resource_alignment() inputs struct pci_dev which it should not
need to alter to calculate alignment.

Make pci_dev pci_sriov_resource_alignment() inputs const. It requires
making pci_iov_resource_size() input const as well.

pci_sriov_resource_alignment() inputs struct pci_dev which it should not
need to alter to calculate alignment.

Make pci_dev pci_sriov_resource_alignment() inputs const. It requires
making pci_iov_resource_size() input const as well.

Convert input pci_dev for pseries_get_iov_fw_value() and pnv_iov_get() to
const to be able to convert pcibios_iov_resource_alignment() as well in an
upcoming change.

Pull tty / serial driver updates from Greg KH:
 "Here is the big set of TTY and Serial driver updates for 7.2-rc1.

  Overall we end up removing more code than added, due to an obsolete

  Other than that driver removal, major things included in here are:

   - max310x serial driver updates and fixes

   - 8250 driver updates and rework in places to make it more "modern"

   - dts file updates

   - serial driver core tweaks and updates

   - vt code cleanups

   - vc_screen crash fixes
