It's only valid on Intel systems with the Intel VSEC.
Use dev_is_removable() instead. This should do the right
thing regardless of the platform.

The ATRM ACPI method is for fetching the dGPU vbios rom
image on laptops and all-in-one systems. It should not be
used for external add in cards. If the dGPU is thunderbolt
connected, don't try ATRM.
v2: pci_is_thunderbolt_attached only works for Intel. Use
pdev->external_facing instead.
v3: dev_is_removable() seems to be what we want

This reverts commit 84ee19bffc9306128cd0f1c650e89767079efeff.
The commit above made quirks with an OEMID fail to be applied, as they
were checking card->cid.oemid for the full 16 bits defined in MMC_FIXUP
macros but the field would only contain the bottom 8 bits.
eMMC v5.1A might have bogus values in OEMID's higher bits so another fix
will be made, but it has been decided to revert this until that is ready.

From XGMAC Core 3.20 and later, each Flexible PPS has individual PPSEN bit
to select Fixed mode or Flexible mode. The PPSEN must be set, or it stays
in Fixed PPS mode by default.

read-only reserved, and they are already in Flexible mode by default, our
new code always set PPSEN{1,2,3} do not make things worse ;-)

Pull sh updates from John Paul Adrian Glaubitz:
"While the previously announced patch series for converting arch/sh to
device trees is not yet ready for inclusion to mainline and therefore
didn't make it for this pull request, there are still a small number
changes for v6.7 which include one platform (board plus CPU and driver
code) removal plus two fixes.
The removal sent in by Arnd Bergmann concerns the microdev board which
was an early SuperH prototype board that was never used in production.
With the board removed, we were able to drop the now unused code for
the SH4-202 CPU and well as the driver code for the superhyway bus and
a custom implementation for ioport_map() and ioport_unmap() which will
allow us to simplify ioport handling in the future.
Another patch set by Geert Uytterhoeven revives SuperH BIOS
earlyprintk support which got accidentally disabled in
e76fe57447e88916 ("sh: Remove old early serial console code V2"), the
second patch in the series updates the documentation.

the kernel test robot which uncovered that arch/sh is not implementing

instead"

- Add a .write_dbi2() callback so DBI2 register writes, e.g., for

Native CXL protocol errors are delivered to the OS through AER
reporting. The owner of AER owns CXL Protocol error management with
respect to _OSC negotiation.[1] CXL device errors are handled by a
separate interrupt with native control gated by _OSC control field
'CXL Memory Error Reporting Control'.
The CXL driver incorrectly checks for 'CXL Memory Error Reporting
Control' before accessing AER registers and caching RCH downport
AER registers. Replace the current check in these 2 cases with
native AER checks.

Sami Tolvanen <samitolvanen@google.com> says:
This series adds Shadow Call Stack (SCS) support for RISC-V. SCS
uses compiler instrumentation to store return addresses in a
separate shadow stack to protect them against accidental or
malicious overwrites. More information about SCS can be found
here:
https://clang.llvm.org/docs/ShadowCallStack.html
Patch 1 is from Deepak, and it simplifies VMAP_STACK overflow
handling by adding support for accessing per-CPU variables
directly in assembly. The patch is included in this series to
make IRQ stack switching cleaner with SCS, and I've simply
rebased it and fixed a couple of minor issues. Patch 2 uses this
functionality to clean up the stack switching by moving duplicate
code into a single function. On RISC-V, the compiler uses the
gp register for storing the current shadow call stack pointer,
which is incompatible with global pointer relaxation. Patch 3
moves global pointer loading into a macro that can be easily
disabled with SCS. Patch 4 implements SCS register loading and
switching, and allows the feature to be enabled, and patch 5 adds
separate per-CPU IRQ shadow call stacks when CONFIG_IRQ_STACKS is
enabled. Patch 6 fixes the backward-edge CFI test in lkdtm for
RISC-V.
Note that this series requires Clang 17. Earlier Clang versions
support SCS on RISC-V, but use the x18 register instead of gp,
which isn't ideal. gcc has SCS support for arm64, but I'm not
aware of plans to support RISC-V. Once the Zicfiss extension is
ratified, it's probably preferable to use hardware-backed shadow
stacks instead of SCS on hardware that supports the extension,
and we may want to consider implementing CONFIG_DYNAMIC_SCS to
patch between the implementation at runtime (similarly to the
arm64 implementation, which switches to SCS when hardware PAC
support isn't available).

When LAN9303 is MDIO-connected two callchains exist into
mdio->bus->write():
1. switch ports 1&2 ("physical" PHYs):
virtual (switch-internal) MDIO bus (lan9303_switch_ops->phy_{read|write})->
lan9303_mdio_phy_{read|write} -> mdiobus_{read|write}_nested
2. LAN9303 virtual PHY:
virtual MDIO bus (lan9303_phy_{read|write}) ->
lan9303_virt_phy_reg_{read|write} -> regmap -> lan9303_mdio_{read|write}
If the latter functions just take
mutex_lock(&sw_dev->device->bus->mdio_lock) it triggers a LOCKDEP
false-positive splat. It's false-positive because the first
mdio_lock in the second callchain above belongs to virtual MDIO bus, the
second mdio_lock belongs to physical MDIO bus.
Consequent annotation in lan9303_mdio_{read|write} as nested lock
(similar to lan9303_mdio_phy_{read|write}, it's the same physical MDIO bus)
prevents the following splat:

Pull sysctl updates from Luis Chamberlain:
"To help make the move of sysctls out of kernel/sysctl.c not incur a
size penalty sysctl has been changed to allow us to not require the
sentinel, the final empty element on the sysctl array. Joel Granados
has been doing all this work. On the v6.6 kernel we got the major
infrastructure changes required to support this. For v6.7-rc1 we have
all arch/ and drivers/ modified to remove the sentinel. Both arch and
driver changes have been on linux-next for a bit less than a month. It
is worth re-iterating the value:
- this helps reduce the overall build time size of the kernel and run
time memory consumed by the kernel by about ~64 bytes per array
- the extra 64-byte penalty is no longer inncurred now when we move
sysctls out from kernel/sysctl.c to their own files
For v6.8-rc1 expect removal of all the sentinels and also then the
unneeded check for procname == NULL.
The last two patches are fixes recently merged by Krister Johansen
which allow us again to use softlockup_panic early on boot. This used
to work but the alias work broke it. This is useful for folks who want
to detect softlockups super early rather than wait and spend money on
cloud solutions with nothing but an eventual hung kernel. Although
this hadn't gone through linux-next it's also a stable fix, so we
might as well roll through the fixes now"

IPQ95xx SoCs have different OPPs available for the CPU based on
the SoC variant. This can be determined from an eFuse register
present in the silicon.
Added support for ipq95xx on nvmem driver which helps to
determine OPPs at runtime based on the eFuse register which
has the CPU frequency limits. opp-supported-hw dt binding
can be used to indicate the available OPPs for each limit.

nvmem driver also creates the "cpufreq-dt" platform_device after

cpufreq-dt handles the actual cpufreq implementation.

IPQ8074 comes in 3 families:
* IPQ8070A/IPQ8071A (Acorn) up to 1.4GHz
* IPQ8172/IPQ8173/IPQ8174 (Oak) up to 1.4GHz
* IPQ8072A/IPQ8074A/IPQ8076A/IPQ8078A (Hawkeye) up to 2.2GHz
So, in order to be able to share one OPP table lets add support for IPQ8074
family based of SMEM SoC ID-s as speedbin fuse is always 0 on IPQ8074.
IPQ8074 compatible is blacklisted from DT platdev as the cpufreq device
will get created by NVMEM CPUFreq driver.

Pull iommufd updates from Jason Gunthorpe:
"This brings three new iommufd capabilities:
- Dirty tracking for DMA.
AMD/ARM/Intel CPUs can now record if a DMA writes to a page in the
IOPTEs within the IO page table. This can be used to generate a
record of what memory is being dirtied by DMA activities during a
VM migration process. A VMM like qemu will combine the IOMMU dirty
bits with the CPU's dirty log to determine what memory to transfer.
VFIO already has a DMA dirty tracking framework that requires PCI
devices to implement tracking HW internally. The iommufd version
provides an alternative that the VMM can select, if available. The
two are designed to have very similar APIs.
- Userspace controlled attributes for hardware page tables
(HWPT/iommu_domain). There are currently a few generic attributes
for HWPTs (support dirty tracking, and parent of a nest). This is
an entry point for the userspace iommu driver to control the HW in
detail.
- Nested translation support for HWPTs. This is a 2D translation
scheme similar to the CPU where a DMA goes through a first stage to
determine an intermediate address which is then translated trough a
second stage to a physical address.
Like for CPU translation the first stage table would exist in VM
controlled memory and the second stage is in the kernel and matches
the VM's guest to physical map.
As every IOMMU has a unique set of parameter to describe the S1 IO
page table and its associated parameters the userspace IOMMU driver
has to marshal the information into the correct format.
This is 1/3 of the feature, it allows creating the nested
translation and binding it to VFIO devices, however the API to
support IOTLB and ATC invalidation of the stage 1 io page table,
and forwarding of IO faults are still in progress.
The series includes AMD and Intel support for dirty tracking. Intel
support for nested translation.
Along the way are a number of internal items:
- New iommu core items: ops->domain_alloc_user(),
ops->set_dirty_tracking, ops->read_and_clear_dirty(),
IOMMU_DOMAIN_NESTED, and iommu_copy_struct_from_user
- UAF fix in iopt_area_split()
- Spelling fixes and some test suite improvement"

drm: renesas: shmobile: Atomic conversion + DT support
Currently, there are two drivers for the LCD controller on Renesas
SuperH-based and ARM-based SH-Mobile and R-Mobile SoCs:
1. sh_mobile_lcdcfb, using the fbdev framework,
2. shmob_drm, using the DRM framework.
However, only the former driver is used, as all platform support
integrates the former. None of these drivers support DT-based systems.
Convert the SH-Mobile DRM driver to atomic modesetting, and add DT
support, complemented by the customary set of fixes and improvements.
