isofs: Convert rock_ridge_symlink_read_folio to use a folio
Remove the conversion back into a page and use the folio APIs throughout.
Remove the setting of PG_error instead of converting it; it is unused
by core code or by the rest of isofs, so it serves no purpose here.
Use folio_end_read() to save an atomic operation and unify the two
exit paths.

985cfe501b thunderbolt: debugfs: Fix margin debugfs node creation condition
The margin debugfs node controls the "Enable Margin Test" field of the
lane margining operations. This field selects between either low or high
voltage margin values for voltage margin test or left or right timing
margin values for timing margin test.

According to the USB4 specification, whether or not the "Enable Margin
Test" control applies, depends on the values of the "Independent
High/Low Voltage Margin" or "Independent Left/Right Timing Margin"
capability fields for voltage and timing margin tests respectively. The
pre-existing condition enabled the debugfs node also in the case where
both low/high or left/right margins are returned, which is incorrect.
This change only enables the debugfs node in question, if the specific
required capability values are met.

e0eec24e2e memblock: make memblock_set_node() also warn about use of MAX_NUMNODES
On an (old) x86 system with SRAT just covering space above 4Gb:

    ACPI: SRAT: Node 0 PXM 0 [mem 0x100000000-0xfffffffff] hotplug

the commit referenced below leads to this NUMA configuration no longer
being refused by a CONFIG_NUMA=y kernel (previously

    NUMA: nodes only cover 6144MB of your 8185MB e820 RAM. Not used.
    No NUMA configuration found
    Faking a node at [mem 0x0000000000000000-0x000000027fffffff]

was seen in the log directly after the message quoted above), because of
memblock_validate_numa_coverage() checking for NUMA_NO_NODE (only). This
in turn led to memblock_alloc_range_nid()'s warning about MAX_NUMNODES
triggering, followed by a NULL deref in memmap_init() when trying to
access node 64's (NODE_SHIFT=6) node data.

To compensate said change, make memblock_set_node() warn on and adjust
a passed in value of MAX_NUMNODES, just like various other functions
already do.

785778ce21 drm/i915/display: add platform descriptors
We'll need to start identifying the platforms independently in display
code in order to break free from the i915 and xe IS_<PLATFORM>()
macros. This is fairly straightforward, as we already identify most
platforms by PCI ID in display probe anyway.

As the first step, add platform descriptors with pointers to display
info. We'll have more platforms than display info, so minimize
duplication:

- Add separate skl/kbl/cfl/cml descriptors while they share the display
  info.

- Add separate jsl/ehl descriptors while they share the display info.

Identify ADL-P (and derivatives) and DG2 descriptors by their names even
though their display info is Xe LPD or HPD.

now also done for GMD ID based platforms. However, without matches, the
end result is the same.

c66f3b40b1 RISC-V: KVM: Fix incorrect reg_subtype labels in kvm_riscv_vcpu_set_reg_isa_ext function
In the function kvm_riscv_vcpu_set_reg_isa_ext, the original code
used incorrect reg_subtype labels KVM_REG_RISCV_SBI_MULTI_EN/DIS.
These have been corrected to KVM_REG_RISCV_ISA_MULTI_EN/DIS respectively.
Although they are numerically equivalent, the actual processing
will not result in errors, but it may lead to ambiguous code semantics.

2d707b4e37 RISC-V: KVM: No need to use mask when hart-index-bit is 0
When the maximum hart number within groups is 1, hart-index-bit is set to
0. Consequently, there is no need to restore the hart ID from IMSIC
addresses and hart-index-bit settings. Currently, QEMU and kvmtool do not
pass correct hart-index-bit values when the maximum hart number is a
power of 2, thereby avoiding this issue. Corresponding patches for QEMU
and kvmtool will also be dispatched.
