Pull EDAC fixes from Borislav Petkov:
- In Versalnet, handle the reporting of non-standard hw errors whose
information can come in more than one remote processor message.
- Explicitly reenable ECC checking after a warm reset in Altera OCRAM
as those registers are reset to default otherwise
- Fix single-bit error injection in Altera EDAC to not inject errors
directly in ECC RAM and thus lead to false double-bit errors due to
same ECC RAM being in concurrent use

The generation field of topology map is updated after initialized by zero.
The updated value of generation field is always zero, and is against
specification.
This commit fixes the bug.

The irq_domain_free_irqs() helper requires that the irq_domain_ops->free
callback is implemented. Otherwise, the kernel reports the warning message
"NULL pointer, cannot free irq" when irq_dispose_mapping() is invoked to
release the per-HART local interrupts.
Set irq_domain_ops->free to irq_domain_free_irqs_top() to cure that.

The purpose of commit 703eec1b2422 ("virtio_net: fixing XDP for fully
checksummed packets handling") is to record the flags in advance, as
their value may be overwritten in the XDP case. However, the flags
recorded under big mode are incorrect, because in big mode, the passed
buf does not point to the rx buffer, but rather to the page of the
submitted buffer. This commit fixes this issue.
For the small mode, the commit c11a49d58ad2 ("virtio_net: Fix mismatched
buf address when unmapping for small packets") fixed it.

Existing quirks to disable ASPM L0s and L1 use pci_disable_link_state(),
which disables ASPM states and prevents their use in the future. But since
they are FINAL quirks, they happen after ASPM has already been enabled.
Here's a typical call path:
pci_host_probe
pci_scan_root_bus_bridge
pci_scan_child_bus
pci_scan_slot
pci_scan_single_device
pci_device_add
pci_fixup_device(pci_fixup_header) # HEADER quirks
pcie_aspm_init_link_state
pcie_config_aspm_path
pcie_config_aspm_link
pcie_config_aspm_dev # ASPM may be enabled
pci_bus_add_devices
pci_bus_add_devices
pci_fixup_device(pci_fixup_final) # FINAL quirks
quirk_disable_aspm_l0s
pci_disable_link_state(dev, PCIE_LINK_STATE_L0S)
Sometimes enabling ASPM can make the link non-functional, so if we know
ASPM is broken on a device, we shouldn't enable it at all, even
temporarily.
Convert the existing quirks to use pcie_aspm_remove_cap() instead, which
overrides the ASPM Support advertised in PCIe Link Capabilities, and make
them HEADER quirks so they run before pcie_aspm_init_link_state() has a
chance to enable ASPM.

Possible unsafe locking scenario:

rlock((node_chain).rwsem);
lock(mem_hotplug_lock);

The lock ordering can cause potential deadlock. There are instances
where hmem_resource_lock is taken after (node_chain).rwsem, and vice
versa.
Split out the target update section of hmat_register_target() so that
hmat_callback() only envokes that section instead of attempt to register
hmem devices that it does not need to.

The original implement will re-init the EC when it reports a zero
value, and it's a workaround for the black box buggy firmware.
Now a contributer test and report that, the bug is that, the firmware
won't initialize the EC on boot, so the EC ramains in unusable status.
And it won't need to re-init it during runtime. The original implement
is not perfect, any write command will be ignored until we first read
it. Just re-init it unconditionally when the driver load could work.

Building gpd-fan driver without CONFIG_ACPI results in the following

The definitions for inb() and outb() come from <linux/io.h>
(specifically through <asm/io.h>), which is implicitly included via
<acpi_io.h>. When CONFIG_ACPI is not set, <acpi_io.h> is not included
resulting in <linux/io.h> to be omitted as well.
Since the driver does not depend on ACPI, remove <linux/acpi.h> and add
<linux/io.h> directly to fix the compilation errors.

Commit ac4e04d9e378 ("cpufreq: intel_pstate: Unchecked MSR aceess in
legacy mode") introduced a check for feature X86_FEATURE_IDA to verify
turbo mode support. Although this is the correct way to check for turbo
mode support, it causes issues on some platforms that disable turbo
during OS boot, but enable it later [1]. Before adding this feature
check, users were able to get turbo mode frequencies by writing 0 to
/sys/devices/system/cpu/intel_pstate/no_turbo post-boot.
To restore the old behavior on the affected systems while still
addressing the unchecked MSR issue on some Skylake-X systems, check
X86_FEATURE_IDA only immediately before updates of MSR_IA32_PERF_CTL
that may involve setting the Turbo Engage Bit (bit 32).

One of the factors of a link's grade is the channel load, which is
calculated from the AP's bss load element.
The current code takes this element from the beacon for an active link,
and from bss->ies for an inactive link.
bss->ies is set to either the beacon's ies or to the probe response
ones, with preference to the probe response (meaning that if there was
even one probe response, the ies of it will be stored in bss->ies and
won't be overiden by the beacon ies).
The probe response can be very old, i.e. from the connection time,
where a beacon is updated before each link selection (which is
triggered only after a passive scan).
In such case, the bss load element in the probe response will not
include the channel load caused by the STA, where the beacon will.
This will cause the inactive link to always have a lower channel
load, and therefore an higher grade than the active link's one.
This causes repeated link switches, causing the throughput to drop.
Fix this by always taking the ies from the beacon, as those are for
sure new.

During the development of the rate changes, I evidently made
some changes that shouldn't have been there; beacon templates
with rate_n_flags are only in old versions, so no changes to
them should have been necessary, and evidently broke on some

it would seem. Restore the old handling of this.

The list_for_each_entry() iterator must not be used outside the loop.
Even though we break and check for NULL, doing so still violates kernel
iteration rules and triggers Coccinelle's use_after_iter.cocci warning.
Cache the matched entry in aux_roc_te and use it consistently after the
loop. This follows iterator best practices, resolves the warning, and
makes the code more maintainable.

Fix the following corner case:-
Consider a 2M huge page SVM allocation, followed by prefetch call for
the first 4K page. The whole range is initially mapped with single PTE.
After the prefetch, this range gets split to first page + rest of the
pages. Currently, the first page mapping is not updated on MI300A (APU)
since page hasn't migrated. However, after range split PTE mapping it not
valid.
Fix this by forcing page table update for the whole range when prefetch
is called. Calling prefetch on APU doesn't improve performance. If all
it deteriotes. However, functionality has to be supported.
v2: Use apu_prefer_gtt as this issue doesn't apply to APUs with carveout
VRAM
v3: Simplify by setting the flag for all ASICs as it doesn't affect dGPU
v4: Remove v2 and v3 changes. Force update_mapping when range is split
at a size that is not aligned to prange granularity

When the BO pointer provided to amdgpu_bo_create_kernel() points to
non-NULL, amdgpu_bo_create_kernel() takes it as a hint to pin that address
rather than allocate a new BO.
This functionality is never desired for allocating ISP buffers. A new BO
should always be created when isp_kernel_buffer_alloc() is called, per the
description for isp_kernel_buffer_alloc().
Ensure this by zeroing *bo right before the amdgpu_bo_create_kernel() call.

[Why]
When changing resolution (e.g., 4K → FHD) in mirror/clone mode with
certain monitors, the monitor blanks and loses connection due to an early
exit in vrr_settings_require_update(). The function only checks if VRR
state, fixed refresh target, or min/max refresh rate range has changed.
During mode changes, if the calculated min/max refresh values remain the
same even though the stream's v_total changed, the function returns early
without updating vrr_params.adjust.v_total_min/max, leaving the monitor's
VRR timing parameters unsynced with the new mode, causing it to blank out.
[How]
Explicitly adjust VRR parameters to the stream's nominal v_total when VRR
is supported, but inactive.

Fix a potential deadlock caused by inconsistent spinlock usage
between interrupt and process contexts in the userq fence driver.
The issue occurs when amdgpu_userq_fence_driver_process() is called
from both:
- Interrupt context: gfx_v11_0_eop_irq() -> amdgpu_userq_fence_driver_process()
- Process context: amdgpu_eviction_fence_suspend_worker() ->
amdgpu_userq_fence_driver_force_completion() -> amdgpu_userq_fence_driver_process()
In interrupt context, the spinlock was acquired without disabling
interrupts, leaving it in {IN-HARDIRQ-W} state. When the same lock
is acquired in process context, the kernel detects inconsistent
locking since the process context acquisition would enable interrupts
while holding a lock previously acquired in interrupt context.
Kernel log shows:
[ 4039.310790] inconsistent {IN-HARDIRQ-W} -> {HARDIRQ-ON-W} usage.

Certain multi-GPU configurations (especially GFX12) may hit
data corruption when a DCC-compressed VRAM surface is shared across GPUs
using peer-to-peer (P2P) DMA transfers.
Such surfaces rely on device-local metadata and cannot be safely accessed
through a remote GPU’s page tables. Attempting to import a DCC-enabled
surface through P2P leads to incorrect rendering or GPU faults.
This change disables P2P for DCC-enabled VRAM buffers that are contiguous
and allocated on GFX12+ hardware. In these cases, the importer falls back
to the standard system-memory path, avoiding invalid access to compressed
surfaces.
Future work could consider optional migration (VRAM→System→VRAM) if a
performance regression is observed when `attach->peer2peer = false`.
Tested on:
- Dual RX 9700 XT (Navi4x) setup
- GNOME and Wayland compositor scenarios
- Confirmed no corruption after disabling P2P under these conditions
