During the rework of the fan behavior control code in commit
d8e8362b09d3 ("platform/x86: acer-wmi: Fix setting of fan behavior"),
acer_toggle_turbo() was changed to use WMID_gaming_set_fan_behavior()
instead of WMID_gaming_set_u64() when switching the fans to turbo
mode. The new function however does not check if the necessary
capability (ACER_CAP_TURBO_FAN) is actually enabled on a given
machine, causing the driver to potentially access unsupported
features.
Fix this by manually checking if ACER_CAP_TURBO_FAN is enabled
on a given machine before changing the fan mode.

hp-bioscfg has a MODULE_DEVICE_TABLE with a GUID in it that looks
plausible, but the module doesn't automatically load on applicable
systems.
This is because the GUID has some lower case characters and so it
doesn't match the modalias during boot. Update the GUIDs to be all
uppercase.

The GET_INSTANCE_ID macro that caused a kernel panic when accessing sysfs
attributes:
1. Off-by-one error: The loop condition used '<=' instead of '<',
causing access beyond array bounds. Since array indices are 0-based
and go from 0 to instances_count-1, the loop should use '<'.
2. Missing NULL check: The code dereferenced attr_name_kobj->name
without checking if attr_name_kobj was NULL, causing a null pointer
dereference in min_length_show() and other attribute show functions.
The panic occurred when fwupd tried to read BIOS configuration attributes:
Oops: general protection fault [#1] SMP KASAN NOPTI
KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]
RIP: 0010:min_length_show+0xcf/0x1d0 [hp_bioscfg]
Add a NULL check for attr_name_kobj before dereferencing and corrects
the loop boundary to match the pattern used elsewhere in the driver.

Fix several issues in dw_dp_bind() error handling:
1. Missing return after drm_bridge_attach() failure - the function
continued execution instead of returning an error.
2. Resource leak: drm_dp_aux_register() is not a devm function, so
drm_dp_aux_unregister() must be called on all error paths after
aux registration succeeds. This affects errors from:
- drm_bridge_attach()
- phy_init()
- devm_add_action_or_reset()
- platform_get_irq()
- devm_request_threaded_irq()
3. Bug fix: platform_get_irq() returns the IRQ number or a negative
error code, but the error path was returning ERR_PTR(ret) instead
of ERR_PTR(dp->irq).
Use a goto label for cleanup to ensure consistent error handling.

The upper limit of the firmware queue fill state for each APQN
is reported by the hwinfo.qd field. This field shows the
numbers 0-7 for 1-8 queue spaces available. But the exploiting
code assumed the real boundary is stored there and thus stoppes
queuing in messages one tick too early.
Correct the limit calculation and thus offer a boost
of 12.5% performance for high traffic on one APQN.

Changing the caller to check pts.level == 0 avoids demanding a bit of

On 32-bit machines with CONFIG_ARM_LPAE, it is possible for lowmem
allocations to be backed by addresses physical memory above the 32-bit
address limit, as found while experimenting with larger VMSPLIT
configurations.
This caused the qemu virt model to crash in the GICv3 driver, which
allocates the 'itt' object using GFP_KERNEL. Since all memory below
the 4GB physical address limit is in ZONE_DMA in this configuration,
kmalloc() defaults to higher addresses for ZONE_NORMAL, and the
ITS driver stores the physical address in a 32-bit 'unsigned long'
variable.
Change the itt_addr variable to the correct phys_addr_t type instead,
along with all other variables in this driver that hold a physical
address.
The gicv5 driver correctly uses u64 variables, while all other irqchip
drivers don't call virt_to_phys or similar interfaces. It's expected that
other device drivers have similar issues, but fixing this one is
sufficient for booting a virtio based guest.

The cpu_bitmap flexible array now contains more than just the cpu_bitmap.
In preparation for changing the static mm_struct definitions to cover for
the additional space required, change the cpu_bitmap type from "unsigned
long" to "char", require an unsigned long alignment of the flexible array,
and rename the field from "cpu_bitmap" to "flexible_array".
Introduce the MM_STRUCT_FLEXIBLE_ARRAY_INIT macro to statically initialize
the flexible array. This covers the init_mm and efi_mm static
definitions.
This is a preparation step for fixing the missing mm_cid size for static
mm_struct definitions.

The RX flowid programming initializes the TCAM mask to all ones, but
then overwrites it when clearing the MAC DA mask bits. This results
in losing the intended initialization and may affect other match fields.
Update the code to clear the MAC DA bits using an AND operation, making
the handling of mask[0] consistent with mask[1], where the field-specific
bits are cleared after initializing the mask to ~0ULL.

Make the addrs_lock be per port, not per ipvlan dev.
Initial code seems to be written in the assumption,
that any address change must occur under RTNL.
But it is not so for the case of IPv6. So
1) Introduce per-port addrs_lock.
2) It was needed to fix places where it was forgotten
to take lock (ipvlan_open/ipvlan_close)
This appears to be a very minor problem though.
Since it's highly unlikely that ipvlan_add_addr() will
be called on 2 CPU simultaneously. But nevertheless,
this could cause:
1) False-negative of ipvlan_addr_busy(): one interface
iterated through all port->ipvlans + ipvlan->addrs
under some ipvlan spinlock, and another added IP
under its own lock. Though this is only possible
for IPv6, since looks like only ipvlan_addr6_event() can be
called without rtnl_lock.
2) Race since ipvlan_ht_addr_add(port) is called under
different ipvlan->addrs_lock locks
This should not affect performance, since add/remove IP
is a rare situation and spinlock is not taken on fast
paths.

copy_to_user() returns the number of bytes not copied, thus if there is
a problem a positive number. However the ioctl callback is supposed to
return a negative error code on error.
This error is a unfortunate as strictly speaking it became ABI with the
introduction of pwm character devices. However I never saw the issue in
real life -- I found this by code inspection -- and it only affects an
error case where readonly memory is passed to the ioctls or the address
mapping changes while the ioctl is active. Also there are already error
cases returning negative values, so the calling code must be prepared to
see such values already.

custom mtk_gem_obj structure and migrate drivers to use the API
defined drm_gem_dma_object structure instead, and to align all of
the functions to be similar to the logic from drm_gem_dma_helper.
Unfortunately, for this driver it wasn't possible to directly use
the drm_gem_dma_helper callbacks (apart from .print_info), as the
DMA mapping here is done on specific dma devices instead of the
main DRM device.
Also, since the mtk_gem_obj structure is no more, also migrate the
mtk_plane.c code to grab the DMA address from a drm_gem_dma_object
and replace the inclusion of the custom mtk_gem.h header (as it is
now unneeded) with the DRM API provided drm_gem_dma_helper.
While at it, also set DRM_GEM_DMA_HELPER as an unconditional
dependency (remove the `if DRM_FBDEV_EMULATION` from the select
DRM_GEM_DMA_HELPER statement in Kconfig).
This resolves an issue pointed by UBSAN, as when using drm_fbdev_dma
the drm_gem_object is supposed to be child of a drm_gem_dma_object
instead of a custom mtk_gem_obj (or the mtk_gem_obj should have been
reordered to have the same fields as drm_gem_dma_object, but that
would have been too fragile and generally a bad idea anyway).

Trying to find the next bridge and deferring probe in the bridge attach
callback is much too late. At this point the driver has already finished
probing and is now running the component bind code path. What's even
worse is that in the specific case of the DSI host being the last
component to be added as part of the dsi_host_attach callback, the code
path that this is in:
-> devm_drm_of_get_bridge()
mtk_dpi_bridge_attach()
drm_bridge_attach()
mtk_dpi_bind()
...
component_add()
mtk_dsi_host_attach()
anx7625_attach_dsi()
anx7625_link_bridge()
- done_probing callback for of_dp_aux_populate_bus()
of_dp_aux_populate_bus()
anx7625_i2c_probe()
_cannot_ return probe defer:

anx7625 4-0058: [drm:anx7625_i2c_probe] probe done
This results in the whole display driver failing to probe.
Perhaps this was an attempt to mirror the structure in the DSI driver;
but in the DSI driver the next bridge is retrieved in the DSI attach
callback, not the bridge attach callback.
Move the code finding the next bridge back to the probe function so that
deferred probing works correctly. Also rework the fallback to the old OF
graph endpoint numbering scheme so that deferred probing logs in both
cases.
This issue was found on an MT8183 Jacuzzi device with an extra patch
enabling the DPI-based external display pipeline. Also tested on an
MT8192 Hayato device with both DSI and DPI display pipelines enabled.

The timestamp WA does not work on a VF because it requires reading MMIO
registers, which are inaccessible on a VF. This timestamp WA confuses
LRC sampling on a VF during TDR, as the LRC timestamp would always read
as 1 for any active context. Disable the timestamp WA on VFs to avoid
this confusion.

ICU_TSSRk register as a countermeasure.
Currently, a spurious interrupt is generated on the resume path of s2idle

enabling/disabling of the TINT enable bit.
Fix this issue by not setting TSSR(TINT Source) and TITSR(TINT Detection

NFC packets may have NUL-bytes. Checking for string length is not a correct
assumption here. As long as there is a check for the length copied from
copy_from_user, all should be fine.
The fix only prevented the syzbot reproducer from triggering the bug
because the packet is not enqueued anymore and the code that triggers the
bug is not exercised.
The fix even broke

0 is a valid DMA address [1] so using it as the error value can lead to
errors. The error value of dma_map_XXX() functions is DMA_MAPPING_ERROR
which is ~0. The callers of otx2_dma_map_page() use dma_mapping_error()
to test the return value of otx2_dma_map_page(). This means that they
would not detect an error in otx2_dma_map_page().
Make otx2_dma_map_page() return the raw value of dma_map_page_attrs().
