commit 2d1684a077 upstream.
Currently this is hidden behind perfmon_capable() since this is
technically an info leak, given that this is a system wide metric.
However the granularity reported here is always PAGE_SIZE aligned, which
matches what the core kernel is already willing to expose to userspace
if querying how many free RAM pages there are on the system, and that
doesn't need any special privileges. In addition other drm drivers seem
happy to expose this.
The motivation here if with oneAPI where they want to use the system
wide 'used' reporting here, so not the per-client fdinfo stats. This has
also come up with some perf overlay applications wanting this
information.

We don't use OF ports and remote-endpoints to connect the CSI2RX bridge
and this device in the device tree, thus it is wrong to use
v4l2_create_fwnode_links_to_pad() to create the media graph link between
the two.
It works out on accident, as neither the source nor the sink implement
the .get_fwnode_pad() callback, and the framework helper falls back on
using the first source and sink pads to create the link between them.
Instead, manually create the media link from the first source pad of the
bridge to the first sink pad of the J721E CSI2RX.

commit 4bd8a61476 upstream.
The vivid driver supports the <Vendor Command With ID> message,
but if the Vendor ID of the received message didn't match the Vendor ID
of the CEC Adapter, then it ignores it (good) and returns 0 (bad).
It should return -ENOMSG to indicate that other followers should be
asked to handle it. Return code 0 means that the driver handled it,
which is wrong in this case.
As a result, userspace followers never get the chance to process such a
message.
Refactor the code a bit to have the function return -ENOMSG at the end,
drop the default case, and ensure that the message handlers return 0.
That way 0 is only returned if the message is actually handled in the
vivid_received() function.

VIRQs come in 3 flavors, per-VPU, per-domain, and global, and the VIRQs
are tracked in per-cpu virq_to_irq arrays.
Per-domain and global VIRQs must be bound on CPU 0, and
bind_virq_to_irq() sets the per_cpu virq_to_irq at registration time
Later, the interrupt can migrate, and info->cpu is updated. When
calling __unbind_from_irq(), the per-cpu virq_to_irq is cleared for a
different cpu. If bind_virq_to_irq() is called again with CPU 0, the
stale irq is returned. There won't be any irq_info for the irq, so
things break.
Make xen_rebind_evtchn_to_cpu() update the per_cpu virq_to_irq mappings
to keep them update to date with the current cpu. This ensures the
correct virq_to_irq is cleared in __unbind_from_irq().

Change find_virq() to return -EEXIST when a VIRQ is bound to a

from bind_virq_to_irq() to propogate the error upwards.
Some VIRQs are per-cpu, but others are per-domain or global. Those must
be bound to CPU0 and can then migrate elsewhere. The lookup for
per-domain and global will probably fail when migrated off CPU 0,
especially when the current CPU is tracked. This now returns -EEXIST
instead of BUG_ON().
A second call to bind a per-domain or global VIRQ is not expected, but
make it non-fatal to avoid trying to look up the irq, since we don't
know which per_cpu(virq_to_irq) it will be in.

When Xen began using the device power management API in May 2008 with

There is an issue possible where TI AM33xx SoCs do not boot properly after
a reset if EMU0/EMU1 pins were used as GPIO and have been driving low level
actively prior to reset [1].
"Advisory 1.0.36 EMU0 and EMU1: Terminals Must be Pulled High Before
ICEPick Samples
The state of the EMU[1:0] terminals are latched during reset to determine
ICEPick boot mode. For normal device operation, these terminals must be
pulled up to a valid high logic level ( > VIH min) before ICEPick samples
the state of these terminals, which occurs
[five CLK_M_OSC clock cycles - 10 ns] after the falling edge of WARMRSTn.
Many applications may not require the secondary GPIO function of the
EMU[1:0] terminals. In this case, they would only be connected to pull-up
resistors, which ensures they are always high when ICEPick samples.
However, some applications may need to use these terminals as GPIO where
they could be driven low before reset is asserted. This usage of the
EMU[1:0] terminals may require special attention to ensure the terminals
are allowed to return to a valid high-logic level before ICEPick samples
the state of these terminals.
When any device reset is asserted, the pin mux mode of EMU[1:0] terminals
configured to operate as GPIO (mode 7) will change back to EMU input
(mode 0) on the falling edge of WARMRSTn. This only provides a short period
of time for the terminals to return high if driven low before reset is
asserted...
If the EMU[1:0] terminals are configured to operate as GPIO, the product
should be designed such these terminals can be pulled to a valid high-logic
level within 190 ns after the falling edge of WARMRSTn."
We've noticed this problem with custom am335x hardware in combination with
recently implemented cold reset method
(commit 6521f6a195 ("ARM: AM33xx: PRM: Implement REBOOT_COLD")).
It looks like the problem can affect other HW, for instance AM335x
Chiliboard, because the latter has LEDs on GPIO3_7/GPIO3_8 as well.
One option would be to check if the pins are in GPIO mode and either switch
to output active high, or switch to input and poll until the external
pull-ups have brought the pins to the desired high state. But fighting
with GPIO driver for these pins is probably not the most straight forward
approch in a reboot handler.
Fortunately we can easily control pinmuxing here and rely on the external
pull-ups. TI recommends 4k7 external pull up resistors [2] and even with
quite conservative estimation for pin capacity (1 uF should never happen)
the required delay shall not exceed 5ms.

MAIN_PADCFG_CTRL_MMR_CFG0_PADCONFIG0 with address 0x000f4000 and ends
with the MAIN_PADCFG_CTRL_MMR_CFG0_PADCONFIG150 register with address
0x000f4258, as a result of which, total size of the region is 0x25c
instead of 0x2ac.

pm8010 is a camera specific PMIC, and may not be present on some
devices. These may instead use a dedicated vreg for this purpose (Dell
XPS 9345, Dell Inspiron..) or use USB webcam instead of a MIPI one
alltogether (Lenovo Thinbook 16, Lenovo Yoga..).
Disable pm8010 by default, let platforms that actually have one onboard
enable it instead.

commit 316294bb66 upstream.
Reading the hardware registers of the &slimbam on RB3 reveals that the BAM
supports only 23 pipes (channels) and supports 4 EEs instead of 2. This
hasn't caused problems so far since nothing is using the extra channels,
but attempting to use them would lead to crashes.
The bam_dma driver might warn in the future if the num-channels in the DT
are wrong, so correct the properties in the DT to avoid future regressions.

commit f73c82c855 upstream.
On most MSM8939 devices, the bootloader already initializes the display to
show the boot splash screen. In this situation, MDSS is already configured
and left running when starting Linux. To avoid side effects from the
bootloader configuration, the MDSS reset can be specified in the device
tree to start again with a clean hardware state.
The reset for MDSS is currently missing in msm8939.dtsi, which causes
errors when the MDSS driver tries to re-initialize the registers:
dsi_err_worker: status=6
dsi_err_worker: status=6
dsi_err_worker: status=6
...
It turns out that we have always indirectly worked around this by building
the MDSS driver as a module. Before v6.17, the power domain was temporarily
turned off until the module was loaded, long enough to clear the register
contents. In v6.17, power domains are not turned off during boot until
sync_state() happens, so this is no longer working. Even before v6.17 this
resulted in broken behavior, but notably only when the MDSS driver was
built-in instead of a module.

commit 496f9372ea upstream.
In the ACPI debugger interface, the helper functions for read and write
operations use "int" as the length parameter data type. When a large
"size_t count" is passed from the file operations, this cast to "int"
results in truncation and a negative value due to signed integer
representation.
Logically, this negative number propagates to the min() calculation,
where it is selected over the positive buffer space value, leading to
unexpected behavior. Subsequently, when this negative value is used in
copy_to_user() or copy_from_user(), it is interpreted as a large positive
value due to the unsigned nature of the size parameter in these functions,
causing the copy operations to attempt handling sizes far beyond the
intended buffer limits.
Address the issue by:
- Changing the length parameters in acpi_aml_read_user() and
acpi_aml_write_user() from "int" to "size_t", aligning with the
expected unsigned size semantics.
- Updating return types and local variables in acpi_aml_read() and
acpi_aml_write() to "ssize_t" for consistency with kernel file
operation conventions.
- Using "size_t" for the "n" variable to ensure calculations remain
unsigned.
- Using min_t() for circ_count_to_end() and circ_space_to_end() to
ensure type-safe comparisons and prevent integer overflow.

commit d0759b1098 upstream.
The ACPI handle passed to acpi_extract_properties() as the first
argument represents the ACPI namespace scope in which to look for
objects returning buffers associated with buffer properties.
For _DSD objects located immediately under ACPI devices, this handle is
the same as the handle of the device object holding the _DSD, but for
data-only subnodes it is not so.
First of all, data-only subnodes are represented by objects that
cannot hold other objects in their scopes (like control methods).
Therefore a data-only subnode handle cannot be used for completing
relative pathname segments, so the current code in
in acpi_nondev_subnode_extract() passing a data-only subnode handle
to acpi_extract_properties() is invalid.
Moreover, a data-only subnode of device A may be represented by an
object located in the scope of device B (which kind of makes sense,
for instance, if A is a B's child). In that case, the scope in
question would be the one of device B. In other words, the scope
mentioned above is the same as the scope used for subnode object
lookup in acpi_nondev_subnode_extract().
Accordingly, rearrange that function to use the same scope for the
extraction of properties and subnode object lookup.

In the upcoming changes, the ELF_DETAILS macro will be extended with
the ".modinfo" section, which will cause an error:
>> s390x-linux-ld: .tmp_vmlinux1: warning: allocated section `.modinfo' not in segment
>> s390x-linux-ld: .tmp_vmlinux2: warning: allocated section `.modinfo' not in segment
>> s390x-linux-ld: vmlinux.unstripped: warning: allocated section `.modinfo' not in segment
This happens because the .vmlinux.info use :NONE to override the default
segment and tell the linker to not put the section in any segment at all.
To avoid this, we need to change the sections order that will be placed
in the default segment.

[ Upstream commit 4f375ade6a ]
When unpinning a BPF hash table (htab or htab_lru) that contains internal
structures (timer, workqueue, or task_work) in its values, a BUG warning
is triggered:
BUG: sleeping function called from invalid context at kernel/bpf/hashtab.c:244
in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 14, name: ksoftirqd/0
...
The issue arises from the interaction between BPF object unpinning and
RCU callback mechanisms:
1. BPF object unpinning uses ->free_inode() which schedules cleanup via
call_rcu(), deferring the actual freeing to an RCU callback that
executes within the RCU_SOFTIRQ context.
2. During cleanup of hash tables containing internal structures,
htab_map_free_internal_structs() is invoked, which includes
cond_resched() or cond_resched_rcu() calls to yield the CPU during
potentially long operations.
However, cond_resched() or cond_resched_rcu() cannot be safely called from
atomic RCU softirq context, leading to the BUG warning when attempting
to reschedule.
Fix this by changing from ->free_inode() to ->destroy_inode() and rename
bpf_free_inode() to bpf_destroy_inode() for BPF objects (prog, map, link).
This allows direct inode freeing without RCU callback scheduling,
avoiding the invalid context warning.
