rt_mutex_handle_deadlock() is called with rt_mutex::wait_lock held. In the
good case it returns with the lock held and in the deadlock case it emits a
warning and goes into an endless scheduling loop with the lock held, which
triggers the 'scheduling in atomic' warning.
Unlock rt_mutex::wait_lock in the dead lock case before issuing the warning
and dropping into the schedule for ever loop.

When the target context passed to enter_vmid_context() matches the
current running context, the function returns early without manipulating
the registers of the stage-2 MMU. This can result in a stale VMID due to
the lack of an ISB instruction in exit_vmid_context() after writing the
VTTBR when ARM64_WORKAROUND_SPECULATIVE_AT is not enabled.
For example, with pKVM enabled:
// Initially running in host context
enter_vmid_context(guest);
-> __load_stage2(guest); isb // Writes VTCR & VTTBR
exit_vmid_context(guest);
-> __load_stage2(host); // Restores VTCR & VTTBR
enter_vmid_context(host);
-> Returns early as we're already in host context
tlbi vmalls12e1is // !!! Can use the stale VMID as we
// haven't performed context
// synchronisation since restoring
// VTTBR.VMID
Add an unconditional ISB instruction to exit_vmid_context() after
restoring the VTTBR. This already existed for the
ARM64_WORKAROUND_SPECULATIVE_AT path, so we can simply hoist that onto
the common path.

When initialising the nVHE hypervisor, we invalidate potentially stale

However, this invalidation operation applies only to the active VMID

Allow boot instances to use memory reserved by the reserve_mem boot
option.
reserve_mem=12M:4096:trace trace_instance=boot_mapped@trace
The above will allocate 12 megs with 4096 alignment and label it "trace".
The second parameter will create a "boot_mapped" instance and use the
memory reserved and labeled as "trace" as the memory for the ring buffer.
That will create an instance called "boot_mapped":
/sys/kernel/tracing/instances/boot_mapped
Note, because the ring buffer is using a defined memory ranged, it will
act just like a memory mapped ring buffer. It will not have a snapshot
buffer, as it can't swap out the buffer. The snapshot files as well as any
tracers that uses a snapshot will not be present in the boot_mapped
instance.
Also note that reserve_mem is not reliable in acquiring the same physical
memory at each soft reboot. It is possible that KALSR could map the kernel
at the previous boot memory location forcing the reserve_mem to return a
different memory location. In this case, the previous ring buffer will be
lost.

In reset process, the driver will DOWN the port and then UINIT, in this
case, the setup tc process will UP the port before UINIT, so cause the
problem. Adds a DOWN process in UINIT to fix it.

When deleting netns, it is possible to still have some tasks running,
e.g. background tasks like tcpdump running in the background, not
stopped because the test has been interrupted.
Before deleting the netns, it is then safer to kill all attached PIDs,
if any. That should reduce some noises after the end of some tests, and
help with the debugging of some issues. That's why this modification is
seen as a "fix".

Fix an issue where `devm_regulator_register()` would fail for PSE
controllers that do not support current limit control, such as simple
GPIO-based controllers like the podl-pse-regulator. The
`REGULATOR_CHANGE_CURRENT` flag and `max_uA` constraint are now
conditionally set only if the `pi_set_current_limit` operation is
supported. This change prevents the regulator registration routine from
attempting to call `pse_pi_set_current_limit()`, which would return
`-EOPNOTSUPP` and cause the registration to fail.

The current power on opertation takes ISO state as power on finished
flag, but it is wrong. Before powering on operation really finishes,
powering off comes and powering off will never finish because the last
powering on still not finishes, so the following powering off actually
not trigger hardware state machine to run. SSAR is the last step when
powering on a domain, so need to wait SSAR done when powering on.

Commit 94833addfa ("net: thunderx: Unembed netdev structure") had
a go at dynamically allocating the netdev structures for the thunderx_bgx
driver. This change results in my ThunderX box catching fire (to be fair,
it is what it does best).
The issues with this change are that:
- bgx_lmac_enable() is called *after* bgx_acpi_register_phy() and
bgx_init_of_phy(), both expecting netdev to be a valid pointer.
- bgx_init_of_phy() populates the MAC addresses for *all* LMACs
attached to a given BGX instance, and thus needs netdev for each of
them to have been allocated.
There is a few things to be said about how the driver mixes LMAC and
BGX states which leads to this sorry state, but that's beside the point.
To address this, go back to a situation where all netdev structures
are allocated before the driver starts relying on them, and move the
freeing of these structures to driver removal. Someone brave enough
can always go and restructure the driver if they want.

The mpll_cfg, cur_ctr and phy_config members in struct dw_hdmi_plat_data
are only used to configure the Synopsys PHYs supported internally by DW
HDMI transmitter driver (gpu/drm/bridge/synopsys/dw-hdmi.c), via
hdmi_phy_configure_dwc_hdmi_3d_tx(), which is further invoked from
dw_hdmi_phy_init(). This is part of the internal
dw_hdmi_synopsys_phy_ops struct, managed within dw_hdmi_detect_phy().
To handle vendor PHYs, DW HDMI driver doesn't make use of the internal
PHY ops and, instead, relies on the glue layer to provide the phy_ops
and phy_name members of struct dw_hdmi_plat_data.
Drop the unnecessary assignments of DW internal PHY related members from
structs rk3228_hdmi_drv_data and rk3328_hdmi_drv_data, since both set
the phy_force_vendor flag and correctly provide the expected vendor PHY
data.

The RK3066 VOP sets a dma_stop bit when it's done scanning out a frame
and needs the driver to acknowledge that by clearing the bit.
Unless we clear it "between" frames, the RGB output only shows noise
instead of the picture. atomic_flush is the place for it that least
affects other code (doing it on vblank would require converting all
other usages of the reg_lock to spin_(un)lock_irq, which would affect
performance for everyone).
This seems to be a redundant synchronization mechanism that was removed
in later iterations of the VOP hardware block.

After a vsock socket has been added to a BPF sockmap, its prot->recvmsg
has been replaced with vsock_bpf_recvmsg(). Thus the following
recursiion could happen:
vsock_bpf_recvmsg()
-> __vsock_recvmsg()
-> vsock_connectible_recvmsg()
-> prot->recvmsg()
-> vsock_bpf_recvmsg() again
We need to fix it by calling the original ->recvmsg() without any BPF
sockmap logic in __vsock_recvmsg().

Currently, kasan_init_sw_tags() is called before setup_per_cpu_areas(),
so per_cpu(prng_state, cpu) accesses the same address regardless of the
value of "cpu", and the same seed value gets copied to the percpu area
for every CPU. Fix this by moving the call to smp_prepare_boot_cpu(),
which is the first architecture hook after setup_per_cpu_areas().

UAPI: net/sched - cxgb4: Fix -Wflex-array-member-not-at-end warning
Small patch series aimed at fixing a -Wflex-array-member-not-at-end
warning by creating a new tagged struct within a flexible structure.
We then use this new struct type to fix a problematic middle-flex-array
declaration in a composite struct.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
Change the type of the middle struct member currently causing
trouble from `struct tc_u32_sel` to `struct tc_u32_sel_hdr`.
Fix the following warning:
drivers/net/ethernet/chelsio/cxgb4/cxgb4_tc_u32_parse.h:245:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]

Use the `__struct_group()` helper to create a new tagged
`struct tc_u32_sel_hdr`. This structure groups together all the
members of the flexible `struct tc_u32_sel` except the flexible
array. As a result, the array is effectively separated from the
rest of the members without modifying the memory layout of the
flexible structure.
This new tagged struct will be used to fix problematic declarations
of middle-flex-arrays in composite structs[1].

Although it seems unlikely in practice - there would need to be
rx ring indexes greater than 10^10 - it is theoretically possible
for the filename of per rx ring debugfs files to be truncated.
This is because although a 16 byte buffer is provided, the length
of the filename is restricted to 10 bytes. Remove this restriction
and allow the entire buffer to be used.
Also reduce the buffer to 12 bytes, which is sufficient.
Given that the range of rx ring indexes likely much smaller than the
maximum range of a 32-bit signed integer, a smaller buffer could be
used, with some further changes. But this change seems simple, robust,
and has minimal stack overhead.

This corrects an out-by-one error in the maximum length of the package
version string. The size argument of snprintf includes space for the
trailing '\0' byte, so there is no need to allow extra space for it by
reducing the value of the size argument by 1.
Found by inspection.
