Currently, if hns3 PF or VF FLR reset failed after five times retry,
the reset done process will directly release the semaphore
which has already released in hclge_reset_prepare_general.
This will cause down operation fail.
So this patch fixes it by adding reset state judgement. The up operation is
only called after successful PF FLR reset.

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

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.

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.

The rpm_requests device nodes have the compatible node. As such the
rpmsg core uses OF modalias instead of a native rpmsg modalias. Thus if
smd-rpm is built as a module, it doesn't get autoloaded for the device.
Revert the commit bcabe1e091 ("soc: qcom: smd-rpm: Match rpmsg channel
instead of compatible")

Currently, scm driver only supports full dump when download
mode is selected. Add support to enable minidump as well as
enable it along with fulldump.

Currently on Qualcomm SoC, download_mode is enabled if
CONFIG_QCOM_SCM_DOWNLOAD_MODE_DEFAULT is selected or
passed a boolean value from command line.
Refactor the code such that it supports multiple download
modes and drop CONFIG_QCOM_SCM_DOWNLOAD_MODE_DEFAULT config
instead, give interface to set the download mode from
module parameter while being backword compatible at the
same time.

MSM8909, MSM8916 and MSM8939 all do not make use of pd-mapper, add them to
the list similar to the other older platforms to avoid the following
message in dmesg when booting:
"PDM: no support for the platform, userspace daemon might be required."

X1E80100 has the same protection domains as SM8550, except that MPSS is
missing. Add it to the in-kernel pd-mapper to avoid having to run the
daemon in userspace for charging and audio functionality.

qseecom_scm_dev(), qseecom_dma_alloc() and qseecom_dma_free() are no
longer used following the conversion to using tzmem. Remove them.

We currently only correctly convert the virtual address passed by the
caller to qcom_tzmem_to_phys() if it corresponds to the base address of
the chunk. If the user wants to convert some pointer at an offset
relative to that base address, we'll return 0. Let's change the
implementation of qcom_tzmem_to_phys(): iterate over the chunks and try
to call gen_pool_virt_to_phys() just-in-time instead of trying to call
it only once when creating the chunk.

Currently get_wq_ctx() is wrongly configured as a standard call. When two
SMC calls are in sleep and one SMC wakes up, it calls get_wq_ctx() to
resume the corresponding sleeping thread. But if get_wq_ctx() is
interrupted, goes to sleep and another SMC call is waiting to be allocated
a waitq context, it leads to a deadlock.
To avoid this get_wq_ctx() must be an atomic call and can't be a standard
SMC call. Hence mark get_wq_ctx() as a fast call.
