[ Upstream commit 185cc2352c ]
In hidden SSID we have separate BSS entries for the beacon and for the
probe response(s).
The BSS entry time stamps represent the age of the BSS;
when was the last time we heard the BSS.
When we receive a beacon of a hidden SSID it means that we heard that
BSS, so it makes sense to indicate that in the probe response entries.
Do that.

The 88e1510 PHY has an erratum where the phy downshift counter is not
cleared after phy being suspended(BMCR_PDOWN set) and then later
resumed(BMCR_PDOWN cleared). This can cause the gigabit link to
intermittently downshift to a lower speed.
Disabling and re-enabling the downshift feature clears the counter,
allowing the PHY to retry gigabit link negotiation up to the programmed
retry count times before downshifting. This behavior has been observed
on copper links.

This does not work with controllers which have fixed size BARs that are
smaller than the requested BAR size. One such controller is Renesas R-Car
V4H PCIe controller, which has BAR4 size limited to 256 bytes, which is
much less than one of the BAR size, 131072 currently requested by this
test. A lot of controllers drivers in-tree have fixed size BARs, and they
do work perfectly fine, but it is only because their fixed size is larger
than the size requested by pci-epf-test.c
Adjust the test such that in case a fixed size BAR is detected, the fixed
BAR size is used, as that is the only possible option.
This helps with test failures reported as follows:
pci_epf_test pci_epf_test.0: requested BAR size is larger than fixed size
pci_epf_test pci_epf_test.0: Failed to allocate space for BAR4

As currently, idpf_vport_{start,stop}() is called from several flows
with inconsistent RTNL locking, we need to synchronize them to avoid
runtime assertions. Notably:
* idpf_{open,stop}() -- regular NDOs, RTNL is always taken;
* idpf_initiate_soft_reset() -- usually called under RTNL;
* idpf_init_task -- called from the init work, needs RTNL;
* idpf_vport_dealloc -- called without RTNL taken, needs it.
Expand common idpf_vport_{start,stop}() to take an additional bool
telling whether we need to manually take the RTNL lock.

Currently, misc_deregister() uses list_del() to remove the device
from the list. After list_del(), the list pointers are set to
LIST_POISON1 and LIST_POISON2, which may help catch use-after-free bugs,
but does not reset the list head.
If misc_deregister() is called more than once on the same device,
list_empty() will not return true, and list_del() may be called again,
leading to undefined behavior.
Replace list_del() with list_del_init() to reinitialize the list head
after deletion. This makes the code more robust against double
deregistration and allows safe usage of list_empty() on the miscdevice
after deregistration.
[ Note, this seems to keep broken out-of-tree drivers from doing foolish
things. While this does not matter for any in-kernel drivers,
external drivers could use a bit of help to show them they shouldn't
be doing stuff like re-registering misc devices - gregkh ]

Replace the UART driver-specific logic for clock selection with the GENI

In the __cdnsp_gadget_init() and cdnsp_gadget_exit() functions, the gadget
structure (pdev->gadget) was freed before its endpoints.
The endpoints are linked via the ep_list in the gadget structure.
Freeing the gadget first leaves dangling pointers in the endpoint list.
When the endpoints are subsequently freed, this results in a use-after-free.
Fix:
By separating the usb_del_gadget_udc() operation into distinct "del" and
"put" steps, cdnsp_gadget_free_endpoints() can be executed prior to the
final release of the gadget structure with usb_put_gadget().

[ Upstream commit 6f616757dd ]
The "usxgmii" phy-mode that the Felix switch ports support on LS1028A is
not quite USXGMII, it is defined by the USXGMII multiport specification
document as 10G-QXGMII. It uses the same signaling as USXGMII, but it
multiplexes 4 ports over the link, resulting in a maximum speed of 2.5G
per port.
This change is needed in preparation for the lynx-10g SerDes driver on
LS1028A, which will make a more clear distinction between usxgmii
(supported on lane 0) and 10g-qxgmii (supported on lane 1). These
protocols have their configuration in different PCCR registers (PCCRB vs
PCCR9).
Continue parsing and supporting single-port-per-lane USXGMII when found
in the device tree as usual (because it works), but add support for
10G-QXGMII too. Using phy-mode = "10g-qxgmii" will be required when
modifying the device trees to specify a "phys" phandle to the SerDes
lane. The result when the "phys" phandle is present but the phy-mode is
wrong is undefined.
The only PHY driver in known use with this phy-mode, AQR412C, will gain
logic to transition from "usxgmii" to "10g-qxgmii" in a future change.
Prepare the driver by also setting PHY_INTERFACE_MODE_10G_QXGMII in
supported_interfaces when PHY_INTERFACE_MODE_USXGMII is there, to
prevent breakage with existing device trees.

[ Upstream commit 8c0b9ed240 ]
devmem test fails on NIPA. Most likely we get skb(s) with readable
frags (why?) but the failure manifests as an OOM. The OOM happens
because ncdevmem spams the following message:
recvmsg ret=-1
recvmsg: Bad address
As of today, ncdevmem can't deal with various reasons of EFAULT:
- falling back to regular recvmsg for non-devmem skbs
- increasing ctrl_data size (can't happen with ncdevmem's large buffer)
Exit (cleanly) with error when recvmsg returns EFAULT. This should at
least cause the test to cleanup its state.

[ Upstream commit 68f3c044f3 ]
[Why]
There is a `scale` sysfs attribute that can be used to indicate when
non-linear brightness scaling is in use. As Custom brightness curves
work by linear interpolation of points the scale is no longer linear.
[How]
Indicate non-linear scaling when custom brightness curves in use and
linear scaling otherwise.

[ Upstream commit 12cdfb61b3 ]
[Why]
dm_mst_get_pbn_divider() returns value integer coming from
the cast from fixed point, but the casted integer will then be used
in dfixed_const to be multiplied by 4096. The cast from fixed point to integer
causes the calculation error becomes bigger when multiplied by 4096.
That makes the calculated pbn_div value becomes smaller than
it should be, which leads to the req_slot number becomes bigger.
Such error is getting reflected in 8k30 timing,
where the correct and incorrect calculated req_slot 62.9 Vs 63.1.
That makes the wrong calculation failed to light up 8k30
after a dock under HBR3 x 4.
[How]
Restore the accuracy by keeping the fraction part
calculated for the left shift operation.
