Toke Høiland-Jørgensen 90fabae8a2 sch_cake: Return __NET_XMIT_STOLEN when consuming enqueued skb
When the GSO splitting feature of sch_cake is enabled, GSO superpackets
will be broken up and the resulting segments enqueued in place of the
original skb. In this case, CAKE calls consume_skb() on the original skb,
but still returns NET_XMIT_SUCCESS. This can confuse parent qdiscs into
assuming the original skb still exists, when it really has been freed. Fix
this by adding the __NET_XMIT_STOLEN flag to the return value in this case.

Cong Wang 8fc29ff391 kcm: fix strp_init() order and cleanup
strp_init() is called just a few lines above this csk->sk_user_data
check, it also initializes strp->work etc., therefore, it is
unnecessary to call strp_done() to cancel the freshly initialized
work.

And if sk_user_data is already used by KCM, psock->strp should not be
touched, particularly strp->work state, so we need to move strp_init()
after the csk->sk_user_data check.

This also makes a lockdep warning reported by syzbot go away.

David Thompson 3a1a274e93 mlxbf_gige: compute MDIO period based on i1clk
This patch adds logic to compute the MDIO period based on
the i1clk, and thereafter write the MDIO period into the YU
MDIO config register. The i1clk resource from the ACPI table
is used to provide addressing to YU bootrecord PLL registers.
The values in these registers are used to compute MDIO period.
If the i1clk resource is not present in the ACPI table, then
the current default hardcorded value of 430Mhz is used.
The i1clk clock value of 430MHz is only accurate for boards
with BF2 mid bin and main bin SoCs. The BF2 high bin SoCs
have i1clk = 500MHz, but can support a slower MDIO period.

Sander Vanheule ee0175b3b4 gpio: realtek-otto: switch to 32-bit I/O
By using 16-bit I/O on the GPIO peripheral, which is apparently not safe
on MIPS, the IMR can end up containing garbage. This then results in
interrupt triggers for lines that don't have an interrupt handler
associated. The irq_desc lookup fails, and the ISR will not be cleared,
keeping the CPU busy until reboot, or until another IMR operation
restores the correct value. This situation appears to happen very
rarely, for < 0.5% of IMR writes.

Instead of using 8-bit or 16-bit I/O operations on the 32-bit memory
mapped peripheral registers, switch to using 32-bit I/O only, operating
on the entire bank for all single bit line settings. For 2-bit line
settings, with 16-bit port values, stick to manual (un)packing.

This issue has been seen on RTL8382M (HPE 1920-16G), RTL8391M (Netgear
GS728TP v2), and RTL8393M (D-Link DGS-1210-52 F3, Zyxel GS1900-48).

If cache_size < 0, then the OPEN request is expected to fail,

Duoming Zhou c0955bf957 ethernet: rocker: fix sleep in atomic context bug in neigh_timer_handler
The function neigh_timer_handler() is a timer handler that runs in an
atomic context. When used by rocker, neigh_timer_handler() calls
"kzalloc(.., GFP_KERNEL)" that may sleep. As a result, the sleep in
atomic context bug will happen. One of the processes is shown below:

ofdpa_fib4_add()
 ...
 neigh_add_timer()

(wait a timer)

neigh_timer_handler()
 neigh_release()
  neigh_destroy()
   rocker_port_neigh_destroy()
    rocker_world_port_neigh_destroy()
     ofdpa_port_neigh_destroy()
      ofdpa_port_ipv4_neigh()
       kzalloc(sizeof(.., GFP_KERNEL) //may sleep

This patch changes the gfp_t parameter of kzalloc() from GFP_KERNEL to
GFP_ATOMIC in order to mitigate the bug.

Haibo Chen 518e26f11a gpio: pca953x: Add mutex_lock for regcache sync in PM
The regcache sync will set the cache_bypass = true, at that
time, when there is regmap write operation, it will bypass
the regmap cache, then the regcache sync will write back the
value from cache to register, which is not as our expectation.

Though regmap already use its internal lock to avoid such issue,
but this driver force disable the regmap internal lock in its
regmap config: disable_locking = true

To avoid this issue, use the driver's own lock to do the protect
in system PM.
