[ Upstream commit bf94ec093d ]
The DSI host might be left in some state by the bootloader. If this
state generates an IRQ, it might hang the system by holding the
interrupt line before the driver sets up the DSI host to the known
state.
Move the request_irq into msm_dsi_host_init and pass IRQF_NO_AUTOEN to
it. Call enable/disable_irq after msm_dsi_host_power_on/_off()
functions, so that we can be sure that the interrupt is delivered when
the host is in the known state.
It is not possible to defer the interrupt enablement to a later point,
because drm_panel_prepare might need to communicate with the panel over
the DSI link and that requires working interrupt.

Use of percpu_counter structure to track count of orphaned

As explained in commit cf86a086a1 ("net/dst: use a smaller percpu_counter
batch for dst entries accounting"), default batch size is too big
for the default value of tcp_max_orphans (262144).
But even if we reduce batch sizes, there would still be cases
where the estimated count of orphans is beyond the limit,
and where tcp_too_many_orphans() has to call the expensive
percpu_counter_sum_positive().
One solution is to use plain per-cpu counters, and have
a timer to periodically refresh this cache.
Updating this cache every 100ms seems about right, tcp pressure
state is not radically changing over shorter periods.
percpu_counter was nice 15 years ago while hosts had less
than 16 cpus, not anymore by current standards.

Most of the txpower for the ath10k firmware is stored as twicepower (0.5 dB
steps). This isn't the case for max_antenna_gain - which is still expected
by the firmware as dB.
The firmware is converting it from dB to the internal (twicepower)
representation when it calculates the limits of a channel. This can be seen
in tpc_stats when configuring "12" as max_antenna_gain. Instead of the
expected 12 (6 dB), the tpc_stats shows 24 (12 dB).
Tested on QCA9888 and IPQ4019 with firmware 10.4-3.5.3-00057.

[ Upstream commit eb0782bbdf ]
The current IMA ruleset is identified by the variable "ima_rules"
that default to "&ima_default_rules". When loading a custom policy
for the first time, the variable is updated to "&ima_policy_rules"
instead. That update isn't RCU-safe, and deadlocks are possible.
Indeed, some functions like ima_match_policy() may loop indefinitely
when traversing "ima_default_rules" with list_for_each_entry_rcu().
When iterating over the default ruleset back to head, if the list
head is "ima_default_rules", and "ima_rules" have been updated to
"&ima_policy_rules", the loop condition (&entry->list != ima_rules)
stays always true, traversing won't terminate, causing a soft lockup
and RCU stalls.
Introduce a temporary value for "ima_rules" when iterating over
the ruleset to avoid the deadlocks.

Currently mtk_rng_runtime_suspend/resume is called for both runtime pm
and system sleep operations.
This is wrong as these should only be runtime ops as the name already
suggests. Currently freezing the system will lead to a call to
mtk_rng_runtime_suspend even if the device currently isn't active. This
leads to a clock warning because it is disabled/unprepared although it
isn't enabled/prepared currently.
This patch fixes this by only setting the runtime pm ops and forces to
call the runtime pm ops from the system sleep ops as well if active but
not otherwise.

AMD Rome systems and later support interleaving between three identical
ranks within a channel.
Check for this mode by counting the number of enabled chip selects and
comparing their masks. If there are exactly three enabled chip selects
and their masks are identical, then three rank interleaving is enabled.
The size of a rank is determined from its mask value. However, three
rank interleaving doesn't follow the method of swapping an interleave
bit with the most significant bit. Rather, the interleave bit is flipped
and the most significant bit remains the same. There is only a single
interleave bit in this case.
Account for this when determining the chip select size by keeping the
most significant bit at its original value and ignoring any zero bits.
This will return a full bitmask in [MSB:1].

[ Upstream commit 4925642d54 ]
In tests with two Lima boards from 8devices (QCA4531 based) on OpenWrt
19.07 we could force a silent restart of a device with no serial
output when we were sending a high amount of UDP traffic (iperf3 at 80
MBit/s in both directions from external hosts, saturating the wifi and
causing a load of about 4.5 to 6) and were then triggering an
ath9k_queue_reset().
Further debugging showed that the restart was caused by the ath79
watchdog. With disabled watchdog we could observe that the device was
constantly going into ath_isr() interrupt handler and was returning
early after the ATH_OP_HW_RESET flag test, without clearing any
interrupts. Even though ath9k_queue_reset() calls
ath9k_hw_kill_interrupts().
With JTAG we could observe the following race condition:
1) ath9k_queue_reset()
...
-> ath9k_hw_kill_interrupts()
-> set_bit(ATH_OP_HW_RESET, &common->op_flags);
...
<- returns
2) ath9k_tasklet()
...
-> ath9k_hw_resume_interrupts()
...
<- returns
3) loops around:
...
handle_int()
-> ath_isr()
...
-> if (test_bit(ATH_OP_HW_RESET,
&common->op_flags))
return IRQ_HANDLED;
x) ath_reset_internal():
=> never reached <=
And in ath_isr() we would typically see the following interrupts /
interrupt causes:
* status: 0x00111030 or 0x00110030
* async_cause: 2 (AR_INTR_MAC_IPQ)
* sync_cause: 0
So the ath9k_tasklet() reenables the ath9k interrupts
through ath9k_hw_resume_interrupts() which ath9k_queue_reset() had just
disabled. And ath_isr() then keeps firing because it returns IRQ_HANDLED
without actually clearing the interrupt.
To fix this IRQ storm also clear/disable the interrupts again when we
are in reset state.

debugfs_create_file() takes a pointer argument that can be used during
file operation callbacks (accessible via i_private in the inode
structure). An obvious requirement is for the pointer to refer to
valid memory when used.
When creating the debugfs file to dynamically enable / disable
kprobes, a pointer to local variable is passed to
debugfs_create_file(); which will go out of scope when the init
function returns. The reason this hasn't triggered random memory
corruption is because the pointer is not accessed during the debugfs
file callbacks.
Since the enabled state is managed by the kprobes_all_disabled global
variable, the local variable is not needed. Fix the incorrect (and
unnecessary) usage of local variable during debugfs_file_create() by
passing NULL instead.

The runtime enabling of the ISPCK (internally clocks the pipeline inside
the ISC) has to be done after the pm_runtime for the ISC dev has been
started.
After the commit by Mauro:
the ISC failed to probe with the error:
atmel-sama5d2-isc f0008000.isc: failed to enable ispck: -13
atmel-sama5d2-isc: probe of f0008000.isc failed with error -13
This is because the enabling of the ispck is done too early in the probe,
and the PM runtime returns invalid request.
Thus, moved this clock enabling after pm_runtime_idle is called.
The ISPCK is required only for sama5d2 type of ISC.
Thus, add a bool inside the isc struct that is platform dependent.
For the sama7g5-isc, the enabling of the ISPCK is wrong and does not make
sense. Removed it from the sama7g5 probe. In sama7g5-isc, there is only
one clock, the MCK, which also clocks the internal pipeline of the ISC.
Adapted the clk_prepare and clk_unprepare to request the runtime PM
for both clocks (MCK and ISPCK) in case of sama5d2-isc, and the single
clock (MCK) in case of sama7g5-isc.
