Since commit 2d984ad1 (PM / QoS: Introcuce latency tolerance device
PM QoS type) we reassign "c" to point at qos->latency_tolerance before
freeing c->notifiers, but the notifiers field of latency_tolerance is
never used.

Restore the original behaviour of freeing the notifiers pointer on
qos->resume_latency, which is used, and fix the following kmemleak
warning.

Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular

This utility can be used in two ways:

 - If there is Linux trace file with pstate_sample events enabled, then
   this utility can parse the trace file and generate performance plots.

 - If user has not specified a trace file as input via command line

There are two reasons for reporting wakeup event when dedicated wakeup
IRQ is triggered:

- wakeup events accounting, so proper statistical data will be
  displayed in sysfs and debugfs;

- there are small window when System is entering suspend during which
  dedicated wakeup IRQ can be lost:

dpm_suspend_noirq()
  |- device_wakeup_arm_wake_irqs()
      |- dev_pm_arm_wake_irq(X)
         |- IRQ is enabled and marked as wakeup source
[1]...
  |- suspend_device_irqs()
     |- suspend_device_irq(X)
	|- irqd_set(X, IRQD_WAKEUP_ARMED);
	   |- wakup IRQ armed

The wakeup IRQ can be lost if it's triggered at point [1]
and not armed yet.

Hence, fix above cases by adding simple pm_wakeup_event() call in
handle_threaded_wake_irq().

Dedicated wakeirq is a one time event to wake-up the system from
low-power state and then call pm_runtime_resume() on the device wired
with the dedicated wakeirq.

Sometimes dedicated wakeirqs can get deferred if they trigger after we
call disable_irq_nosync() in dev_pm_disable_wake_irq(). This can happen
if pm_runtime_get() is called around the same time a wakeirq fires.

If an interrupt fires after disable_irq_nosync(), by default it will get
tagged with IRQS_PENDING and will run later on when the interrupt is
enabled again.

Deferred wakeirqs usually just produce pointless wake-up events. But they
can also cause suspend to fail if the deferred wakeirq fires during
dpm_suspend_noirq() for example. So we really don't want to see the
deferred wakeirqs triggering after the device has resumed.

Let's fix the issue by setting IRQ_DISABLE_UNLAZY flag for the dedicated
wakeirqs. The other option would be to implement irq_disable() in the
dedicated wakeirq controller, but that's not a generic solution.

For reference below is what happens with a IRQ_TYPE_EDGE_BOTH IRQ
type wakeirq:

- resume by dedicated IRQ (EDGE_FALLING)
 - suspend_enter()
  ....
 - arch_suspend_enable_irqs()
   |- dedicated IRQ armed and fired
   |- irq_pm_check_wakeup()
      |- disarm, disable IRQ and mark as IRQS_PENDING
  ....
 - dpm_resume_noirq()
   |- resume_device_irqs()
      |- __enable_irq()
         |- check_irq_resend()
            |- handle_threaded_wake_irq()
 	       |- dedicated IRQ processed
   |- device_wakeup_disarm_wake_irqs()
      |- disable_irq_wake()
  ....
 !-> dedicated IRQ (EDGE_RISING)
     -| handle_edge_irq()
        |- IRQ disabled: mask_ack_irq and mark as IRQS_PENDING
  ....
- subsequent suspend
  ....
  |- dpm_suspend_noirq()
     |- device_wakeup_arm_wake_irqs()
        |- __enable_irq()
           |- check_irq_resend()
(a)           |- handle_threaded_wake_irq()
                 |- pm_wakeup_event() --> abort suspend
  ....
     |- suspend_device_irqs()
        |- suspend_device_irq()
           |-  dedicated IRQ armed
  ....
(b)  |- resend_irqs
        |- irq_pm_check_wakeup()
           |- IRQ armed -> abort suspend

because of pending IRQ System suspend can be aborted at points
(a)-not armed or (b)-armed.

We currently rely on runtime PM to enable dedicated wakeirq for suspend.
This assumption fails in the following two cases:

1. If the consumer driver does not have runtime PM implemented, the
   dedicated wakeirq never gets enabled for suspend

2. If the consumer driver has runtime PM implemented, but does not idle
   in suspend

Let's fix the issue by always enabling the dedicated wakeirq during
suspend.

If btrfs_decompress_buf2page() is handed a bio with its page in the
middle of the working buffer, then we adjust the offset into the working
buffer. After we copy into the bio, we advance the iterator by the
number of bytes we copied. Then, we have some logic to handle the case
of discontiguous pages and adjust the offset into the working buffer
again. However, if we didn't advance the bio to a new page, we may enter
this case in error, essentially repeating the adjustment that we already
made when we entered the function. The end result is bogus data in the
bio.

Previously, we only checked for this case when we advanced to a new
page, but the conversion to bio iterators changed that. This restores
the old, correct behavior.

A case I saw when testing with zlib was:

    buf_start = 42769
    total_out = 46865
    working_bytes = total_out - buf_start = 4096
    start_byte = 45056

The condition (total_out > start_byte && buf_start < start_byte) is
true, so we adjust the offset:

    buf_offset = start_byte - buf_start = 2287
    working_bytes -= buf_offset = 1809
    current_buf_start = buf_start = 42769

Then, we copy

    bytes = min(bvec.bv_len, PAGE_SIZE - buf_offset, working_bytes) = 1809
    buf_offset += bytes = 4096
    working_bytes -= bytes = 0
    current_buf_start += bytes = 44578

After bio_advance(), we are still in the same page, so start_byte is the
same. Then, we check (total_out > start_byte && current_buf_start < start_byte),
which is true! So, we adjust the values again:

    buf_offset = start_byte - buf_start = 2287
    working_bytes = total_out - start_byte = 1809
    current_buf_start = buf_start + buf_offset = 45056

But note that working_bytes was already zero before this, so we should
have stopped copying.

   - We weren't marking host IPIs properly for KVM in the OPAL ICP
     backend.

   - The ERAT flushing on radix was missing an isync and was incorrectly
     marked as DD1 only.

   - The powernv CPU hotplug code was missing a wakeup type and failing
     to flush the interrupt correctly when using OPAL ICP

  Thanks to Benjamin Herrenschmidt"

udp_ioctl(), as its name suggests, is used by UDP protocols,
but is also used by L2TP :(

L2TP should use its own handler, because it really does not
look the same.

SIOCINQ for instance should not assume UDP checksum or headers.

Thanks to Andrey and syzkaller team for providing the report
and a nice reproducer.

While crashes only happen on recent kernels (after commit
7c13f97f ("udp: do fwd memory scheduling on dequeue")), this
probably needs to be backported to older kernels.

rx_refill_timer should be deleted as soon as we disconnect from the
backend since otherwise it is possible for the timer to go off before
we get to xennet_destroy_queues(). If this happens we may dereference
queue->rx.sring which is set to NULL in xennet_disconnect_backend().

If a USB-to-serial adapter is unplugged, the driver re-initializes, with
dev->hard_header_len and dev->addr_len set to zero, instead of the correct
values.  If then a packet is sent through the half-dead interface, the
kernel will panic due to running out of headroom in the skb when pushing
for the AX.25 headers resulting in this panic:

[<c0595468>] (skb_panic) from [<c0401f70>] (skb_push+0x4c/0x50)
[<c0401f70>] (skb_push) from [<bf0bdad4>] (ax25_hard_header+0x34/0xf4 [ax25])
[<bf0bdad4>] (ax25_hard_header [ax25]) from [<bf0d05d4>] (ax_header+0x38/0x40 [mkiss])
[<bf0d05d4>] (ax_header [mkiss]) from [<c041b584>] (neigh_compat_output+0x8c/0xd8)
[<c041b584>] (neigh_compat_output) from [<c043e7a8>] (ip_finish_output+0x2a0/0x914)
[<c043e7a8>] (ip_finish_output) from [<c043f948>] (ip_output+0xd8/0xf0)
[<c043f948>] (ip_output) from [<c043f04c>] (ip_local_out_sk+0x44/0x48)

This patch makes mkiss behave like the 6pack driver. 6pack does not
panic.  In 6pack.c sp_setup() (same function name here) the values for
dev->hard_header_len and dev->addr_len are set to the same values as in
my mkiss patch.

This patch fixes the device being used to DMA map skb->data.
Erroneous device assignment causes the crash when SMMU is enabled.
This happens during TX since buffer gets DMA mapped with device
correspondign to net_device and gets unmapped using the device
related to DSAF.
