We have found a hardware erratum on 82599 hardware that can lead to
unpredictable behavior when Header Splitting mode is enabled. So
we are no longer enabling this feature on affected hardware.
Please see the 82599 Specification Update for more information.

Currently the driver increments the tx_timeout counter (an error counter)
when simply resetting the part with outstanding transmit work pending.
This is an unnecessary count of an error, when all we should be doing is
just resetting the part and discarding the transmits. With this change the
only increment of tx_timeout is when the stack calls the watchdog reset
function due to a true Tx timeout.

Following symptoms were observed:
1. After raid0->raid10 takeover operation we have array with 2
missing disks.
When we add disk for rebuild, recovery process starts as expected
but it does not finish- it stops at about 90%, md126_resync process
hangs in "D" state.
2. Similar behavior is when we have mounted raid0 array and we
execute takeover to raid10. After this when we try to unmount array-
it causes process umount hangs in "D"
In scenarios above processes hang at the same function- wait_barrier
in raid10.c.
Process waits in macro "wait_event_lock_irq" until the
"!conf->barrier" condition will be true.
In scenarios above it never happens.
Reason was that at the end of level_store, after calling pers->run,
we call mddev_resume. This calls pers->quiesce(mddev, 0) with
RAID10, that calls lower_barrier.
However raise_barrier hadn't been called on that 'conf' yet,
so conf->barrier becomes negative, which is bad.
This patch introduces setting conf->barrier=1 after takeover
operation. It prevents to become barrier negative after call
lower_barrier().

md_make_request was calling bio_sectors() for part_stat_add
after it was calling the make_request function. This is
bad because the make_request function can free the bio and
because the bi_size field can change around.
The fix here was suggested by Jens Axboe. It saves the
sector count before the make_request call. I hit this
with CONFIG_DEBUG_PAGEALLOC turned on while trying to break
his pretty fusionio card.

The set_type function of the pmic irq chip is a horrible hack. It
schedules work because it cannot access the scu chip from the set_type
function. That breaks the assumption, that the type is set after
set_type has returned.
irq_chips provide buslock functions to avoid the above. Convert the
driver to use the proper model.

commit 456dc301([PATCH] intel_pmic_gpio: modify EOI handling following
change of kernel irq subsystem) changes
- desc->chip->eoi(irq);
+
+ if (desc->chip->irq_eoi)
+ desc->chip->irq_eoi(irq_get_irq_data(irq));
+ else
+ dev_warn(pg->chip.dev, "missing EOI handler for irq %d\n", irq);
With the following explanation:
"Latest kernel has many changes in IRQ subsystem and its interfaces,
like adding irq_eoi" for struct irq_chip, this patch will make it
support both the new and old interface."
This is completely bogus.
#1) The changelog does not match the patch at all
#2) This driver relies on the assumption that it sits behind an eoi
capable interrupt line. If the implementation of the underlying
chip changes from eoi to irq_eoi then this driver has to follow
that change and not add a total bogosity.
Remove the sillyness and retrieve the interrupt data from irq_desc
directly. No need to got through circles to look it up.

This is due to the missing include of linux/usb/composite.h - this patch
adds the missing include.
In addition there's also a problem in fsg_common_init() where we memset
'common', but we use the size of a pointer to 'struct fsg_common' as the
size argument to memset(), not the actual size of the struct. This patch
fixes the sizeof so we zero the entire struct as intended.

In drm_crtc_helper_set_config, instead of always forcing all outputs
to DRM_MODE_DPMS_ON, only set them if the CRTC is actually getting a
mode set, as any mode set will turn all outputs on.

While the RxFIFO interruption is masked for most 8168, nothing prevents
it to appear in the irq status word. This is no excuse to crash.

Some experiment-based action to prevent my 8168 chipsets locking-up hard
in the irq handler under load (pktgen ~1Mpps). Apparently a reset is not
always mandatory (is it at all ?).
- RTL_GIGA_MAC_VER_12
- RTL_GIGA_MAC_VER_25
Missed ~55% packets. Note:
- this is an old SiS 965L motherboard
- the 8168 chipset emits (lots of) control frames towards the sender
- RTL_GIGA_MAC_VER_26
The chipset does not go into a frenzy of mac control pause when it
crashes yet but it can still be crashed. It needs more work.

I found that one of the 8168c chipsets (concretely XID 1c4000c0) starts
generating RxFIFO overflow errors. The result is an infinite loop in
interrupt handler as the RxFIFOOver is handled only for ...MAC_VER_11.
With the workaround everything goes fine.

The comments under "config STUB_POULSBO" are close to correct,
but they are not being followed. This patch updates them to reflect
the requirements for THERMAL.
This build error is caused by STUB_POULSBO selecting ACPI_VIDEO
when ACPI_VIDEO's config requirements are not met.

The USB core keeps track of pending resume requests for root hubs, in
order to resolve races between wakeup requests and suspends. However
the code that does this is subject to another race (between wakeup
requests and resumes) because the WAKEUP_PENDING flag is cleared
before the resume occurs, leaving a window in which another wakeup
request might arrive.
This patch (as1447) fixes the problem by clearing the WAKEUP_PENDING
flag after the resume instead of before it.
This fixes Bugzilla #24952.

If anyone comes across a high-speed hub that (by mistake or by design)
claims to have no Transaction Translators, plugging a full- or
low-speed device into it will cause the USB stack to crash. This
patch (as1446) prevents the problem by ignoring such devices, since
the kernel has no way to communicate with them.

In drivers/usb/host/sl811-hcd.c::sl811h_urb_enqueue(), memory is allocated
with kzalloc() and assigned to 'ep'. If we leave via the 'fail' label due
to 'if (ep->maxpacket > H_MAXPACKET)', then 'ep' will go out of scope
without having been assigned to anything, so we'll leak the memory we
allocated.
This patch fixes the leak by simply calling kfree(ep); before jumping to
the 'fail' label.

As reported by Flavio Leitner, there is no synchronization to protect
NIU's get_stats method from seeing a NULL pointer in either
np->rx_rings or np->tx_rings. In fact, as far as ->ndo_get_stats
is concerned, these values are set completely asynchronously.
Flavio attempted to fix this using a RW semaphore, which in fact
works most of the time. However, dev_get_stats() can be invoked
from non-sleepable contexts in some cases, so this fix doesn't
work in all cases.
So instead, control the visibility of the np->{rx,tx}_ring pointers
when the device is being brough up, and use properties of the device
down sequence to our advantage.
In niu_get_stats(), return immediately if netif_running() is false.
The device shutdown sequence first marks the device as not running (by
clearing the __LINK_STATE_START bit), then it performans a
synchronize_rcu() (in dev_deactive_many()), and then finally it
invokes the driver ->ndo_stop() method.
This guarentees that all invocations of niu_get_stats() either see
netif_running() as false, or they see the channel pointers before
->ndo_stop() clears them out.
If netif_running() is true, protect against startup races by loading
the np->{rx,tx}_rings pointer into a local variable, and punting if
it is NULL. Use ACCESS_ONCE to prevent the compiler from reloading
the pointer on us.
Also, during open, control the order in which the pointers and the
ring counts become visible globally using SMP write memory barriers.
We make sure the np->num_{rx,tx}_rings value is stable and visible
before np->{rx,tx}_rings is.
Such visibility control is not necessary on the niu_free_channels()
side because of the RCU sequencing that happens during device down as
described above. We are always guarenteed that all niu_get_stats
calls are finished, or will see netif_running() false, by the time
->ndo_stop is invoked.
