Smatch complains about the locking here because we mix spin_lock_irq()
with spin_lock_irqsave() in an unusual way. According to Smatch, it's
not always clear if the IRQs are enabled or disabled when we return. It
turns out this function is always called with IRQs enabled and we can
just use spin_lock_irq().
It's called from __enqueue_in_driver().

Reading firmware status register to detect whether firmware is
running or not didn't worked 100% reliably. That register was
likely set by firmware itself which means it could not contain
reasonable values until firmware is up and running. Usually it
just worked as some garbage value was returned accidentally but it
appears that in some cases returned garbage value was 0x00 which
was considered "firmware is up and running" by the driver and
firmware loading was skipped leaving device to non-working state.
Fix problem by removing unreliable check and let the driver keep
count whether firmware is loaded or not.

In the following scenario the socket is corked:
If the first UDP packet is larger then the mtu we try to append it to the
write queue via ip6_ufo_append_data. A following packet, which is smaller
than the mtu would be appended to the already queued up gso-skb via
plain ip6_append_data. This causes random memory corruptions.
In ip6_ufo_append_data we also have to be careful to not queue up the
same skb multiple times. So setup the gso frame only when no first skb
is available.
This also fixes a shortcoming where we add the current packet's length to
cork->length but return early because of a packet > mtu with dontfrag set
(instead of sutracting it again).
Found with trinity.

In my patch c194992cbe71c20bb3623a566af8d11b0bfaa721 ("skge: fix
broken driver") I didn't fix the skge bug correctly. The value of the
new mapping (not old) was passed to pci_unmap_single.
If we enable CONFIG_DMA_API_DEBUG, it results in this warning:
WARNING: CPU: 0 PID: 0 at lib/dma-debug.c:986 check_sync+0x4c4/0x580()
skge 0000:02:07.0: DMA-API: device driver tries to sync DMA memory it has
not allocated [device address=0x000000023a0096c0] [size=1536 bytes]
This patch makes the skge driver pass the correct value to
pci_unmap_single and fixes the warning. It copies the old descriptor to
on-stack variable "ee" and unmaps it if mapping of the new descriptor
succeeded.
This patch should be backported to 3.11-stable.

There are two locks involved in managing the journal lists. The general
reiserfs_write_lock and the journal->j_flush_mutex.
While flush_journal_list is sleeping to acquire the j_flush_mutex or to
submit a block for write, it will drop the write lock. This allows
another thread to acquire the write lock and ultimately call
flush_used_journal_lists to traverse the list of journal lists and
select one for flushing. It can select the journal_list that has just
had flush_journal_list called on it in the original thread and call it
again with the same journal_list.
The second thread then drops the write lock to acquire j_flush_mutex and
the first thread reacquires it and continues execution and eventually
clears and frees the journal list before dropping j_flush_mutex and
returning.
The second thread acquires j_flush_mutex and ends up operating on a
journal_list that has already been released. If the memory hasn't
been reused, we'll soon after hit a BUG_ON because the transaction id
has already been cleared. If it's been reused, we'll crash in other
fun ways.
Since flush_journal_list will synchronize on j_flush_mutex, we can fix
the race by taking a proper reference in flush_used_journal_lists
and checking to see if it's still valid after the mutex is taken. It's
safe to iterate the list of journal lists and pick a list with
just the write lock as long as a reference is taken on the journal list
before we drop the lock. We already have code to handle whether a
transaction has been flushed already so we can use that to handle the
race and get rid of the trans_id BUG_ON.

Commit a3172027 introduced test_transaction as a requirement for
flushing old lists -- but it can never return 1 unless the transaction
has already been flushed.
As a result, we have a routine that iterates the j_realblocks list but
doesn't actually do anything. Since it's been this way since 2006 and
the latency numbers were what Chris expected, let's just rip it out.

drm/i915: avoid big kmallocs on reading error state
we introduce a two-pass mechanism for splitting long strings being
formatted into the error-state. The first pass finds the length, and the
second pass emits the right portion of the string into the accumulation
buffer. Unfortunately we use the same va_list for both passes, resulting
in the second pass reading garbage off the end of the argument list. As
the two passes are only used for boundaries between read() calls, the
corruption is only rarely seen.
This fixes the root cause behind

When a device signals remote wakeup on a roothub, and the suspend change
bit is set, the host controller driver must not give control back to the
USB core until the port goes back into the active state.
EHCI accomplishes this by waiting in the get port status function until
the PORT_RESUME bit is cleared:
/* stop resume signaling */
temp &= ~(PORT_RWC_BITS | PORT_SUSPEND | PORT_RESUME);
ehci_writel(ehci, temp, status_reg);
clear_bit(wIndex, &ehci->resuming_ports);
retval = ehci_handshake(ehci, status_reg,
PORT_RESUME, 0, 2000 /* 2msec */);
Similarly, the xHCI host should wait until the port goes into U0, before
passing control up to the USB core. When the port transitions from the
RExit state to U0, the xHCI driver will get a port status change event.
We need to wait for that event before passing control up to the USB
core.
After the port transitions to the active state, the USB core should time
a recovery interval before it talks to the device. The length of that
recovery interval is TRSMRCY, 10 ms, mentioned in the USB 2.0 spec,
section 7.1.7.7. The previous xHCI code (which did not wait for the
port to go into U0) would cause the USB core to violate that recovery
interval.
This bug caused numerous USB device disconnects on remote wakeup under
ChromeOS and a Lynx Point LP xHCI host that takes up to 20 ms to move
from RExit to U0. ChromeOS is very aggressive about power savings, and
sets the autosuspend_delay to 100 ms, and disables USB persist.
I attempted to replicate this bug with Ubuntu 12.04, but could not. I
used Ubuntu 12.04 on the same platform, with the same BIOS that the bug
was triggered on ChromeOS with. I also changed the USB sysfs settings
as described above, but still could not reproduce the bug under Ubuntu.
It may be that ChromeOS userspace triggers this bug through additional
settings.

If a command on the command ring needs to be cancelled before it is handled
it can be turned to a no-op operation when the ring is stopped.
We want to store the command ring enqueue pointer in the command structure
when the command in enqueued for the cancellation case.
Some commands used to store the command ring dequeue pointers instead of enqueue
(these often worked because enqueue happends to equal dequeue quite often)
Other commands correctly used the enqueue pointer but did not check if it pointed
to a valid trb or a link trb, this caused for example stop endpoint command to timeout in
xhci_stop_device() in about 2% of suspend/resume cases.
This should also solve some weird behavior happening in command cancellation cases.
This patch is based on a patch submitted by Sarah Sharp to linux-usb, but
then forgotten:

When a command times out, the command ring is first aborted,
and then stopped. If the command ring is empty when it is stopped
the stop event will point to next command which is not yet set.
xHCI tries to handle this next event often causing an oops.
Don't handle command completion events on stopped cmd ring if ring is
empty.

During flows which mask block attentions (e.g., register dump) all parities
are masked. However, unlike other blocks the MCP's attention is not masked
inside the block but rather the indication to the driver. If another attention
(e.g., link change) will occour while there's an MCP parity, the driver will
ignore the fact that the parity is masked and erroneously report a parity.
This patch forces the driver to read the MCP masking while checking for
parities.

Move probe out of __init section and don't use platform_driver_probe
which cannot be used with deferred probing.
Since commit e9354576 ("gpiolib: Defer failed gpio requests by default")
and 04bf3011 ("regulator: Support driver probe deferral") this driver
might return -EPROBE_DEFER if a gpio_request or regulator_get fails.

Starting with UVD3 message and feedback buffers have their
own 256MB segment, so no need to force them into VRAM any more.

Allow user to change the number of IOs that are reserved by
bio-based DM's mempools by writing to this file:
/sys/module/dm_mod/parameters/reserved_bio_based_ios
The default value is RESERVED_BIO_BASED_IOS (16). The maximum allowed
value is RESERVED_MAX_IOS (1024).
Export dm_get_reserved_bio_based_ios() for use by DM targets and core
code. Switch to sizing dm-io's mempool and bioset using DM core's
configurable 'reserved_bio_based_ios'.

Bio-based device mapper processing doesn't need larger mempools (like
request-based DM does), so lower the number of reserved entries for
bio-based operation. 16 was already used for bio-based DM's bioset
but mistakenly wasn't used for it's _io_cache.
Formalize difference between bio-based and request-based defaults by
introducing RESERVED_BIO_BASED_IOS and RESERVED_REQUEST_BASED_IOS.
