commit 01ac8794a77192236a4b91c33adf4177ac5a21f0 upstream.
We need to reorder the driver init sequence to better accomodate
dpm which needs to be loaded earlier in the init sequence. Move
fw init up so that it's available for dpm init.

commit 6375b768a9850b6154478993e5fb566fa4614a9c upstream.
Single-link DVI max dotclock is 165MHz. Filter out modes with higher
dotclock when the monitor doesn't support HDMI.
Modes higher than 165 MHz were allowed in

commit bcdb72ac7c00d2b56359fc82bcc8fe50454717d5 upstream.
pci_get_class(class, from) drops the refcount for 'from', so the
extra pci_dev_put we do on it will result in a use after free bug
starting with the WARN below.

commit 70335abb2689c8cd5df91bf2d95a65649addf50b upstream.
The expected logic of proc_map_files_get_link() is either to return 0
and initialize 'path' or return an error and leave 'path' uninitialized.
By the time dname_to_vma_addr() returns 0 the corresponding vma may have
already be gone. In this case the path is not initialized but the
return value is still 0. This results in 'general protection fault'
inside d_path().
Steps to reproduce:
CONFIG_CHECKPOINT_RESTORE=y
fd = open(...);
while (1) {
mmap(fd, ...);
munmap(fd, ...);
}
ls -la /proc/$PID/map_files

commit a2a99cea5ec7c1e47825559f0e75a4efbcf8aee3 upstream.
This patch fixes a bug in iscsit_get_tpg_from_np() where the
tpg->tpg_state sanity check was looking for TPG_STATE_FREE,
instead of != TPG_STATE_ACTIVE.
The latter is expected during a normal TPG shutdown once the
tpg_state goes into TPG_STATE_INACTIVE in order to reject any
new incoming login attempts.

commit b6b87a1df604678ed1be40158080db012a99ccca upstream.
This patch fixes the incorrect setting of ->post_send_buf_count
related to RDMA WRITEs + READs where isert_rdma_rw->send_wr_num
was not being taken into account.
This includes incrementing ->post_send_buf_count within
isert_put_datain() + isert_get_dataout(), decrementing within
__isert_send_completion() + isert_response_completion(), and
clearing wr->send_wr_num within isert_completion_rdma_read()
This is necessary because even though IB_SEND_SIGNALED is
not set for RDMA WRITEs + READs, during a QP failure event
the work requests will be returned with exception status
from the TX completion queue.

commit 9bb4ca68fc48eea618b1af1c1cde2a251ae32d1b upstream.
This patch changes IB_WR_FAST_REG_MR + IB_WR_LOCAL_INV related
work requests to include a ISER_FRWR_LI_WRID value in order to
signal isert_cq_tx_work() that these requests should be ignored.
This is necessary because even though IB_SEND_SIGNALED is not

requests will be returned with exception status from the TX
completion queue.

commit defd884845297fd5690594bfe89656b01f16d87e upstream.
This patch addresses a couple of different hug shutdown issues
related to wait_event() + isert_conn->state. First, it changes
isert_conn->conn_wait + isert_conn->conn_wait_comp_err from
waitqueues to completions, and sets ISER_CONN_TERMINATING from
within isert_disconnect_work().
Second, it splits isert_free_conn() into isert_wait_conn() that
is called earlier in iscsit_close_connection() to ensure that
all outstanding commands have completed before continuing.
Finally, it breaks isert_cq_comp_err() into seperate TX / RX
related code, and adds logic in isert_cq_rx_comp_err() to wait
for outstanding commands to complete before setting ISER_CONN_DOWN
and calling complete(&isert_conn->conn_wait_comp_err).

commit 5159d763f60af693a3fcec45dce2021f66e528a4 upstream.
There are a handful of uses of list_empty() for cmd->i_conn_node

This patch changes all uses of list_del -> list_del_init in order

commit a4e90bed511220ff601d064c9e5d583e91308f65 upstream.
If the HW Reduced ACPI mode bit is set in the FADT, ACPICA uses
the optional sleep control and sleep status registers for making
the system enter sleep states (including S5), so it is not possible
to use system sleep states or power it off using ACPI if the HW
Reduced ACPI mode bit is set and those registers are not available.
For this reason, add a new function, acpi_sleep_state_supported(),
checking if the HW Reduced ACPI mode bit is set and whether or not
system sleep states are usable in that case in addition to checking
the return value of acpi_get_sleep_type_data() and make the ACPI
sleep setup routines use that function to check the availability of
system sleep states.
Among other things, this prevents the kernel from attempting to
use ACPI for powering off HW Reduced ACPI systems without the sleep
control and sleep status registers, because ACPI power off doesn't
have a chance to work on them. That allows alternative power off
mechanisms that may actually work to be used on those systems. The
affected machines include Dell Venue 8 Pro, Asus T100TA, Haswell
Desktop SDP and Ivy Bridge EP Demo depot.

commit e1253be0ece1a95a02c7f5843194877471af8179 upstream.
When nfs4_set_rw_stateid() can fails by returning EIO to indicate that
the stateid is completely invalid, then it makes no sense to have it
trigger a retry of the READ or WRITE operation. Instead, we should just
have it fall through and attempt a recovery.
This fixes an infinite loop in which the client keeps replaying the same
bad stateid back to the server.

commit 61d1cf163c8653934cc8cd5d0b2a562d0990c265 upstream.
The 'ath79_spi_setup_cs' function initializes the chip
select line of a given SPI device in order to make sure
that the device is inactive.
If the SPI_CS_HIGH bit is set for a given device, it
means that the CS line of that device is active HIGH
so it must be set to LOW initially. In case of GPIO
CS lines, the 'ath79_spi_setup_cs' function does the
opposite of that due to the wrong GPIO flags.
Fix the code to use the correct GPIO flags.

commit 83493d7e782d2630f1a55def14a79f0e7c4faac3 upstream.
We're now blacklisting "Crucial_CT???M500SSD1" and
"Crucial_CT???M500SSD3". Also, "Micron_M500*" is blacklisted which is
about the same devices as the crucial branded ones. Let's merge the
two Crucial M500 entries and widen the match to

M8 (2BA30001)
commit b28a613e9138e4b3a64649bd60b13436f4b4b49b upstream.
Via commit 87809942d3fa "libata: add ATA_HORKAGE_BROKEN_FPDMA_AA quirk
for Seagate Momentus SpinPoint M8" we added a quirk for disks named
"ST1000LM024 HN-M101MBB" with firmware revision "2AR10001".
As reported on https://bugzilla.redhat.com/show_bug.cgi?id=1073901,
we need to also add firmware revision 2BA30001 as it is broken as well.

commit 70044d71d31d6973665ced5be04ef39ac1c09a48 upstream.
PREPARE_[DELAYED_]WORK() are being phased out. They have few users
and a nasty surprise in terms of reentrancy guarantee as workqueue
considers work items to be different if they don't have the same work
function.
firewire core-device and sbp2 have been been multiplexing work items
with multiple work functions. Introduce fw_device_workfn() and
sbp2_lu_workfn() which invoke fw_device->workfn and
sbp2_logical_unit->workfn respectively and always use the two
functions as the work functions and update the users to set the
->workfn fields instead of overriding work functions using
PREPARE_DELAYED_WORK().
This fixes a variety of possible regressions since a2c1c57be8d9
"workqueue: consider work function when searching for busy work items"
due to which fw_workqueue lost its required non-reentrancy property.

commit 0ca49345b6f489e95f8d6edeb0b092e257475b2a upstream.
Since commit bd972688eb24
"firewire: ohci: Fix 'failed to read phy reg' on FW643 rev8",
there is a high chance that firewire-ohci fails to initialize LSI née
Agere controllers.
https://bugzilla.kernel.org/show_bug.cgi?id=65151
Peter Hurley points out the reason: IEEE 1394a:2000 clause 5A.1 (or
IEEE 1394:2008 clause 17.2.1) say: "The PHY shall insure that no more
than 10 ms elapse from the reassertion of LPS until the interface is
reset. The link shall not assert LReq until the reset is complete."
In other words, the link needs to give the PHY at least 10 ms to get
the interface operational.
With just the msleep(1) in bd972688eb24, the first read_phy_reg()
during ohci_enable() may happen before the phy-link interface reset was
finished, and fail. Due to the high variability of msleep(n) with small
n, this failure was not fully reproducible, and not apparent at all with
low CONFIG_HZ setting.
On the other hand, Peter can no longer reproduce the issue with FW643
rev8. The read phy reg failures that happened back then may have had an
unrelated cause. So, just revert bd972688eb24, except for the valid
comment on TSB82AA2 cards.

commit 45ab2813d40d88fc575e753c38478de242d03f88 upstream.
If a module fails to add its tracepoints due to module tainting, do not
create the module event infrastructure in the debugfs directory. As the events
will not work and worse yet, they will silently fail, making the user wonder
why the events they enable do not display anything.
Having a warning on module load and the events not visible to the users
will make the cause of the problem much clearer.

commit ad332c8a45330d170bb38b95209de449b31cd1b4 upstream.
A number of Samsung notebooks (530Uxx/535Uxx/540Uxx/550Pxx/900Xxx/etc)
continue to log events during sleep (lid open/close, AC plug/unplug,
battery level change), which accumulate in the EC until a buffer fills.
After the buffer is full (tests suggest it holds 8 events), GPEs stop
being triggered for new events. This state persists on wake or even on
power cycle, and prevents new events from being registered until the EC
is manually polled.
This is the root cause of a number of bugs, including AC not being
detected properly, lid close not triggering suspend, and low ambient
light not triggering the keyboard backlight. The bug also seemed to be
responsible for performance issues on at least one user's machine.
Juan Manuel Cabo found the cause of bug and the workaround of polling
the EC manually on wake.
The loop which clears the stale events is based on an earlier patch by
Lan Tianyu (see referenced attachment).
This patch:
- Adds a function acpi_ec_clear() which polls the EC for stale _Q
events at most ACPI_EC_CLEAR_MAX (currently 100) times. A warning is
logged if this limit is reached.
- Adds a flag EC_FLAGS_CLEAR_ON_RESUME which is set to 1 if the DMI
system vendor is Samsung. This check could be replaced by several
more specific DMI vendor/product pairs, but it's likely that the bug
affects more Samsung products than just the five series mentioned
above. Further, it should not be harmful to run acpi_ec_clear() on
systems without the bug; it will return immediately after finding no
data waiting.
- Runs acpi_ec_clear() on initialisation (boot), from acpi_ec_add()
- Runs acpi_ec_clear() on wake, from acpi_ec_unblock_transactions()

commit b355cee88e3b1a193f0e9a81db810f6f83ad728b upstream.
ACPI table may export resource entry with 0 length.
But the current code interprets this kind of resource in a wrong way.
It will create a resource structure with
res->end = acpi_resource->start + acpi_resource->len - 1;
This patch fixes a problem on my machine that a platform device fails
to be created because one of its ACPI IO resource entry (start = 0,
end = 0, length = 0) is translated into a generic resource with
start = 0, end = 0xffffffff.

commit c685689fd24d310343ac33942e9a54a974ae9c43 upstream.
We hit one rare case below:
T1 calling disable_irq(), but hanging at synchronize_irq()
always;
The corresponding irq thread is in sleeping state;
And all CPUs are in idle state;
After analysis, we found there is one possible scenerio which
causes T1 is waiting there forever:
CPU0 CPU1
synchronize_irq()
wait_event()
spin_lock()
atomic_dec_and_test(&threads_active)
insert the __wait into queue
spin_unlock()
if(waitqueue_active)
atomic_read(&threads_active)
wake_up()
Here after inserted the __wait into queue on CPU0, and before
test if queue is empty on CPU1, there is no barrier, it maybe
cause it is not visible for CPU1 immediately, although CPU0 has
updated the queue list.
It is similar for CPU0 atomic_read() threads_active also.
So we'd need one smp_mb() before waitqueue_active.that, but removing
the waitqueue_active() check solves it as wel l and it makes
things simple and clear.

commit d86db25e53fa69e3e97f3b55dd82a70689787c5d upstream.
The DELAY_INIT quirk only reduces the frequency of enumeration failures
with the Logitech HD Pro C920 and C930e webcams, but does not quite
eliminate them. We have found that adding a delay of 100ms between the
first and second Get Configuration request makes the device enumerate
perfectly reliable even after several weeks of extensive testing. The
reasons for that are anyone's guess, but since the DELAY_INIT quirk
already delays enumeration by a whole second, wating for another 10th of
that isn't really a big deal for the one other device that uses it, and
it will resolve the problems with these webcams.

commit e0429362ab15c46ea4d64c3f8c9e0933e48a143a upstream.
We've encountered a rare issue when enumerating two Logitech webcams
after a reboot that doesn't power cycle the USB ports. They are spewing
random data (possibly some leftover UVC buffers) on the second
(full-sized) Get Configuration request of the enumeration phase. Since
the data is random this can potentially cause all kinds of odd behavior,
and since it occasionally happens multiple times (after the kernel
issues another reset due to the garbled configuration descriptor), it is
not always recoverable. Set the USB_DELAY_INIT quirk that seems to work
around the issue.

For systems with multiple servers and routed fabric, all
northbridges get assigned to the first server. Fix this by also
using the node reported from the PCI bus. For single-fabric
systems, the northbriges are on PCI bus 0 by definition, which
are on NUMA node 0 by definition, so this is invarient on most
systems.

commit b01d4e68933ec23e43b1046fa35d593cefcf37d1 upstream.
It's an enum, not a #define, you can't use it in asm files.
Introduced in commit 5fa10196bdb5 ("x86: Ignore NMIs that come in during

before pushing out.
My weak excuse is that the x86 tree generally doesn't introduce stupid
things like this (and the ARM pull afterwards doesn't cause me to do a
compile-test either, since I don't cross-compile).

commit 5fa10196bdb5f190f595ebd048490ee52dddea0f upstream.
Don Zickus reports:
A customer generated an external NMI using their iLO to test kdump
worked. Unfortunately, the machine hung. Disabling the nmi_watchdog
made things work.
I speculated the external NMI fired, caused the machine to panic (as
expected) and the perf NMI from the watchdog came in and was latched.
My guess was this somehow caused the hang.
----
It appears that the latched NMI stays latched until the early page
table generation on 64 bits, which causes exceptions to happen which
end in IRET, which re-enable NMI. Therefore, ignore NMIs that come in
during early execution, until we have proper exception handling.

commit 30c219710358c5cca2f8bd2e9e547c6aadf7cf8b upstream.
There are some direct ops->enable in the regulator core driver. This is
a potential issue as the function _regulator_do_enable() handles gpio
regulators and the normal ops->enable calls. These gpio regulators are
simply ignored when ops->enable is called directly.
One possible bug is that boot-on and always-on gpio regulators are not
enabled on registration.
This patch replaces all ops->enable calls by _regulator_do_enable.

commit 621b5060e823301d0cba4cb52a7ee3491922d291 upstream.
When we fork/clone we currently don't copy any of the TM state to the new
thread. This results in a TM bad thing (program check) when the new process is
switched in as the kernel does a tmrechkpt with TEXASR FS not set. Also, since
R1 is from userspace, we trigger the bad kernel stack pointer detection. So we
end up with something like this:
Bad kernel stack pointer 0 at c0000000000404fc
cpu 0x2: Vector: 700 (Program Check) at [c00000003ffefd40]

pid = 0, comm = swapper/2
WARNING: exception is not recoverable, can't continue
The below fixes this by flushing the TM state before we copy the task_struct to
the clone. To do this we go through the tmreclaim patch, which removes the
checkpointed registers from the CPU and transitions the CPU out of TM suspend
mode. Hence we need to call tmrechkpt after to restore the checkpointed state
and the TM mode for the current task.
To make this fail from userspace is simply:

commit 905a5117e79367b7e58ae046d12ca9961f048c89 upstream.
On tha Allwinner A20 SoC, the external interrupts on the pin controller
device are connected to the GIC. Without chained_irq_{enter, exit},
external GPIO interrupts, such as used by mmc core card detect, cause
the system to hang.
This issue was first encountered during my attempt to get out-of-band
interrupts for WiFi on the Cubietruck working. With David's new series
of sunci-mci using mmc slot-gpio for (GPIO interrupt based) card
detection, removing the SD card also causes my Cubietruck to hang. This
problem should extend to all Allwinner A20 based boards.
With this fix, the system no longer hangs when I remove or insert the
SD card. /proc/interrupts show that the interrupt has correctly fired.
However the system still does not detect card removal/insertion. I
believe this is another unrelated issue.

commit 9b745ab897199c2af9f21ca9681ef86d5b971002 upstream.
Lenovo IdeaPad 410Y with ALC282 codec makes loud click noises at boot
and shutdown. Also, it wrongly misdetects the acpi_thinkpad hook.
This patch adds a device-specific fixup for disabling the shutup
callback that is the cause of the click noise and also avoiding the
thinpad_helper calls.

commit c5eda4c1bf6214332c46fb2f4e7c42a85e5e5643 upstream.
The mixer widget (NID 0x20) of AD1884 and AD1984 codecs isn't
connected directly to the actual I/O paths but only via another mixer
widget (NID 0x21). We need a similar fix as we did for AD1882.

commit 3dd77654fb1d7f68b9739f3039bad8dbbc0739f8 upstream.
Actually CS4245 connected to the I2S channel 1 for
capture, not channel 2. Otherwise capturing and
playback does not work for CS4245.

commit 14eedc32a3c0ec9dd70448a73763ee21feae3111 upstream.
Without this, a bo may get created in the cpu-inaccessible vram.
Before the CP engines get setup, all copies are done via cpu memcpy.
This means that the cpu tries to read from inaccessible memory, fails,
and the radeon module proceeds to disable acceleration.
Doing this has no downsides, as the real VRAM size gets set as soon as the
CP engines get init.
This is a candidate for 3.14 fixes.
