[PATCH 3.14 01/38] ASoC: sgtl5000: remove useless register write clearing CHRGPUMP_POWERUP

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Eric Nelson <eric.nelson@boundarydevices.com>

commit c7d910b87d3c8e9fcf4077089ca4327c12eee099 upstream.

The SGTL5000_CHIP_ANA_POWER register is cached. Update the cached
value instead of writing it directly.

Patch inspired by Russell King's more colorful remarks in this
patch:

[PATCH 3.14 02/38] ASoC: pcm1681: Fix wrong value references for boolean kctl

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <tiwai@suse.de>

commit d7f58db49d9ad92bdb12d21fdc2308b76bc2ed38 upstream.

The correct values referred by a boolean control are
value.integer.value[], not value.enumerated.item[].
The former is long while the latter is int, so it's even incompatible
on 64bit architectures.

value.integer.value[], not value.enumerated.item[].
The former is long while the latter is int, so it's even incompatible

From: Yongbae Park <yongbae2@gmail.com>

commit 1096be084ac59927158ce80ff1d31c33eed0e565 upstream.

The interrupt is enabled before the handler is set. Even this bug
did not appear, it is potentially dangerous as it can lead to a
NULL pointer dereference.

Fix the error by enabling the interrupt after
clockevents_config_and_register() is called.

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lars-Peter Clausen <lars@metafoo.de>

commit 328f494d95aac8bd4896aea2328bc281053bcb71 upstream.

When inserting a new register into a block at the lower end the present
bitmap is currently shifted into the wrong direction. The effect of this is
that the bitmap becomes corrupted and registers which are present might be
reported as not present and vice versa.

Fix this by shifting left rather than right.

[PATCH 3.14 18/38] tcm_qla2xxx: Fix incorrect use of __transport_register_session

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bart Van Assche <bart.vanassche@sandisk.com>

commit 75c3d0bf9caebb502e96683b2bc37f9692437e68 upstream.

This patch fixes the incorrect use of __transport_register_session()
in tcm_qla2xxx_check_initiator_node_acl() code, that does not perform
explicit se_tpg->session_lock when accessing se_tpg->tpg_sess_list
to add new se_sess nodes.

Given that tcm_qla2xxx_check_initiator_node_acl() is not called with
qla_hw->hardware_lock held for all accesses of ->tpg_sess_list, the
code should be using transport_register_session() instead.

From: Johannes Berg <johannes.berg@intel.com>

commit 496fcc294daab18799e190c0264863d653588d1f upstream.

As HT/VHT depend heavily on QoS/WMM, it's not a good idea to
let userspace add clients that have HT/VHT but not QoS/WMM.
Since it does so in certain cases we've observed (client is
using HT IEs but not QoS/WMM) just ignore the HT/VHT info at
this point and don't pass it down to the drivers which might
unconditionally use it.

[PATCH 3.14 20/38] mac80211: disable u-APSD queues by default

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Michal Kazior <michal.kazior@tieto.com>

commit aa75ebc275b2a91b193654a177daf900ad6703f0 upstream.

Some APs experience problems when working with
U-APSD. Decreasing the probability of that
happening by using legacy mode for all ACs but VO
isn't enough.

Cisco 4410N originally forced us to enable VO by
default only because it treated non-VO ACs as
legacy.

However some APs (notably Netgear R7000) silently
reclassify packets to different ACs. Since u-APSD
ACs require trigger frames for frame retrieval
clients would never see some frames (e.g. ARP
responses) or would fetch them accidentally after
a long time.

It makes little sense to enable u-APSD queues by
default because it needs userspace applications to
be aware of it to actually take advantage of the
possible additional powersavings. Implicitly
depending on driver autotrigger frame support
doesn't make much sense.

[PATCH 3.14 23/38] phy: Find the right match in devm_phy_destroy()

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Thierry Reding <treding@nvidia.com>

commit 2f1bce487cd0a02623cff3d877940f9a2026341c upstream.

devm_phy_create() stores the pointer to the new PHY at the address
returned by devres_alloc(). The res parameter passed to devm_phy_match()
is therefore the location where the pointer to the PHY is stored, hence
it needs to be dereferenced before comparing to the match data in order
to find the correct match.

[PATCH 3.14 24/38] of/irq: Fix of_irq_parse_one() returned error codes

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

commit d7c146053dd195b90c79b9b8131431f44541d015 upstream.

The error code paths that require cleanup use a goto to jump to the
cleanup code and return an error code. However, the error code variable
res, which is initialized to -EINVAL when declared, is then overwritten
with the return value of of_parse_phandle_with_args(), and reused as the
return code from of_irq_parse_one(). This leads to an undetermined error
being returned instead of the expected -EINVAL value. Fix it.

[PATCH 3.14 25/38] perf: Fix irq_work tail recursion

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Peter Zijlstra <peterz@infradead.org>

commit d525211f9d1be8b523ec7633f080f2116f5ea536 upstream.

Vince reported a watchdog lockup like:

	[<ffffffff8115e114>] perf_tp_event+0xc4/0x210
	[<ffffffff810b4f8a>] perf_trace_lock+0x12a/0x160

	[<ffffffff811f71ce>] send_sigio+0xae/0x100
	[<ffffffff811f72b7>] kill_fasync+0x97/0xf0
	[<ffffffff8115d0b4>] perf_event_wakeup+0xd4/0xf0
	[<ffffffff8115d103>] perf_pending_event+0x33/0x60
	[<ffffffff8114e3fc>] irq_work_run_list+0x4c/0x80
	[<ffffffff8114e448>] irq_work_run+0x18/0x40
	[<ffffffff810196af>] smp_trace_irq_work_interrupt+0x3f/0xc0
	[<ffffffff816c99bd>] trace_irq_work_interrupt+0x6d/0x80

Which is caused by an irq_work generating new irq_work and therefore
not allowing forward progress.

This happens because processing the perf irq_work triggers another
perf event (tracepoint stuff) which in turn generates an irq_work ad
infinitum.

Avoid this by raising the recursion counter in the irq_work -- which
effectively disables all software events (including tracepoints) from
actually triggering again.

Since it's possible for the discard and write same queue limits to
change while the upper level command is being sliced and diced, fix up
both of them (a) to reject IO if the special command is unsupported at
the start of the function and (b) read the limits once and let the
commands error out on their own if the status happens to change.

[PATCH 3.14 32/38] hfsplus: fix B-tree corruption after insertion at position 0

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sergei Antonov <saproj@gmail.com>

commit 98cf21c61a7f5419d82f847c4d77bf6e96a76f5f upstream.

Fix B-tree corruption when a new record is inserted at position 0 in the
node in hfs_brec_insert().  In this case a hfs_brec_update_parent() is
called to update the parent index node (if exists) and it is passed
hfs_find_data with a search_key containing a newly inserted key instead
of the key to be updated.  This results in an inconsistent index node.
The bug reproduces on my machine after an extents overflow record for
the catalog file (CNID=4) is inserted into the extents overflow B-tree.
Because of a low (reserved) value of CNID=4, it has to become the first
record in the first leaf node.

The resulting first leaf node is correct:

  ----------------------------------------------------
  | key0.CNID=4 | key1.CNID=123 | key2.CNID=456, ... |
  ----------------------------------------------------

But the parent index key0 still contains the previous key CNID=123:

  -----------------------
  | key0.CNID=123 | ... |
  -----------------------

A change in hfs_brec_insert() makes hfs_brec_update_parent() work
correctly by preventing it from getting fd->record=-1 value from
__hfs_brec_find().

Along the way, I removed duplicate code with unification of the if
condition.  The resulting code is equivalent to the original code
because node is never 0.

Also hfs_brec_update_parent() will now return an error after getting a
negative fd->record value.  However, the return value of
hfs_brec_update_parent() is not checked anywhere in the file and I'm
leaving it unchanged by this patch.  brec.c lacks error checking after
some other calls too, but this issue is of less importance than the one
being fixed by this patch.

[PATCH 3.14 33/38] powerpc/book3s: Fix the MCE code to use CONFIG_KVM_BOOK3S_64_HANDLER

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mahesh Salgaonkar <mahesh@linux.vnet.ibm.com>

commit 44d5f6f5901e996744858c175baee320ccf1eda3 upstream.

commit id 2ba9f0d has changed CONFIG_KVM_BOOK3S_64_HV to tristate to allow
HV/PR bits to be built as modules. But the MCE code still depends on
CONFIG_KVM_BOOK3S_64_HV which is wrong. When user selects
CONFIG_KVM_BOOK3S_64_HV=m to build HV/PR bits as a separate module the
relevant MCE code gets excluded.

This patch fixes the MCE code to use CONFIG_KVM_BOOK3S_64_HANDLER. This
makes sure that the relevant MCE code is included when HV/PR bits
are built as a separate modules.

[PATCH 3.14 35/38] powerpc/pseries: Little endian fixes for post mobility device tree update

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tyrel Datwyler <tyreld@linux.vnet.ibm.com>

commit f6ff04149637723261aa4738958b0098b929ee9e upstream.

We currently use the device tree update code in the kernel after resuming
from a suspend operation to re-sync the kernels view of the device tree with
that of the hypervisor. The code as it stands is not endian safe as it relies
on parsing buffers returned by RTAS calls that thusly contains data in big
endian format.

This patch annotates variables and structure members with __be types as well
as performing necessary byte swaps to cpu endian for data that needs to be
parsed.

[PATCH 3.14 36/38] powerpc/mpc85xx: Add ranges to etsec2 nodes

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Scott Wood <scottwood@freescale.com>

commit bb344ca5b90df62b1a3b7a35c6a9d00b306a170d upstream.

Commit 746c9e9f92dd "of/base: Fix PowerPC address parsing hack" limited
the applicability of the workaround whereby a missing ranges is treated
as an empty ranges.  This workaround was hiding a bug in the etsec2
device tree nodes, which have children with reg, but did not have
ranges.

[PATCH 3.14 37/38] net: ethernet: pcnet32: Setup the SRAM and NOUFLO on Am79C97{3, 5}

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Markos Chandras <markos.chandras@imgtec.com>

commit 87f966d97b89774162df04d2106c6350c8fe4cb3 upstream.

On a MIPS Malta board, tons of fifo underflow errors have been observed
when using u-boot as bootloader instead of YAMON. The reason for that
is that YAMON used to set the pcnet device to SRAM mode but u-boot does
not. As a result, the default Tx threshold (64 bytes) is now too small to
keep the fifo relatively used and it can result to Tx fifo underflow errors.
As a result of which, it's best to setup the SRAM on supported controllers
so we can always use the NOUFLO bit.

[PATCH 3.14 38/38] mfd: kempld-core: Fix callback return value check

From: Ameya Palande <2ameya@gmail.com>

commit c8648508ebfc597058d2cd00b6c539110264a167 upstream.

On success, callback function returns 0. So invert the if condition
check so that we can break out of loop.
