#1184464 — [PATCH 3.16.y-ckt 179/185] x86/iosf: Add Kconfig prompt for IOSF_MBI selection

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

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

From: "David E. Box" <david.e.box@linux.intel.com>

commit aa8e4f22ab7773352ba3895597189b8097f2c307 upstream.

Fixes an error in having the iosf build as 'default m'. On X86 SoC's the iosf
sideband is the only way to access information for some registers, as opposed to
through MSR's on other Intel architectures. While selecting IOSF_MBI is
preferred, it does mean carrying extra code on non-SoC architectures. This
exports the selection to the user, allowing those driver writers to compile out
iosf code if it's not being built.

#1184465 — [PATCH 3.16.y-ckt 120/185] drm/i915: fix backlight after resume on 855gm

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

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

From: Jani Nikula <jani.nikula@intel.com>

commit 2059ac3b1304cb6a82f9d90762dea9f556831627 upstream.

Some 855gm models (at least ThinkPad X40) regressed because of

commit b0cd324faed23d10d66ba6ade66579c681feef6f
Author: Jani Nikula <jani.nikula@intel.com>
Date:   Wed Nov 12 16:25:43 2014 +0200

    drm/i915: don't save/restore backlight hist ctl registers

which tried to make our driver more robust by not blindly saving and
restoring registers, but it failed to take into account

commit 0eb96d6ed38430b72897adde58f5477a6b71757a
Author: Jesse Barnes <jbarnes@virtuousgeek.org>
Date:   Wed Oct 14 12:33:41 2009 -0700

    drm/i915: save/restore BLC histogram control reg across suspend/resume

Fix the regression by enabling hist ctl on gen2.

v2: Improved the comment.

v3: Improved the comment, again.

#1184466 — [PATCH 3.16.y-ckt 027/185] ASoC: wm8903: Fix define for WM8903_VMID_RES_250K

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

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

From: Axel Lin <axel.lin@ingics.com>

commit ebb6ad73e645b8f2d098dd3c41d2ff0da4146a02 upstream.

VMID Control 0 BIT[2:1] is VMID Divider Enable and Select

00 = VMID disabled (for OFF mode)
01 = 2 x 50kΩ divider (for normal operation)
10 = 2 x 250kΩ divider (for low power standby)
11 = 2 x 5kΩ divider (for fast start-up)

So WM8903_VMID_RES_250K should be 2 << 1, which is 4.

#1184471 — [PATCH 3.16.y-ckt 183/185] ACPI / PNP: Reserve ACPI resources at the fs_initcall_sync stage

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

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

From: "Rafael J. Wysocki" <rafael.j.wysocki@intel.com>

commit 0294112ee3135fbd15eaa70015af8283642dd970 upstream.

This effectively reverts the following three commits:

 7bc10388ccdd ACPI / resources: free memory on error in add_region_before()
 0f1b414d1907 ACPI / PNP: Avoid conflicting resource reservations
 b9a5e5e18fbf ACPI / init: Fix the ordering of acpi_reserve_resources()

(commit b9a5e5e18fbf introduced regressions some of which, but not
all, were addressed by commit 0f1b414d1907 and commit 7bc10388ccdd
was a fixup on top of the latter) and causes ACPI fixed hardware
resources to be reserved at the fs_initcall_sync stage of system
initialization.

The story is as follows.  First, a boot regression was reported due
to an apparent resource reservation ordering change after a commit
that shouldn't lead to such changes.  Investigation led to the
conclusion that the problem happened because acpi_reserve_resources()
was executed at the device_initcall() stage of system initialization
which wasn't strictly ordered with respect to driver initialization
(and with respect to the initialization of the pcieport driver in
particular), so a random change causing the device initcalls to be
run in a different order might break things.

The response to that was to attempt to run acpi_reserve_resources()
as soon as we knew that ACPI would be in use (commit b9a5e5e18fbf).
However, that turned out to be too early, because it caused resource
reservations made by the PNP system driver to fail on at least one
system and that failure was addressed by commit 0f1b414d1907.

That fix still turned out to be insufficient, though, because
calling acpi_reserve_resources() before the fs_initcall stage of
system initialization caused a boot regression to happen on the
eCAFE EC-800-H20G/S netbook.  That meant that we only could call
acpi_reserve_resources() at the fs_initcall initialization stage
or later, but then we might just as well call it after the PNP
initalization in which case commit 0f1b414d1907 wouldn't be
necessary any more.

For this reason, the changes made by commit 0f1b414d1907 are reverted
(along with a memory leak fixup on top of that commit), the changes
made by commit b9a5e5e18fbf that went too far are reverted too and
acpi_reserve_resources() is changed into fs_initcall_sync, which
will cause it to be executed after the PNP subsystem initialization
(which is an fs_initcall) and before device initcalls (including
the pcieport driver initialization) which should avoid the initial
issue.

#1184473 — [PATCH 3.16.y-ckt 168/185] sched/fair: Prevent throttling in early pick_next_task_fair()

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

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

From: Ben Segall <bsegall@google.com>

commit 54d27365cae88fbcc853b391dcd561e71acb81fa upstream.

The optimized task selection logic optimistically selects a new task
to run without first doing a full put_prev_task(). This is so that we
can avoid a put/set on the common ancestors of the old and new task.

Similarly, we should only call check_cfs_rq_runtime() to throttle
eligible groups if they're part of the common ancestry, otherwise it
is possible to end up with no eligible task in the simple task
selection.

Imagine:
		/root
	/prev		/next
	/A		/B

If our optimistic selection ends up throttling /next, we goto simple
and our put_prev_task() ends up throttling /prev, after which we're
going to bug out in set_next_entity() because there aren't any tasks
left.

Avoid this scenario by only throttling common ancestors.

#1184474 — [PATCH 3.16.y-ckt 185/185] lz4: fix system halt at boot kernel on x86_64

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

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

From: Krzysztof Kolasa <kkolasa@winsoft.pl>

commit 99b7e93c95c78952724a9783de6c78def8fbfc3f upstream.

Sometimes, on x86_64, decompression fails with the following
error:

Decompressing Linux...

Decoding failed

 -- System halted

This condition is not needed for a 64bit kernel(from commit d5e7caf):

if( ... ||
    (op + COPYLENGTH) > oend)
    goto _output_error

macro LZ4_SECURE_COPY() tests op and does not copy any data
when op exceeds the value.

added by analogy to lz4_uncompress_unknownoutputsize(...)

#1184475 — [PATCH 3.16.y-ckt 150/185] clk: ti: dra7-atl-clock: Fix possible ERR_PTR dereference

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

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

From: Krzysztof Kozlowski <k.kozlowski@samsung.com>

commit e0cdcda508f110b7ec190dc7c5eb2869ba73a535 upstream.

of_clk_get_from_provider() returns ERR_PTR on failure. The
dra7-atl-clock driver was not checking its return value and
immediately used it in __clk_get_hw().  __clk_get_hw()
dereferences supplied clock, if it is not NULL, so in that case
it would dereference an ERR_PTR.

commit 2222ce0fbbcc4ebfa9995c8d23d72c8239ad712c upstream.

Failure return from dlpar_configure_connector when dlpar adding cpus

#1184478 — [PATCH 3.16.y-ckt 162/185] mac80211: prevent possible crypto tx tailroom corruption

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

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

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

commit ab499db80fcf07c18e4053f91a619500f663e90e upstream.

There was a possible race between
ieee80211_reconfig() and
ieee80211_delayed_tailroom_dec(). This could
result in inability to transmit data if driver
crashed during roaming or rekeying and subsequent
skbs with insufficient tailroom appeared.

This race was probably never seen in the wild
because a device driver would have to crash AND
recover within 0.5s which is very unlikely.

I was able to prove this race exists after
changing the delay to 10s locally and crashing
ath10k via debugfs immediately after GTK
rekeying. In case of ath10k the counter went below
0. This was harmless but other drivers which
actually require tailroom (e.g. for WEP ICV or
MMIC) could end up with the counter at 0 instead
of >0 and introduce insufficient skb tailroom
failures because mac80211 would not resize skbs
appropriately anymore.

If we'd already sent a request and decide to abort it, we *must*
issue TFLUSH properly and not just blindly reuse the tag, or
we'll get seriously screwed when response eventually arrives
and we confuse it for response to later request that had reused
the same tag.

#1184480 — [PATCH 3.16.y-ckt 159/185] ath9k_htc: memory corruption calling set_bit()

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

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

From: Dan Carpenter <dan.carpenter@oracle.com>

commit 191f1aeeb93bb58e56f4d1868294ae22f3f67d4e upstream.

In d8a2c51cdcae ('ath9k_htc: Use atomic operations for op_flags') we
changed things like this:

-	if (priv->op_flags & OP_TSF_RESET) {
+	if (test_bit(OP_TSF_RESET, &priv->op_flags)) {

The problem is that test_bit() takes a bit number and not a mask.  It
means that when we do:

	set_bit(OP_TSF_RESET, &priv->op_flags);

Then it sets the (1 << 6) bit instead of the 6 bit so we are setting a
bit which is past the end of the unsigned long.

The USB phy should initialize with power-off, and will be powered on

Having this pm_runtime_get_sync() during probe causes the phy to
*always* be powered on.
Removing it returns to sensible power management.

#1184482 — [PATCH 3.16.y-ckt 156/185] tty: remove platform_sysrq_reset_seq

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

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

From: Arnd Bergmann <arnd@arndb.de>

commit abab381feea7e61a0b5125504aa955cf339676ca upstream.

The platform_sysrq_reset_seq code was intended as a way for an embedded
platform to provide its own sysrq sequence at compile time. After over
two years, nobody has started using it in an upstream kernel, and
the platforms that were interested in it have moved on to devicetree,
which can be used to configure the sequence without requiring kernel
changes. The method is also incompatible with the way that most
architectures build support for multiple platforms into a single
kernel.

Now the code is producing warnings when built with gcc-5.1:

drivers/tty/sysrq.c: In function 'sysrq_init':
drivers/tty/sysrq.c:959:33: warning: array subscript is above array bounds [-Warray-bounds]
   key = platform_sysrq_reset_seq[i];

We could fix this, but it seems unlikely that it will ever be used,
so let's just remove the code instead. We still have the option to
pass the sequence either in DT, using the kernel command line,
or using the /sys/module/sysrq/parameters/reset_seq file.

#1184484 — [PATCH 3.16.y-ckt 152/185] HID: rmi: fix some harmless BIT() mistakes

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

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

From: Dan Carpenter <dan.carpenter@oracle.com>

commit af43c4086cf24c3eb74a968195351163750c82b6 upstream.

These defines are used like this:

	if (!(test_bit(RMI_STARTED, &hdata->flags)))

So the intent was to use bits 0, 1 and 2 but because of the extra BIT()
shifts we're actually using 1, 2 and 4.  It's harmless because it's done
consistently but static checkers will complain.

#1184485 — [PATCH 3.16.y-ckt 163/185] cfg80211: ignore netif running state when changing iftype

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

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

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

commit 6cbfb1bb66e4e85da5db78e8ff429a85bd84ce64 upstream.

It was possible for mac80211 to be coerced into an
unexpected flow causing sdata union to become
corrupted. Station pointer was put into
sdata->u.vlan.sta memory location while it was
really master AP's sdata->u.ap.next_beacon. This
led to station entry being later freed as
next_beacon before __sta_info_flush() in
ieee80211_stop_ap() and a subsequent invalid
pointer dereference crash.

The problem was that ieee80211_ptr->use_4addr
wasn't cleared on interface type changes.

This could be reproduced with the following steps:

 # host A and host B have just booted; no
 # wpa_s/hostapd running; all vifs are down
 host A> iw wlan0 set type station
 host A> iw wlan0 set 4addr on
 host A> printf 'interface=wlan0\nssid=4addrcrash\nchannel=1\nwds_sta=1' > /tmp/hconf
 host A> hostapd -B /tmp/conf
 host B> iw wlan0 set 4addr on
 host B> ifconfig wlan0 up
 host B> iw wlan0 connect -w hostAssid
 host A> pkill hostapd
 # host A crashed:

("cfg80211: check iface combinations only when
iface is running") as far as functionality is
considered because b6a550156bc ("cfg80211/mac80211:
move more combination checks to mac80211") moved
the logic somewhere else already.

#1184488 — [PATCH 3.16.y-ckt 176/185] mm/hugetlb: introduce minimum hugepage order

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

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

From: Naoya Horiguchi <n-horiguchi@ah.jp.nec.com>

commit 641844f5616d7c6597309f560838f996466d7aac upstream.

Currently the initial value of order in dissolve_free_huge_page is 64 or
32, which leads to the following warning in static checker:

  mm/hugetlb.c:1203 dissolve_free_huge_pages()
  warn: potential right shift more than type allows '9,18,64'

This is a potential risk of infinite loop, because 1 << order (== 0) is used
in for-loop like this:

  for (pfn =3D start_pfn; pfn < end_pfn; pfn +=3D 1 << order)
      ...

So this patch fixes it by using global minimum_order calculated at boot time.

#1184491 — [PATCH 3.16.y-ckt 160/185] rndis_wlan: harmless issue calling set_bit()

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

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

From: Dan Carpenter <dan.carpenter@oracle.com>

commit e3958e9d60b4570fff709f397ef5c6b8483f40f7 upstream.

These are used like:

	set_bit(WORK_LINK_UP, &priv->work_pending);

The problem is that set_bit() takes the actual bit number and not a mask
so static checkers get upset.  It doesn't affect run time because we do
it consistently, but we may as well clean it up.

#1184492 — [PATCH 3.16.y-ckt 174/185] watchdog: omap: assert the counter being stopped before reprogramming

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

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

From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= <u.kleine-koenig@pengutronix.de>

commit 530c11d432727c697629ad5f9d00ee8e2864d453 upstream.

The omap watchdog has the annoying behaviour that writes to most
registers don't have any effect when the watchdog is already running.
Quoting the AM335x reference manual:

	To modify the timer counter value (the WDT_WCRR register),
	prescaler ratio (the WDT_WCLR[4:2] PTV bit field), delay
	configuration value (the WDT_WDLY[31:0] DLY_VALUE bit field), or
	the load value (the WDT_WLDR[31:0] TIMER_LOAD bit field), the
	watchdog timer must be disabled by using the start/stop sequence
	(the WDT_WSPR register).

Currently the timer is stopped in the .probe callback but still there
are possibilities that yield to a situation where omap_wdt_start is
entered with the timer running (e.g. when /dev/watchdog is closed
without stopping and then reopened). In such a case programming the
timeout silently fails!

To circumvent this stop the timer before reprogramming.

Assuming one of the first things the watchdog user does is setting the
timeout explicitly nothing too bad should happen because this explicit
setting works fine.

#1184493 — [PATCH 3.16.y-ckt 158/185] IB/mlx4: Convert slave port before building address-handle

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

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

From: Or Gerlitz <ogerlitz@mellanox.com>

commit 430910b1b93292d3a724c91123bb15bd32df1b5b upstream.

When multiplexling a MAD sent from VF, we should convert the port used
by the guest to send the packet to the actual physical port which will be
used to transmit the packet, before building the relevant address-handle (AH).

This is needed under VPI for single ported VFs, since the code that builds
the AH (mlx4_ib_query_ah()) makes decisions based on the input port. If we
use the port number provided by the guest, it might have different protocol
vs. the one this packat has to go from, and hence the result could be wrong.

So far, the conversion was done after the AH was built and it worked for
single ported Eth VFs which were not enabled under VPI. When adding support
for single ported IB VFs and VPI, we hit that.
