6bab4a8a18 clockevent: sun4i: Fix race condition in the probe code
The interrupts were activated and the handler registered before the clockevent
was registered in the probe function.

The interrupt handler, however, was making the assumption that the clockevent
device was registered.

That could cause a null pointer dereference if the timer interrupt was firing
during this narrow window.

Fix that by moving the clockevent registration before the interrupt is enabled.

280ba51d60 mac80211: minstrel_ht: fix a crash in rate sorting
The commit 5935839ad7
"mac80211: improve minstrel_ht rate sorting by throughput & probability"

introduced a crash on rate sorting that occurs when the rate added to
the sorting array is faster than all the previous rates. Due to an
off-by-one error, it reads the rate index from tp_list[-1], which
contains uninitialized stack garbage, and then uses the resulting index
for accessing the group rate stats, leading to a crash if the garbage
value is big enough.

80646733f1 can: m_can: update to support CAN FD features
Bosch M_CAN is CAN FD capable device. This patch implements the CAN
FD features include up to 64 bytes payload and bitrate switch function.
1) Change the Rx FIFO and Tx Buffer to 64 bytes for support CAN FD
   up to 64 bytes payload. It's backward compatible with old 8 bytes
   normal CAN frame.
2) Allocate can frame or canfd frame based on EDL bit
3) Bitrate Switch function is disabled by default and will be enabled
   according to CANFD_BRS bit in cf->flags.

7660f63307 can: m_can: add missing delay after setting CCCR_INIT bit
The spec mentions there may be a delay until the value written to INIT can be
read back due to the synchronization mechanism between the two clock domains.
But it does not indicate the exact clock cycles needed. The 5us delay is a
test value and seems ok.

Without the delay, CCCR.CCE bit may fail to be set and then the initialization
fail sometimes when do repeatly up and down.

962845da54 can: m_can: add missing message RAM initialization
The M_CAN message RAM is usually equipped with a parity or ECC functionality.
But RAM cells suffer a hardware reset and can therefore hold arbitrary content
at startup - including parity and/or ECC bits.

To prevent the M_CAN controller detecting checksum errors when reading
potentially uninitialized TX message RAM content to transmit CAN frames the TX
message RAM has to be written with (any kind of) initial data.

746c9e9f92 of/base: Fix PowerPC address parsing hack
We have a historical hack that treats missing ranges properties as the
equivalent of an empty one. This is needed for ancient PowerMac "bad"
device-trees, and shouldn't be enabled for any other PowerPC platform,
otherwise we get some nasty layout of devices in sysfs or even
duplication when a set of otherwise identically named devices is
created multiple times under a different parent node with no ranges
property.

This fix is needed for the PowerNV i2c busses to be exposed properly
and will fix a number of other embedded cases.

ab74d00a39 of: Fix crash if an earlycon driver is not found
__earlycon_of_table_sentinel.compatible is a char[128], not a pointer, so
it will never be NULL.  Checking it against NULL causes the match loop to
run past the end of the array, and eventually match a bogus entry, under
the following conditions:

 - Kernel command line specifies "earlycon" with no parameters
 - DT has a stdout-path pointing to a UART node
 - The UART driver doesn't use OF_EARLYCON_DECLARE (or maybe the console
   driver is compiled out)

Fix this by checking to see if match->compatible is a non-empty string.

fb86b97300 x86, microcode: Update BSPs microcode on resume
In the situation when we apply early microcode but do *not* apply late
microcode, we fail to update the BSP's microcode on resume because we
haven't initialized the uci->mc microcode pointer. So, in order to
alleviate that, we go and dig out the stashed microcode patch during
early boot. It is basically the same thing that is done on the APs early
during boot so do that too here.

6676f3081f ALSA: hda - fix the mic mute led problem for Latitude E5550
The microphone mute led on the Latitude E5550 can't work. We need to
apply DELL_WMI_MIC_MUTE_LED quirk to this machine.

The machine uses alc293 codec and already applied the quirk
ALC293_FIXUP_DELL1_MIC_NO_PRESENCE through pin_fixup_tbl[].

Here we just let DELL_WMI_MIC_MUTE_LED be chained to
ALC269_FIXUP_HEADSET_MODE, then the machine will have these
quirks ALC293_FIXUP_DELL1_MIC_NO_PRESENCE-->
ALC269_FIXUP_HEADSET_MODE-->ALC255_FIXUP_DELL_WMI_MIC_MUTE_LED.

4a83d42ae2 ALSA: hda - move DELL_WMI_MIC_MUTE_LED to the tail in the quirk chain
We have one more Dell machine needs DELL_WMI_MIC_MUTE_LED quirk, but
the machine uses alc293 instead of alc255. So if
DELL_WMI_MIC_MUTE_LED still chain ALC255_FIXUP_DELL1_MIC_NO_PRESENCE,
the machine can't use this quirk.

To change this situation, let the DELL_WMI_MIC_MUTE_LED to be a
standalone quirk, and let other quirks chain it.

After this change, this quirk can be chained to any existing quirks,
and as a result, it is possible that this quirk is applied to
a non-Dell machine or a Dell machine without mic mute led on it, but
it is still safe since alc_fixup_dell_wmi() will return an error in
these situations.

And remove the quirk for machine with subsystem id 0x6010 and 0x601f,
these two machines will fall back to the quirk
ALC255_FIXUP_DELL1_MIC_NO_PRESENCE-->ALC255_FIXUP_HEADSET_MODE-->
ALC255_FIXUP_DELL_WMI_MIC_MUTE_LED through pin_fixup_tbl[].

The commit 543c043cba ("powerpc/fsl_msi: change the irq handler from

normal. Since cascade handler must run in hard interrupt context, this
will cause kernel panic if we force threading of all the interrupt
handler via kernel command parameter 'threadirqs'. So mark the irq
handler IRQF_NO_THREAD explicitly.

 One is a fix for a race in DPCM which is unfortuantely a rather large

 hence more detailed testing so I'm relatively happy.
 
 The other is a fix for non-DT machine driver matching following some of
 the componentization work which is much more focused.
 
 Both have had a while to cook in -next.

daad166028 ath9k: fix regression in bssidmask calculation
The commit that went into 3.17:

    ath9k: Summarize hw state per channel context

    Group and set hw state (opmode, primary_sta, beacon conf) per
    channel context instead of whole list of vifs. This would allow
    each channel context to run in different mode (STA/AP).

    Signed-off-by: Rajkumar Manoharan <rmanohar@qti.qualcomm.com>
    Signed-off-by: John W. Linville <linville@tuxdriver.com>

broke multi-vif configuration due to not properly calculating
the bssid mask.

The test case that caught this was:

 create wlan0 and sta0-4 (6 total), not sure how much that matters.
 associate all 6 (works fine)
 disconnect 5 of them, leaving sta0 up
 Start trying to bring up the other 5 one at a time.  It will
 fail, with iw events looking like this (in these logs, several
 sta are trying to come up, but symptom is the same with just one)

The patch causing the regression made quite a few changes, but
the part I think caused this particular problem was not
recalculating the bssid mask when adding and removing interfaces.

Re-adding those calls fixes my test case.  Fix bad comment
as well.

f0b4eeced5 bridge: fix netfilter/NF_BR_LOCAL_OUT for own, locally generated queries
Ebtables on the OUTPUT chain (NF_BR_LOCAL_OUT) would not work as expected
for both locally generated IGMP and MLD queries. The IP header specific
filter options are off by 14 Bytes for netfilter (actual output on
interfaces is fine).

NF_HOOK() expects the skb->data to point to the IP header, not the
ethernet one (while dev_queue_xmit() does not). Luckily there is an
br_dev_queue_push_xmit() helper function already - let's just use that.

Introduced by eb1d164143
("bridge: Add core IGMP snooping support")

Ebtables example:

$ ebtables -I OUTPUT -p IPv6 -o eth1 --logical-out br0 \
	--log --log-level 6 --log-ip6 --log-prefix="~EBT: " -j DROP

before (broken):

~EBT:  IN= OUT=eth1 MAC source = 02:04:64:a4:39:c2 \
	MAC dest = 33:33:00:00:00:01 proto = 0x86dd IPv6 \
	SRC=64a4:39c2:86dd:6000:0000:0020:0001:fe80 IPv6 \
	DST=0000:0000:0000:0004:64ff:fea4:39c2:ff02, \
	IPv6 priority=0x3, Next Header=2

after (working):

~EBT:  IN= OUT=eth1 MAC source = 02:04:64:a4:39:c2 \
	MAC dest = 33:33:00:00:00:01 proto = 0x86dd IPv6 \
