[ Upstream commit 2aacace6dbbb6b6ce4e177e6c7ea901f389c0472 ]
In attach_node_and_children memory is allocated for full_name via
kasprintf. If the condition of the 1st if is not met the function
returns early without freeing the memory. Add a kfree() to fix that.
This has been detected with kmemleak:
Link: https://bugzilla.kernel.org/show_bug.cgi?id=205327
It looks like the leak was introduced by this commit:

[ Upstream commit a7ede3d16808b8f3915c8572d783530a82b2f027 ]
With commit 6ce220dd2f8ea71d6afc29b9a7524c12e39f374a ("raid5: don't set
STRIPE_HANDLE to stripe which is in batch list"), we don't want to set
STRIPE_HANDLE flag for sh which is already in batch list.
However, the stripe which is the head of batch list should set this flag,
otherwise panic could happen inside init_stripe at BUG_ON(sh->batch_head),
it is reproducible with raid5 on top of nvdimm devices per Xiao oberserved.
Thanks for Xiao's effort to verify the change.

[ Upstream commit 2727315df3f5ffbebcb174eed3153944a858b66f ]
The Terra Pad 1061 has the usual micro-USB-B id-pin handler, but instead
of controlling the actual micro-USB-B it turns the 5V boost for the
tablet's USB-A connector and its keyboard-cover connector off.
The actual micro-USB-B connector on the tablet is wired for charging only,
and its id pin is *not* connected to the GPIO which is used for the
(broken) id-pin event handler in the DSDT.
While at it not only add a comment why the Terra Pad 1061 is on the
blacklist, but also fix the missing comment for the Minix Neo Z83-4 entry.

commit ff34f3cce278a0982a7b66b1afaed6295141b1fc upstream.
The 'a0' member of 'struct arm_smccc_res' is declared as 'unsigned long',
however the Qualcomm SCM firmware interface driver expects to receive
negative error codes via this field, so ensure that it's cast to 'long'
before comparing to see if it is less than 0.

[ Upstream commit 08d80e4cd27ba19f9bee9e5f788f9a9fc440a22f ]
On SMP platform, when continuously running wifi up/down, the napi
poll can be scheduled during chip reset, which will call
ath10k_pci_has_fw_crashed() to check the fw status. But in the reset
period, the value from FW_INDICATOR_ADDRESS register will return
0xdeadbeef, which also be treated as fw crash. Fix the issue by
moving chip reset after napi disabled.

[ Upstream commit ee1c71a8e1456ab53fe667281d855849edf26a4d ]
If the system has other devices being registered in the component
framework, the compare function will be called with a device that
doesn't belong to vimc.
This device is not necessarily a platform_device, nor have a
platform_data (which causes a NULL pointer dereference error) and if it
does have a pdata, it is not necessarily type of struct vimc_platform_data.
So casting to any of these types is wrong.
Instead of expecting a given pdev with a given pdata, just expect for
the device it self. vimc-core is the one who creates them, we know in
advance exactly which object to expect in the match.

[ Upstream commit 83d5782681cc12b3d485a83cb34c46b2445f510c ]
The driver tries to periodically refresh neighbours that are used to
reach nexthops. This is done by periodically calling neigh_event_send().
However, if the neighbour becomes dead, there is nothing we can do to
return it to a connected state and the above function call is basically
a NOP.
This results in the nexthop never being written to the device's
adjacency table and therefore never used to forward packets.
Fix this by dropping our reference from the dead neighbour and
associating the nexthop with a new neigbhour which we will try to
refresh.

[ Upstream commit 100843f176109af94600e500da0428e21030ca7f ]
While v2.6.26 commit b75db73159cc ("[SCSI] zfcp: Add qtcb dump to hba debug
trace") is right that we don't want to flood the (payload) trace ring
buffer, we don't trace successful FCP command responses by default. So we
can include the channel log for problem determination with failed responses
of any FSF request type.
Fixes: b75db73159cc ("[SCSI] zfcp: Add qtcb dump to hba debug trace")

commit 998174042da229e2cf5841f574aba4a743e69650 upstream.
Going through the uses of timeval in the user space API,
I noticed two bugs in ppdev that were introduced in the y2038
conversion:
* The range check was accidentally moved from ppsettime to
ppgettime
* On sparc64, the microseconds are in the other half of the
64-bit word.
Fix both, and mark the fix for stable backports.

pandora_wl1251_init_card
commit f6498b922e57aecbe3b7fa30a308d9d586c0c369 upstream.
Pandora_wl1251_init_card was used to do special pdata based
setup of the sdio mmc interface. This does no longer work with
v4.7 and later. A fix requires a device tree based mmc3 setup.
Therefore we move the special setup to omap_hsmmc.c instead
of calling some pdata supplied init_card function.
The new code checks for a DT child node compatible to wl1251
so it will not affect other MMC3 use cases.
Generally, this code was and still is a hack and should be
moved to mmc core to e.g. read such properties from optional
DT child nodes.

commit b9ea0bae260f6aae546db224daa6ac1bd9d94b91 upstream.
Certain ACPI-enumerated devices represented as platform devices in
Linux, like fans, require special low-level power management handling
implemented by their drivers that is not in agreement with the ACPI
PM domain behavior. That leads to problems with managing ACPI fans
during system-wide suspend and resume.
For this reason, make acpi_dev_pm_attach() skip the affected devices
by adding a list of device IDs to avoid to it and putting the IDs of
the affected devices into that list.

In i2c_acpi_remove_space_handler(), a leak occurs whenever the
"data" parameter is initialized to 0 before being passed to
acpi_bus_get_private_data().
This is because the NULL pointer check in acpi_bus_get_private_data()
(condition->if(!*data)) returns EINVAL and, in consequence, memory is
never freed in i2c_acpi_remove_space_handler().
Fix the NULL pointer check in acpi_bus_get_private_data() to follow
the analogous check in acpi_get_data_full().

commit 833a426cc471b6088011b3d67f1dc4e147614647 upstream.
acpi_os_map_cleanup checks map->refcount outside of acpi_ioremap_lock
before freeing the map. This creates a race condition the can result
in the map being freed more than once.
A panic can be caused by running

do
for ((j=0; j<100000; j++))
do

to 0 does the freeing.

commit db0d32d84031188443e25edbd50a71a6e7ac5d1d upstream.
The following build warning occurred on powerpc 64-bit builds:
drivers/cpufreq/powernv-cpufreq.c: In function 'init_chip_info':
drivers/cpufreq/powernv-cpufreq.c:1070:1: warning: the frame size of
1040 bytes is larger than 1024 bytes [-Wframe-larger-than=]
This is with a cross-compiler based on gcc 8.1.0, which I got from:
https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/8.1.0/
The warning is due to putting 1024 bytes on the stack:
unsigned int chip[256];
...and it's also undesirable to have a hard limit on the number of
CPUs here.
Fix both problems by dynamically allocating based on num_possible_cpus,
as recommended by Michael Ellerman.

commit e7fad909b68aa37470d9f2d2731b5bec355ee5d6 upstream.
Commit 75d66ffb48efb3 added backing device health checks and as a part
of these checks, check_events() block ops template call is invoked in
dm-zoned mapping path as well as in reclaim and flush path. Calling
check_events() with ATA or SCSI backing devices introduces a blocking
scsi_test_unit_ready() call being made in sd_check_events(). Even though
the overhead of calling scsi_test_unit_ready() is small for ATA zoned
devices, it is much larger for SCSI and it affects performance in a very
negative way.
Fix this performance regression by executing check_events() only in case
of any I/O errors. The function dmz_bdev_is_dying() is modified to call
only blk_queue_dying(), while calls to check_events() are made in a new
helper function, dmz_check_bdev().

The ast2600 no longer uses bit 4 in the control register to indicate a
1MHz clock (It now controls whether this watchdog is reset by a SOC
reset). This means we do not want to set it. It also does not need to be
set for the ast2500, as it is read-only on that SoC.
The comment next to the clock rate selection wandered away from where it
was set, so put it back next to the register setting it's describing.
