commit e3ebd894f0 upstream.
The smc91x driver defines a macro that compares its argument to
itself, apparently to get a true result while using its argument
to avoid a warning about unused local variables.
Unfortunately, this triggers a warning with gcc-6, as the comparison
is obviously useless:
drivers/net/ethernet/smsc/smc91x.c: In function 'smc_hardware_send_pkt':
drivers/net/ethernet/smsc/smc91x.c:563:14: error: self-comparison always evaluates to true [-Werror=tautological-compare]
if (!smc_special_trylock(&lp->lock, flags)) {
This replaces the macro with another one that behaves similarly,
with a cast to (void) to ensure the argument is used, and using
a literal 'true' as its value.

list_for_each_entry_reverse(subdrv, &subdrv->list, list) {
Here, the list_for_each_entry_reverse immediately terminates because
the subdrv pointer is compared to itself as the loop end condition.
If we were to take the current subdrv pointer as the start of the
list (as we would do if list_for_each_entry_reverse() was not a macro),
we would iterate backwards over the &exynos_drm_subdrv_list anchor,
which would be even worse.
Instead, we need to use list_for_each_entry_continue_reverse()
to go back over each subdrv that was successfully opened until
the first entry.

commit 1c387188c6 upstream.
The VT-d specification (§8.3.3) says:
‘Virtual Functions’ of a ‘Physical Function’ are under the scope
of the same remapping unit as the ‘Physical Function’.
The BIOS is not required to list all the possible VFs in the scope
tables, and arguably *shouldn't* make any attempt to do so, since there
could be a huge number of them.
This has been broken basically for ever — the VF is never going to match
against a specific unit's scope, so it ends up being assigned to the
INCLUDE_ALL IOMMU. Which was always actually correct by coincidence, but
now we're looking at Root-Complex integrated devices with SR-IOV support
it's going to start being wrong.
Fix it to simply use pci_physfn() before doing the lookup for PCI devices.

This patch fixes the indentation to reflect the actual meaning of the code,
though is it actually meant to be part of the "else" clause? (I'm a
compiler developer, not a kernel person). It also adds spaces around
the assignment, to placate checkpatch.pl.

turn that pointer into a normal non-const pointer.
I also tried to change the ata core code to make host->private_data

[ Upstream commit d2a145252c ]
A race between scanning and fc_remote_port_delete() may result in a
permanent stop if the device gets blocked before scsi_sysfs_add_sdev()
and unblocked after. The reason is that blocking a device sets both the
SDEV_BLOCKED state and the QUEUE_FLAG_STOPPED. However,
scsi_sysfs_add_sdev() unconditionally sets SDEV_RUNNING which causes the
device to be ignored by scsi_target_unblock() and thus never have its
QUEUE_FLAG_STOPPED cleared leading to a device which is apparently
running but has a stopped queue.
We actually have two places where SDEV_RUNNING is set: once in
scsi_add_lun() which respects the blocked flag and once in
scsi_sysfs_add_sdev() which doesn't. Since the second set is entirely
spurious, simply remove it to fix the problem.

Clearing the tuning bits should reset the tuning circuit. However there is
more to do. Reset the command and data lines for good measure, and then
for eMMC ensure the card is not still trying to process a tuning command by
sending a stop command.
Note the JEDEC eMMC specification says the stop command (CMD12) can be used
to stop a tuning command (CMD21) whereas the SD specification is silent on
the subject with respect to the SD tuning command (CMD19). Considering that
CMD12 is not a valid SDIO command, the stop command is sent only when the
tuning command is CMD21 i.e. for eMMC. That addresses cases seen so far
which have been on eMMC.
Note that this replaces the commit fe5fb2e3b5 ("mmc: sdhci: Reset cmd and
data circuits after tuning failure") which is being reverted for v4.9+.

[ Upstream commit f37fabb864 ]
In the critical sysfs entry the thermal hwmon was returning wrong
temperature to the user-space. It was reporting the temperature of the
first trip point instead of the temperature of critical trip point.
For example:
/sys/class/hwmon/hwmon0/temp1_crit:50000
/sys/class/thermal/thermal_zone0/trip_point_0_temp:50000
/sys/class/thermal/thermal_zone0/trip_point_0_type:active
/sys/class/thermal/thermal_zone0/trip_point_3_temp:120000
/sys/class/thermal/thermal_zone0/trip_point_3_type:critical
Since commit e68b16abd9 ("thermal: add hwmon sysfs I/F") the driver
have been registering a sysfs entry if get_crit_temp() callback was
provided. However when accessed, it was calling get_trip_temp() instead
of the get_crit_temp().

[ Upstream commit e8d7c33232 ]
Current implementation employ 16bit counter of active stripes in lower
bits of bio->bi_phys_segments. If request is big enough to overflow
this counter bio will be completed and freed too early.
Fortunately this not happens in default configuration because several
other limits prevent that: stripe_cache_size * nr_disks effectively
limits count of active stripes. And small max_sectors_kb at lower
disks prevent that during normal read/write operations.
Overflow easily happens in discard if it's enabled by module parameter
"devices_handle_discard_safely" and stripe_cache_size is set big enough.
This patch limits requests size with 256Mb - 8Kb to prevent overflows.

[ Upstream commit 265e9098ba ]
In crypt_set_key(), if a failure occurs while replacing the old key
(e.g. tfm->setkey() fails) the key must not have DM_CRYPT_KEY_VALID flag
set. Otherwise, the crypto layer would have an invalid key that still
has DM_CRYPT_KEY_VALID flag set.
