Since AMLogic's GPIOLIB does not support standard framework yet,
of_get_named_gpio_flags is replaced to use AMLogic's own framework such that
GPIO will be obtained from wrapper function.
FIXME: This is not a right way to support for gpio and pinctrl.

Since ODROID-C does not PMU, it won't stop or off completely. Hence this
reboot condition will reach to bootloader and halt the system.

In order to assign a boot media to SDHC block between SDCARD or eMMC,
different two device tree have to be maintained. But this is risky to
maintain. Hence add both properties of SDCARD and eMMC to each contoller, SDHC
and SDIO, remove one of them in U-boot. Finally Linux kernel will have proper
device tree with corresponding to boot deivce.

Since ODROIDC does not have PMU for voltage scaling, only required to

Since MESON8B has single SDHC and SDIO block, 'meson8b_odroidc.dtd' is to boot by sdcard
and 'meson8b_odroidc_emmc.dtd' by eMMC.

commit da87ca4d4c upstream.
Since commit 7787380336 "net_dma: mark broken" we no longer pin dma
engines active for the network-receive-offload use case. As a result
the ->free_chan_resources() that occurs after the driver self test no
longer has a NET_DMA induced ->alloc_chan_resources() to back it up. A
late firing irq can lead to ksoftirqd spinning indefinitely due to the
tasklet_disable() performed by ->free_chan_resources(). Only
->alloc_chan_resources() can clear this condition in affected kernels.
This problem has been present since commit 3e037454bc "I/OAT: Add
support for MSI and MSI-X" in 2.6.24, but is now exposed. Given the
NET_DMA use case is deprecated we can revisit moving the driver to use
threaded irqs. For now, just tear down the irq and tasklet properly by:
1/ Disable the irq from triggering the tasklet
2/ Disable the irq from re-arming
3/ Flush inflight interrupts
4/ Flush the timer
5/ Flush inflight tasklets

commit 1acacc0784 upstream.
dm_pool_close_thin_device() must be called if dm_set_target_max_io_len()
fails in thin_ctr(). Otherwise __pool_destroy() will fail because the
pool will still have an open thin device:
device-mapper: thin metadata: attempt to close pmd when 1 device(s) are still open
device-mapper: thin: __pool_destroy: dm_pool_metadata_close() failed.
Also, must establish error code if failing thin_ctr() because the pool
is in fail_io mode.

commit a1989b3300 upstream.
An invalid ioctl will never be valid, irrespective of whether multipath
has active paths or not. So for invalid ioctls we do not have to wait
for multipath to activate any paths, but can rather return an error
code immediately. This fix resolves numerous instances of:
udevd[]: worker [] unexpectedly returned with status 0x0100

commit e9baa9d9d5 upstream.
It appears that in the DMA40 driver the DMA tasklet will very
often dereference memory for a descriptor just free:d from the
DMA40 slab. Nothing happens because no other part of the driver
has yet had a chance to claim this memory, but it's really
nasty to dereference free:d memory, so let's check the flag
before the descriptor is free and store it in a bool variable.

commit 75135da0d6 upstream.
pci_get_device() decrements the reference count of "from" (last
argument) so when we break off the loop successfully we have only one
device reference - and we don't know which device we have. If we want
a reference to each device, we must take them explicitly and let
the pci_get_device() walk complete to avoid duplicate references.
This is serious, as over-putting device references will cause
the device to eventually disappear. Without this fix, the kernel
crashes after a few insmod/rmmod cycles.
Tested on an Intel S7000FC4UR system with a 7300 chipset.

commit 6f58c780e5 upstream.
A selective retransmission request (SRR) is a fibre-channel
protocol control request which provides support for requesting
retransmission of a data sequence in response to an issue such as
frame loss or corruption. These events are experienced
infrequently in fibre-channel based networks which makes
it difficult to test and assess codepaths which handle these
events.
We were fortunate enough, for some definition of fortunate, to
have a metro-area single-mode SAN link which, at 10 GBPS
sustained load levels, would consistently generate SRR's in
a SCST based target implementation using our SCST/in-kernel
Qlogic target interface driver. In response to an SRR the
in-kernel Qlogic target driver immediately panics resulting
in a catastrophic storage failure for serviced initiators.
The culprit was a debug statement in the qla_target.c file which
does not verify that a pointer to the SCSI CDB is not null.
The unchecked pointer dereference results in the kernel panic
and resultant system failure.
The other two references to the SCSI CDB by the SRR handling code
use a ternary operator to verify a non-null pointer is being
acted on. This patch simply adds a similar test to the implicated
debug statement.
This patch is a candidate for any stable kernel being maintained
since it addresses a potentially catastrophic event with
minimal downside.
