In addition to setting the ACK mask, also set the logical address mask
setting in the dongle. This (and not the ACK mask) is persisted for
use in autonomous mode.
The logical address mask to use is deduced from the primary device type
in adap->log_addrs.

nd_activate_region() iomaps any hint addresses required when activating
a region. To prevent duplicate mappings it checks the PFN of the hint to
be mapped against the PFNs of the already mapped hints. Unfortunately it
doesn't convert the PFN back into a physical address before passing it
to devm_nvdimm_ioremap(). Instead it applies PHYS_PFN a second time
which ends about as well as you would imagine.

Commit 44a7185c2ae6 ("of/platform: Add common method to populate
default bus") added new arch_initcall of_platform_default_populate_init()
that will override device_initcall octeon_publish_devices(). This broke
many OCTEON boards as important devices are not getting probed anymore
(e.g. on EdgeRouter Lite the USB mass storage/rootfs is missing).
Fix by changing octeon_publish_devices() to arch_initcall.

Commit 1685ddbe35cd ("MIPS: Octeon: Changes to support readq()/writeq()
usage.") added bitwise shift operations that assume that unsigned long
is always 64-bits. This broke the build of VDSO code, as it gets compiled
also in "faked" 32-bit mode. Althought the failing inline functions are
never executed in 32-bit mode, they still need to pass the compilation.
Fix by using 64-bit types explicitly.
The patch fixes the following build failure:

cpu_has_fpu macro uses smp_processor_id() and is currently executed
with preemption enabled, that triggers the warning at runtime.
It is assumed throughout the kernel that if any CPU has an FPU, then all
CPUs would have an FPU as well, so it is safe to perform the check with
preemption enabled - change the code to use raw_ variant of the check to
avoid the warning.

On a imx6ul-pico board the following error is seen during system suspend:
dpm_run_callback(): platform_pm_resume+0x0/0x54 returns -110
PM: Device 2090000.flexcan failed to resume: error -110
The reason for this suspend error is because when the CAN interface is not
active the clocks are disabled and then flexcan_chip_enable() will
always fail due to a timeout error.
In order to fix this issue, only call flexcan_chip_enable/disable()
when the CAN interface is active.
Based on a patch from Dong Aisheng in the NXP kernel.

commit 1a6509d99122 ("[IPSEC]: Add support for combined mode algorithms")
introduced aead. The function attach_aead kmemdup()s the algorithm
name during xfrm_state_construct().
However this memory is never freed.
Implementation has since been slightly modified in
commit ee5c23176fcc ("xfrm: Clone states properly on migration")
without resolving this leak.
This patch adds a kfree() call for the aead algorithm name.

commit a894cf6c5a82 ("mtd: nand: mxc: switch to mtd_ooblayout_ops")
introduced a regression accessing the OOB area from the mxc_nand
driver due to an Obiwan error in the mxc_nand_v[12]_ooblayout_free()
functions. They report a bogus oobregion { 64, 7 } which leads to
errors accessing bogus data when reading the oob area.
Prior to the commit the mtd-oobtest module could be run without any
errors. With the offending commit, this test fails with results like:

There is no point in trying to configure the trigger of a chained
interrupt if no trigger information has been configured. At best
this is ignored, and at the worse this confuses the underlying
irqchip (which is likely not to handle such a thing), and
unnecessarily alarms the user.
Only apply the configuration if type is not IRQ_TYPE_NONE.

Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an
unaligned 64 bit field (modifier). This get packed differently between
32 bit and 64 bit modes on architectures that can handle unaligned 64
bit access (X86 and IA64). Other architectures pack the structs the
same and don't need the compat wrapper. Use the same condition for
drm_mode_fb_cmd2 as we use for drm_update_draw.
Note that only the modifier will be packed differently between compat
and non-compat versions.

This removes the two #ifdef checks in this file and instead marks the
functions as __maybe_unused, which is a more reliable way of doing the
same, allowing better build coverage and avoiding the warning above.

Commit 6e7333d "net: add rx_nohandler stat counter" added the new entry
rx_nohandler into struct rtnl_link_stats64. Unfortunately the bna
driver foolishly depends on the structure. It uses part of it for
ethtool statistics and it's not bad but the driver assumes its size
is constant as it defines string for each existing entry. The problem
occurs when the structure is extended because you need to modify bna
driver as well. If not any attempt to retrieve ethtool statistics results
in crash in bnad_get_strings().
The patch changes BNAD_ETHTOOL_STATS_NUM so it counts real number of
strings in the array and also removes rtnl_link_stats64 entries that
are not used in output and are always zero.

skb is not freed if newsk is NULL. Rework the error path so free_skb is
unconditionally called on function exit.

A malicious TCP receiver, sending SACK, can force the sender to split
skbs in write queue and increase its memory usage.
Then, when socket is closed and its write queue purged, we might
overflow sk_forward_alloc (It becomes negative)
sk_mem_reclaim() does nothing in this case, and more than 2GB
are leaked from TCP perspective (tcp_memory_allocated is not changed)
Then warnings trigger from inet_sock_destruct() and
sk_stream_kill_queues() seeing a not zero sk_forward_alloc
All TCP stack can be stuck because TCP is under memory pressure.
A simple fix is to preemptively reclaim from sk_mem_uncharge().
This makes sure a socket wont have more than 2 MB forward allocated,
after burst and idle period.

If a TCP socket gets a large write queue, an overflow can happen
in a test in __tcp_retransmit_skb() preventing all retransmits.
The flow then stalls and resets after timeouts.
Tested:
sysctl -w net.core.wmem_max=1000000000
netperf -H dest -- -s 1000000000
