This is mainly a bug fix for multi-core MIPS systems where L1 caches besides the primary do not get flushed.
The most obvious problem is data corruption on SATA and USB devices where read requests are typically larger than the cacheline size.
This may also fix ar71xx systems that suffer from similar data corruption but I have not tested if it does.

This is important fix for flash parsing in some corner cases. In case
of TRX subpartition with rootfs being aligned to the flash block size it
was incorrectly registered twice. Detecting & registering it as a
standalone partition was resulting in an incorrect "firmware" partition
size and possibly broken sysupgrade.
It wasn't noticed before because "rootfs" alignment depends on a kernel
size. It can happen though - depending on the configuration and the
kernel size.

Add sysfs 'mode' attribute to swconfig controlled LEDs.
swconfig 'link state' LEDs blink in the presence of port traffic. This
behaviour becomes more obvious as switches start to support
get_port_stats() e.g. commits 0369e35891,
3056d09b40,
4ddbc43cc1,
4d8a66d934.
This blinking can be confusing/distracting if the switch has other LEDs
used to indicate traffic. Provide a 'mode' sysfs attribute that
controls the blink on traffic behaviour.
mode - either "none" (LED is off) or a space separated list of one or more:
link: LED's normal state reflects whether the link is up (has carrier) or not
tx: LED blinks on transmitted data
rx: LED blinks on receive data
Note that 'link' considers any port speed mask that may be applicable.
e.g. if an LED is configured to indicate 1Gbit link speed and mode is
set to 'link rx tx' but the port is connected at 100Mbit then the LED
will not light or blink. A mode of 'tx rx' will blink in the presence of
traffic only if the port matches the rate (if configured)
This maintains compatibility with existing behaviour.
Attribute is 'link tx rx' by default for backwards compatible behaviour.

routine after I had mangled the original, and other coding style hints.

Instead of creating an ubifs file system with format version 5 by
default on empty UBI volumes use the older format 4 by default. This
will make it possible to mount these file systems also on older kernel
versions.
When a user wants to do a sysupgrade from kernel 4.14 to kernel 4.9 the
old kernel has to read the file system created by the more recent kernel
which currently does not work for ubifs.
This fixes the problem by creating file systems which are compatible
with older kernel versions by default.
Kernel 4.14 will still be able to read and write UBI FS file system
version 5, it will just not be used when a ubifs partition is created
implicitly on an empty UBI volume.

This patch fixes the splitter to use the now correct header data.
Regarding target/linux/ar71xx/files/drivers/mtd/tplinkpart.c,
this particular splitter "falls back" to the correct rootfs offset
reading and as such it doesn't need to be updated, although it will
report a kernel partition length that can be larger than the actual
length as it assumes that partition fills the entire segment up to
