There was a bug in ubifs related to the O_TMPFILE. When reapplying
changes after power cut data could be lost. This problem was exposed by
overlayfs and the upstream commit 3a1e819b4e80 ("ovl: store file handle
of lower inode on copy up").
This fixes a regression introduced when switching from 4.9 to 4.14.

Newer batches of several Mikrotik boards contain this yet-unsupported
flash chip, for instance:
- rb941-2nd (hAP lite)
- rb952ui-5ac2nd (hAP ac lite)
- RBM33G
and probably other Mikrotik boards need this patch as well.

starting from upstream commit 577b4eb23811 ("ubi: Reject MLC NAND")
it is not allowed to use UBI and UBIFS on a MLC flavoured NAND flash chip. [1]
According to David Oberhollenzer [2]:
The real problem is that on MLC NAND, pages come in pairs.
Multiple voltage levels inside a single, physical memory cell are used to
encode more than one bit. Instead of just having pages that are twice as big,
the flash exposes them as two different pages. Those pages are usually not
ordered sequentially either, but according to a vendor/device specific
pairing scheme.
Within OpenWrt, devices utilizing this type of flash,
combined with UBI(fs) will be bricked when a user upgrades
from 17.01.4 to a newer version as the MLC will be refused.
As these devices are currently advertised as supported by OpenWrt,
we should at least maintain the original state during the lifecycle
of the current releases.
Support can be gracefully ended when a new release-branch is created.

Compaction is the only memory management component to form high order (larger
physically contiguous) memory blocks reliably. The page allocator relies on
compaction heavily and the lack of the feature can lead to unexpected OOM
killer invocations for high order memory requests. You shouldn't disable this
option unless there really is a strong reason for it.

The intention of 967b6be118e3 ("ar8327: Add workarounds for AR8337
switch") was to remove the register fixups for AR8337. But instead they
were removed for AR8327.
The RGMII RX delay is forced even if the port is used as phy instead of
mac, which results in no package flow at least for one board.

The previous round of fixes for the 82574 chip cause an issue with
emulated e1000e devices in VMware ESXi 6.5. It also contains changes
that are not strictly necessary. These patches fix the issues introduced
in the previous series, revert the unnecessary changes to avoid
unforeseen fallout, and avoid a case where interrupts can be missed.
The final two patches of this series are already in the kernel, so no
need to include them here.
