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.

Right patch version this time, sorry!
* Patch 180-usb-xhci-add-support-for-performing-fake-doorbell.patch had to be adjusted slightly because of upstream adapted code.
* Refreshed patches.

In the commit bde5e7a632 ("kernel: backport mtd implementation for
"compatible" in "partitions" subnode") patches that got accepted into
l2-mtd.git were backported to the kernels 4.9 and 4.14. Unfortunately
there was a regression report, patches were dropped and never reached
4.16.
This commit replaces these pseudo-backports with the latest version
that includes regression fix and futher changes that were requested.

This patch bumps the 4.14 kernel to .23.
- Refreshed patches.
- Deleted bcm53xx/patches-4.14/089-PCI-iproc-Fix-NULL-pointer-dereference-for-BCMA.patch. Has been accepted upstream.
- Deleted generic/pending-4.14/821-usb-Remove-annoying-warning-about-bogus-URB.patch. The upstream URB code was changed,
the patch no longer applies. I discussed this with the patch author and removed it for now, we'll see how it goes.

Somewhere in the kernel 4.9 migration process it looks like this patch
was broken. The update should be done when a device is added to the
bridge and when it gets removed, currently it is only done on the remove
path twice which does not make any sense.
I do not have a setup to test this now so this is only compile tested.

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 replaces the current patches used to make the kernel headers
compatible with musl with the version which was accepted upstream. This
is included in upstream kernel 4.15.
This was compile tested with iproute2 build on all supported kernel
versions with musl and one one with glibc.

This backports upstream support for "compatible" DT property set for the
"partitions" subnode of flash node. It allows specifying how partitions
should be created/parsed. Right now only "fixed-partitions" is
supported.
It should eventually replace our downstream "linux,part-probe" solution.

The underlying issue breaking Spansion flash has been fixed with "mtd: spi-nor:
wait until lock/unlock operations are ready" and "mtd: spi-nor: wait for SR_WIP
to clear on initial unlock", so we can support unlocking for Winbond flash
again.
This is necessary to have writable flash on certain UBNT devices with some
bootloader versions.

Rename unwinder config symbols to match upstream changes.
Refresh patches.
Update patch that no longer applies: 202-reduce_module_size.patch
Also enable CONFIG_PAGE_TABLE_ISOLATION. This feature was backported
from 4.15 to the 4.14 stable series. It is enabled by default, so enable
it in OpenWrt as well.

A few UBI messages lacks the trailing newline character which
leads to ugly lines in the bootlog like this:
[ 6.649159] UBI error: no valid UBI magic found inside mtd6[ 6.667751] Freeing unused kernel memory: 2196K
Add a newline character to the end of the messages to fix it.
After the fix the line from above looks better in the log:
[ 6.609182] UBI error: no valid UBI magic found inside mtd6
[ 6.627599] Freeing unused kernel memory: 2132K

This adds initial support for kernel 4.14 based on the patches for
kernel 4.9.
In the configuration I deactivated some of the new possible security
features like:
CONFIG_REFCOUNT_FULL
CONFIG_SLAB_FREELIST_HARDENED
CONFIG_SOFTLOCKUP_DETECTOR
CONFIG_WARN_ALL_UNSEEDED_RANDOM
And these overlay FS options are also deactivated:
CONFIG_OVERLAY_FS_INDEX
CONFIG_OVERLAY_FS_REDIRECT_DIR
I activated this:
CONFIG_FORTIFY_SOURCE
CONFIG_POSIX_TIMERS
CONFIG_SLAB_MERGE_DEFAULT
CONFIG_WATCHDOG_HANDLE_BOOT_ENABLED
I am not sure if I did the porting correct for the following patches:
target/linux/generic/backport-4.14/020-backport_netfilter_rtcache.patch
