This patch is aimed primarily at drivers/of/overlay.c, but those
changes also have a small impact in a few other files.
overlay.c is difficult to read and maintain. Improve readability:
- Rename functions, types and variables to better reflect what
they do and to be consistent with names in other places,
such as the device tree overlay FDT (flattened device tree),
and make the algorithms more clear
- Use the same names consistently throughout the file
- Update comments for name changes
- Fix incorrect comments
This patch is intended to not introduce any functional change.

"Another chunk of fmount preparations from dhowells; only trivial
conflicts for that part. It separates MS_... bits (very grotty
mount(2) ABI) from the struct super_block ->s_flags (kernel-internal,
only a small subset of MS_... stuff).
This does *not* convert the filesystems to new constants; only the
infrastructure is done here. The next step in that series is where the
conflicts would be; that's the conversion of filesystems. It's purely
mechanical and it's better done after the merge, so if you could run
something like

In this round, we've mostly tuned f2fs to provide better user experience
for Android. Especially, we've worked on atomic write feature again with
SQLite community in order to support it officially. And we added or modified
several facilities to analyze and enhance IO behaviors.
Major changes include:
- add app/fs io stat
- add inode checksum feature
- support project/journalled quota
- enhance atomic write with new ioctl() which exposes feature set
- enhance background gc/discard/fstrim flows with new gc_urgent mode
- add F2FS_IOC_FS{GET,SET}XATTR

This reverts commit 81f9507628.
It causes random failures of firmware loading at resume time (well,
random for me, it seems to be more reliable for others) because the
firmware disabling is not actually synchronous with any particular
resume event, and at least the btusb driver that uses a workqueue to
load the firmware at resume seems to occasionally hit the "firmware
loading is disabled" logic because the firmware loader hasn't gotten the
resume event yet.
Some kind of sanity check for not trying to load firmware when it's not
possible might be a good thing, but this commit was not it.
Greg seems to have silently suffered the same issue, and pointed to the
likely culprit, and Gabriel C verified the revert fixed it for him too.

Slightly more changes than usual this time:
- KDump Kernel IOMMU take-over code for AMD IOMMU. The code now
tries to preserve the mappings of the kernel so that master
aborts for devices are avoided. Master aborts cause some
devices to fail in the kdump kernel, so this code makes the
dump more likely to succeed when AMD IOMMU is enabled.
- Common flush queue implementation for IOVA code users. The
code is still optional, but AMD and Intel IOMMU drivers had
their own implementation which is now unified.
- Finish support for iommu-groups. All drivers implement this
feature now so that IOMMU core code can rely on it.
- Finish support for 'struct iommu_device' in iommu drivers. All
drivers now use the interface.
- New functions in the IOMMU-API for explicit IO/TLB flushing.
This will help to reduce the number of IO/TLB flushes when
IOMMU drivers support this interface.
- Support for mt2712 in the Mediatek IOMMU driver
- New IOMMU driver for QCOM hardware
- System PM support for ARM-SMMU
- Shutdown method for ARM-SMMU-v3
- Some constification patches
- Various other small improvements and fixes

This extends the Qualcomm GLINK implementation to support the additional
features used for communicating with modem and DSP coprocessors in modern
Qualcomm platforms.
In addition to this there's support for placing virtio RPMSG buffers in
non-System RAM.

"I ended up splitting the main pull request for this series into two,
mainly because of clashes between NVMe fixes that went into 4.13 after
the for-4.14 branches were split off. This pull request is mostly
NVMe, but not exclusively. In detail, it contains:
- Two pull request for NVMe changes from Christoph. Nothing new on
the feature front, basically just fixes all over the map for the
core bits, transport, rdma, etc.
- Series from Bart, cleaning up various bits in the BFQ scheduler.
- Series of bcache fixes, which has been lingering for a release or
two. Coly sent this in, but patches from various people in this
area.
- Set of patches for BFQ from Paolo himself, updating both
documentation and fixing some corner cases in performance.
- Series from Omar, attempting to now get the 4k loop support
correct. Our confidence level is higher this time.
- Series from Shaohua for loop as well, improving O_DIRECT
performance and fixing a use-after-free"

Describe device tree optional properties:
* aspeed,reset-type = "cpu|soc|system|none"
One of three different, mutually exclusive, values
"cpu" : ARM CPU reset on signal
"soc" : 'System on chip' reset
"system" : Full system reset
The value can also be set to "none" which indicates that no
reset of any kind is to be done via this watchdog. This assumes
another watchdog on the chip is to take care of resets.
* aspeed,external-signal - Generate external signal (WDT1 and WDT2 only)
* aspeed,alt-boot - Boot from alternate block on signal
