kmemleak reports several memory leaks from devicetree unittest.
This is the fix for problem 5 of 5.
When overlay 'overlay_bad_add_dup_prop' is applied, the apply code
properly detects that a memory leak will occur if the overlay is removed
since the duplicate property is located in a base devicetree node and
reports via printk():
OF: overlay: WARNING: memory leak will occur if overlay removed, property: /testcase-data-2/substation@100/motor-1/rpm_avail
OF: overlay: WARNING: memory leak will occur if overlay removed, property: /testcase-data-2/substation@100/motor-1/rpm_avail
The overlay is removed when the apply code detects multiple changesets
modifying the same property. This is reported via printk():
OF: overlay: ERROR: multiple fragments add, update, and/or delete property /testcase-data-2/substation@100/motor-1/rpm_avail
As a result of this error, the overlay is removed resulting in the
expected memory leak.
Add another device node level to the overlay so that the duplicate
property is located in a node added by the overlay, thus no memory
leak will occur when the overlay is removed.
Thus users of kmemleak will not have to debug this leak in the future.

kernel test robot reported "WARNING: held lock freed!" triggered by
unittest_gpio_remove(), which should not have been called because
the related gpio overlay was not tracked. Another overlay that
was tracked had previously used the same id as the gpio overlay
but had not been untracked when the overlay was removed. Thus the
clean up function of_unittest_destroy_tracked_overlays() incorrectly
attempted to remove the reused overlay id.
Patch contents:
- Create tracking related helper functions
- Change BUG() to WARN_ON() for overlay id related issues
- Add some additional error checking for valid overlay id values
- Add the missing overlay untrack
- update comment on expectation that overlay ids are assigned in
sequence

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

Some tests in the devicetree unittests result in printk messages
from the code being tested. It can be difficult to determine
whether the messages are the result of unittest or are potentially
reporting bugs that should be fixed. The most recent example of
a person asking whether to be concerned about these messages is [1].
Add annotations for all messages triggered by unittests, except
KERN_DEBUG messages. (KERN_DEBUG is a special case due to the
possible interaction of CONFIG_DYNAMIC_DEBUG.)
The format of the annotations is expected to change when unittests
are converted to use the kunit infrastructure when the broader
testing community has an opportunity to discuss the implementation
of annotations of test triggered messages.

Certain SoCs need to support a large amount of reserved memory
regions. For example, Qualcomm's SM8150 SoC requires that 20
regions of memory be reserved for a variety of reasons (e.g.
loading a peripheral subsystem's firmware image into a
particular space).
When adding more reserved memory regions to cater to different
usecases, the remaining number of reserved memory regions--12
to be exact--becomes too small. Thus, double the existing
limit of reserved memory regions.

Currently, the DMA offset and mask for a device are set based only on the
first 'dma-ranges' entry. We should really be using all the entries. The
kernel doesn't yet support multiple offsets and sizes, so the best we can
do is to find the biggest size for a single offset. The algorithm is
copied from acpi_dma_get_range().
If there's different offsets from the first entry, then we warn and
continue. It really should be an error, but this will likely break
existing DTs.

There's an OF helper called of_dma_is_coherent(), which checks if a
device has a "dma-coherent" property to see if the device is coherent
for DMA.
But on some platforms devices are coherent by default, and on some
platforms it's not possible to update existing device trees to add the
"dma-coherent" property.
So add a Kconfig symbol to allow arch code to tell
of_dma_is_coherent() that devices are coherent by default, regardless
of the presence of the property.

There used to be blank lines between assignment and check of the
__of_changeset_revert_entries() result, to make the phandle cache
management operations stand out. After the removal of those operations
in commit 90dc0d1ce890419f ("of: Rework and simplify phandle cache to
use a fixed size"), there is no longer a reason to have such a blank
line.
Remove the blank line, to rejoin visibly the status assignement and
check, and to match coding style.

The CPU's idle state nodes are currently parsed at the common cpuidle DT
library, but also when initializing data for specific CPU idle operations,
as in the PSCI cpuidle driver case and qcom-spm cpuidle case.
To avoid open-coding, let's introduce of_get_cpu_state_node(), which takes
the device node for the CPU and the index to the requested idle state node,
as in-parameters. In case a corresponding idle state node is found, it
returns the node with the refcount incremented for it, else it returns
NULL.
Moreover, for PSCI there are two options to describe the CPU's idle states
[1], either via a flattened description or a hierarchical layout. Hence,
let's take both options into account.

The phandle cache was added to speed up of_find_node_by_phandle() by
avoiding walking the whole DT to find a matching phandle. The
implementation has several shortcomings:
- The cache is designed to work on a linear set of phandle values.
This is true for dtc generated DTs, but not for other cases such as
Power.
- The cache isn't enabled until of_core_init() and a typical system
may see hundreds of calls to of_find_node_by_phandle() before that
point.
- The cache is freed and re-allocated when the number of phandles
changes.
- It takes a raw spinlock around a memory allocation which breaks on
RT.
Change the implementation to a fixed size and use hash_32() as the
cache index. This greatly simplifies the implementation. It avoids
the need for any re-alloc of the cache and taking a reference on nodes
in the cache. We only have a single source of removing cache entries
which is of_detach_node().
Using hash_32() removes any assumption on phandle values improving
the hit rate for non-linear phandle values. The effect on linear values
using hash_32() is about a 10% collision. The chances of thrashing on
colliding values seems to be low.
To compare performance, I used a RK3399 board which is a pretty typical
system. I found that just measuring boot time as done previously is
noisy and may be impacted by other things. Also bringing up secondary
cores causes some issues with measuring, so I booted with 'nr_cpus=1'.
With no caching, calls to of_find_node_by_phandle() take about 20124 us
for 1248 calls. There's an additional 288 calls before time keeping is
up. Using the average time per hit/miss with the cache, we can calculate
these calls to take 690 us (277 hit / 11 miss) with a 128 entry cache
and 13319 us with no cache or an uninitialized cache.
Comparing the 3 implementations the time spent in
of_find_node_by_phandle() is:
no cache: 20124 us (+ 13319 us)
128 entry cache: 5134 us (+ 690 us)
current cache: 819 us (+ 13319 us)
We could move the allocation of the cache earlier to improve the
current cache, but that just further complicates the situation as it
needs to be after slab is up, so we can't do it when unflattening (which
uses memblock).

Commit 5e6669387e22 ("of/platform: Pause/resume sync state during init
and of_platform_populate()") paused/resumed sync state during init only
if Linux had parsed and populated a devicetree.
However, the check for that (of_have_populated_dt()) can change after
of_platform_default_populate_init() executes. One example of this is
when devicetree unittests are enabled. This causes an unmatched
pause/resume of sync state. To avoid this, just unconditionally
pause/resume sync state during init.

Pull driver core updates from Greg KH:
"Here is the "big" set of driver core patches for 5.5-rc1
There's a few minor cleanups and fixes in here, but the majority of
the patches in here fall into two buckets:
- debugfs api cleanups and fixes
- driver core device link support for boot dependancy issues
The debugfs api cleanups are working to slowly refactor the debugfs
apis so that it is even harder to use incorrectly. That work has been
happening for the past few kernel releases and will continue over
time, it's a long-term project/goal
The driver core device link support missed 5.4 by just a bit, so it's
been sitting and baking for many months now. It's from Saravana Kannan
to help resolve the problems that DT-based systems have at boot time
with dependancy graphs and kernel modules. Turns out that no one has
actually tried to build a generic arm64 kernel with loads of modules
and have it "just work" for a variety of platforms (like a distro
kernel). The big problem turned out to be a lack of dependency
information between different areas of DT entries, and the work here
resolves that problem and now allows devices to boot properly, and
quicker than a monolith kernel.
All of these patches have been in linux-next for a long time with no
reported issues"
