of: Add test managed wrappers for of_overlay_apply()/of_node_put()
Add test managed wrappers for of_overlay_apply() that automatically
removes the overlay when the test is finished. This API is intended for
use by KUnit tests that test code which relies on 'struct device_node's
and of_*() APIs.
KUnit tests will call of_overlay_apply_kunit() to load an overlay that's
been built into the kernel image. When the test is complete, the overlay
will be removed.
This has a few benefits:
1) It keeps the tests hermetic because the overlay is removed when the
test is complete. Tests won't even be aware that an overlay was
loaded in another test.
2) The overlay code can live right next to the unit test that loads it.
The overlay and the unit test can be compiled into one kernel module
if desired.
3) We can test different device tree configurations by loading
different overlays. The overlays can be written for a specific test,
and there can be many of them loaded per-test without needing to jam
all possible combinations into one DTB.
4) It also allows KUnit to test device tree dependent code on any
architecture, not just UML. This allows KUnit tests to test
architecture specific device tree code.
There are some potential pitfalls though. Test authors need to be
careful to not overwrite properties in the live tree. The easiest way to
do this is to add and remove nodes with a 'kunit-' prefix, almost
guaranteeing that the same node won't be present in the tree loaded at
boot.

of/platform: Allow overlays to create platform devices from the root node
We'd like to apply overlays to the root node in KUnit so we can test platform devices created as children of the root node. On some architectures (powerpc), the root node isn't marked with OF_POPULATED_BUS. If an overlay tries to modify the root node on these platforms it will fail, while on other platforms, such as ARM, it will succeed. This is because the root node is marked with OF_POPULATED_BUS by of_platform_default_populate_init() calling of_platform_default_populate() with NULL as the first argument. Loosen the requirement here so that platform devices can be created for nodes created as children of the root node via DT overlays even if the platform bus wasn't populated for the root node.

Networking changes for 6.10.
Core & protocols
----------------
- Complete rework of garbage collection of AF_UNIX sockets.
AF_UNIX is prone to forming reference count cycles due to fd passing
functionality. New method based on Tarjan's Strongly Connected Components
algorithm should be both faster and remove a lot of workarounds
we accumulated over the years.
- Add TCP fraglist GRO support, allowing chaining multiple TCP packets
and forwarding them together. Useful for small switches / routers which
lack basic checksum offload in some scenarios (e.g. PPPoE).
- Support using SMP threads for handling packet backlog i.e. packet
processing from software interfaces and old drivers which don't
use NAPI. This helps move the processing out of the softirq jumble.
- Continue work of converting from rtnl lock to RCU protection.
Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address
labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files,
MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs,
neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link
information available via rtnetlink.
- Small optimizations from Eric to UDP wake up handling, memory accounting,
RPS/RFS implementation, TCP packet sizing etc.
- Allow direct page recycling in the bulk API used by XDP, for +2% PPS.
- Support peek with an offset on TCP sockets.
- Add MPTCP APIs for querying last time packets were received/sent/acked,
and whether MPTCP "upgrade" succeeded on a TCP socket.
- Add intra-node communication shortcut to improve SMC performance.
- Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver.
- Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.
- Add reset reasons for tracing what caused a TCP reset to be sent.
- Introduce direction attribute for xfrm (IPSec) states.
State can be used either for input or output packet processing.
Things we sprinkled into general kernel code
--------------------------------------------
- Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().
This required touch-ups and renaming of a few existing users.
- Add Endian-dependent __counted_by_{le,be} annotations.
- Make building selftests "quieter" by printing summaries like
"CC object.o" rather than full commands with all the arguments.
Netfilter
---------
- Use GFP_KERNEL to clone elements, to deal better with OOM situations
and avoid failures in the .commit step.
BPF
---
- Add eBPF JIT for ARCv2 CPUs.
- Support attaching kprobe BPF programs through kprobe_multi link in
a session mode, meaning, a BPF program is attached to both function entry
and return, the entry program can decide if the return program gets
executed and the entry program can share u64 cookie value with return
program. "Session mode" is a common use-case for tetragon and bpftrace.
- Add the ability to specify and retrieve BPF cookie for raw tracepoint
programs in order to ease migration from classic to raw tracepoints.
- Add an internal-only BPF per-CPU instruction for resolving per-CPU
memory addresses and implement support in x86, ARM64 and RISC-V JITs.
This allows inlining functions which need to access per-CPU state.
- Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
atomics in bpf_arena which can be JITed as a single x86 instruction.
Support BPF arena on ARM64.
- Add a new bpf_wq API for deferring events and refactor process-context
bpf_timer code to keep common code where possible.
- Harden the BPF verifier's and/or/xor value tracking.
- Introduce crypto kfuncs to let BPF programs call kernel crypto APIs.
- Support bpf_tail_call_static() helper for BPF programs with GCC 13.
- Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
program to have code sections where preemption is disabled.
Driver API
----------
- Skip software TC processing completely if all installed rules are
marked as HW-only, instead of checking the HW-only flag rule by rule.
- Add support for configuring PoE (Power over Ethernet), similar to
the already existing support for PoDL (Power over Data Line) config.
- Initial bits of a queue control API, for now allowing a single queue
to be reset without disturbing packet flow to other queues.
- Common (ethtool) statistics for hardware timestamping.
Tests and tooling
-----------------
- Remove the need to create a config file to run the net forwarding tests
so that a naive "make run_tests" can exercise them.
- Define a method of writing tests which require an external endpoint
to communicate with (to send/receive data towards the test machine).
Add a few such tests.
- Create a shared code library for writing Python tests. Expose the YAML
Netlink library from tools/ to the tests for easy Netlink access.
- Move netfilter tests under net/, extend them, separate performance tests
from correctness tests, and iron out issues found by running them
"on every commit".
- Refactor BPF selftests to use common network helpers.
- Further work filling in YAML definitions of Netlink messages for:
nftables, team driver, bonding interfaces, vlan interfaces, VF info,
TC u32 mark, TC police action.
- Teach Python YAML Netlink to decode attribute policies.
- Extend the definition of the "indexed array" construct in the specs
to cover arrays of scalars rather than just nests.
- Add hyperlinks between definitions in generated Netlink docs.
Drivers
-------
- Make sure unsupported flower control flags are rejected by drivers,
and make more drivers report errors directly to the application rather
than dmesg (large number of driver changes from Asbjørn Sloth Tønnesen).
- Ethernet high-speed NICs:
- Broadcom (bnxt):
- support multiple RSS contexts and steering traffic to them

of: property: Add fw_devlink support for interrupt-map property
Some of the PCI host controllers (such as generic PCI host controller) use "interrupt-map" DT property to describe the mapping between PCI endpoints and PCI interrupt pins. This is the only case where the interrupts are not described in DT. Currently, there is no fw_devlink created based on "interrupt-map" DT property so interrupt controller is not guaranteed to be probed before the PCI host controller. This affects every platform where both PCI host controller and interrupt controllers are probed as regular platform devices. This creates fw_devlink between consumers (PCI host controller) and supplier (interrupt controller) based on "interrupt-map" DT property.

i2c: mux: Remove class argument from i2c_mux_add_adapter()
99a741aa7a2d ("i2c: mux: gpio: remove support for class-based device
instantiation") removed the last call to i2c_mux_add_adapter() with a
non-null class argument. Therefore the class argument can be removed.
Note: Class-based device instantiation is a legacy mechanism which
shouldn't be used in new code, so we can rule out that this argument
may be needed again in the future.

of: module: add buffer overflow check in of_modalias()
In of_modalias(), if the buffer happens to be too small even for the 1st
snprintf() call, the len parameter will become negative and str parameter
(if not NULL initially) will point beyond the buffer's end. Add the buffer
overflow check after the 1st snprintf() call and fix such check after the
strlen() call (accounting for the terminating NUL char).

of: reserved_mem: Remove the use of phandle from the reserved_mem APIs
The __find_rmem() function is the only place that references the phandle field of the reserved_mem struct. __find_rmem() is used to match a device_node object to its corresponding entry in the reserved_mem array using its phandle value. But, there is already a function called of_reserved_mem_lookup() which carries out the same action using the name of the node. Using the of_reserved_mem_lookup() function is more reliable because every node is guaranteed to have a name, but not all nodes will have a phandle. Nodes are only assigned a phandle if they are explicitly defined in the DT using "phandle = <phandle_number>", or if they are referenced by another node in the DT. Hence, If the phandle field is empty, then __find_rmem() will return a false negative. Hence, delete the __find_rmem() function and switch to using the of_reserved_mem_lookup() function to find the corresponding entry of a device_node in the reserved_mem array. Since the phandle field of the reserved_mem struct is now unused, delete that as well.

STM32 Firewall bus for v6.10, round 1
Highlights: --------- Introduce STM32 Firewall framework for STM32MP1x and STM32MP2x platforms. STM32MP1x(ETZPC) and STM32MP2x(RIFSC) Firewall controllers register to the framework to offer firewall services such as access granting. This series of patches is a new approach on the previous STM32 system bus, history is available here: https://lore.kernel.org/lkml/20230127164040.1047583/ The need for such framework arises from the fact that there are now multiple hardware firewalls implemented across multiple products. Drivers are shared between different products, using the same code. When it comes to firewalls, the purpose mostly stays the same: Protect hardware resources. But the implementation differs, and there are multiple types of firewalls: peripheral, memory, ... Some hardware firewall controllers such as the RIFSC implemented on STM32MP2x platforms may require to take ownership of a resource before being able to use it, hence the requirement for firewall services to take/release the ownership of such resources. On the other hand, hardware firewall configurations are becoming more and more complex. These mecanisms prevent platform crashes or other firewall-related incoveniences by denying access to some resources. The stm32 firewall framework offers an API that is defined in firewall controllers drivers to best fit the specificity of each firewall. For every peripherals protected by either the ETZPC or the RIFSC, the firewall framework checks the firewall controlelr registers to see if the peripheral's access is granted to the Linux kernel. If not, the peripheral is configured as secure, the node is marked populated, so that the driver is not probed for that device. The firewall framework relies on the access-controller device tree binding. It is used by peripherals to reference a domain access controller. In this case a firewall controller. The bus uses the ID referenced by the access-controller property to know where to look in the firewall to get the security configuration for the peripheral. This allows a device tree description rather than a hardcoded peripheral table in the bus driver. The STM32 ETZPC device is responsible for filtering accesses based on security level, or co-processor isolation for any resource connected to it. The RIFSC is responsible for filtering accesses based on Compartment ID / security level / privilege level for any resource connected to it. -----BEGIN PGP SIGNATURE----- iQJRBAABCgA7FiEEctl9+nxzUSUqdELdf5rJavIecIUFAmYqUUkdHGFsZXhhbmRy ZS50b3JndWVAZm9zcy5zdC5jb20ACgkQf5rJavIecIWolxAAqUHuLzXyrsCGfPG9 L5J8dUIeRk6lsQgO62EtS/hsUL5NhlwSiShtNilGw0t2TDCj0LpSMccwDjHoC1DE 9ks6aj0lO4dBl/d6fQm+4Vn85KiKfKYXW3J9w+6ZtG7pRly9jbmlrELqBIbL+MjU /mmPdKM5y/l9KO6vxiua+EtDdd0pZksZLFtms23VoiFgkQ+2heoJ297QGfrWwxzv UZg/UnWpQYB10dp93WL97vTdBZR4iUwEJNcip7xM65iBwSkuc9Y3gz0TZTO0ivZJ BRsNc/9BJYEV3kNxRJGyf7JeufsaG3meHVxw9sOYi2hMe75pDAANYxvsCYt6NHjL i+zugtcM5v//Ksw+HbD1rvRuhEWjFUotCeXJb+RaiY0Sy3HVlKG0WJm2Ybgzlbf+ vahskAHJxG0NFhPVpktQ/+gh8IU8Gy0PwyErdihhWKCiYBp8xHxW7IF7JtqlXQQS KQ4r0Ez/fgGmLQqDobskE+OgaFIuI5QrjH7S/VvxYh0xxZOBK89EmxK7pO3fki0v EFcTE/82HWfJo/bRCoq2Yzrh2omjR9ICsxDtVe4nILzjhaLChBz5lITyRO+/+Lr3 6u/oO09tlQYEK4YzH2Kw0xGtpY7Xfmm4wC+zDTRXKBM3Vp1IoTchHssLS4nZbScq ZHJHRPMCX98FdVH3BLX7OSexJys= =/Cu0 -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmYwAI4ACgkQYKtH/8kJ UicByw//VzXycIdrOzZeInbrhs0D/7pmb31U1NaAwtK3Y90lxBi5AlB4MKUrM+oq x/cxqmmW1RsBc2m1iEuJWkqXS+XJHGptHKAHUqVhI9bIuBZqmGddvcP93Ml9egcN OL/Kd/OS4Q07EYc/Md6XrRBo2zJcHT57jGH8fKBmX4eAKfPYo7xgbq5k/0LoCq/i cgfQdKeDsR6tTrHyJI0p/+EgS5uglUnIJBm1aLDk883UKH4/EQSR+dpvYsogBcbd UnH78QeUymCOYzWylHJHeWFgDnn9NiJy/oCQx7wMc6PVUhcd0l1FXvM7XUeDy7iW aNJpgYU8cTx9IYPGBbZJ13NX0+X4QACKpDjJZG90/y4Q4YEn5l/Di9rmv4HYhZgr gwYD4EHewKB3PVtmCCUQpurSblshoo9bPWEaR3NFD1mSu46Jb11/zgIQ4oBagixV MjiaaP3+Rpz1X0Zo5HSq9F0k4A/SddOo2zjMn3af/77nENsR3yEmPWgL20T+nv9P deJ/LqE6mGVFI0c4E2K03Y85wldN6xXyhvCEqlHtK2X4l5JMe+0Vnak+VICZ0jQw K/ihBRbifMH7g4GQUjpJUoUAvoyeSJ2jhMF8QV7bk76b6HeRFRYKOpQLnj29v/nd MF2rKJwFYqJDF3d2a90I3E8c7huKnqWHQWinKu2Y2NkmH/tqtcI= =mgY+ -----END PGP SIGNATURE----- Merge tag 'stm32-bus-firewall-for-v6.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/atorgue/stm32 into soc/drivers STM32 Firewall bus for v6.10, round 1 Highlights: --------- Introduce STM32 Firewall framework for STM32MP1x and STM32MP2x platforms.

of: dynamic: Synchronize of_changeset_destroy() with the devlink removals
In the following sequence:
1) of_platform_depopulate()
2) of_overlay_remove()
During the step 1, devices are destroyed and devlinks are removed.
During the step 2, OF nodes are destroyed but
__of_changeset_entry_destroy() can raise warnings related to missing
of_node_put():
ERROR: memory leak, expected refcount 1 instead of 2 ...
Indeed, during the devlink removals performed at step 1, the removal
itself releasing the device (and the attached of_node) is done by a job
queued in a workqueue and so, it is done asynchronously with respect to
function calls.
When the warning is present, of_node_put() will be called but wrongly
too late from the workqueue job.
In order to be sure that any ongoing devlink removals are done before
the of_node destruction, synchronize the of_changeset_destroy() with the
devlink removals.

Here is the big set of char/misc and a number of other driver subsystem
updates for 6.9-rc1. Included in here are:
- IIO driver updates, loads of new ones and evolution of existing ones
- coresight driver updates
- const cleanups for many driver subsystems
- speakup driver additions
- platform remove callback void cleanups
- mei driver updates
- mhi driver updates
- cdx driver updates for MSI interrupt handling
- nvmem driver updates
- other smaller driver updates and cleanups, full details in the
shortlog
All of these have been in linux-next for a long time with no reported
issue, other than a build warning with some older versions of gcc for a
speakup driver, fix for that will come in a few days when I catch up
with my pending patch queues.

The build warning hits clang and is a gcc (and C23) extension, and is
fixed up in the merge.

Not a ton of stuff happening in the clk framework in this pull request. We got
some more devm helpers and we seem to be going in the direction of "just turn
this stuff on already and leave me alone!" with the addition of a
devm_clk_bulk_get_all_enable() API. I'm hoping that we can make that into a
genpd that drivers attach instead, but this API should help drivers simplify in
the meantime.
Outside of the devm wrappers, we've got the usual clk driver updates that are
dominated by the major phone SoC vendors (Samsung and Qualcomm) and the
non-critical driver fixes for things like incorrect topology descriptions and
wrong registers or bit fields. More details are below, but I'd say that it
looks pretty ordinary. The only thing that really jumps out at me is the
Renesas clk driver that's ignoring clks that are assigned to remote processors
in DeviceTree. That's a new feature that they're using to avoid marking clks as
CLK_IGNORE_UNUSED based on the configuration of the system.
Core:
- Increase dev_id len for clkdev lookups
- Add a devm_clk_bulk_get_all_enable() API to get and enable all clks
for a device
- Add a devm variant of clk_rate_exclusive_get()
New Drivers:
- Display, TCSR, GPU, and Camera clock controllers for Qualcomm's X1 Elite SoC
- Google GS101 PERIC0 and PERIC1 clock controllers
- Exynos850 PDMA clocks
- Exynos850 CPU cluster 0 and 1 (CMU_CPUCLK0/CMU_CPUCLK1) clock controllers
Removed Drivers:
- Remove the unused Qualcomm sc7180 modem clk driver
Updates:
- Fix some static checker errors in the Hisilicon clk driver
- Polarfire MSSPLL hardware has 4 output clocks (the driver supported
previously only one output); each of these 4 outputs feed dividers and the
output of each divider feed individual hardware blocks (e.g. CAN, Crypto,
eMMC); individual hardware block drivers need to control their clocks thus
clock driver support was added for all MSSPLL output clocks
- Typo fixes in the Qualcomm IPQ5018 GCC driver
- Add "qdss_at" clk on Qualcomm IPQ6018, needed for WiFi
- Properly terminate frequency tables in different Qualcomm clk drivers
- Add MDSS, crypto, and SDCC resets on Qualcomm MSM8953
- Add missing UFS CLKREF clks on Qualcomm SC8180X
- Avoid significant delays during boot by adding a softdep on rpmhpd to
Qualcomm SDM845 gcc driver
- Add QUPv3 RCGS w/ DFS and video resets to Qualcomm SM8150 GCC driver
- Fix the custom GPU GX "do-nothing" method in the Qualcomm GDSC driver
- Add an external regulator to GX GDSC on Qualcomm SC8280XP GPU clk driver
- Switch display, GPU, video, and camera Qualcomm clk drivers to
module_platform_driver()
- Set a longer delay for Venus resets on many Qualcomm SoCs
- Correct the GDSC wait times in the Qualcomm SDM845 display clk driver
- Fix clock listing Oops on Amlogic axg
- New pll-rate for Rockchip rk3568
- i2s rate improvements for Rockchip rk3399
- Rockchip rk3588 syscon clock fixes and removal of overall clock-number from
the rk3588 binding header
- A prerequisite for later improvements to the Rockchip rk3588 linked clocks
- Minor clean-ups and error handling improvements in both composite-8m and SCU
i.MX clock drivers
- Fix for SAI_MCLK_SEL definition for i.MX8MP
- Register the Samsung CMU MISC clock controller earlier, so the Multi Core
Timer clocksource can use it on Google GS101
- Propagate Exynos850 SPI IPCLK rate change to parents, so the SPI will get
proper clock rates
- Refactor the generic Samsung CPU clock controllers code, preparing it for
supporting Exynos850 CPU clocks
- Fix some clk kerneldoc warnings
- Add Ethernet, SDHI, DMA, and HyperFLASH/QSPI (RPC-IF) clocks on Renesas
R-Car V4M
- Ignore all clocks which are assigned to a non-Linux system in the Renesas
clk driver
- Add watchdog clock on Renesas RZ/G3S
- Add camera (CRU) clock and reset on Renesas RZ/G2UL
- Add support for the Renesas R-Car V4M (R8A779H0) SoC
- Convert some clk bindings to YAML so they can be validated

- Sumanth Korikkar has taught s390 to allocate hotplug-time page frames
from hotplugged memory rather than only from main memory. Series
"implement "memmap on memory" feature on s390".
- More folio conversions from Matthew Wilcox in the series
"Convert memcontrol charge moving to use folios"
"mm: convert mm counter to take a folio"
- Chengming Zhou has optimized zswap's rbtree locking, providing
significant reductions in system time and modest but measurable
reductions in overall runtimes. The series is "mm/zswap: optimize the
scalability of zswap rb-tree".
- Chengming Zhou has also provided the series "mm/zswap: optimize zswap
lru list" which provides measurable runtime benefits in some
swap-intensive situations.
- And Chengming Zhou further optimizes zswap in the series "mm/zswap:
optimize for dynamic zswap_pools". Measured improvements are modest.
- zswap cleanups and simplifications from Yosry Ahmed in the series "mm:
zswap: simplify zswap_swapoff()".
- In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has
contributed several DAX cleanups as well as adding a sysfs tunable to
control the memmap_on_memory setting when the dax device is hotplugged
as system memory.
- Johannes Weiner has added the large series "mm: zswap: cleanups",
which does that.
- More DAMON work from SeongJae Park in the series
"mm/damon: make DAMON debugfs interface deprecation unignorable"
"selftests/damon: add more tests for core functionalities and corner cases"
"Docs/mm/damon: misc readability improvements"

- In the series "mm/mempolicy: weighted interleave mempolicy and sysfs
extension" Rakie Kim has developed a new mempolicy interleaving policy
wherein we allocate memory across nodes in a weighted fashion rather

tools to parse and process out selftesting results.
- Ryan Roberts has added fork()-time PTE batching of THP ptes in the
series "mm/memory: optimize fork() with PTE-mapped THP". Mainly
targeted at arm64, this significantly speeds up fork() when the process
has a large number of pte-mapped folios.
- David Hildenbrand also gets in on the THP pte batching game in his
series "mm/memory: optimize unmap/zap with PTE-mapped THP". It
implements batching during munmap() and other pte teardown situations.
The microbenchmark improvements are nice.
- And in the series "Transparent Contiguous PTEs for User Mappings" Ryan
Roberts further utilizes arm's pte's contiguous bit ("contpte
mappings"). Kernel build times on arm64 improved nicely. Ryan's series
"Address some contpte nits" provides some followup work.
- In the series "mm/hugetlb: Restore the reservation" Breno Leitao has
fixed an obscure hugetlb race which was causing unnecessary page faults.
He has also added a reproducer under the selftest code.
- In the series "selftests/mm: Output cleanups for the compaction test",
Mark Brown did what the title claims.
- Kinsey Ho has added the series "mm/mglru: code cleanup and refactoring".
- Even more zswap material from Nhat Pham. The series "fix and extend
zswap kselftests" does as claimed.
- In the series "Introduce cpu_dcache_is_aliasing() to fix DAX
regression" Mathieu Desnoyers has cleaned up and fixed rather a mess in
our handling of DAX on archiecctures which have virtually aliasing data
caches. The arm architecture is the main beneficiary.

in his series
"page_owner: print stacks and their outstanding allocations"
"page_owner: Fixup and cleanup"

in his series "Mitigate a vmap lock contention". It realizes a 12x
improvement for a certain microbenchmark.

pagecache writeback code in his series "convert write_cache_pages() to
an iterator".
- Some modest hugetlb cleanups and speedups in Vishal Moola's series
"Handle hugetlb faults under the VMA lock".

A simple example of the utility of this autocleanup approach to handling of_node_put(). In this particular case some of the nodes needed for the test are not available and the _available_ version would cause them to be skipped resulting in a test failure.

Add a KUnit test that confirms a DTB has been loaded, i.e. there is a root node, and that the of_have_populated_dt() API works properly. We skip the test when CONFIG_OF_EARLY_FLATREE=n because in that case we know architecture code hasn't called unflatten_(and_copy_)?device_tree() which would populate some sort of root node.

of: unittest: treat missing of_root as error instead of fixing up
unflatten_device_tree() now ensures that the 'of_root' node is populated with the root of a default empty devicetree. Remove the unittest code that created 'of_root' if it was missing. Verify that 'of_root' is valid before attempting to attach the testcase-data subtree.

um: Unconditionally call unflatten_device_tree()
Call this function unconditionally so that we can populate an empty DTB on platforms that don't boot with a command line provided DTB. There's no harm in calling unflatten_device_tree() unconditionally. If there isn't a valid initial_boot_params dtb then unflatten_device_tree() returns early.

of: Create of_root if no dtb provided by firmware
When enabling CONFIG_OF on a platform where 'of_root' is not populated by firmware, we end up without a root node. In order to apply overlays and create subnodes of the root node, we need one. Create this root node by unflattening an empty builtin dtb. If firmware provides a flattened device tree (FDT) then the FDT is unflattened via setup_arch(). Otherwise, the call to unflatten(_and_copy)?_device_tree() will create an empty root node. We make of_have_populated_dt() return true only if the DTB was loaded by firmware so that existing callers don't change behavior after this patch. The call in the of platform code is removed because it prevents overlays from creating platform devices when the empty root node is used.

of: Always unflatten in unflatten_and_copy_device_tree()
We want to populate an empty DT whenever CONFIG_OF is enabled so that overlays can be applied and the DT unit tests can be run. Make unflatten_and_copy_device_tree() stop printing a warning if the 'initial_boot_params' pointer is NULL. Instead, simply copy the dtb if there is one and then unflatten it. If there isn't a DT to copy, then the call to unflatten_device_tree() is largely a no-op, so nothing really changes here.
