0d5792c9bc Documentation: kunit: Make the KUnit documentation less UML-specific
Remove some of the outmoded "Why KUnit" rationale, and move some
UML-specific information to the kunit_tool page. Also update the Getting
Started guide to mention running tests without the kunit_tool wrapper.

62790268e4 ARM: SoC fixes
We've been accruing these for a couple of weeks, so the batch is a bit
 bigger than usual.
 
 Largest delta is due to a led-bl driver that is added -- there was
 a miscommunication before the merge window and the driver didn't make it
 in. Due to this, the platforms needing it regressed. At this point, it
 seemed easier to add the new driver than unwind the changes.
 
 Besides that, there are a handful of various fixes:
 
  - AMD tee memory leak fix
 
  - A handful of fixlets for i.MX SCU communication
 
  - A few maintainers woke up and realized DEBUG_FS had been missing for
    a while, so a few updates of that.
 
  ... and the usual collection of smaller fixes to various platforms.

b34e5c1332 Driver core / debugfs fixes for 5.6-rc5
Here are 4 small driver core / debugfs patches for 5.6-rc3
 
 They are:
 	- debugfs api cleanup now that all callers for
 	  debugfs_create_regset32() have been fixed up.  This was
 	  waiting until after the -rc1 merge as these fixes came in
 	  through different trees
 	- driver core sync state fixes based on reports of minor issues
 	  found in the feature
 
 All of these have been in linux-next with no reported issues.

d2334a91a3 dt-bindings: arm: Fixup the DT bindings for hierarchical PSCI states
The hierarchical topology with power-domain should be described through
child nodes, rather than as currently described in the PSCI root node. Fix
this by adding a patternProperties with a corresponding reference to the
power-domain DT binding.

Additionally, update the example to conform to the new pattern, but also to
the adjusted domain-idle-state DT binding.

8d62d9c4bc dt-bindings: arm: Correct links to idle states definitions
The arm,idle-state DT bindings recently got converted to the json-schema,
but some links are still pointing to the old, non-existing, txt file. Let's
update the links to fix this.

Fixes: baac82fe06 ("dt-bindings: arm: Convert arm,idle-state binding to DT schema")

Pull tracing and bootconfig updates:
 "Fixes and changes to bootconfig before it goes live in a release.

  Change in API of bootconfig (before it comes live in a release):
  - Have a magic value "BOOTCONFIG" in initrd to know a bootconfig
    exists
  - Set CONFIG_BOOT_CONFIG to 'n' by default
  - Show error if "bootconfig" on cmdline but not compiled in
  - Prevent redefining the same value
  - Have a way to append values
  - Added a SELECT BLK_DEV_INITRD to fix a build failure

  Synthetic event fixes:
  - Switch to raw_smp_processor_id() for recording CPU value in preempt
    section. (No care for what the value actually is)
  - Fix samples always recording u64 values
  - Fix endianess
  - Check number of values matches number of fields
  - Fix a printing bug

  Fix of trace_printk() breaking postponed start up tests

  Make a function static that is only used in a single file"

eccbde4f6c kbuild: remove wrong documentation about mandatory-y
This sentence does not make sense in the section about mandatory-y.

This seems to be a copy-paste mistake of commit fcc8487d47 ("uapi:
export all headers under uapi directories").

The correct description would be "The convention is to list one
mandatory-y per line ...".

I just removed it instead of fixing it. If such information is needed,
it could be commented in include/asm-generic/Kbuild and
include/uapi/asm-generic/Kbuild.

When there was no parallelism (no top-level -j arg and a pre-1.7

being missing, which would (understandably) badly confuse sphinx-build.

Pull arm64 fixes from Will Deacon:
 "It's all straightforward apart from the changes to mmap()/mremap() in
  relation to their handling of address arguments from userspace with
  non-zero tag bits in the upper byte.

  The change to brk() is necessary to fix a nasty user-visible
  regression in malloc(), but we tightened up mmap() and mremap() at the
  same time because they also allow the user to create virtual aliases
  by accident. It's much less likely than brk() to matter in practice,
  but enforcing the principle of "don't permit the creation of mappings
  using tagged addresses" leads to a straightforward ABI without having
  to worry about the "but what if a crazy program did foo?" aspect of
  things.

  Summary:

   - Fix regression in malloc() caused by ignored address tags in brk()

   - Add missing brackets around argument to untagged_addr() macro

   - Fix clang build when using binutils assembler

5f811c57c9 bootconfig: Add append value operator support
Add append value operator "+=" support to bootconfig syntax.
With this operator, user can add new value to the key as
an entry of array instead of overwriting.
For example,

  foo = bar
  ...
  foo += baz

Then the key "foo" has "bar" and "baz" values as an array.

4e4694d872 bootconfig: Prohibit re-defining value on same key
Currently, bootconfig adds a new value on the existing key to the tail of an
array. But this looks a bit confusing because an admin can easily rewrite
the original value in the same config file.

This rejects the following value re-definition.

  key = value1
  ...
  key = value2

You should rewrite value1 to value2 in this case.
