vfprintf() is complex and so far did not have proper tests.
This series is based on the "dev" branch of the RCU tree.

memalign() is obsolete according to its manpage.
Replace memalign() with posix_memalign()
As a pointer is passed into posix_memalign(), initialize *one_page
to NULL to silence a warning about the function's return value being
used as uninitialized (which is not valid anyway because the error
is properly checked before one_page is returned).

2.27.0
Here is a series with some fixes and cleanups to resctrl selftests and
rewrite of CAT test into something that really tests CAT working or not
condition.
I know that this series will conflict with some of patches from
Shaopeng Tan that so far have not made it into the kselftest tree. Due
to CAT test rewrite done in this series, some of those patches would no
longer be relevant anyway but some of them are still very valid (I've
not tried to reinvent the fixes in Shaopeng's series in this series).
Ilpo Järvinen (22):
selftests/resctrl: Add resctrl.h into build deps
selftests/resctrl: Check also too low values for CBM bits
selftests/resctrl: Make span unsigned long everywhere
selftests/resctrl: Express span in bytes
selftests/resctrl: Remove duplicated preparation for span arg
selftests/resctrl: Don't use variable argument list for ->setup()
selftests/resctrl: Remove "malloc_and_init_memory" param from
run_fill_buf()
selftests/resctrl: Split run_fill_buf() to alloc, work, and dealloc
helpers
selftests/resctrl: Remove start_buf local variable from buffer alloc
func
selftests/resctrl: Don't pass test name to fill_buf
selftests/resctrl: Add flush_buffer() to fill_buf
selftests/resctrl: Remove test type checks from cat_val()
selftests/resctrl: Refactor get_cbm_mask()
selftests/resctrl: Create cache_alloc_size() helper
selftests/resctrl: Replace count_bits with count_consecutive_bits()
selftests/resctrl: Exclude shareable bits from schemata in CAT test
selftests/resctrl: Pass the real number of tests to show_cache_info()
selftests/resctrl: Move CAT/CMT test global vars to func they are used
selftests/resctrl: Read in less obvious order to defeat prefetch
optimizations

[ Upstream commit f1594bc676579133a3cd906d7d27733289edfb86 ]
When compiling selftests with target mount_setattr I encountered some errors with the below messages:
mount_setattr_test.c: In function ‘mount_setattr_thread’:
mount_setattr_test.c:343:16: error: variable ‘attr’ has initializer but incomplete type
343 | struct mount_attr attr = {

These errors might be because of linux/mount.h is not included. This patch resolves that issue.

2.39.2
This patch series adds unit tests for the clk fixed rate basic type and
the clk registration functions that use struct clk_parent_data. To get
there, we add support for loading device tree overlays onto the live DTB
along with probing platform drivers to bind to device nodes in the
overlays. With this series, we're able to exercise some of the code in
the common clk framework that uses devicetree lookups to find parents
and the fixed rate clk code that scans device tree directly and creates
clks. Please review.
I Cced everyone to all the patches so they get the full context. I'm
hoping I can take the whole pile through the clk tree as they almost all
depend on each other.
Changes from v2 (https://lore.kernel.org/r/20230315183729.2376178-1-sboyd@kernel.org):
* Overlays don't depend on __symbols__ node
* Depend on Frank's always create root node if CONFIG_OF series[1]
* Added kernel-doc to KUnit API doc
* Fixed some kernel-doc on functions
* More test cases for fixed rate clk
Changes from v1 (https://lore.kernel.org/r/20230302013822.1808711-1-sboyd@kernel.org):
* Don't depend on UML, use unittest data approach to attach nodes
* Introduce overlay loading API for KUnit
* Move platform_device KUnit code to drivers/base/test
* Use #define macros for constants shared between unit tests and
overlays
* Settle on "test" as a vendor prefix
* Make KUnit wrappers have "_kunit" postfix
Stephen Boyd (11):
of: Add KUnit test to confirm DTB is loaded
of: Add test managed wrappers for of_overlay_apply()/of_node_put()
dt-bindings: vendor-prefixes: Add "test" vendor for KUnit and friends
dt-bindings: test: Add KUnit empty node binding
of: Add a KUnit test for overlays and test managed APIs
platform: Add test managed platform_device/driver APIs
dt-bindings: kunit: Add fixed rate clk consumer test
clk: Add test managed clk provider/consumer APIs
clk: Add KUnit tests for clk fixed rate basic type
dt-bindings: clk: Add KUnit clk_parent_data test
clk: Add KUnit tests for clks registered with struct clk_parent_data
