Now that the status of the maple state is outside of the node, the
mas_searchable() function can be dropped for easier open-coding of what is

The maple tree node is overloaded to keep status as well as the active
node. This, unfortunately, results in a re-walk on underflow or overflow.
Since the maple state has room, the status can be placed in its own enum
in the structure. Once an underflow/overflow is detected, certain modes
can restore the status to active and others may need to re-walk just that
one node to see the entry.
The status being an enum has the benefit of detecting unhandled status in
switch statements.

Analysis of the mas_for_each() iteration showed that there is a
significant time spent finding the end of a node. This time can be
greatly reduced if the end of the node is cached in the maple state. Care
must be taken to update & invalidate as necessary.

__mas_set_range() was created to shortcut resetting the maple state and a
debug check was added to the caller (the vma iterator) to ensure the
internal maple state remains safe to use. Move the debug check from the
vma iterator into the maple tree itself so other users do not incorrectly
use the advanced maple state modification.
Fallout from this change include a large amount of debug setup needed to
be moved to earlier in the header, and the maple_tree.h radix-tree test
code needed to move the inclusion of the header to after the atomic
define. None of those changes have functional changes.

perf_cpu_map__has_any_cpu_or_is_empty()
The name perf_cpu_map_empty is misleading as true is also returned
when the map contains an "any" CPU (aka dummy) map.
Rename to perf_cpu_map__has_any_cpu_or_is_empty(), later changes will
(re)introduce perf_cpu_map__empty() and perf_cpu_map__has_any_cpu().

perf_cpu_map__new_online_cpus() and prefer sysfs
Rename perf_cpu_map__default_new() to perf_cpu_map__new_online_cpus() to
better indicate what the implementation does.
Read the online CPUs from /sys/devices/system/cpu/online first before
using sysconf() as it can't accurately configure holes in the CPU map.
If sysconf() is used, warn when the configured and online processors
disagree.
When reading from a file, if the read doesn't yield a CPU map then
return an empty map rather than the default online. This avoids
recursion but also better yields being able to detect failures.
Add more comments.

`fs_kfuncs.c`'s `test_xattr` would fail the test even when the

Building the KVM selftests from the main selftests Makefile (as opposed
to the kvm subdirectory) doesn't work as OUTPUT is set, forcing the
generated header to spill into the selftests directory. Additionally,
relative paths do not work when building outside of the srctree, as the
canonical selftests path is replaced with 'kselftest' in the output.
Work around both of these issues by explicitly overriding OUTPUT on the
submake cmdline. Move the whole fragment below the point lib.mk gets
included such that $(abs_objdir) is available.

Out of tree builds are much more convenient when building for multiple
architectures or configurations in parallel.
Only absolute O= parameters are supported as Makefile.include will
always resolve relative paths in relation to $(srctree) instead of the
current directory.
Add a call to "make outputmakefile" to verify that the sourcetree is
clean.
This is based on Zhangjins out-of-tree patch.
It extends that work for get_init_cpio support and also drops relative
O= specifications explicitly.

qemu for LoongArch does not work properly with direct kernel boot.
The kernel will panic during initialization and hang without any output.
When booting in EFI mode everything work correctly.
While users most likely don't have the LoongArch EFI binary installed at
least an explicit error about 'file not found' is better than a hanging
test without output that can never succeed.

When TPIDR2 is not supported the tpidr2 ABI test prints the same message
for each skipped test:
ok 1 skipped, TPIDR2 not supported
which isn't ideal for test automation software since it tracks kselftest
results based on the string used to describe the test. This is also not
standard KTAP output, the expected format is:
ok 1 # SKIP default_value
Updated the program to generate this, using the same set of test names that
we would run if the test actually executed.

Patch series "samples: introduce cgroup events listeners", v3.
To begin with, this patch series relocates the cgroup example code to the
samples/cgroup directory, which is the appropriate location for such code
snippets.
Furthermore, a new memcg events listener is introduced. This listener is
a simple yet effective tool for monitoring memory events and managing
counter changes during runtime.
Additionally, as per Andrew Morton's suggestion, a helpful reminder
comment is included in the memcontrol implementation. This comment serves
to ensure that the samples code is updated whenever new events are added.
This patch (of 3):
Move the cgroup_event_listener for cgroup v1 to the samples directory.
This suggestion was proposed by Andrew Morton during the discussion [1].

The PAGEMAP_SCAN ioctl returns information regarding page table entries.
It is more efficient compared to reading pagemap files. CRIU can start to
utilize this ioctl, but it needs info about soft-dirty bits to track
memory changes.
We are aware of a new method for tracking memory changes implemented in
the PAGEMAP_SCAN ioctl. For CRIU, the primary advantage of this method is
its usability by unprivileged users. However, it is not feasible to
transparently replace the soft-dirty tracker with the new one. The main
problem here is userfault descriptors that have to be preserved between
pre-dump iterations. It means criu continues supporting the soft-dirty
method to avoid breakage for current users. The new method will be
implemented as a separate feature.
