Jon Hunter reported observing a build bug in the IPA driver:
https://lore.kernel.org/netdev/5b5d9d40-94d5-5dad-b861-fd9bef826...@nvidia.com
The problem is that the QMB0 max read value set for IPA v4.5 (16) is
too large to fit in the 4-bit field.

With the powercap dtpm controller, we are able to plug devices with
power limitation features in the tree.
The following patch introduces the CPU power limitation based on the
energy model and the performance states.
The power limitation is done at the performance domain level. If some

Yeah, this is fair to remove -- there are no users. I'm not a fan of

The density of components greatly increased the last decade bringing a
numerous number of heating sources which are monitored by more than 20
sensors on recent SoC. The skin temperature, which is the case
temperature of the device, must stay below approximately 45°C in order
to comply with the

Hi,
This patch series mainly extend Landlock rules to store the whole access
rights stack. This enables to tie access rights with their respective
layers to be able to have a sane semantic regardless of the previous
enforced rulesets. This also enables to get back the union of access

The sb_delete security hook is called when shutting down a superblock,

Thanks to the Landlock objects and ruleset, it is possible to identify

A Landlock ruleset is mainly a red-black tree with Landlock rules as
nodes. This enables quick update and lookup to match a requested

A Landlock object enables to identify a kernel object (e.g. an inode).
A Landlock rule is a set of access rights allowed on an object. Rules
are grouped in rulesets that may be tied to a set of processes (i.e.
subjects) to enforce a scoped access-control (i.e. a domain).

Test coverage for security/landlock/ is 94% of lines. The code not
covered only deals with internal kernel errors (e.g. memory allocation)
