2021-03-30firmware: arm_scmi: Make notify_priv really privateCristian Marussi4-33/+40
Notification private data is currently accessible via handle->notify_priv, this data was indeed meant to be private to the notification core support and not to be accessible by SCMI drivers. Make it private hiding it inside instance descriptor struct scmi_info and accessible only via dedicated helpers.

As such, in the interface, a protocol handle will be passed down from the core to the protocol specific initialization callback at init time. Anyways, at this point only definitions are introduced, all protocols initialization code and SCMI drivers probing is still based on the old interface, so no functional change.

2021-03-15scmi-cpufreq: Get opp_shared_cpus from opp-v2 for EMNicola Mazzucato1-20/+54
By design, SCMI performance domains define the granularity of performance controls, they do not describe any underlying hardware dependencies (although they may match in many cases). It is therefore possible to have some platforms where hardware may have the ability to control CPU performance at different granularity and choose to describe fine-grained performance control through SCMI. In such situations, the energy model would be provided with inaccurate information based on controls, while it still needs to know the performance boundaries. To restore correct functionality, retrieve information of CPUs under the same performance domain from operating-points-v2 in DT, and pass it on to EM.

Pull io_uring fixes from Jens Axboe: "A bit of a mix between fallout from the worker change, cleanups and reductions now possible from that change, and fixes in general. In detail: - Fully serialize manager and worker creation, fixing races due to that. - Clean up some naming that had gone stale. - SQPOLL fixes. - Fix race condition around task_work rework that went into this merge window. - Implement unshare. Used for when the original task does unshare(2) or setuid/seteuid and friends, drops the original workers and forks new ones. - Drop the only remaining piece of state shuffling we had left, which was cred. Move it into issue instead, and we can drop all of that code too. - Kill f_op->flush() usage. That was such a nasty hack that we had out of necessity, we no longer need it. - Following from ->flush() removal, we can also drop various bits of ctx state related to SQPOLL and cancelations. - Fix an issue with IOPOLL retry, which originally was fallout from a filemap change (removing iov_iter_revert()), but uncovered an issue with iovec re-import too late. - Fix an issue with system suspend. - Use xchg() for fallback work, instead of cmpxchg(). - Properly destroy io-wq on exec. - Add create_io_thread() core helper, and use that in io-wq and io_uring. This allows us to remove various silly completion events related to thread setup. - A few error handling fixes. This should be the grunt of fixes necessary for the new workers, next week should be quieter. We've got a pending series from Pavel on cancelations, and how tasks and rings are indexed. Outside of that, should just be minor fixes. Even with these fixes, we're still killing a net ~80 lines" * tag 'io_uring-5.12-2021-03-05' of git://git.kernel.dk/linux-block: (41 commits) io_uring: don't restrict issue_flags for io_openat io_uring: make SQPOLL thread parking saner io-wq: kill hashed waitqueue before manager exits io_uring: clear IOCB_WAITQ for non -EIOCBQUEUED return io_uring: don't keep looping for more events if we can't flush overflow io_uring: move to using create_io_thread() kernel: provide create_io_thread() helper io_uring: reliably cancel linked timeouts io_uring: cancel-match based on flags io-wq: ensure all pending work is canceled on exit io_uring: ensure that threads freeze on suspend io_uring: remove extra in_idle wake up io_uring: inline __io_queue_async_work() io_uring: inline io_req_clean_work() io_uring: choose right tctx->io_wq for try cancel io_uring: fix -EAGAIN retry with IOPOLL io-wq: fix error path leak of buffered write hash map io_uring: remove sqo_task io_uring: kill sqo_dead and sqo submission halting io_uring: ignore double poll add on the same waitqueue head ...
