2022-09-20ALSA: hda: ext: fix locking in stream_releasePierre-Louis Bossart
The snd_hdac_ext_stream_release() routine uses the bus reg_lock, but releases it before calling snd_hdac_stream_release() where the bus reg_lock is taken again. This creates a timing window where the link stream release could test an invalid 'opened' boolean status and fail to recouple the host and link parts. Fix by exposing a locked version of snd_hdac_stream_release() and use it without releasing the spinlock.

2022-09-19lib/cpumask: deprecate nr_cpumask_bitsYury Norov
Cpumask code is written in assumption that when CONFIG_CPUMASK_OFFSTACK is enabled, all cpumasks have boot-time defined size, otherwise the size is always NR_CPUS. The latter is wrong because the number of possible cpus is always calculated on boot, and it may be less than NR_CPUS. On my 4-cpu arm64 VM the nr_cpu_ids is 4, as expected, and nr_cpumask_bits is 256, which corresponds to NR_CPUS. This not only leads to useless traversing of cpumask bits greater than 4, this also makes some cpumask routines fail. For example, cpumask_full(0b1111000..000) would erroneously return false in the example above because tail bits in the mask are all unset. This patch deprecates nr_cpumask_bits and wires it to nr_cpu_ids unconditionally, so that cpumask routines will not waste time traversing unused part of cpu masks. It also fixes cpumask_full() and similar routines. As a side effect, because now a length of cpumasks is defined at run-time even if CPUMASK_OFFSTACK is disabled, compiler can't optimize corresponding functions. It increases kernel size by ~2.5KB if OFFSTACK is off. This is addressed in the following patch. Signed-off-by: Yury Norov <yury.norov@gmail.com>

commit 509853f9e1e7b ("genirq: Provide generic_handle_irq_safe()") addressed the problem of demultiplexing interrupt handlers which are force threaded on PREEMPT_RT enabled kernels which means that the demultiplexed handler is invoked with interrupts enabled which triggers a lockdep warning due to a non-irq safe lock acquisition. The same problem exists for the irq domain based interrupt handling via generic_handle_domain_irq() which has been reported against the AMD pin-ctrl driver.

2022-09-18habanalabs/gaudi2: new API to control engine cores running modeTal Cohen
The current flow of halting the engine cores is implemented by command buffers built by the user space and sent towards the Driver. This current flow is broken since the user space does not know when the cores actually halt as sending a workload is async op. Therefore the application can not free the memory that is mapped to the engine cores. This new API allows the user space to control the running mode. The API call is sync (returns after the cores are set to the requested mode).

2022-09-18habanalabs: add uapi to retrieve engines statusDani Liberman
Currently, to get engines status, user needed to read debugfs file with root permissions. This new uapi allows user apace apps retrieve status, so for example, in case of failure, status can be retrieved immediately by the application itself which runs without root permissions.
