To support one common PAI PMU device driver which handles
both PMUs pai_crypto and pai_ext, use a common naming scheme
for structures and variables suitable for both device drivers.
Add a common usable function pai_stop() for the event on a CPU.
Call this common pai_stop() from paicrypt_del().

Unify naming and logic for PAI PMU drivers to support both PMUs
pai_crypto and pai_ext.
Rename paicrypt_push_sample() to pai_push_sample() to reflect

and scheduler callbacks. Use struct pai_pmu to determine area_size
instead of PAGE_SIZE for counter backup.
Remove obsolete variable paicrypt_cnt.

Create and add a PMU characteristics table to store the parameters
of the PAI crypto PMU. This table contains PMU details such as
- number of available counters
- name of these counters to export to /sysfs
- Size of the memory mapped counter area
- base number of first counter
- etc
Also define a PMU specific initialization function to be called when
a PAI PMU feature is supported. At device driver initialization
test these features and if available use instruction qpaci to
retrieve the number of available counters. Also export these counter
names to /sysfs and register this PMU.

Currently if a user enqueues a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.
This lack of consistency cannot be addressed without refactoring the API.
alloc_workqueue() treats all queues as per-CPU by default, while unbound
workqueues must opt-in via WQ_UNBOUND.
This default is suboptimal: most workloads benefit from unbound queues,
allowing the scheduler to place worker threads where they’re needed and
reducing noise when CPUs are isolated.
This continues the effort to refactor workqueue APIs, which began with
the introduction of new workqueues and a new alloc_workqueue flag in:
commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag")
This change adds a new WQ_PERCPU flag to explicitly request alloc_workqueue()
to be per-cpu when WQ_UNBOUND has not been specified.
With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU.
Once migration is complete, WQ_UNBOUND can be removed and unbound will
become the implicit default.

The xfrm_add_acquire() function constructs an xfrm policy by calling
xfrm_policy_construct(). This allocates the policy structure and
potentially associates a security context and a device policy with it.
However, at the end of the function, the policy object is freed using
only kfree() . This skips the necessary cleanup for the security context
and device policy, leading to a memory leak.
To fix this, invoke the proper cleanup functions xfrm_dev_policy_delete(),
xfrm_dev_policy_free(), and security_xfrm_policy_free() before freeing the
policy object. This approach mirrors the error handling path in
xfrm_add_policy(), ensuring that all associated resources are correctly
released.
