The system might go into suspend during recovery of any remoteproc.
This will interrupt the recovery process in between increasing the
recovery time. Make the platform device as wakeup capable and
use pm_stay_wake/pm_relax APIs to avoid system from going into

The current name field used in the remoteproc structure is simply
a pointer to a name field supplied during the rproc_alloc() call.
The pointer passed in by remoteproc drivers during registration is
typically a dev_name pointer, but it is possible that the pointer
will no longer remain valid if the devices themselves were created
at runtime like in the case of of_platform_populate(), and were
deleted upon any failures within the respective remoteproc driver
probe function.
So, allocate and maintain a local copy for this name field to
keep it agnostic of the logic used in the remoteproc drivers.

Clients/services running on a remoteproc that booted up might need to be
aware of the state of already running remoteprocs. When a remoteproc boots
up (fresh or after recovery) it is not aware of the remoteprocs that booted

Current implementation of the sysmon driver does not support adding

Clients on the remoteproc side might be interested in knowing when a
remoteproc boots up. This change adds the ability to send the notification
type along with the name. For example, audio DSP is interested in knowing
when modem has crashed so that it can perform cleanup and wait for modem to
boot up before it starts processing data again.

If ida_simple_get() returns an error when called in rproc_alloc(),
put_device() is called to clean things up. By this time the rproc
device type has been assigned, with rproc_type_release() as the
release function.
The first thing rproc_type_release() does is call:
idr_destroy(&rproc->notifyids);
But at the time the ida_simple_get() call is made, the notifyids
field in the remoteproc structure has not been initialized.
I'm not actually sure this case causes an observable problem, but
it's incorrect. Fix this by initializing the notifyids field before
calling ida_simple_get() in rproc_alloc().

They are all supposed to be sorted, but people who add new entries don't
always know the alphabet. Plus sometimes the entry names get edited,
and people don't then re-order the entry.
Let's see how painful this will be for merging purposes (the MAINTAINERS

relatively few patches in -next that touch this, and doing it just
before -rc1 is likely the best time. Fingers crossed.

Pull scheduler fixes/updates from Thomas Gleixner:
- Deduplicate the average computations in the scheduler core and the
fair class code.
- Fix a raise between runtime distribution and assignement which can
cause exceeding the quota by up to 70%.
- Prevent negative results in the imbalanace calculation
- Remove a stale warning in the workqueue code which can be triggered
since the call site was moved out of preempt disabled code. It's a
false positive.
- Deduplicate the print macros for procfs
- Add the ucmap values to the SCHED_DEBUG procfs output for completness

sched/debug: Remove redundant macro define
sched/core: Remove unused rq::last_load_update_tick
workqueue: Remove the warning in wq_worker_sleeping()
sched/fair: Fix negative imbalance in imbalance calculation

- Fix the perf event cgroup tracking which tries to track the cgroup even
for disabled events.
- Add Ice Lake server support for uncore events
- Disable pagefaults when retrieving the physical address in the sampling
code.

Two types of #AC can be generated in Intel CPUs:
1. legacy alignment check #AC
2. split lock #AC
Reflect #AC back into the guest if the guest has legacy alignment checks
enabled or if split lock detection is disabled.
If the #AC is not a legacy one and split lock detection is enabled, then
invoke handle_guest_split_lock() which will either warn and disable split
lock detection for this task or force SIGBUS on it.
[ tglx: Switch it to handle_guest_split_lock() and rename the misnamed
helper function. ]
