The macro `ADF_RP_INT_SRC_SEL_F_RISE_MASK` is currently set to the value
`0100b` which means "Empty Going False". This might cause an incorrect
restore of the bank state during live migration.
Fix the definition of the macro to properly represent the "Full Going
True" state which is encoded as `0011b`.

The user space Jitter RNG library uses the oversampling rate of 3 which
implies that each time stamp is credited with 1/3 bit of entropy. To
obtain 256 bits of entropy, 768 time stamps need to be sampled. The
increase in OSR is applied based on a report where the Jitter RNG is
used on a system exhibiting a challenging environment to collect
entropy.
This OSR default value is now applied to the Linux kernel version of
the Jitter RNG as well.
The increase in the OSR from 1 to 3 also implies that the Jitter RNG is
now slower by default.

turns out that the 2G version has a DMI product name of

No consumers anymore, remove it. After this, insertion of policies
no longer require list walk of all inexact policies but only those
that are reachable via the candidate sets.
This gives almost linear insertion speeds provided the inserted
policies are for non-overlapping networks.

Inserted 1000 policies in 70 ms

XFRM_MIGRATE still uses the old lookup method:
first check the bydst hash table, then search the list of all the other
policies.
Switch MIGRATE to use the same lookup function as the packetpath.
This is done to remove the last remaining users of the pernet
xfrm.policy_inexact lists with the intent of removing this list.
After this patch, policies are still added to the list on insertion
and they are rehashed as-needed but no single API makes use of these
anymore.
This change is compile tested only.

Since commit
6be3b0db6d ("xfrm: policy: add inexact policy search tree infrastructure")
policy lookup no longer walks a list but has a set of candidate lists.
This set has to be searched for the best match.
In case there are several matches, the priority wins.
If the priority is also the same, then the historic behaviour with
a single list was to return the first match (first-in-list).
With introduction of serval lists, this doesn't work and a new
'pos' member was added that reflects the xfrm_policy structs position
in the list.
This value is not exported to userspace and it does not need to be
the 'position in the list', it just needs to make sure that
a->pos < b->pos means that a was added to the lists more recently
than b.
This re-walk is expensive when many inexact policies are in use.
Speed this up: when appending the policy to the end of the walker list,
then just take the ->pos value of the last entry made and add 1.
Add a slowpath version to prevent overflow, if we'd assign UINT_MAX
then iterate the entire list and fix the ordering.
While this speeds up insertion considerably finding the insertion spot
in the inexact list still requires a partial list walk.
This is addressed in followup patches.

Nothing special, just test how long insertion of x policies takes.
This should ideally show linear insertion speeds.
Do not run this by default, it has little value, but it can be useful to
check for insertion speed chahnges when altering the xfrm policy db

This adds a kfunc wrapper around strncpy_from_user,
which can be called from sleepable BPF programs.
This matches the non-sleepable 'bpf_probe_read_user_str'
helper except it includes an additional 'flags'
param, which allows consumers to clear the entire
destination buffer on success or failure.

The i915 driver generates sysfs entries for each engine of the
GPU in /sys/class/drm/cardX/engines/.
The process is straightforward: we loop over the UABI engines and
for each one, we:
- Create the object.
- Create basic files.
- If the engine supports timeslicing, create timeslice duration files.
- If the engine supports preemption, create preemption-related files.
- Create default value files.
Currently, if any of these steps fail, the process stops, and no
further sysfs files are created.
However, it's not necessary to stop the process on failure.
Instead, we can continue creating the remaining sysfs files for
the other engines. Even if some files fail to be created, the
list of engines can still be retrieved by querying i915.
