Move the kfree(host) calls into srp_release_dev(). Convert a
device_unregister() call into a device_del() and a device_put() call.
Remove the host->released completion object. This patch prepares for
handling dev_set_name() failure in srp_add_port().

device_register() always calls device_initialize() so calling device_del()
is safe even if device_register() fails. Implement the following advice
from the comment block above device_register(): "NOTE: _Never_ directly free
@dev after calling this function, even if it returned an error! Always use
put_device() to give up the reference initialized in this function instead."
Keep the kfree() call in the error path since srp_release_dev() does not
free the host.

syzbot is reporting hung task at __input_unregister_device() [1], for
iforce_close() waiting at wait_event_interruptible() with dev->mutex held
is blocking input_disconnect_device() from __input_unregister_device().
It seems that the cause is simply that commit c2b27ef672 ("Input:
iforce - wait for command completion when closing the device") forgot to
call wake_up() after clear_bit().
Fix this problem by introducing a helper that calls clear_bit() followed
by wake_up_all().

that it means we are no longer tracking purgeable or willneed buffers
that are active separately. But the most recently pinned buffers should
be at the tail of the various LRUs, and the shrinker is already prepared

Add a simple LRU helper to assist with driver's shrinker implementation.
It handles tracking the number of backing pages associated with a given
LRU, and provides a helper to implement shrinker_scan.
A driver can use multiple LRU instances to track objects in various
states, for example a dontneed LRU for purgeable objects, a willneed LRU
for evictable objects, and an unpinned LRU for objects without backing
pages.
All LRUs that the object can be moved between must share a single lock.

The Intel hybrid description is written in a different style than the
rest of the perf record man page. There were some new command line
options added after it which resulted in very strange section ordering.
Move the hybrid include last.
Also the sub sections in the hybrid document don't fit the record
manpage well (especially since it talks about all kinds of unrelated
commands). I left this for now, but would be better to separate this
properly in the different man pages.
It would be better to use sub sections for the other sections, but these
don't seem to be supported in AsciiDoc?
Some of the examples are still misrendered in the manpage with an
indented troff command, but I don't know how to fix that.
In any case it's now better than before.

That doesn't result in any changes in tooling (when built on x86), only
addresses this perf build warning:

The previous change to Python autodetection had a small mistake where
the auto value was used to determine the Python binary, rather than the
user supplied value. The Python binary is only used for one part of the
build process, rather than the final linking, so it was producing
correct builds in most scenarios, especially when the auto detected
value matched what the user wanted, or the system only had a valid set
of Pythons.
Change it so that the Python binary path is derived from either the
PYTHON_CONFIG value or PYTHON value, depending on what is specified by
the user. This was the original intention.
This error was spotted in a build failure an odd cross compilation
environment after commit 4c41cb46a7 ("perf python: Prefer
python3") was merged.
Fixes: 630af16eee ("perf tools: Use Python devtools for version autodetection rather than runtime")

Due to bpf_map_lookup_elem being declared static we need to also
declare subprog_noise as static.
Fixes the following error:
progs/tailcall_bpf2bpf4.c:26:9: error: 'bpf_map_lookup_elem' is static but used in inline function 'subprog_noise' which is not static [-Werror]
26 | bpf_map_lookup_elem(&nop_table, &key);

The "fixed_link" is only allocated sometimes but it's freed
unconditionally in the error handling. Set it to NULL so we don't free

Referenced commit introduced nfp_policer_validate in the progress
installing rate limiter. This validate check the action id and will
reject police with CONTINUE, which is required to support ingress
police offload.
Fix this issue by allowing FLOW_ACTION_CONTINUE as notexceed action
id in nfp_policer_validate

====================
openvswitch: allow specifying ifindex of new interfaces
CRIU currently do not support checkpoint/restore of OVS configurations, but
there was several requests for it. For example,
https://github.com/lxc/lxc/issues/2909
The main problem is ifindexes of newly created interfaces. We realy need to
preserve them after restore. Current openvswitch API does not allow to
specify ifindex. Most of the time we can just create an interface via
generic netlink requests and plug it into ovs but datapaths (generally any
OVS_VPORT_TYPE_INTERNAL) can only be created via openvswitch requests which
do not support selecting ifindex.
This patch allows to do so.
For new datapaths I decided to use dp_infindex in header as infindex
because it control ifindex for other requests too.
For internal vports I reused OVS_VPORT_ATTR_IFINDEX.
The only concern I have is that previously dp_ifindex was not used for
OVS_DP_VMD_NEW requests and some software may not set it to zero. However
we have been running this patch at Virtuozzo for 2 years and have not
encountered this problem. Not sure if it is worth to add new
ovs_datapath_attr instead.

CRIU is preserving ifindexes of net devices after restoration. However,
current Open vSwitch API does not allow to target ifindex, so we cannot
correctly restore OVS configuration.
Add new OVS_DP_ATTR_IFINDEX for OVS_DP_CMD_NEW and use it as desired
ifindex.
Use OVS_VPORT_ATTR_IFINDEX during OVS_VPORT_CMD_NEW to specify new netdev
ifindex.

This driver always generated a random ethernet address. Leave it as a
fallback solution, but add a call to platform_get_ethdev_address().
Handle EPROBE_DEFER returned from platform_get_ethdev_address() to
retry when EEPROM is ready.

p0_mode set to one of the supported serial mode should not prevent
configuring the external SMI interface in
mv88e6xxx_g2_scratch_gpio_set_smi. The current masking of the p0_mode
only checks the first 2 bits. This results in switches supporting
serial mode cannot setup external SMI on certain serial modes
(Ex: 1000BASE-X and SGMII).
Extend the mask of the p0_mode to include the reduced modes and
serial modes as allowed modes for the external SMI interface.
