For hybrid metrics it is useful to know the number of p-core or e-core
CPUs. If a cpumask is specified for the num_cpus or num_cpus_online
tool events, compute the value relative to the given mask rather than
for the full system.
```
$ sudo /tmp/perf/perf stat -e 'tool/num_cpus/,tool/num_cpus,cpu=cpu_core/,

On hybrid systems, events like msr/tsc/ will aggregate counts across
all CPUs. Often metrics only want a value like msr/tsc/ for the cores
on which the metric is being computed. Listing each CPU with terms
cpu=0,cpu=1.. is laborious and would need to be encoded for all
variations of a CPU model.
Allow the cpumask from a PMU to be an argument to the cpu term. For
example in the following the cpumask of the cstate_pkg PMU selects the
CPUs to count msr/tsc/ counter upon:
```
$ cat /sys/bus/event_source/devices/cstate_pkg/cpumask
0
$ perf stat -A -e 'msr/tsc,cpu=cstate_pkg/' -a sleep 0.1
Performance counter stats for 'system wide':
CPU0 252,621,253 msr/tsc,cpu=cstate_pkg/
0.101184092 seconds time elapsed
```
As the cpu term is now also allowed to be a string, allow it to encode
a range of CPUs (a list can't be supported as ',' is already a special
token).
The "event qualifiers" section of the `perf list` man page is updated
to detail the additional behavior. The man page formatting is tidied
up in this section, as it was incorrectly appearing within the
"parameterized events" section.

Leave device specific adminq commands in separate folders. This lead to
a change that need to be done in filling/getting descriptor:

cmd = &desc.params.specific_desc;
- now: struct specific_desc *cmd;
cmd = libie_aq_raw(&desc);
Do this changes across the driver to allow clean build. The casting only
have to be done in case of specific descriptors, for generic one union
can still be used.
Changes beside code moving:
- change ICE_ prefix to LIBIE_ prefix (ice_ and libie_ too)
- remove shift variables not otherwise needed (in libie_aq_flags)
- fill/get descriptor data based on desc.params.raw whenever the
descriptor isn't defined in libie
- move defines from the libie_aq_sth structure outside
- add libie_aq_raw helper and use it instead of explicit casting

The function ksmbd_vfs_kern_path_locked() seems to serve two functions
and as a result has an odd interface.
On success it returns with the parent directory locked and with write
access on that filesystem requested, but it may have crossed over a
mount point to return the path, which makes the lock and the write
access irrelevant.
This patches separates the functionality into two functions:
- ksmbd_vfs_kern_path() does not lock the parent, does not request
write access, but does cross mount points
- ksmbd_vfs_kern_path_locked() does not cross mount points but
does lock the parent and request write access.
The parent_path parameter is no longer needed. For the _locked case
the final path is sufficient to drop write access and to unlock the
parent (using path->dentry->d_parent which is safe while the lock is
held).
There were 3 caller of ksmbd_vfs_kern_path_locked().
- smb2_create_link() needs to remove the target if it existed and
needs the lock and the write-access, so it continues to use
ksmbd_vfs_kern_path_locked(). It would not make sense to
cross mount points in this case.
- smb2_open() is the only user that needs to cross mount points
and it has no need for the lock or write access, so it now uses
ksmbd_vfs_kern_path()
- smb2_creat() does not need to cross mountpoints as it is accessing
a file that it has just created on *this* filesystem. But also it
does not need the lock or write access because by the time
ksmbd_vfs_kern_path_locked() was called it has already created the
file. So it could use either interface. It is simplest to use
ksmbd_vfs_kern_path().
ksmbd_vfs_kern_path_unlock() is still needed after
ksmbd_vfs_kern_path_locked() but it doesn't require the parent_path any
more. After a successful call to ksmbd_vfs_kern_path(), only path_put()
is needed to release the path.

"Two important arm64 fixes ahead of the 6.16 release.
The first fixes a regression introduced during the merge window where
the KVM UUID (which is used to advertise KVM-specific hypercalls for
things like time synchronisation in the guest) was corrupted thanks to
an endianness bug introduced when converting the code to use the
UUID_INIT() helper.
The second fixes a stack-pointer corruption issue during
context-switch which has been observed in the wild when taking a
pseudo-NMI with shadow call stack enabled.

Merge tag 'net-6.16-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Paolo Abeni:
"Including fixes from can and xfrm.
The TI regression notified last week is actually on our net-next tree,
it does not affect 6.16.
We are investigating a virtio regression which is quite hard to
reproduce - currently only our CI sporadically hits it. Hopefully it
should not be critical, and I'm not sure that an additional week would
be enough to solve it.
Current release - fix to a fix:
- sched: sch_qfq: avoid sleeping in atomic context in qfq_delete_class
Previous releases - regressions:
- xfrm:
- set transport header to fix UDP GRO handling
- delete x->tunnel as we delete x
- eth:
- mlx5: fix memory leak in cmd_exec()
- i40e: when removing VF MAC filters, avoid losing PF-set MAC
- gve: fix stuck TX queue for DQ queue format

ri_buf just holds a pointer/len pair and is not a log iovec used for
writing to the log. Switch to use a kvec instead.

The lv_size member counts the size of the entire allocation, rename it to
lv_alloc_size to make that clear.
The lv_buf_len member tracks how much of lv_buf has been used up
to format the log item, rename it to lv_buf_used to make that more clear.

By the time xfs_cil_prepare_item is called, the old lv is still pointed
to by the log item. Take it from there instead of spreading the old lv
logic over xlog_cil_insert_format_items and xfs_cil_prepare_item.

Replace the deprecated strncpy() with memtostr_pad(). This also avoids
the need for separate zeroing using memset(). Mark sb_fname buffer with
__nonstring as its size is XFSLABEL_MAX and so no terminating NULL for
sb_fname.
