To pick the changes in these csets:
a49f4f81cb48925e ("arch: Wire up Landlock syscalls")
2a1867219c7b27f9 ("fs: add mount_setattr()")
fa8b90070a80bb1a ("quota: wire up quotactl_path")
That silences these perf build warnings and add support for those new
syscalls in tools such as 'perf trace'.
For instance, this is now possible:
# ~acme/bin/perf trace -v -e landlock*
event qualifier tracepoint filter: (common_pid != 129365 && common_pid != 3502) && (id == 444 || id == 445 || id == 446)
^C#
That is tha filter expression attached to the raw_syscalls:sys_{enter,exit}
tracepoints.
$ grep landlock tools/perf/arch/x86/entry/syscalls/syscall_64.tbl
444 common landlock_create_ruleset sys_landlock_create_ruleset
445 common landlock_add_rule sys_landlock_add_rule
446 common landlock_restrict_self sys_landlock_restrict_self
$

This adds this new syscall to the tables used by tools such as 'perf

Pull compat mount cleanups from Al Viro:
"The last remnants of mount(2) compat buried by Christoph.
Buried into NFS, that is.
Generally I'm less enthusiastic about "let's use in_compat_syscall()
deep in call chain" kind of approach than Christoph seems to be, but
in this case it's warranted - that had been an NFS-specific wart,
hopefully not to be repeated in any other filesystems (read: any new
filesystem introducing non-text mount options will get NAKed even if
it doesn't mess the layout up).
IOW, not worth trying to grow an infrastructure that would avoid that
use of in_compat_syscall()..."
* 'compat.mount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
fs: remove compat_sys_mount

Since commit 61a47c1ad3a4dc ("sysctl: Remove the sysctl system call"),
sys_sysctl is actually unavailable: any input can only return an error.
We have been warning about people using the sysctl system call for years
and believe there are no more users. Even if there are users of this
interface if they have not complained or fixed their code by now they
probably are not going to, so there is no point in warning them any
longer.
So completely remove sys_sysctl on all architectures.

Now that the ->compat_{get,set}sockopt proto_ops methods are gone
there is no good reason left to keep the compat syscalls separate.
This fixes the odd use of unsigned int for the compat_setsockopt
optlen and the missing sock_use_custom_sol_socket.
It would also easily allow running the eBPF hooks for the compat
syscalls, but such a large change in behavior does not belong into
a consolidation patch like this one.

Copy over powerpc syscall.tbl to grab changes from the below commits
fddb5d430ad9 ("open: introduce openat2(2) syscall")
9a2cef09c801 ("arch: wire up pidfd_getfd syscall")
Now 'perf trace' on powerpc will be able to map from those syscall
strings to the right syscall numbers, i.e.
perf trace -e pidfd*
Will include 'pidfd_getfd' as well as:
perf trace open*
Will cover all 'open' variants.
