To pick the changes in these csets:
a49f4f81cb ("arch: Wire up Landlock syscalls")
2a1867219c ("fs: add mount_setattr()")
fa8b90070a ("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 addresses these perf build warnings:

Grab a copy of arch/mips/kernel/syscalls/syscall_n64.tbl and use it to
generate tools/perf/arch/mips/include/generated/asm/syscalls_n64.c file,
this is similar with commit 1b700c9975 ("perf tools: Build syscall
table .c header from kernel's syscall_64.tbl")

Map perf APIs (perf_reg_name/get_arch_regstr/unwind__arch_reg_id) with
MIPS specific registers.
[ayan@wavecomp.com: repick this patch for unwinding userstack backtrace
by perf and libunwind on MIPS based CPU.]
[yangtiezhu@loongson.cn: Add sample_reg_masks[] to fix build error,
silence some checkpatch errors and warnings, and also separate the
original patches into two parts (MIPS kernel and perf tools) to merge
easily.]
The original patches:
https://lore.kernel.org/patchwork/patch/1126521/https://lore.kernel.org/patchwork/patch/1126520/
Committer notes:
Do it as __perf_reg_name() to cope with:
067012974c ("perf tools: Fix arm64 build error with gcc-11")

perf currently fails to build on MIPS as there is no
tools/perf/arch/mips/Build file. Adding an empty file fixes this as
there are no MIPS-specific sources to build.
It looks like the same is needed for Alpha and PA-RISC, though I
haven't been able to test those.
