tools headers: Update the syscall tables and unistd.h, mostly to support the new 'mseal' syscall
But also to wire up shadow stacks on 32-bit x86, picking up those changes from these csets:ff388fe5c4
("mseal: wire up mseal syscall")2883f01ec3
("x86/shstk: Enable shadow stacks for x32") This makes 'perf trace' support it, now its possible, for instance to do: # perf trace -e mseal --max-stack=16 Here is an example with the 'sendmmsg' syscall: root@x1:~# perf trace -e sendmmsg --max-stack 16 --max-events=1 0.000 ( 0.062 ms): dbus-broker/1012 sendmmsg(fd: 150, mmsg: 0x7ffef57cca50, vlen: 1, flags: DONTWAIT|NOSIGNAL) = 1 syscall_exit_to_user_mode_prepare ([kernel.kallsyms]) syscall_exit_to_user_mode_prepare ([kernel.kallsyms]) syscall_exit_to_user_mode ([kernel.kallsyms]) do_syscall_64 ([kernel.kallsyms]) entry_SYSCALL_64 ([kernel.kallsyms]) [0x117ce7] (/usr/lib64/libc.so.6 (deleted)) root@x1:~# To do a system wide tracing of the new 'mseal' syscall with a backtrace of at most 16 entries.
