We used libaudit to map ids to syscall names and vice-versa, but that
imposes a delay in supporting new syscalls, having to wait for libaudit
to get those new syscalls on its tables.
To remove that delay, for x86_64 initially, grab a copy of
arch/x86/entry/syscalls/syscall_64.tbl and use it to generate those
tables.
Syscalls currently not available in audit-libs:
# trace -e
copy_file_range,membarrier,mlock2,pread64,pwrite64,timerfd_create,userfaultfd
Error: Invalid syscall copy_file_range, membarrier, mlock2, pread64,
pwrite64, timerfd_create, userfaultfd
Hint: try 'perf list syscalls:sys_enter_*'
Hint: and: 'man syscalls'
#
With this patch:
# trace -e

There is racing in Makefile. I see following output:

The error disappeareafter doing 'make archheaders' before 'make all'.
Thank you.
