Stap failed to build the buildok/syscall.stp withthe following error
semantic error: unresolved target-symbol expression: identifier '$tvp'
at /usr/local/share/systemtap/tapset/syscalls2.stp:935:18
where tvp is an argument of sys_select
asmlinkage long sys_select(int n, fd_set __user *inp, fd_set __user *outp,
fd_set __user *exp, struct timeval __user *tvp)
This only happens on x86_64. Looks like a bug (elfutils or gcc).
In such reports please always cite the precise kernel build you are using.
If it's a kernel not built by Red Hat, please also cite the exact GCC
version used to build it (gcc rpm if it's an rpm).
Thanks,
Roland
