 A single fix for the generic entry code:
 
   THe trace_sys_enter() tracepoint can modify the syscall number via
   kprobes or BPF in pt_regs, but that requires that the syscall number is
   re-evaluted from pt_regs after the tracepoint.
 
   A seccomp fix in that area removed the re-evaluation so the change does
   not take effect as the code just uses the locally cached number.
 
   Restore the original behaviour by re-evaluating the syscall number after
   the tracepoint.
