Pull core entry fix from Thomas Gleixner:
"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"
