3.16.36-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: "Dmitry V. Levin" <[email protected]> commit f0b22d1bb2a37a665a969e95785c75a4f49d1499 upstream. Do not load one entry beyond the end of the syscall table when the syscall number of a traced process equals to __NR_Linux_syscalls. Similar bug with regular processes was fixed by commit 3bb457af4fa8 ("[PARISC] Fix bug when syscall nr is __NR_Linux_syscalls"). This bug was found by strace test suite. Signed-off-by: Dmitry V.
