This patch adds some new header definitions from Linux 4.4: * MCL_ONFAULT is added to bits/mman.h / bits/mman-linux.h (this was already done for hppa). * PTRACE_SECCOMP_GET_FILTER is added to sys/ptrace.h. Along with it, the older PTRACE_GETSIGMASK and PTRACE_SETSIGMASK, added in Linux 3.11 but missed at the time, are also added. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * bits/mman-linux.h [!MCL_CURRENT] (MCL_ONFAULT): New macro. * sysdeps/unix/sysv/linux/alpha/bits/mman.h (MCL_ONFAULT): Likewise. * sysdeps/unix/sysv/linux/powerpc/bits/mman.h (MCL_ONFAULT): Likewise. * sysdeps/unix/sysv/linux/sparc/bits/mman.h (MCL_ONFAULT): Likewise. * sysdeps/unix/sysv/linux/sys/ptrace.h (PTRACE_GETSIGMASK): New enum constant and macro. (PTRACE_SETSIGMASK): Likewise. (PTRACE_SECCOMP_GET_FILTER): Likewise. * sysdeps/unix/sysv/linux/aarch64/sys/ptrace.h (PTRACE_GETSIGMASK): Likewise. (PTRACE_SETSIGMASK): Likewise. (PTRACE_SECCOMP_GET_FILTER): Likewise. * sysdeps/unix/sysv/linux/ia64/sys/ptrace.h (PTRACE_GETSIGMASK): Likewise. (PTRACE_SETSIGMASK): Likewise. (PTRACE_SECCOMP_GET_FILTER): Likewise. * sysdeps/unix/sysv/linux/powerpc/sys/ptrace.h (PTRACE_GETSIGMASK): Likewise. (PTRACE_SETSIGMASK): Likewise. (PTRACE_SECCOMP_GET_FILTER): Likewise. * sysdeps/unix/sysv/linux/s390/sys/ptrace.h (PTRACE_GETSIGMASK): Likewise. (PTRACE_SETSIGMASK): Likewise. (PTRACE_SECCOMP_GET_FILTER): Likewise. * sysdeps/unix/sysv/linux/sparc/sys/ptrace.h (PTRACE_GETSIGMASK): Likewise. (PTRACE_SETSIGMASK): Likewise. (PTRACE_SECCOMP_GET_FILTER): Likewise. * sysdeps/unix/sysv/linux/tile/sys/ptrace.h (PTRACE_GETSIGMASK): Likewise. (PTRACE_SETSIGMASK): Likewise. (PTRACE_SECCOMP_GET_FILTER): Likewise.
