this patch add a direct call to shmget syscall if it is supported by kernel features. Checked on x86_64, i686, powerpc64le, aarch64, and armhf. * sysdeps/unix/sysv/linux/alpha/syscalls.list (shmget): Remove. * sysdeps/unix/sysv/linux/arm/syscalls.list (shmget): Likewise. * sysdeps/unix/sysv/linux/generic/syscalls.list (shmget): Likewise. * sysdeps/unix/sysv/linux/hppa/syscalls.list (shmget): Likewise. * sysdeps/unix/sysv/linux/ia64/syscalls.list (shmget): Likewise. * sysdeps/unix/sysv/linux/microblaze/syscalls.list (shmget): Likewise. * sysdeps/unix/sysv/linux/mips/mips64/syscalls.list (shmget): Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/syscalls.list (shmget): Likewise. * sysdeps/unix/sysv/linux/x86_64/syscalls.list (shmget): Likewise. * sysdeps/unix/sysv/linux/shmget.c (shmget): Use shmget syscall if it is defined. |

This hierarchy supports Linux systems using the new asm-generic/unistd.h, which removes many familiar old syscalls. For example, to implement open(), newer Linux architectures require glibc to invoke the __NR_openat syscall with AT_FDCWD. This hierarchy provides all those implementations. It also provides support for 32-bit platforms using the 64-bit kernel syscall APIs, as the 32-bit ones are no longer provided. Note that newer ILP32 environments (x32 or AArch64:ILP32, for example) are converting to use more 64-bit types in kernel syscalls, so that aspect of this support is in more flux as of this writing.
