Remove NO_CANCELLATION macro
The NO_CANCELLATION macro is used currently on generic headers to define non cancellable syscalls and on Linux fcntl to implement the non cancellable variation. Former should be single-handled by not-cancel.h header and former could be simplified build both cancellable and non cancellable for default objects and alias the non-cancellable to default one for rtld ones (since Linux already support cancellation as default). This patch thus removes the NO_CANCELLATION macro and its usage. The generic non cancellable fcntl is route to internal fcntl. Checked on x86_64-linux-gnu and i686-linux-gnu. Also checked with a build again major ABIs. * sysdeps/generic/not-cancel.h (NO_CANCELLATION): Remove macro. * sysdeps/unix/sysv/linux/aarch64/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/alpha/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/arm/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/hppa/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/i386/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/ia64/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/m68k/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/microblaze/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/mips/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/nios2/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/powerpc/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/sh/sysdep-cancel.h (NO_CANCELLATION): Likewise * sysdeps/unix/sysv/linux/sparc/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/tile/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/x86_64/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/not-cancel.h (__fcntl_nocancel): Add hidden prototype. * sysdeps/unix/sysv/linux/fcntl.c (__fcntl_nocancel): Define only for !IS_IN (rtld) and remove NO_CANCELLATION usage.
