* sysdeps/unix/sysv/linux/fcntl.c (__fcntl_nocancel): Remove static inline __attribute ((always_inline)). Don't define if NO_CANCELLATION. (__libc_fcntl): Use INLINE_SYSCALL directly instead of __fcntl_nocancel. * sysdeps/unix/sysv/linux/powerpc/powerpc64/fcntl.c (__fcntl_nocancel): Remove static inline __attribute ((always_inline)). Don't define if NO_CANCELLATION. (__libc_fcntl): Use INLINE_SYSCALL directly instead of __fcntl_nocancel. * sysdeps/unix/sysv/linux/i386/fcntl.c (__fcntl_nocancel): Define to __libc_fcntl if NO_CANCELLATION and __ASSUME_FCNTL64 == 0. Don't define at all if NO_CANCELLATION and __ASSUME_FCNTL64 > 0. (__libc_fcntl): Don't define if __fcntl_nocancel is a macro.
