alpha: Use Linux generic sigaction implementation
Alpha rt_sigaction syscall uses a slight different kernel ABI than generic one: arch/alpha/kernel/signal.c 90 SYSCALL_DEFINE5(rt_sigaction, int, sig, const struct sigaction __user *, act, 91 struct sigaction __user *, oact, 92 size_t, sigsetsize, void __user *, restorer) Similar as sparc, the syscall expects a restorer function. However different than sparc, alpha defines the restorer as the 5th argument (sparc defines as the 4th). This patch removes the arch-specific alpha sigaction implementation, adapt the Linux generic one to different restore placements (through STUB macro), and make alpha use the Linux generic kernel_sigaction definition. Checked on alpha-linux-gnu and x86_64-linux-gnu (for sanity). * sysdeps/unix/sysv/linux/alpha/Makefile: Update comment about __syscall_rt_sigaction. * sysdeps/unix/sysv/linux/alpha/kernel_sigaction.h (kernel_sigaction): Use Linux generic defintion. (STUB): Define. (__syscall_rt_sigreturn, __syscall_sigreturn): Add prototype. * sysdeps/unix/sysv/linux/alpha/rt_sigaction.S (__syscall_rt_sigaction): Remove implementation. (__syscall_sigreturn, __syscall_rt_sigreturn): Define as global and hidden. * sysdeps/unix/sysv/linux/alpha/sigaction.c: Remove file. * sysdeps/unix/sysv/linux/alpha/sysdep.h (INLINE_SYSCALL, INTERNAL_SYSCALL): Remove definitions. * sysdeps/unix/sysv/linux/sigaction.c: Define STUB to accept both the action and signal set size. * sysdeps/unix/sysv/linux/sparc/sparc32/sigaction.c (STUB): Redefine. * sysdeps/unix/sysv/linux/sparc/sparc64/sigaction.c (STUB): Likewise.
