Adhemerval Zanella 2c1903cbba sparc: Fix restartable syscalls (BZ 32173)
The commit 'sparc: Use Linux kABI for syscall return'
(86c5d2cf0c) did not take into account
a subtle sparc syscall kABI constraint.  For syscalls that might block
indefinitely, on an interrupt (like SIGCONT) the kernel will set the
instruction pointer to just before the syscall:

arch/sparc/kernel/signal_64.c
476 static void do_signal(struct pt_regs *regs, unsigned long orig_i0)
477 {
[...]
525                 if (restart_syscall) {
526                         switch (regs->u_regs[UREG_I0]) {
527                         case ERESTARTNOHAND:
528                         case ERESTARTSYS:
529                         case ERESTARTNOINTR:
530                                 /* replay the system call when we are done */
531                                 regs->u_regs[UREG_I0] = orig_i0;
532                                 regs->tpc -= 4;
533                                 regs->tnpc -= 4;
534                                 pt_regs_clear_syscall(regs);
535                                 fallthrough;
536                         case ERESTART_RESTARTBLOCK:
537                                 regs->u_regs[UREG_G1] = __NR_restart_syscall;
538                                 regs->tpc -= 4;
539                                 regs->tnpc -= 4;
540                                 pt_regs_clear_syscall(regs);
541                         }

However, on a SIGCONT it seems that 'g1' register is being clobbered after the
syscall returns.  Before 86c5d2cf0c, the 'g1' was always placed jus
before the 'ta' instruction which then reloads the syscall number and restarts
the syscall.

On master, where 'g1' might be placed before 'ta':

  $ cat test.c
  #include <unistd.h>

  int main ()
  {
    pause ();
  }
  $ gcc test.c -o test
  $ strace -f ./t
  [...]
  ppoll(NULL, 0, NULL, NULL, 0

On another terminal

  $ kill -STOP 2262828

  $ strace -f ./t
  [...]
  --- SIGSTOP {si_signo=SIGSTOP, si_code=SI_USER, si_pid=2521813, si_uid=8289} ---
  --- stopped by SIGSTOP ---

And then

  $ kill -CONT 2262828

Results in:

  --- SIGCONT {si_signo=SIGCONT, si_code=SI_USER, si_pid=2521813, si_uid=8289} ---
  restart_syscall(<... resuming interrupted ppoll ...>) = -1 EINTR (Interrupted system call)

Where the expected behaviour would be:

  $ strace -f ./t
  [...]
  ppoll(NULL, 0, NULL, NULL, 0)           = ? ERESTARTNOHAND (To be restarted if no handler)
  --- SIGSTOP {si_signo=SIGSTOP, si_code=SI_USER, si_pid=2521813, si_uid=8289} ---
  --- stopped by SIGSTOP ---
  --- SIGCONT {si_signo=SIGCONT, si_code=SI_USER, si_pid=2521813, si_uid=8289} ---
  ppoll(NULL, 0, NULL, NULL, 0

Just moving the 'g1' setting near the syscall asm is not suffice,
the compiler might optimize it away (as I saw on cancellation.c by
trying this fix).  Instead, I have change the inline asm to put the
'g1' setup in ithe asm block.  This would require to change the asm
constraint for INTERNAL_SYSCALL_NCS, since the syscall number is not
constant.

Checked on sparc64-linux-gnu.
