[PATCH] ARM: Use SYSCALL_DEFINEx for sys_sigreturn and sys_rt_sigreturn

[PATCH] ARM: Use SYSCALL_DEFINEx for sys_sigreturn and sys_rt_sigreturn

[Jan Glauber]

Use the SYSCALL_DEFINEx macros to declare the system calls sigreturn
and rt_sigreturn. This enables system call tracing which is only
available in the SYSCALL_DEFINEx macros.
