[MIPS] signal: do not use save_static_function() anymore
This macro was used to save static registers before calling sys_sigsuspend() and sys_sigreturn(). For the sys_sigreturn() case, there's no point to save them since they have been already saved by setup_sigcontext() before calling the signal handler. For the sys_sigsuspend() case, I don't see any reasons... Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
