no extra compat wrappers needed.

a274bd498c sparc: switch to use of generic old sigaction 
note that due to historical accident we do *not* directly take
generic versions - need to check and invert the sign of signal
number first.

bdc40abf07 sparc: switch sys_compat_rt_sigaction() to COMPAT_SYSCALL_DEFINE 
note that while struct compat_sigaction is the generic one, syscall
itself *isn't* - different arguments.  IOW, CONFIG_ODD_RT_SIGACTION
stays.

50150d2bb9 mips: switch to generic sys_fork() and sys_clone() 
we still need the wrappers to store callee-saved registers in
pt_regs, but once that done we can jump to kernel/fork.c variants.

bde208d2e1 switch mips to generic rt_sigsuspend(), make it unconditional 
mips was the last architecture not using the generic variant.
Both native and compat variants switched to generic, which is
made unconditional now.
