FWIW, there's an m68knommu counterpart (ACKed by gerg a while ago).  The
entire bunch is on ftp.linux.org.uk/pub/people/viro/m68k-signals - both m68k
and m68knommu sets.  I don't know how you guys would prefer it done, since
there's a trivial dependency between m68k and m68knommu parts of series -
the former has
+#ifndef __uClinux__
+#define __ARCH_WANT_SYS_RT_SIGSUSPEND
+#endif
in unistd.h and the latter does
-#ifndef __uClinux__
 #define __ARCH_WANT_SYS_RT_SIGSUSPEND
-#endif
Both parts switch to generic sys_rt_sigsuspend(), for mmu and nommu resp.,
so they need __ARCH_WANT_SYS_RT_SIGSUSPEND defined as soon as conversion
is done.  Other than that they are independent.
