Ok, this seems to work and is what I'll sent to Linus.
commit 0c2d4569948a93fac01a17e191ede4f754607a4a
Author: David S. Miller <[email protected]>
Date: Mon Oct 2 14:17:57 2006 -0700
[SPARC64]: Move signal compat bits to new header file.
Create asm-sparc64/compat_signal.h and stuff things there.
This avoids the "linux/compat.h includes asm/signal.h but
asm/signal.h needs compat_sigset_t which isn't defined yet"
problems introduced recently.
