That's an issue of the 2.6.26 ipipe patch. Philippe, you dropped the
nmi_32.h hunk:

diff --git a/include/asm-x86/nmi_32.h b/include/asm-x86/nmi_32.h

Should be merged into the unified nmi.h now.

George, in the meantime you can simply disable NMI watchdog support in
Xenomai, and then the build should succeed again.
