sorry, what does "clean tree" mean?
i just make menuconfig in l4linux-2.6/ and then make it.
by the way, i want to ask :
the "L4 tree build directory" option in l4linux menuconfig should be
pointed to "the output directory of l4env" or "the output directory of fiasco" or both?

This is ok.
Is there a file include/asm/generic/irq.h in your tree? That's where
L4_IRQ_DISABLED should be defined.
yes there is.
i have tried to test the code ( include/asm-l4/l4-arch/asm/irqflags.h ),
and find the first #ifndef __ASSAMBLY__ is NOT fulfill, so it doesn't include the file
file include/asm/generic/irq.h, but the second #ifndef __ASSAMBLY__ is fulfill...
it's so strange.
