switching to newer linux-libc-dev linux-2.6 provided kernel
headers worked fine beside on mips mipsel:
In file included from usr/klibc/arch/mips/crt0.S:11:
usr/include/arch/mips/machine/asm.h:8:24: error: asm/regdef.h: No such
file or directory
usr/include/arch/mips/machine/asm.h:9:21: error: asm/asm.h: No such file
or directory
i'm not sure if you want to export both headers in the make
kernelheaders target or if it is the fault of klibc to assume
that those are available?

If I remember correctly (sorry, I'm on the road at the moment), those
files should be exportable. They wouldn't be all that hard to replicate
in klibc, though.

Both headers contain cpp macros for assembly code to work with the
mariads of mips ABIs. I don't think the kernel should export those
headers. And yes, they're both quite trivial.

<asm/asm.h> would need to add __KERNEL__ wrappers around the CONFIG_* bits.
In addition you probably want to have <asm/fpregdef.h> exported. With a
few changes you should be able to get away without using <asm/sgidefs.h>.

Oh, the canonical place for these headers outside the kernel is either
<{regdef,fpregdef,asm}.h> and <sys/{regdef,fpregdef,asm}.h>, not <asm/...>.

Well, yes, but klibc implements a lot of headers by #including
appropriate kernel bits.
