Hmm, is it OK for code to check against compiler provided macros (see
below) instead of relying on MACHINE (or whatever kernel-provided value
appropriate)? Maybe param.h should provide valid definition of btop/
ptopb (it does define {arm,sh3,sh5,mips}_[pb]to[bp], so another two
#defines would do)?

This macro is defined by the compiler:

	/data/tools/lib/gcc-lib/arm--netbsdelf/2.95.3/specs:-D__arm__
	-D__NetBSD__ -D__ELF__ -Asystem(unix) -Asystem(NetBSD) -Acpu(arm)
	-Amachine(arm)

How are you building the kernel? I'm not able to reproduce the error.
I'm going to test against fresh -current checkout (which will take some
time on my line ;).

	Have a nice day,
