headers_check is not broken, headers_install is.

Hmm, in some sense headers_check _is_ broken, as it doesn't notice
headers_install
installs headers that refer to other headers that are not installed...

Yep, it's a regression from 2.6.28.

Greg, I had a quick look at your signcontext.h and signal.h merge, and the MMU
part seems to be OK.

However, some of the installed headers still have checks for CONFIG_MMU:

param.h:#ifdef CONFIG_MMU
sigcontext.h:#ifndef CONFIG_MMU
sigcontext.h:#ifdef CONFIG_MMU
siginfo.h:#ifdef CONFIG_MMU
siginfo.h:#ifdef CONFIG_MMU
siginfo.h:#endif /* CONFIG_MMU */
swab.h:#elif defined(CONFIG_MMU)

so these have to be added to the generic unifdef-y list (is that
include/asm-generic/Kbuild.asm?).

Gr{oetje,eeting}s,
