> + * Subject: Avoid using asm/procinfo.h
> +
> +I previously noted
> +<http://sourceware.org/ml/libc-ports/2006-08/msg00023.html> that the
> +use of <asm/procinfo.h>, a Linux-specific kernel header, in
> +sysdeps/arm/eabi, is an abstraction violation, and that in principle
> +all the files in sysdeps/arm/eabi should use sysdep.h not
> +asm/procinfo.h for HWCAP_VFP.
> +
> +The ARM kernel maintainers have now declared that <asm/procinfo.h>
> +should not be used outside the kernel at all (and in particular that
> +headers_install is correct in not exporting it), and that these
> +definitions will move to a different kernel header. This gives a
> +concrete reason for making the change to use glibc's internal
> +definitions, which this patch does, thereby allowing glibc to build
> +with the exported headers.
