Annotating the global Documentation/Changes with every per-arch
requirement... not sure that's the right place for it.
It doesn't matter to me where it's documented in the kernel
documentation, but we should document it.
And we should expect folks who post patches with new toolchain
constraints to also send patches for that documentation...
Noting armv7 requirements in
an arm-specific file makes sense. Annotating the top level one raises
the question of why not to do that for arc, unicore, openrisc, tile...
Yes - it's the following x86-specific text in Documentation/Changes that
inspired the patch:
-----
Linux on IA-32 has recently switched from using as86 to using gas for
assembling the 16-bit boot code, removing the need for as86 to compile
your kernel. This change does, however, mean that you need a recent
release of binutils.

But we can move that to Documentation/x86/ also.
regards,
- Paul
