Code-wise:

The code is horrific; it is full of open-coded magic numbers;

Agreed, the magic needs macro definition and comments.

it also
puts a function called arch_get_unmapped_exec_area() in a generic file,
which could best be described as "WTF" -- the arch_ prefix we use
specifically to denote a per-architecture hook function.

Agreed.  But I'd want to leave it in mm/mmap.c as it's likely be used by
other archs - the changes are bitness specific, not arch specific.  Is
it OK if I do this?

#ifndef HAVE_ARCH_UNMAPPED_EXEC_AREA
void *arch_get_unmapped_exec_area(...)
{
    ...
}
#endif

Only if this is really an architecture-specific function overridden in
specific architectures.  I'm not so sure that applies here.
Furthermore, I'm not even all that sure what this function *does*.
