Conceptually:

I also have to admit to being somewhat skeptical to the concept on a
littleendian architecture like x86.

Code-wise:

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

As such, your claim that the changes are not intrusive is plain false.
