i'd suggest to add an ARCH_ILLEGAL_POINTER define instead, which defaults to zero and gets added to pointer-ish poison values. That makes it both simpler and also it does not need any include/asm changes because ARCH_ILLEGAL_POINTER can be set from the Kconfig space.

Any idea how to override a value in Kconfig? We can do it for bool values but not strings.


default 0

config X86
select ILLEGAL_POINTER_VALUE=0x80000000000000000000000000 if X86_64


I could do it with a boolean signifying existence and a hex for the value, but I'd rather not.
