Do you mean that on arm64 PIC vs. non-PIC differences are less radical? Or there's no interest in building [parts of] the kernel with -fPIE for arm64? > No there is not. I was referring to arm64 before, where non-PIC codegen is > actually better for us than PIC codegen, because it omits all the GOT stuff > and other things that are only relevant to shared libraries in user space > (symbol preemption, reducing the CoW footprint of writable segments, etc) I still find myself confused, because non-PIC is going to be more efficient everywhere for the same reasons, not just on arm64.
