so I complained about this when support for this went in for arm64.

Why do we have two separate ways of getting this info, one for x86 and one
for arm64/riscv?

Could we get x86 patched to use the same interface?

It's a pain for tool users to have to maintain multiple code paths because
the various architectures can't agree on how to export this info to
userspace.
