Summary

Replace pointer members of structs u_resource and u_rman to kvaddr_t.
These structs exported to userspace, but the members never used as pointers in userspace (but instead used as unique idenitifiers).

These breaks a bit of ABI but we believe that only libdevinfo uses it (?).

br created this revision.

Motivation is so the sysctl works for non-native ABIs.

Justification for the ABI break is I can't find any references to the structs via code search.debian.net, libdevinfo is the only in-tree consumer and it only affects 32-bit architectures.
