This fixes a bug where a binary linked using max-page-size=0x200000 can result in a bogus relocation offset when running on a system with a smaller page size. This causes samples to fall outside the image mapping or be translated to the wrong address (resulting in symbol resolution, or incorrect symbol resolution). We noticed this at Netflix because we run a patchset enabling 16k pages on amd64 and have been compiling userspace with a 2MB page size. Since we started doing this profiling userspace binaries has been wonky. Reviewed by: ali_mashtizadeh.com Differential Revision: https://reviews.freebsd.org/D59771 Sponsored by: Netflix
