The proc-empty-vm test is implemented for x86_64 and fails to build for other architectures. Rather then emitting a compiler error it would be preferable to only build the test on supported architectures.

Ehh, can you just port it to whatever arch you're using? What's the address space on arm/arm64?

#ifdef __amd64__ munmap(NULL, ((size_t)1 << 47) - 4096); #else #error "implement 'unmap everything'" #endif

This program is almost arch-independent.
