Summary of changes: - kernel/mem renamed to kernel/mm - consolidated page/frame defs into one file which now lives in the kernel/mm package and is referenced by both pmm and vmm pkgs - consolidated parts of the vmm code (e.g. PDT+PTE) - memcopy/memset helpers moved to the kernel package - physical allocators moved to the kernel/mm/pmm package - break vmm -> pmm pkg dependency by moving AllocFrame() into the mm package.
