7ad8c6a6d2 Shared library done in a formal way (using auxv). Now kernel loads both loader and program. 
Known issues: not compatible with musl's reclaim_gaps (crash on __malloc_donate). Removing reclaim makes hello world work.

7b8252eb1b Basic loadable kernel module support, with a module template written in Rust. 
Under aarch64 and x86_64, hello_rust can be built and loaded by `/busybox insmod hello_rust.ko`.

da028c1f10 Added virtual memory support for aarch64 and x86_64. 
1. Memory mapping at KSEG2_START(0xffff_fe80_0000_0000) will now be visible to all processes.
   This feature is required by Loadable Kernel Module when mapping kernel module into memory.
2. Wrapping PageTableImpl::active() into ManuallyDrop, so that no extra "mem::forget" is required.
3. Added PageTableImpl::kernel_table(). This function is the same as active() on x86_64, but not the same on aarch64.
