Alice Ryhl 5a78977262 mm: rust: make CONFIG_MMU ifdefs more narrow ... Currently the entire kernel::mm module is ifdef'd out when CONFIG_MMU=n. However, there are some downstream users of the module in rust/kernel/task.rs and rust/kernel/miscdevice.rs. Thus, update the cfgs so that only MmWithUserAsync is removed with CONFIG_MMU=n. The code is moved into a new file, since the #[cfg()] annotation otherwise has to be duplicated several times.
