Ruihan Li 9d5e889a93 Implement `VmIo` for `CurrentUserspace` 2025-12-07 12:01:05 +08:00
zjp c9302471e8 Make some boot entry functions unsafe and document safety 
The following functions are unsafe now:
- riscv_boot
- loongarch_boot
- ap_early_entry
- kernel_task_entry

Remove extern declaration of ap_early_entry from riscv_ap_early_entry
And
- Directly call ap_early_entry from module path.
- Clarify what safety requirements are on riscv_ap_early_entry
- Clarify how safety requirements are met on calling ap_early_entry
