Andrew Boie 3d80208025 x86: implement user mode on 64-bit ... - In early boot, enable the syscall instruction and set up necessary MSRs - Add a hook to update page tables on context switch - Properly initialize thread based on whether it will start in user or supervisor mode - Add landing function for system calls to execute the desired handler - Implement arch_user_string_nlen() - Implement logic for dropping a thread down to user mode - Reserve per-CPU storage space for user and privilege elevation stack pointers, necessary for handling syscalls when no free registers are available - Proper handling of gs register considerations when transitioning privilege levels Kernel page table isolation (KPTI) is not yet implemented.
