Functions
void	syscall_save_restart_state (uint64_t nr, uint64_t a1, uint64_t a2, uint64_t a3, uint64_t a4, uint64_t a5, uint64_t a6)
void	syscall_init (void)
	Writes IA32_LSTAR MSR to the address of syscall_entry (the NASM entry stub in syscall.asm), writes IA32_STAR MSR with kernel CS (0x08) and user CS (0x1B) selectors, writes IA32_FMASK to mask IF during syscall entry (interrupts disabled at syscall boundary), and sets SCE bit in IA32_EFER. Called once by the BSP during boot.
void	syscall_get_saved_user_rdi_rsi_rdx (uint64_t out_rdi, uint64_t out_rsi, uint64_t *out_rdx)
	The SYSCALL instruction clobbers RCX and R11; arguments in RDI/RSI/RDX are preserved by the syscall.asm stub in per-CPU scratch space. This helper exposes them to kernel C code (e.g., SYS_execve handler) that needs all three argument registers.
