Functions
void	syscall_entry (void)
	Assembly entry point for syscalls.
void	syscall_ctx_init (syscall_ctx_t *ctx, stack_pointer_t *kernelStack)
	Initialize a per-thread syscall context.
void	syscall_ctx_load (syscall_ctx_t *ctx)
	Load a syscall context into the CPU.
void	syscall_table_init (void)
	Initialize the syscall table.
void	syscalls_cpu_init (void)
	Initalize syscalls on the current CPU.
uint64_t	syscall_handler (uint64_t rdi, uint64_t rsi, uint64_t rdx, uint64_t rcx, uint64_t r8, uint64_t r9, uint64_t number)
	C syscall handler.

Variables
