13 * entry.S contains the system-call and fault low-level handling routines.
14 * This also contains the timer-interrupt handler, as well as all interrupts
15 * and faults that can result in a task-switch.
17 * NOTE: This code handles signal-recognition, which happens every time
18 * after a timer-interrupt and after each system call.
20 * Stack layout in 'ret_from_system_call':
21 * ptrace needs to have all regs on the stack.
22 * if the order here is changed, it needs to be
23 * updated in fork.c:copy_process, signal.c:do_signal,
24 * ptrace.c and ptrace.h
