timer-interrupt handler, as well as all interrupts 10 * and faults that can result in a task-switch. 11 * 12 * NOTE: This code handles signal-recognition, which happens every time 13 * after a timer-interrupt and after each system call. 14 * 15 * I changed all the .align's to 4 (16 byte alignment), as that's faster 16 * on a 486. 17 * 18 * Stack layout in 'ret_from_system_call': 19 * ptrace needs to have all regs on the stack. 20 * if the order here is changed, it needs to be 21 * updated in fork.c:copy_process, signal.c:do_signal, 22 * ptrace.c and ptrace.h 23 * 24 * 0(%esp) - %ebx 25 *
