/*
 * entry.S contains the system-call and fault low-level handling routines.
 * This also contains the timer-interrupt handler, as well as all interrupts
 * and faults that can result in a task-switch.
 *
 * NOTE: This code handles signal-recognition, which happens every time
 * after a timer-interrupt and after each system call.
 *
 * I changed all the .align's to 4 (16 byte alignment), as that's faster
 * on a 486.
 *
 * Stack layout in 'ret_from_system_call':
 *      ptrace needs to have all regs on the stack.
 *      if the order here is changed, it needs to be 
 *      updated in fork.c:copy_process, signal.c:do_signal,
 *      ptrace.c and ptrace.h

   We want to spin without locking, and lock when we attempt an update.

   another CPU write invalidates our cache, and the lock is avoided when
   possible so we don't play ping-pong games with the cache line.
