    sys/i386/i386        genassym.c 
    sys/i386/isa         ipl.s ipl_funcs.c 
    sys/kern             kern_lock.c kern_slaballoc.c

  Fix a number of interrupt related issues.
  * Don't access kernel_map in free(), defer such operations to malloc()
  * Fix a slab allocator panic due to mishandling of malloc size slab
    limit checks on machines with small amounts of memory (the slab allocator
    reduces the size of the zone on low-memory machines but did not handle the
    reduced size properly).
  * Add thread->td_nest_count to prevent splz recursions from underflowing
    the kernel stack.  This can occur because we drop the critical section
    when calling sched_ithd() in order to allow it to preempt.
  * Properly adjust intr_nesting_level around FAST interrupts
  * Adjust the debugging printf() in lockmgr to only complain about blockable
    lock requests from interrupts.
