4daebcbff5 Make the imask_t typedef a struct rather than a naked array. The attribute 
on the array typedef was contaminating other u_int32_t naked arrays and
affecting their alignment.

2f9404413f If extracting an address from the kernel pmap, see if the address is outside 
the mapped address range.  If so, try to look it up via the BAT table.  If
successful, translate and return the BAT'ed pa.

a pointer to current cpu's cpu_info structure.  Use cpu_info for
intstk,intr_depth,still_stk,idle_pcb,curpcb,curlwp,etal even on
non-MULTIPROCESSOR machines.  Add common macros GET_CPUINFO and
INIT_CPUINFO to get and initialize the cpu_info struct on startup.  Make
ibm4xx use the standard <powerpc/frame.h>.  Use IFRAME_xx in ibm4xx
trap_subr.S instead of explicit magic offsets.  Move INTSTK and SPILLSTK
to std.<platform>.  Change faultbuf to a struct instead of an array.

On MPC6XX cpus, stop using the vector page for temporary space and use
reserved space in cpu_info.

f464631d66 Several things: 
1) rights should be shared by the threads within a process. While it would
be easier to handle this with the struct proc/struct lwp split, we attempt to
do this now by sharing the right lists. Because each right holds a reference
to struct proc, this might cause some problems later.
2) in pthread_exit, really exit the thread. Also reintialize the righ tlist to
make sure we will not destroy the parent's right list
3) rights can hold multiple permissions on a port (ie: send and receive). Fix th
is.
4) first attempt on right carried by messages. We still have to do rights carrie
d in the message body (complex messages).

function provided to fork1(). The child function is machine dependent and
is not yet implemented for i386.

9f6565f2bd A working fork/vfork implementation. Darwin fork differs from our fork by 
two ways:
- the child gets its pid as retval[0] (userland stub will turn it into a 0),
retval[1] is 1 and it is 0 in the parent.
- in the child, the fork syscall is successful, hence we must skip the next
instruction.

4017fd1809 fix two bugs in the previous PTE-spill handling changes: 
- in pmap_pte_spill(), the victim PTE could be using the secondary hash,
   in which case its pvo entry is actually in the other bucket.  use the
   correct bucket for the victim pvo when moving it to the front of its list.
 - similarly, in pmap_pvo_remove(), if the pteidx is pre-computed for us,
   it might actually point to the other bucket if the entry is using the
   secondary hash.  adjust ptegidx if this is the case.

these should fix PRs 18645 and 18736.
