ourselves.

d2397ac5f7 completely remove Mach VM support. all that is left is the all the 
header files as UVM still uses (most of) these.

006ee23e99 Fix another problem is the modified bit emulation that caused double faults. 
We need to set the L2 type preemptively, as it may still be L2_INVAL if the
page had not been previously accessed.

76fa1751fe Add a macro to check for sufficient pointer alignment in bus.h context, 
"BUS_SPACE_ALIGNED_POINTER()".
Equal to the param.h "ALIGNED_POINTER()" normally, but obeys additional
requirements of the bus_space_xxx_n() macros. (BUS_SPACE_DEBUG)

5f63cab877 The page and section fault handling paths are essentially identical, so 
combine them.  This also fixes a performance issue, in that we always
faulted pages twice in order to write them.

79e56d3237 The ARM has the same copy-on-write bug as the i386 -- the write enable bit in 
PTEs is ignored when in kernel mode.  Hack around this just like we do on the
i386, by adding a prepass to copyout() to check for write permission on the
destination pages.

8f3d31a32b More cleanup... 
* Don't bother pulling PT_M and PT_H bits from pv_flags; they can't ever be
  set there!
* Actually make pmap_clear_reference() do something useful.
* Also set the referenced bit (PT_H) when emulating a write fault.

da99fe308e Repeat after me: 
If we're doing modified bit emulation, we must revoke write permission in
pmap_clear_modify().  This is non-negotiable.  I will revoke write permission
in pmap_clear_modify(), or suffer the wrath of a thousand bricks.

3c8512dbb5 We could not possibly have been updating the pv attributed correctly in 
pmap_enter(), so... make the obvious change.

the problem these bug reports described is fixed and they are closed.

34a92d6f82 Fix addressing problem for the aux status register. Whilst reads of this 
read appear to be aliased in the address space, writes are not thus the
correct address is important in order to reset drives.
