9639d2bb98 modify udv_attach() and its caller (uvm_mmap()) so that it's passed the 
offset and size of the requested region to be mapped, so that the
udv_attach() can use the device d_mmap() entry to check mappability
of the requested region.

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.

0074502b0a o Add bootinfo support by checking the fifth and sixth arguments for a 
magic number and a pointer to the bootinfo data.
   XXX: A bootinfo_magic record is not checked for at the moment, even
        though test bootblocks initialise the bootinfo data with one.

 o Use the bootinfo symtab information in preference to searching for a
   valid a.out exec header after _end for initialising DDB.
   XXX: Should retire a.out exec header support altogether.  Loosing the
        ability to load symbols from old bootblocks isn't much of a loss.
        After 1.4?

 o Add "booted kernel" machdep sysctl.

3993ee01e4 Don't enable I/O or memory access here! These bits in the PCI CSR are 
set up by the firmware, and indicate which mapping types the system
supports.

aca34380db If on entry the stack is within 4kB of _start, don't reset the stack 
pointer to just underneath _start.  Allows bootblocks (or other kernel
calling programs) to pass more than 4 arguments if it sets up the stack
properly.

The 4kB figure may be overkill - on the pmax it only needs to be a dozen
of so bytes.

1c99e4196a Use BUS_SPACE_ALIGNED_POINTER() instead of ALIGNED_POINTER() where the pointer 
in not just used to access memory but is bassed to bus_space_xxx_n()
methods. For debugging purposes, bus_space can have additional constraints
which will be properly met by BUS_SPACE_ALIGNED_POINTER().

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.
