f455dd6596 add a `flags' argument to uvm_pagealloc_strat(). 
define a flag UVM_PGA_USERESERVE to allow non-kernel object
allocations to use pages from the reserve.
use the new flag for allocations in pmap modules.

9c6b797796 Changes for modified pmap_enter() API: 
* Map the message buffer with access_type = VM_PROT_READ|VM_PROT_WRITE `just
  because'.
* Map the file system buffers with access_type = VM_PROT_READ|VM_PROT_WRITE to
  avoid possible problems with pagemove().
* Do not use VM_PROT_EXEC with either of the above.
* Map pages for /dev/mem with access_type = prot.  Also, DO NOT use
  pmap_kenter() for this, as we DO NOT want to lose modification information.
* Map pages in dumpsys() with VM_PROT_READ.
* Map pages in m68k mappedcopyin()/mappedcopyout() and writeback() with
  access_type = prot.
* For now, bus_dma*(), pmap_map(), vmapbuf(), and similar functions still use
  access_type = 0.  This should probably be revisited.

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)

bb8971afc3 for emul_sunos processes, don't change vmspace->vm_maxsaddr 
for faults within a fudge factor of the end of the stack.
the sunos ld.so maps some zero-fill memory there and uses
it while loading shared libs.  ignoring these shenanigans
allows ps to report the correct stack usage for sunos programs.

69d2d27c1b Use bus_space tags and handles, embedded in MD hooks AM7930_{READ_WRITE}_REG 
to handle MD delay and bus padding. Tested on sparc2 by David Brownlee.

Should use regmaps, but that breaks sparc pDMA assembly code.

49035b27c8 Do not call printf() from a CPU that is spinning up; defer the probe 
messages to cpu_attach() where the boot processor takes care of them.
This also necessitates a slight change in the way the FPU name is stored.

372e76a3bb Since V2 & V3 proms already pass us ihandles for stdin and stdout, 
there's no need to open the device a second time. It suffices to
just convert the `ihandles' to `phandles'.
