eb20bbc780 Change the semantics of splsoftclock() to be like other spl*() functions, 
that is priority is rasied.  Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.

This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).

XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX.  This platforms still have this bug until their
XXX spl*() functions are fixed.

ecdad0ec33 clean up a bit after jason :) 
- fix emitrules() like emitfiles() to deal with the prefix (otherwise it
  would attempt to find the file in the normal base for the NORMAL_C rule).
- add emitincludes() which adds include directives for each prefix to the
  $INCLUDES variable in the makefile.
- add %INCLUDES to each Makefile.arch to deal with the above.

this makes "prefix" actually work in a usable manner, and now i can move
on to fixing compiler warnings (errors) in the ESP code. :)

2580d306ab Change the vm_map's "entries_pageable" member to a r/o flags member, which 
has PAGEABLE and INTRSAFE flags.  PAGEABLE now really means "pageable",
not "allocate vm_map_entry's from non-static pool", so update all map
creations to reflect that.  INTRSAFE maps are maps that are used in
interrupt context (e.g. kmem_map, mb_map), and thus use the static
map entry pool (XXX as does kernel_map, for now).  This will eventually
change now these maps are locked, as well.

5832084eaf bus_dmamem_map() maps DMA safe memory, which is usually one or more 
managed pages, into KVA space.  Since the pages are managed, we should
use pmap_enter(), not pmap_kenter_pa().

Also, when entering the mappings, enter with an access_type of
VM_PROT_READ | VM_PROT_WRITE.  We do this for a couple of reasons:

	(1) On systems that have H/W mod/ref attributes, the hardware
	    may not be able to track mod/ref done by a bus master.

	(2) On systems that have to do mod/ref emulation, this prevents
	    a mod/ref page fault from potentially happening while in an
	    interrupt context, which can be problematic.

This latter change is fairly important if we ever want to be able to
transfer DMA-safe memory pages to anonymous memory objects; we will need
to know that the pages are modified, or else data could be lost!

Note that while the pages are unowned (i.e. "just DMA-safe memory pages"),
they won't consume any swap resources, as the mappings are wired, and
the pages aren't on the active or inactive queues.

f98d358a1f Rework layer 2 protocol input routines. Instead of calling e.g. ether_input() 
directly, call the function pointer (*if_input)(ifp, m).  The input routine
expects the packet header to be at the head of the packet, and will adjust
as necessary.  Privatize the layer 2 input and output routines, allowing
*_ifattach() to set them up as appropriate.

c10a926030 Allow the caller to specify a stack for the child process. If NULL, 
the child inherits the stack pointer from the parent (traditional
behavior).  Like the signal stack, the stack area is secified as
a low address and a size; machine-dependent code accounts for stack
direction.

This is required for clone(2).

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.

merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid

38084c6615 Note that trap #1 is compat_13_sigreturn, and give trap #3 to syscalls 
which require special handling, e.g. sigreturn on m68k.

This differs from the old sigreturn trap in that we require the syscall
number to be in register d0, just like the regular syscall entry point.
This will allow sigreturn to be versioned in the future without the need
to allocate another trap vector.
