Initial commit of the port to AMD's upcoming 64 bit architecture, the 

x86-64. Since there's no hardware available yet, this port is only
known to run on the Simics simulator for at the moment, and as such
uses the PC devices that it simulates for now. It will be developed
more (and cleaned up) as the hardware becomes available.

* ANSI C), but they use _RUNE_T_ instead of int. By changing it here, you
* lose a bit of ANSI conformance, but your programs will still work.
*
* Note that _WCHAR_T_ and _RUNE_T_ must be of the same type. When wchar_t

* The x86_64 pmap module closely resembles the i386 one. It uses
* the same recursive entry scheme, and the same alternate area
* trick for accessing non-current pmaps. See the i386 pmap.h
* for a description. The obvious difference is that 3 extra
* levels of page table need to be dealt with. The level 1 page
* table pages are at:
*
* l1: 0x00007f8000000000 - 0x00007fffffffffff (39 bits, needs PML4 entry)
*
* The alternate space is at:
*
* l1: 0xffffff8000000000 - 0xffffffffffffffff (39 bits, needs PML4 entry)
*
* The rest is kept as physical pages in 3 UVM objects, and is
* temporarily mapped for virtual access when needed.
*
* Note that address space is signed, so the layout for 48 bits is:
*
* +---------------------------------+ 0xffffffffffffffff
* | |
* | alt.L1 table (PTE pages) |
* | |
* +---------------------------------+ 0xffffff8000000000
* ~ ~
* | |
* | Kernel Space |
* | |
* | |
* +---------------------------------+ 0xffff800000000000 = 0x0000008000000000
* | |
* | alt.L1 table (PTE pages) |
* | |
* +---------------------------------+ 0x00007f8000000000
* ~ ~
* | |
* | User Space |
* | |
* | |
* +---------------------------------+ 0x0000000000000000
*
* In other words, there is a 'VA hole' at 0x0000008000000000 -
* 0xffff800000000000 which will trap, just as on, for example,
* sparcv9.
*

* complexity to the calculations.

* Macros for interrupt entry, call to handler, and exit.
*
* XXX
* The interrupt frame is set up to look like a trap frame. This may be a
* waste. The only handler which needs a frame is the clock handler, and it
* only needs a few bits. Xdoreti() needs a trap frame for handling ASTs, but
* it could easily convert the frame on demand.
*
* The direct costs of setting up a trap frame are two pushl's (error code and
* trap number), an addl to get rid of these, and pushing and popping the
* callee-saved registers %esi, %edi, %ebx, and %ebp twice.
*
* If the interrupt frame is made more flexible, INTR can push %eax first and
* decide the ipending case with less overhead, e.g., by avoiding loading the
* segment registers.
*
* XXX
* Should we do a cld on every system entry to avoid the requirement for
* scattered cld's?

* We cdr down the intrhand chain, calling each handler with its appropriate
* argument (0 meaning a pointer to the frame, for clock interrupts).
*
* The handler returns one of three values:
* 0 - This interrupt wasn't for me.
* 1 - This interrupt was for me.
* -1 - This interrupt might have been for me, but I don't know.
* If there are no handlers, or they all return 0, we flags it as a `stray'
* interrupt. On a system with level-triggered interrupts, we could terminate
* immediately when one of them returns 1; but this is a PC.
*
* On exit, we jump to Xdoreti(), to process soft interrupts and ASTs.
