2204402aa1 If KERN_LDSCRIPT is specified as a makeoption, then add it to the 
linker flags.

1946ce2a42 A linker script based on elf_i386.x which aligns the .data segment 
to a 4MB boundary, thus allowing the text and read-only data to be
mapped using large pages.

fbc40806dd vtopte() and kvtopte() now check for kernel vs. non-kernel addresses,

5f98fd6c03 On second thought, back out kvtopte() change in previous. Dug, PT pages 
are in a special VA range, not kernel VA range.

7f3786d36a Add preliminary support for the MVME162-LX 200/300 series of boards. 
Currently, the major onboard devices are supported (disk, network,
rs232 and VMEbus). However, work is still need to support the remaining
devices (eg. IndustryPack sites).

These boards are available with a dazzling array of build options. At
this time, the following options are *required*:

	o Real floating point hardware (the 68LC040 model isn't tested),
	o The VMEchip2 must be present,
	o If offboard VMEbus RAM is not present, at least 8MB of onboard
	  RAM is required.
	o Even if offboard VMEbus RAM *is* present, at least 4MB of onboard
	  RAM is required. (Boards with 1 or 2MB onboard RAM *can* be
	  supported with offboard RAM, but not without some funky values in
	  the VMEbus Master mapping registers.)

There is no support for boards other than those in the -LX 200/300 series.

b38096892a Microtime calculation was seriously incorrect when HZ != 100 
Give rest of clock interrupt code a revamp.  Because we are using an external
cycle counter we can now handle loosing several hundred interrupts without
the time slipping.

8f2cc012b5 Remove 3 of the nops between tlbwr and eret in tlb miss handlers. They 
were added early when adding the QED support.  RM5231 seems to work fine
w/o the extra nops.  Noticed by Chuck Cranor.

eac566737e In pmap_extract(): 
- Return FALSE if the PTE does not have PG_V set (previously, you would
  get always get true of the PDE was valid, even if the PTE was not).
- Teach it about 4MB pages.
