gwr 7190ad9936 Fix a major bug in pmap_remove_kernel() that causd the removal of 
one page too many (worse, it unmapped our stack page... Ouch!)
Also, use loadcrp() and such instead of calling pmap_activate
in various places so we have more control over TLB flush.
Now pmap_activate() is called only by locore (and that call is
done only if PMAP_DEBUG is defined).  Other minor clean-up...

jonathan 4fdff0ed65 * Add ep_complete_cmd() function, to issue commands that perform a reset 
(RX_RESET, TX_RESET, GLOBAL_RESET).
  Commands issued while a reset is in progress may be dropped. The driver
  must wait until resets are complete; ep_complete_cmd() does so.
* Change RX_RESET,  TX_RESET, GLOBAL_RESET to use ep_complete_cmd().

* Revert epconfig() to use inline RX_RESET, TX_RESET.
  That avoids accidentally setting IFF_UP, which  breaks both diskless boot,
  and "halt" commands issued before the interface is brought up.

perry 0c7dacfcec All these files are ancient and haven't been used in years -- the 
current boot blocks are in boot/; we need the thing cleaned out so we
can put the new libsa based boot stuff in its place.

appropriately.

Also, attach fpu to mainbus, rather than obio.

* Add table-driven assembly-coded microtime().

   * add boot-time computation of the interpolation table,

     nonstandard values of HZ or TIMER_FREQ.

   * delete old C version of microtime().
