830666e31e Clean the icache for pages when they are entered as executable and before 
they were either not mapped at all or mapped as non-executable.  Round
memory regions in pmap_bootstrap.

12810ed37d Use size_t in prototype (so this will be LP64 clean for PPC64 someday). 
Calculate len separately for icache & dcache in case each has different
cacheline widths.  Make the code for both loops the same except for the
dcbst/icbi.  Deal with sizes >=2GB properly (like that'll happen but ...)

7e9d845469 * Add MPC601 versions of BAT_VA_MATCH_P() and BAT_VALID_P(). 
* Make the extern declaration of the battable array incomplete;
  a given port might want to use a differently-sized definition to
  support the 601 BAT implementation, where blocks map up to 8M only.

2d8577fb83 Clean up some rampant code duplication wrt ieee number handling: 
- Add alignment-safe double and float unions.
 - Use the above for the __infinity and __nan constants on all
   architectures that use the standard ieee754 representation of
   those constants.
 - Add a single copy of various ieee754 math functions (frexp, isinf,
   isnan, ldexp and modf) that had numerous duplicates among the
   arch-specific directories.
 - Use the above functions on all architectures where the generic C
   versions where used.  Architectures that had local assembly
   routines are untouched (for those functions only).

0e7661f023 Update pmap_update to now take the updated pmap as an argument. 
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.
