Various changes:
...
* Inline some functions.
* Eliminate redundant calls to pmap_page_index().
* Reduce the number of TLB flushes in accordance with the i386 SSWG.
* Inline pmap_remove() in pmap_remove_all(). (Most if it is unnecessary.)
* Allocate pv_entry's in pages, and keep a list of free entries in each page,
and a list of pages with free entries. (Trying to reduce malloc() overhead,
and improve locality of reference.)
* Remove a couple of macros that aren't really useful.
* Remove pmap_kernel() completely.

faster (on the i486 & i586) rorw $8, %w1. The inline assembly for GCC 1.X

FPU control word of 0x137f doesn't work well in "real" world applications
...
so I've changed it to 0x127f. 64 bit precision causes errors in paranoia
and our math library, changing to 53 bit precision solves these problems.
I've been told that long double support in Gcc 2.5 requires 64 bit mode,
so a comprehensive FP strategy (compiler, library, FPU, emulator) will
have to be addressed in the future.

execve() currently allocated MAXSSIZ of address space (AND PAGE TABLES)
