62db8972b1 Updated bde's comments wrt. i387 control word settings so that they 
describe NetBSD, rather than 386BSD 0.1.
Removed 386BSD and BDE control word constants, since we don't need and
will never use them.  However, The iBCS control word constant is kept,
since we might want to use it in the iBCS binary compatibility code.

4116a4243e 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.

b3b55d02f1 Misc changes to make this file more like the asm.h headers used by other 
architectures:
	Renamed _C_FUNC() to _C_LABEL()
	Renamed _ASM_FUNC() to _ASM_LABEL()
	Merged _BEGIN_ENTRY with _ENTRY
	Renamed _END_ENTRY to _PROF_PROLOGUE

When assembling with profiling enabled, set up stack frame before calling
mcount() in _PROF_PROLOGUE.  Also omit emitting .long 0's, as they are no
longer used by the profiling code.

faster (on the i486 & i586) rorw $8, %w1.  The inline assembly for GCC 1.X
already used rorw.  Using rorw is one byte longer, but we wouldn't be
inlining at all if we weren't optimizing for speed.

2a51c00a70 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.

dced52af6c bump MAXSSIZ back down to 8M (from 256M, where charles put it). 
execve() currently allocated MAXSSIZ of address space (AND PAGE TABLES)

updated to match, MAXSSIZ==256M will make execve() significantly slower
than MAXSSIZ==8M.
