cgd b8403d582b don't be so quick to cast macro arguments to unsigned; if the
arguments are really off_t's (e.g. to btodb), then you can lose
information.  This was the "> 4G file systems don't work" bug; physio
uses btodb, which was broken.

jtc 830a53e394 ANSI says that <stdarg.h>'s va_end macro must expand to a void expression.
For consistancy, I'm changing <varargs.h> too.

jtc 9540190d45 This file, which will be included by <sys/cdefs.h>, will contain macros
such as __warn_references() and __weak_reference() which are actually
machine dependant.  This will make it easier for ports that are being
bootstraped with ELF and ECOFF based toolchains.

This change also introduces a new macro, _C_LABEL(x).  _C_LABEL expands
its argument, an identifier, to a character string of the identifier
name as it is represented in an object file.

For most ports, _C_LABEL(x) will expand to "_x", for ELF based ports
_C_LABEL(x) will expand to "x".

mycroft ecef8fddfa Remove PSL_USERCLR, and add a PSL_USERSTATIC. Change the bit descriptions to
more closely match the 386 manual.  (Probably the mnemonics should be changed,
too.)

mycroft 205d425f2f As pointed out by Bruce, splsoftclock() needs to process pending interrupts
when lowering the priority.  Do this by simply calling splx().  For the
benefit of NFS (for now), modify splx() to return a value so that
splsoftclock() does.  This work is optimized out for every use of splx()
that ignores the value, so it only affects relevant code.
Also, clean up this file a little.

mycroft 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.

jtc 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.

jtc 2a51c00a70 FPU control word of 0x137f doesn't work well in "real" world applications

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.
