included twice as a side effect of including unrelated headers, but I
removed the #include of one of the headers and will soon fix the nested
#include in the other.
the file so that this compiles without forward declarations of that
data. (It is impossible to forward-declare static data in Gnu C.
Declaring it as static is correct, but causes bogus warnings from
gcc -Wredundant-decls. Declaring it as extern works, but causes
correct warnings from gcc -pedantic and is undefined in ANSI C.
We usually declare it as extern. Here it was once really extern,
but botched staticization left it as static here and apparently-
extern in a header file.)

Moved description of sio 16650A flag to the sio section and rewrote the
description. It was in the generic console flags section.
Added undocumented options CPU_UPGRADE_HW_CACHE and WLDEBUG.
This define enables the code to ALWAYS run the 8254 timer thru the 8259 ICU.
It is ON by default.
It depricates the usage of "options SMP_TIMER_NC" in the config file.
1/ is compatible with the old route(1) in case needed.
2/ actually fixes the problem while vetting bad user input.
note: I have already fixed route(1) so the problem shouldn't occur.
if it does. use 0.0.0.0/0 instead of the word 'default' :)
1) Make sure that the region mapped by a 4MB page is
properly aligned.
2) Don't turn on the PG_G flag in locore for SMP. I plan
to do that later in startup anyway.
3) Make sure the 2nd processor has PSE enabled, so that 4MB
pages don't hose it.
We don't use PG_G yet on SMP -- there is work to be done to make that
work correctly. It isn't that important anyway...
We need to accept at least one sockaddr with zero length, in order
to be able to set the default route.
Suggested by: Phone conversation with Julian (sleep well!)
of the kernel, and also most of the dynamic parts of the kernel. Additionally,
4MB pages will be allocated for display buffers as appropriate (only.)
The 4MB support for SMP isn't complete, but doesn't interfere with operation
either.
