I've used a kernel with these old pmap.h and pmap.c for a
while.  I've experienced one kernel panic while I was
compiling entire user land.  I've experienced other two
lock-ups.  Jukka said he got two panics on the repe stols or
something like that instruction.  It is not so stable what I

I can say it is more useful because the number of panics is
smaller than current one.  However, I should not say it is
stable.  Sorry about my last email.

On the other hand, my last stable kernel was 3/25 09:27.  At
that time, pmap.h was 1.43, and pmap.c was 1.84.  I guess
some later changes on pmap.c is required to make recent
kernel stable.  Therefore, I increased the version of both
to see what I can do.

I decided to use 1.44 pmap.h with changes to uncomment the
definition of PMAP_PAGEIDLEZERO macro and 1.90 pmap.c
without changes.  Because, 1.90's comments looks like
important bug fix.  It says "NULL != 0."  :-)

By using this versioned kernel, I could compile entire user
land without any panics.  I think this is OK to call stable
now.  Otherguys who have Cyrix, could you test this
configuration?  For the people who don't use anoncvs, I put
both pmap.h and pmap.c at
