:> Hi,
:> Forgive the naive question, but is this an easy issue to solve ?
:> Or is it just scratching the surface of a larger more complex problem not
:> easily resolved by a simple patch or two ?
:
:I'm enclosed a patch that introduces PADDR2/PMAP2 which is to be used
:by pmap_pte() (should not be called from interrupts on noncurrent
:pmaps) while pmap_pte_quick() (should not be called without splvm()
:protection) will use PADDR1/PMAP1.
:
:The patch also backs out revision 1.250.2.20 of
:src/sys/i386/i386/pmap.c.

Tor, this looks like it could have been an issue even before the PAE
patch went in. What are your thoughts on the matter?
