Hi,

Just browsing over the pmap code, and noticed this comment:
 *     o If the vector_page is at 0x00000000 instead of 0xffff0000, then
 *       MP systems will lose big-time because of the MMU domain hack.
 *       The only way this can be solved (apart from moving the vector
 *       page to 0xffff0000) is to reserve the first 1MB of user address
 *       space for kernel use only. This would require re-linking all
 *       applications so that the text section starts above this 1MB
 *       boundary.

I know that currently we don't do MP on arm, there was some work done to
support hydra MP, and long term I believe that arch v6 chips will
support SMP (although I'd guess they can remap the vector table)

However I was wondering if NetBSD 2.0 would be a good day time to do
this?
