kmem_flags 7f on Sun Ray server

The quest to run the latest development build of Solaris on our Sun Ray server continues, this time with a twist. Just to try and flush some more bugs out of the system we have set kmem_flags to 7f. If you look in /usr/include/sys/kmem_impl.h you will see what this gets us (it has not changed since Solaris 10). We now have each allocation fitting in it's own page and the Sun Ray server is running but is slower than is really acceptable. Looks like we have shown that there are no obvious kmem cock ups. I think we will DR in a new board, which we have to get the fastest parts in the lab warm, and if it survives that unset the kmem_flags (I wonder if we can do that dynamically), if not then we can see if it survives until the end of the day. We can't really leave it like this as as Tim just said: “It is a bit sedate”.

Anyway top marks to the lab staff for giving this a go.
