ugh, silly me. I saw you were doing something but never looked into it, i
thought it was the memory.c inline hack that went into 2.1 recently ;)
Maybe could you guys working on the vger tree announce bigger hacks on
linux-kernel, so people who dont have fast enough CVS access dont waste
time ;)
a related issue, i first tried to implement shared page tables, and in the
process of cleaning it up i noticed that it makes almost no sense (we have
only a few page tables usually, and they almost always have dirty pages).
Then i noticed how compact our page tables actually are and implemented
the above hack ... ;)
