Re: [PATCH 1/1] Implement shared page tables

Which is indeed a further disincentive against shared page tables.

Or shared pagetables a disincentive to randomizing the mmap space ;-)
They're incompatible, but you could be left to choose one or the other
via config option.

3% on "a certain industry-standard database benchmark" (cough) is huge,
and we expect the benefit for PPC64 will be larger as we can share the
underlying hardware PTEs without TLB flushing as well.

surely the benchmark people know that the database in question always
mmaps the shared area at the address where the first one started it?
(if not, could make it so ;)
