Subject: [Qemu-devel] 4GB/4GB split

Hi,
I just saw the announce of Ingo Molnar about his patch for 4GB/4GB
kernel split. This patch is mostly what I was dreaming in order to have
optimal performances in QEMU : no guest kernel patches will be necessary
and no software MMU will be necessary.
I hope that some of the kernel gurus reading this list will tell Ingo
that his patch may be useful also for people having less than 4GB of RAM :-)
Ideally, he should add a feature to activate the 4GB/4GB on demand (if
the user process maps data above 0xc0000000) and he should also be able
to move dynamically the trampoline page if the user process tries to map
something at its address.
Fabrice.
