This patch against qemu upstream adds notifiers hook which lets backends
get notified on memory changes, and converts kvm to use it. It survived
light testing. Avi, could you please take a look at this patch?
Thanks!

This adds notifiers for phys memory changes: a set of callbacks that
vhost can register and update kernel accordingly. Down the road, kvm
code can be switched to use these as well, instead of calling kvm code
directly from exec.c as is done now.

remove direct kvm calls from exec.c, make
kvm use memory notifiers framework instead.

Mainly because I'm not sure that you can have sane universal semantics

Move userland PALcode handling into linux-user main loop so that
we can send signals from there. This also makes alpha_palcode.c
system-level only, so don't build it for userland. Add defines
for GENTRAP PALcall mapping to signals.

The existing set of IPRs is totally irrelevant to user-mode emulation.
Indeed, they most are irrelevant to implementing kernel-mode emulation,
and would only be relevant to PAL-mode emulation, which I suspect that
no one will ever attempt.
