We accidently broke SMP when we moved mptable init to before we initialize the
vcpu
count, that means that we always built smptable which was not properly

for the given configuration.
Instead of initializing mptable as part of the kvm arch initialization, let it
be initialized on
I've accidently changed optimization level to -O0 when testing one of the

Support using build-time check tools when building lkvm. This allows
using tools such as smatch with the same syntax used with kernel

For example, to build with smatch checks, first make sure you have

Updated with suggestions from Michael and Avi, the OADN option is
now a resample option. Re-working locking went surprisingly
well, lockdep clean, and now allows us to use a single irq source
ID for all resample irqfds. I hope we're close. Thanks,
