a662b8135a KVM: ia64: fix build breakage due to host spinlock change
Len Brown pointed out that allmodconfig is broken for
ia64 because of:

arch/ia64/kvm/vmm.c: In function 'vmm_spin_unlock':
arch/ia64/kvm/vmm.c:70: error: 'spinlock_t' has no member named 'raw_lock'

KVM has it's own spinlock routines. It should not depend on the base kernel
spinlock_t type (which changed when ia64 switched to ticket locks).  Define
its own vmm_spinlock_t type.

9f7d5bb5e2 KVM: ia64: Add handler for crashed vmm
Since vmm runs in an isolated address space and it is just a copy
of host's kvm-intel module, so once vmm crashes, we just crash all guests
running on it instead of crashing whole kernel.

c60ff51eb2 KVM: ia64: fix vmm_spin_{un}lock for !CONFIG_SMP
In the case of !CONFIG_SMP, raw_spinlock_t is empty and the spinlock functions
don't build.  Fix by defining spinlock functions for the uniprocessor case.
