It's not surprising. 650 lines including a custom memory allocator is
excessive.

We use kfree in svm.c and vmx.c, and this works, but it could break at

Hi Team,
I don't know if anyone here also subscribes to linux-rt-users, but it
seems as though Ingo et. al. rejected my modifications which ran the
smp_call() in a thread (VFCIPI). So FYI: KVM is still broken on RT and
needs to be addressed.

I rebased the lapic2 branch onto current master. Because there were
many nontrivial changes, the result is in a new branch, lapic3. This is
for both kernel and userspace.

Well since KVM uses QEMU you'd really be writing a frontend for that.

More fallout from the writeback fixes: debug register transfer instructions
do their own writeback and thus need to disable the general writeback
mechanism. This fixes oopses and some guest failures on AMD machines (the
