Kernel version is 2.6.30 and I have enabled fsl DMA engine during
configuring kernel. After system booted, I have seen only 38 DMA
interrupts, and no increase later when I am doing data transfer
through network.
So I wonder if mpc8548 had made use of DMA engine when doing memcpy,

Yes, my branch is based on linus-git as of today. The CAN driver addition was
just posted to socketcan-devel. It is also independent of the denx-patches[1]
and will later be send to netdev, too.

This is the really low level of guest entry/exit code.
Book3s_64 has an SLB, which stores all ESID -> VSID mappings we're
currently aware of.
The segments in the guest differ from the ones on the host, so we need
to switch the SLB to tell the MMU that we're in a new context.
So we store a shadow
For KVM we need to allocate a new context id, but don't really care about
all the mm context around it.
So let's split the alloc and destroy functions for the context id, so we can
grab one without allocating an mm context.

Following S390's good example we should use hrtimers for the decrementer too!
This patch converts the timer from the old mechanism to hrtimers.

I have tested this patch on my MPC8548 machine box, kernel version is
2.6.30. There is a problem.
