This adds a kvm-specific hypervisor call to the pseries machine
which allows to do what amounts to memmove, memcpy and xor over
regions of physical memory such as the framebuffer.
This is the simplest way to get usable framebuffer speed from
SLOF since the framebuffer isn't mapped in the VRMA and

Added the decrementer auto-reload support. DECAR is readable
on e500v2/e500mc and later cpus.

If there is pending critical or machine check interrupt then guest
would like to capture it when guest enable MSR.CE and MSR_ME respectively.
Also as mostly MSR_CE and MSR_ME are updated with rfi/rfci/rfmii
which anyway traps so removing the the paravirt optimization for MSR.CE
and MSR.ME.

Hi
I'm working on KVM optimizations on Powerpc e500v2 embedded architecture. For
my
project i'm trying to increase the size of shared region mapped my Magic Page
between host and guest for paravirtual support. I was expecting this would
possible since we are using a TLB1 entry to map the magic
