Done, but this queue has not been in linux-next. Please push to
kvm-ppc-next on your github Linux tree as well; please keep an eye on

This fixes a bug in the tracking of pages that get modified by the
guest. If the guest creates a large-page HPTE, writes to memory
somewhere within the large page, and then removes the HPTE, we only
record the modified state for the first normal page within the large
page, w

When compiling the KVM code for POWER with "make C=1", sparse
complains about functions missing proper prototypes and a 64-bit
constant missing the ULL prefix. Let's fix this by making the
functions static or by including the proper header with the
prototypes, and by appending a

Since the PPC970 support has been removed from the kvm-hv kernel
module recently, we should also reflect this change in the help

When running a virtual core of a guest that is configured with fewer
threads per core than the physical cores have, the extra physical
threads are currently unused. This makes it possible to use them to
run one or more other virtual cores from the same guest when certain

In 64 bit kernels, the Fixed Point Exception Register (XER) is a 64
bit field (e.g. in kvm_regs and kvm_vcpu_arch) and in most places it is
accessed as such.
This patch corrects places where it is accessed as a 32 bit field by a
64 bit kernel. In some cases this is via a 32 bi

This adds implementations for the H_CLEAR_REF (test and clear reference
bit) and H_CLEAR_MOD (test and clear changed bit) hypercalls.
When clearing the reference or change bit in the guest view of the HPTE,
we also have to clear it in the real HPTE so that we can detect futu

When a vcore gets preempted, we put it on the preempted vcore list for
the current CPU. The runner task then calls schedule() and comes back
some time later and takes itself off the list. We need to be careful
to lock the list that it was put onto, which may not be the list
From: Paul Mackerras
Whenever a vcore state is VCORE_PREEMPT we need to be counting stolen
time for it. This currently isn't the case when we have a vcore that
no longer has any runnable threads in it but still has a runner task,
so we do an explicit call to kvmppc_core_start_stolen() in that ca

This builds on the ability to run more than one vcore on a physical
core by using the micro-threading (split-core) modes of the POWER8
chip. Previously, only vcores from the same VM could be run together,
and (on POWER8) only if they had just one thread per core. With the

The reference (R) and change (C) bits in a HPT entry can be set by
hardware at any time up until the HPTE is invalidated and the TLB
invalidation sequence has completed. This means that when removing
a HPTE, we need to read the HPTE after the invalidation sequence has
