*	KVM: ppc: fix invalidation of large guest pages	Hollis Blanchard	2008-07-27	2	-3/+4
\| \| \| \| \| \| \| \| \| \|	When guest invalidates a large tlb map, there may be more than one corresponding shadow tlb maps that need to be invalidated. Use eaddr and eend to find these shadow tlb maps. Signed-off-by: Liu Yu <yu.liu@freescale.com> Signed-off-by: Hollis Blanchard <hollisb@us.ibm.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
*	KVM: MMU: nuke shadowed pgtable pages and ptes on memslot destruction	Marcelo Tosatti	2008-07-20	1	-0/+4
\| \| \| \| \| \| \|	Flush the shadow mmu before removing regions to avoid stale entries. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
*	KVM: Add coalesced MMIO support (powerpc part)	Laurent Vivier	2008-07-20	2	-1/+4
\| \| \| \| \| \| \| \| \|	This patch enables coalesced MMIO for powerpc architecture. It defines KVM_MMIO_PAGE_OFFSET and KVM_CAP_COALESCED_MMIO. It enables the compilation of coalesced_mmio.c. Signed-off-by: Laurent Vivier <Laurent.Vivier@bull.net> Signed-off-by: Avi Kivity <avi@qumranet.com>
*	KVM: Remove decache_vcpus_on_cpu() and related callbacks	Avi Kivity	2008-07-20	1	-4/+0
\| \| \| \| \| \|	Obsoleted by the vmx-specific per-cpu list. Signed-off-by: Avi Kivity <avi@qumranet.com>
*	KVM: ppc: Report bad GFNs	Hollis Blanchard	2008-06-06	1	-1/+1
\| \| \| \| \| \| \| \|	This code shouldn't be hit anyways, but when it is, it's useful to have a little more information about the failure. Signed-off-by: Hollis Blanchard <hollisb@us.ibm.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
*	KVM: ppc: Use a read lock around MMU operations, and release it on error	Hollis Blanchard	2008-06-06	1	-2/+3
\| \| \| \| \| \| \| \|	gfn_to_page() and kvm_release_page_clean() are called from other contexts with mmap_sem locked only for reading. Signed-off-by: Hollis Blanchard <hollisb@us.ibm.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
*	KVM: ppc: Remove unmatched kunmap() call	Hollis Blanchard	2008-06-06	1	-2/+0
\| \| \| \| \| \| \| \| \| \| \|	We're not calling kmap() now, so we shouldn't call kunmap() either. This has no practical effect in the non-highmem case, which is why it hasn't caused more obvious problems. Pointed out by Anthony Liguori.

*	KVM: ppc: add lwzx/stwz emulation	Hollis Blanchard	2008-06-06	1	-0/+12
\| \| \| \| \| \| \| \| \|	Somehow these load/store instructions got missed before, but weren't used by the guest so didn't break anything.

*	KVM: ppc: Remove duplicate function	Hollis Blanchard	2008-06-06	1	-33/+0
\| \| \| \| \| \| \|	This was left behind from some code movement. Signed-off-by: Hollis Blanchard <hollisb@us.ibm.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
*	KVM: ppc: deliver INTERRUPT_FP_UNAVAIL to the guest	Christian Ehrhardt	2008-05-04	1	-0/+5
\| \| \| \| \| \| \| \| \|	This patch adds the delivery of INTERRUPT_FP_UNAVAIL exceptions to the guest. It's needed if a guest uses ppc binaries using the Floating point instructions.

*	KVM: ppc: Handle guest idle by emulating MSR[WE] writes	Hollis Blanchard	2008-05-04	2	-3/+18
\| \| \| \| \| \| \| \| \|	This reduces host CPU usage when the guest is idle. However, the guest must set MSR[WE] in its idle loop, which Linux did not do until 2.6.26.

*	KVM: ppc: PowerPC 440 KVM implementation	Hollis Blanchard	2008-04-27	9	-0/+2702
	This functionality is definitely experimental, but is capable of running unmodified PowerPC 440 Linux kernels as guests on a PowerPC 440 host. (Only tested with 440EP "Bamboo" guests so far, but with appropriate userspace support other SoC/board combinations should work.) See Documentation/powerpc/kvm_440.txt for technical details.
