2014-05-30	KVM: PPC: Disable NX for old magic page using guests	Alexander Graf	1	-0/+14
	Old guests try to use the magic page, but map their trampoline code inside of an NX region. Since we can't fix those old kernels, try to detect whether the guest is sane or not. If not, just disable NX functionality in KVM so that old guests at least work at all. For newer guests, add a bit that we can set to keep NX functionality available.

2012-05-30	KVM: PPC: Not optimizing MSR_CE and MSR_ME with paravirt.	Bharat Bhushan	1	-2/+0
	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.

2012-03-05	KVM: PPC: refer to paravirt docs in header file	Scott Wood	1	-22/+2
	Instead of keeping separate copies of struct kvm_vcpu_arch_shared (one in the code, one in the docs) that inevitably fail to be kept in sync (already sr[] is missing from the doc version), just point to the header file as the source of documentation on the contents of the magic page.

2011-07-12	KVM: PPC: e500: enable magic page	Scott Wood	1	-3/+5
	This is a shared page used for paravirtualization. It is always present in the guest kernel's effective address space at the address indicated by the hypercall that enables it. The physical address specified by the hypercall is not used, as e500 does not have real mode. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Alexander Graf <agraf@suse.de>
