Alexander Graf f3383cf80e KVM: PPC: Disable NX for old magic page using guests
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.

Bharat Bhushan d35b1075af KVM: PPC: Not optimizing MSR_CE and MSR_ME with paravirt.
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.

Scott Wood 54f65795c8 KVM: PPC: refer to paravirt docs in header file
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.

Scott Wood a4cd8b23ac KVM: PPC: e500: enable magic page
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.
