From 54f65795c8f6e192540756085d738e66ab0917a0 Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Wed, 11 Jan 2012 13:37:35 +0000 Subject: 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.
