From 2743103f91e20d4c4d4f1a8d00821289c4c6ff62 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Thu, 24 Apr 2014 13:39:16 +0200 Subject: [PATCH] KVM: PPC: PR: Fill pvinfo hcall instructions in big endian We expose a blob of hypercall instructions to user space that it gives to the guest via device tree again. That blob should contain a stream of instructions necessary to do a hypercall in big endian, as it just gets passed into the guest and old guests use them straight away.
