Subject: [PATCH v5.1 4/6] KVM: PPC: Book3S: modify kvmppc_need_byteswap() for little endian host
Date: Fri, 08 Nov 2013 14:36:09 +0000 [thread overview]
Message-ID: <527CF6D9.3050300@fr.ibm.com> (raw)
In-Reply-To: <1383672128-26795-5-git-send-email-clg@fr.ibm.com>
If the host has the same endian order as the guest, there is no need
to byte-swap.
