From: Andrey Smetanin Date: Mon, 30 Nov 2015 16:22:15 +0000 (+0300) Subject: drivers/hv: Move struct hv_message into UAPI Hyper-V x86 header X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=5b423efe11e822e092e8c911a6bad17eadf718eb;p=openwrt%2Fstaging%2Fblogic.git drivers/hv: Move struct hv_message into UAPI Hyper-V x86 header This struct is required for Hyper-V SynIC timers implementation inside KVM and for upcoming Hyper-V VMBus support by userspace(QEMU). So place it into Hyper-V UAPI header. Signed-off-by: Andrey Smetanin Acked-by: K. Y. Srinivasan Reviewed-by: Roman Kagan CC: Gleb Natapov CC: Paolo Bonzini CC: "K. Y.
