Peter Anvin <hpa@xxxxxxxxxxxxxxx> CommitDate: Mon, 11 Feb 2013 17:18:12 -0800 x86, uv, uv3: Update Time Support for SGI UV3 This patch updates time support for the SGI UV3 hub. Since the UV2 and UV3 time support is identical, "is_uvx_hub" is used instead of having both "is_uv2_hub" and "is_uv3_hub".
