[Xen-ia64-devel] [PATCH] Provides right frequency ratio and base for VTi domain

["Zhang, Xiantao" <xiantao.zhang@xxxxxxxxx>]

Hi Dan /Alex,
        This patch handles the pal_freq_ratio request breaked to Xen by GFW for 
VTi domain. and it fixed the wrong frequency_ratio of VTi domian.So,with this 
patch, VTi domain can get the right time , itc, cpu frequency and other kernel 
params rely on right frequency_ratio. Please help to check in.

Thanks
