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
