This makes saved_max_pfn not be passed down to 2nd kernel. To keep 1st kernel and 2nd kernel using the same TCE table size, Muli suggest to hard code the size to max (8M). We can't get rid of saved_max_pfn this time, for backward compatibility with old first kernel and new second kernel. However new first kernel and old second kernel can not work unfortunately. v2->v1: - retain saved_max_pfn so new 2nd kernel can work with old 1st kernel from Vivek Signed-off-by: WANG Chao Acked-by: Vivek Goyal Acked-by: Muli Ben-Yehuda Acked-by: Jon Mason Link: http://lkml.kernel.org/r/1394463120-26999-1-git-send-email-chaowang@redhat.com Signed-off-by: H.
