Analyze and fix the following issue in the Linux kernel code: [PATCH] ppc: Fix boot with yaboot with ARCH=ppc
Problem Details: The merge of machine types broke boot with yaboot & ARCH=ppc due to the old code still retreiving the old-syle machine type passed in by yaboot. This patch fixes it by translating those old numbers. Since that whole mecanism is deprecated, this is a temporary fix until ARCH=ppc uses the new prom_init t...
