The following commit has been merged in the linux branch: commit a66c2edea56c291a6f6a52f07496ebb97c0880e8 Author: Paul Mundt lethal@linux-sh.org Date: Wed Oct 14 14:14:30 2009 +0900
sh: Populate initial secondary CPU info from boot_cpu_data.
The secondary CPU info was seeing corrupted results due to not entering all of the setup paths taken by the boot CPU. So we just memcpy() the boot cpu data over directly, and then fix up the per-CPU bits.
