| |
From: Geoff Levand <geoffrey.levand@am.sony.com>
This patch removes the incorrect Cell processor setup routine __setup_cpu_be. This routine improperly accesses the hypervisor page size configuration at SPR HID6. The correct behavior is for firmware, or if needed, platform setup code, to set the correct page size.
