Subject: [PATCH 04/13] cell: remove broken __setup_cpu_be function

From: Arnd Bergmann <[email-masked]>
Date: Sun, 30 Apr 2006 01:28:16 +0200

From: Geoff Levand <[email-masked]>

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.
