From 59f148005cfd3d41537a4b872c266213d5fe4dc6 Mon Sep 17 00:00:00 2001 From: Brent Casavant Date: Tue, 17 Oct 2006 00:09:25 -0700 Subject: [PATCH] [PATCH] ioc4: Enable build on non-SN2 The SGI PCI-RT card, based on the SGI IOC4 chip, will be made available on Altix XE (x86_64) platforms in the near future. As such it is now a misnomer for the IOC4 base device driver to live under drivers/sn, and would complicate builds for non-SN2. This patch moves the IOC4 base driver code from drivers/sn to drivers/misc, and updates the associated Makefiles and Kconfig files to allow building on non-SN2 configs. Due to the resulting change in link order, it is now necessary to use late_initcall() for IOC4 subdriver initialization.
