If RAM disk driver initialization fails due to blk_alloc_queue() faulure, the
gendisk structs stored in rd_disks[] will not be freed completely.
This patch resolves that memory leak case by doing alloc_disk() and
blk_alloc_queue() at the same time.

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.

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 dependencies on
SN2-specific features and config dependencies need to be removed.
This patch updates the Kconfig files to remove the config dependency, and
updates the IOC4 bus speed detection routine to use universally available
time interfaces instead of mmtimer.

I could not get correct PCI Express bus number from the structure of
acpi_object_extra. I always get zero as bus number regardless of bus
location. I found that there is incorrect comparison with _HID (PNP0A08) in
acpi/events/evrgnini.c and PCI Express _BBN method always fail.
Therefore, we always get zero as PCI Express bus number.
