Stephen Rothwell f057eac0d7 Introduce CONFIG_VIRT_TO_BUS
Make some offending drivers depend on it and set CONFIG_ARCH_NO_VIRT_TO_BUS
for ppc64 so that we don't build those drivers.

This gets PowerPC allmodconfig and allyesconfig much closer to building.

Matthias Kaehlcke 9ac162521c Use mutexes instead of semaphores in I2O driver
The I2O driver uses two semaphores as mutexes.  Use the mutex API instead of
the (binary) semaphores.

Eric Moore cc78d30af0 [SCSI] mpt fusion: fix for mounted raid volume filesytem that goes read-only
If there is IO going to the volume while a hidden disk is being torn down,
there is a case where we would return a DID_NO_CONNECT for IO sent to the
volume. The end result is the volume goes read-only. This problem is due to the
fact the firmware mapped target ids saved in per device object is phys_disk_num
for hidden  raid components, and target_id for the volume. There is a single
case when both phys_disk_num and target_id are equal, so enters this issue. We
fix this issue by checking the tflags when the device is torned down,
insuring the IO being completed is meant for hidden raid component, not the
volume.  In addition to this fix, there are a couple other cases to address
hidden raid components. For instance task_abort and device reset are not
supported by mpt fw for hidden raid components, a bus reset would be required
or target reset to volume.

Doug Chapman 29982e9acd [SCSI] fusion: fix for BZ 8426 - massive slowdown on SCSI CD/DVD drive
Patch for: http://bugzilla.kernel.org/show_bug.cgi?id=8426

A recent code cleanup that moved code from mptscsih to mptspi
inadvertently change the order some code was called.  This caused
a massive slowdown (of 150x to 300x) on the CD/DVD drive on the
high-end HP Integrity servers.
