virtio wants to read bitwise types from userspace using get_user. At the

A message was using pr_info level output for a message including "ERROR"
which is not really a fatal error.
Remove the 'ERROR' from that message, use pr_warn loglevel and add the
function name to the output to give users a chance to find the culprit
in case the warning triggers.

PVR version code was missing in the cpu_ver_lookup table for the following
versions: 8.50.b 8.50.c 9.2 9.3
This caused /proc/cpuinfo to display "CPU-Ver: Unknown" for these versions.
This was detected and the patch tested with MicroBlaze version 8.50.c.
The other codes were taken from the Xilinx MicroBlaze Processor Reference
Guides UG081 (v14.7) and UG984 (v2014.1).

There is no need to repeat the work that is already done in the PCI

callbacks.
Note that there is no more calls performed to enable or disable a PCI
device during suspend-resume cycle. Nowadays they seems to be
superflous. Someone can read more in [1].

The work queue couldn't reliably prevent the SW ring buffer from
overflowing, so dmesg was spammed by
kfd kfd: Interrupt ring overflow, dropping interrupt.
messages when running e.g. the Atlantis Substance demo from
https://wiki.unrealengine.com/Linux_Demos on Kaveri.
Since the SW ring buffer doesn't actually do anything at this point, just
remove it for now. When actual interrupt processing code is added to
amdkfd, it should try to do things immediately and only defer to work
queues when necessary.

Add nand_shutdown to wait for current nand operations to finish and prevent
further operations by changing the nand flash state to FL_SHUTDOWN.
This is addressing a problem observed during reboot tests using UBIFS
root file system: NAND erase operations that are in progress during
system reboot/shutdown are causing partial erased blocks. Although UBI should
be able to detect and recover from this error, this change will avoid
the creation of partial erased blocks on reboot in the middle of a NAND erase
operation.

- Complete overhaul to the main IOCTL function, kfd_ioctl(), according to
drm_ioctl() example. This includes changing the IOCTL definitions, so it
breaks compatibility with previous versions of the userspace. However,
because the kernel was not officialy released yet, and this the first
kernel that includes amdkfd, I assume I can still do that at this stage.
- A couple of bug fixes for the non-HWS path (used for bring-ups and
debugging purposes only).

The sh73a0 INTC can't mask interrupts properly most likely due to a
hardware bug. Set the .control_parent flag to delegate masking to the
parent interrupt controller, like was already done for irqpin1.
Without this, accessing the three-axis digital accelerometer ADXL345
on kzm9g through /dev/input/event1 causes an interrupt storm, which
requires a power-cycle to recover from.
This was inspired by a patch for arch/arm/boot/dts/sh73a0.dtsi from
