I compiled the RC1 of kernel 5.9 today. Unfortunately the issue with the
VirtIO-GPU (see below) still exists. Therefore we still need the patch
(see below) for using the VirtIO-GPU in a virtual e5500 PPC64 QEMU machine.
Could you please check the first bad commit?

The new field 'dma_range_map' in struct device is used to facilitate the
use of single or multiple offsets between mapping regions of cpu addrs and
dma addrs. It subsumes the role of "dev->dma_pfn_offset" which was only
capable of holding a single uniform offset and had no region bounds
checking.
Patchset Summary:
Enhance a PCIe host controller driver. Because of its unusual design
we are foced to change dev->dma_pfn_offset into a more general role
allowing multiple offsets. See the 'v1' notes below for more info.

for a 32 bit overflow so cast bl_pwm to enforce a 64 bit shift operation
to avoid this.

This patch fixes a few bugs:
1- We weren't taking into account sha_leftovers when adding multiple
ksvs to sha_text. As such, we were or'ing the end of ksv[j - 1] with
the beginning of ksv[j]
2- In the sha_leftovers == 2 and sha_leftovers == 3 case, bstatus was

Instead of hand rolling the transfer ourselves in the hdcp hook, inspect
aux messages and add the aksv flag in the aux transfer hook.
IIRC, this was the original implementation and folks wanted this hack to
be isolated to the hdcp code, which makes sense.
However in testing an

On HDCP disable, clear the repeater bit. This ensures if we connect a
non-repeater sink after a repeater, the bit is in the state we expect.

Only one functional change, reversed the hdcp_1x/2x_present bits in the
QUERY_STREAM_ENCRYPTION_STATUS parsing with a comment explaining my
confusion.
Other than that, lots of rebasing, the most notable being the
s/intel_dig_port/dig_port/ rename.

Use alpha value to blend source value and destination value Instead of
just overwrite with source value.

This is a bit of housecleaning for a future patch. Instead of sprinkling
hdcp->value assignments and prop_work scheduling everywhere, introduce a
function to do it for us.

This patch is required for HDCP over MST. If a port is being used for
multiple HDCP streams, we don't want to fully disable HDCP on a port if

This patch adds some protection against connectors being destroyed
before the HDCP workers are finished.
For check_work, we do a synchronous cancel after the connector is
unregistered which will ensure that it is finished before destruction.
In the case of prop_work, we can't
