[PATCH v2 0/1][SRU][OEM-5.17][OEM-6.0] Screen freeze after resuming from suspend (nvme0: I/O timeout)

[AceLan Kao]

From: "Chia-Lin Kao (AceLan)" <acelan.kao at canonical.com>

[Impact]
The system hangs after S3 with VMD mode is on.

[Fix]
Intel provides a fix and still under discussion
https://patchwork.kernel.org/project/linux-pci/patch/20221107182735.381552-1-francisco.munoz.ruiz@linux.intel.com/

The patch is not finalized, so submit SRU to OEM kernels only, and will
submit to other series kernels once the patch is accepted by upstream.

[Test]
Verified by us and ODM.

[Where problems could occur]
The VMCONFIG_MSI_REMAP bit is missing after S3, set it back won't lead to
any regression.
