[PATCH v2 0/2] hyperv: Move some features to common code

There are several bits of Hyper-V-related code that today live in arch/x86 but are not really specific to x86_64 and will work on arm64 too. Some of these will be needed in the upcoming mshv driver code (for Linux as root partition on Hyper-V). So this is a good time to move them to drivers/hv. S

[PATCH v2 1/2] hyperv: Move hv_current_partition_id to arch-generic code

From: Nuno Das Neves Move hv_current_partition_id and hv_get_partition_id() to hv_common.c. These aren't specific to x86_64 and will be needed by common code. Set hv_current_partition_id to HV_PARTITION_ID_SELF by default. Use a stack variable for the output of the hypercall. This allows moving

[PATCH v2] scsi: storvsc: Set correct data length for sending SCSI command without payload

From: Long Li In StorVSC, payload->range.len is used to indicate if this SCSI command carries payload. This data is allocated as part of the private driver data by the upper layer and may get passed to lower driver uninitialized. For example, the SCSI error handling mid layer may send TEST_UNIT_
