The new usb_control_msg_send() nicely wraps usb_control_msg() with proper

There are many usages of usb_control_msg() that can use the new wrapper
functions usb_contro_msg_send() & usb_control_msg_recv() for better
error checks on short reads and writes. Hence use them whenever possible
and avoid using usb_control_msg() directly.

Hyper-V assumes page size to be 4K. This might not be the case for ARM64
architecture. Hence use hyper-v page size and page allocation function
to avoid conflicts between different host and guest page size on ARM64.
