commit09eea7ad0bupstream. There are use cases that interrupt and monitor pages are mapped to user-mode through UIO, so they need to be system page aligned. Some Hyper-V allocation APIs introduced earlier broke those requirements. Fix this by using page allocation functions directly for interrupt and monitor pages.
