Long Li 734226f482 Drivers: hv: Allocate interrupt and monitor pages aligned to system page boundary ...

commit 09eea7ad0b upstream.

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.
